“Frailty” is associated with worse outcomes in adult cardiology. There is limited data on the associations between frailty and outcomes in paediatric cardiology. We aimed to define the prevalence of frailty and identify associations between frailty and neurodevelopmental and quality-of-life outcomes in high-risk paediatric cardiac populations.

This cross-sectional study included patients 4–18 years seen in a neurodevelopmental programme between 6/2017 and 11/2022. Demographic and clinical data were obtained from medical records. As part of the routine care, physical therapy assessment and neurocognitive, psychosocial, adaptive functioning, and quality-of-life surveys were administered. Social determinants of health were assessed by insurance status and Childhood Opportunity Index. Frailty was defined as the abnormality in 3 of 5 categories: body composition, weakness, slowness, physical activity, and exhaustion. Chi-Square, Student t, and Wilcoxon Rank Sum tests were used to assess differences between frail and non-frail groups.

Of the 270 patients, 101 (37%) met the frailty criteria. Frailty was not associated with social determinants of health, cardiac diagnosis, genetic syndrome, number of cardiac surgeries, or history of clinical complications. Frail patients were more likely to be older (p = 0.004) and have neurocognitive (p = 0.024), emotional (p = 0.003), social (p < 0.001), motor (p < 0.001), and adaptive dysfunction (p < 0.001) and lower quality of life (p = 0.029).

Frailty is common in school-aged patients with cardiac disease and is associated with adverse neurocognitive, psychosocial, motor, and adaptive outcomes and worse quality of life. Risk stratification for frailty may be a critical evaluation and screening element of high-risk cardiac patients in neurodevelopmental programmes.

In paediatric cardiac patients requiring staged palliation, superior cavopulmonary anastomosis is common. Pain control is a crucial aspect of postoperative care as agitation, untreated pain, and hypoventilation can cause increased pulmonary vascular resistance reduction and pulmonary blood flow.

This was a large volume single-centre, retrospective cohort study evaluating the impact of gabapentin on opioid and benzodiazepine exposure in infants undergoing superior cavopulmonary anastomosis between January 2018 and December 2022. The primary endpoint was opioid exposure in morphine milligram equivalents per kilogram in infants receiving gabapentin compared to no gabapentin.

The study analysed 85 infants, 40 of which received perioperative gabapentin. Other than there being more males in the gabapentin group (70% versus 47%; p = 0.03), there was no difference in baseline characteristics. Opioid use, measured in morphine milligram equivalents per kilogram, was similar in the no gabapentin group compared to the gabapentin group during the first 5 POD’s (2.66 (interquartile range1.76, 3.30) versus 2.27 (interquartile range R 1.75, 3.40); p = 0.93. However, there was a lower benzodiazepine exposure, measured in midazolam equivalents per kilogram, in the gabapentin group both on POD 2 (0.05 (interquartile range 0.00, 0.11) versus 0 (interquartile range 0.00, 0.08); p = 0.031) and cumulative (0.15 (interquartile range 0.00, 0.35) versus 0.05 (interquartile range 0.00, 0.15); p = 0.031).

Gabapentin did not significantly reduce opioid exposure; however, its use was associated with modest reduction in benzodiazepine exposure. There were no differences in adverse events. Our findings suggest gabapentin is safe in infants undergoing superior cavopulmonary anastomosis; however, additional studies should be conducted to evaluate optimal gabapentin dosing.

Despite advances in treatment and outcomes for paediatric heart failure, both physical and psychosocial comorbidities remain notable among this patient population. We aimed to qualitatively describe the psychosocial experiences of adolescent and young adults with heart failure and their caregivers’ perceptions, with specific focus on personal challenges, worries, coping skills, and resilience.

Structured, in-depth interviews were performed with 16 adolescent and young adults with heart failure and 14 of their caregivers. Interviews were recorded and transcribed. Content analysis was performed, and themes were generated. Transcripts were coded by independent reviewers.

Ten (63%) adolescent and young adults with heart failure identified as male and six (37.5%) patients self-identified with a racial or ethnic minority group. Adolescent and young adults with heart failure generally perceived their overall illness experience more positively and less burdensome than their caregivers. Some adolescent and young adults noted specific worries related to surgeries, admissions, major complications, death, and prognostic/treatment uncertainty, while caregivers perceived their adolescent and young adult’s greatest worries to be around major complications and death. Adolescent and young adults and their caregivers were able to define and reflect on adolescent and young adult experiences of resilience, with many adolescent and young adults expressing a sense of optimism and gratitude as it relates to their medical journey.

This study is the first of its kind to qualitatively describe the psychosocial experiences of a racially and socioeconomically diverse sample of adolescent and young adults with heart failure, as well as their caregivers’ perceptions of patient experiences. Findings underscore the importance of identifying distress and fostering resilient processes and outcomes in young people with advanced heart disease.

Catheter ablation is now the preferred early treatment option in children due to its high success rate and low complication rate. The aim of this study was to evaluate the outcomes of patients who underwent electrophysiology studies and a catheter ablation procedure in our centre.

Paediatric patients who underwent catheter ablation in our hospital between 2017 and 2024 and were followed up or referred for ablation from another centre were retrospectively screened. Patients who had an intracardiac defibrillator, pacemaker, or ventricular arrhythmia were excluded from the study. The data were screened from a total of 586 patients (M/F = 300/286). The procedure was applied to 288 (49 %) patients with atrioventricular re-entry tachycardia (Wolf Parkinson White 86.4%-n:249; occult accessory pathway 13.9%- n:39), and to 270 (45%) with atrioventricular nodal re-entry tachycardia. Eleven (1.8%) patients with focal atrial tachycardia, 11 (1.8%) with frequent extrasystole or ventricular tachycardia, 6 (1%) with supraventricular premature beat (SVE), and 2 patients with a Mahaim diagnosis underwent the procedure. Fluoroscopy was used during the procedure in 75 (12.8%) patients, and the mean duration of fluoroscopy was 5.2 ± 3.2 mins (range 0.2–19.6 mins). Of these 75 patients, trans-septal punction was performed on the left side for the procedure to be applied in 71 patients. Of the patients diagnosed with atrioventricular re-entry tachycardia, fluoroscopy was used in 4.

The results of this study of catheter ablation performed at our institution have shown acute success and recurrence rates similar to those of previously published studies.

Several organizations including the Environmental Protection Agency, World Health Organization and American Academy of Pediatrics recommend that hospital sound levels not exceed 45 decibels. Yet, several studies across multiple age groups have observed higher than recommended levels in the intensive care setting. Elevated sound levels in hospitals have been associated with disturbances in sleep, patient discomfort, delayed recovery, and delirium.

We measured sound levels in a pediatric cardiac intensive care unit and collected vital signs data, sedation dosing and delirium scores. During a 5-week study period, sound levels for 68 patients in 22 private and 4 semi-private rooms were monitored.

Sound levels were consistently above stated recommendations with an average daytime level of 50.6 decibels (maximum, 76.9 decibels) and an average nighttime level of 49.5 decibels (maximum, 69.6 decibels). An increase in average and maximum sound levels increased the probability of sedation administration the following hour (p-value < 0.001 and 0.01, respectively) and was predictive of an increase in heart rate and blood pressure (p-value < 0.001).

Sound levels in the CICU were consistently higher than recommended. An increase in heart rate, blood pressure and sedation utilization may suggest a stress response to persistent and sudden loud sounds. Given known negative impacts of excessive noise on stress, sleep, and brain development, as well as the similar adverse effects from the related use of sedative medications, reducing excessive and sudden noise may provide an opportunity to improve short- and long-term hemodynamic and neurodevelopmental outcomes in the pediatric cardiac intensive care unit.

Dexmedetomidine is frequently used in paediatric anaesthesia. This includes use in patients with CHD, but detailed analysis of haemodynamics after administration in these patients has not yet been published. We performed a systematic review and meta-analyses examining haemodynamic changes immediately after dexmedetomidine administration in patients with CHD.

We conducted a systematic review of PubMed, Embase, and Medline from inception until May 31, 2024. Inclusion criteria were studies that contained children with CHD who received dexmedetomidine for a cardiac procedure and reported at least one haemodynamic variable before and after administration of dexmedetomidine. Exclusion criteria were studies of noncardiac procedures. We performed a meta-analysis on each haemodynamic variable that was reported by at least four studies.

We screened 5383 abstracts. We included 85 studies for review, and 16 studies were accepted for four meta-analyses (heart rate, 16 studies, n = 408; systolic blood pressure, 11 studies, n = 280; diastolic blood pressure, 10 studies, n = 276; mean arterial pressure, 5 studies, n = 130). Analysis of heart rate, systolic blood pressure, and diastolic blood pressure showed a statistically significant reduction (p < 0.001), while there was no significant change in mean arterial pressure. The clinical difference was minimal with a decrease in heart rate of 11.3 beats per minute, and a decrease in systolic blood pressure/diastolic blood pressure of 5.9 and 6.2 mmHg, respectively. Heterogeneity was high in all analyses.

Dexmedetomidine is associated with small changes in heart rate, systolic blood pressure, and diastolic blood pressure in children with CHD. Further study is warranted.

Primary pulmonary vein stenosis is a rare congenital heart condition and carries a poor prognosis. Various surgical techniques have been introduced to treat primary pulmonary vein stenosis. However, there is no consensus on the optimal approach. This study aimed to evaluate the outcomes of surgical treatment of primary pulmonary vein stenosis, identify the risk factors for pulmonary vein restenosis and reintervention, and determine the optimal strategy for primary pulmonary vein stenosis repair.

From December 2008 to December 2023, 64 patients with primary pulmonary vein stenosis undergoing surgical repair in our institution were included [non-sutureless group, n = 42; sutureless group, n = 22]. The Cox proportional hazard model was used to identify risk factors for pulmonary vein restenosis and pulmonary vein restenosis-related reintervention.

There were three in-hospital deaths and one late death. The survival rates at 1, 5, and 15 years were 91.9%, 84.2%, and 69.8%, respectively, in the whole cohort. Compared with the non-sutureless group, the sutureless group did not significantly improve the long-term survival of primary pulmonary vein stenosis patients (P = 0.484). Pulmonary vein restenosis occurred in 15 patients. Multivariable analysis showed that Involvement of the left inferior pulmonary vein (P < 0.001) was the only independent risk factor for pulmonary vein restenosis, while sutureless repair (P = 0.037) was a protective factor. Pulmonary vein restenosis-related reintervention occurred in 12 patients. On multivariate analysis, three or four pulmonary veins involvement (P = 0.001) and preoperative severity score exceeding 5 (P = 0.050) were found to be independent risk factors associated with pulmonary vein restenosis-related reintervention; however, sutureless repair (P = 0.021) was a protective factor.

Management of infants with primary pulmonary vein stenosis is challenging. Surgical repair of primary pulmonary vein stenosis can be safely achieved using different techniques, with similar long-term mortality. Compared with non-sutureless repair, sutureless repair was significantly associated with decreased pulmonary vein restenosis and decreased pulmonary vein restenosis-related reintervention, respectively. Preoperative severity score exceeding 5, 3, or 4 pulmonary veins involvement, and left inferior pulmonary vein involvement are independent risk factors for adverse outcomes.

Data on aortic valve outcomes following surgical repair of doubly committed subarterial ventricular septal defect remain limited.

This retrospective study included doubly committed subarterial ventricular septal defect patients who underwent surgical repair at our centre from 2013 to 2023. The primary outcome was the incidence of new-onset aortic regurgitation during follow-up.

A total of 320 patients were included, with a median age of 2.0 (0.9–7.2) years. Among them, 289 patients underwent surgical repair alone (repair group), and 31 received additional aortic valve surgery (repair + aortic valve surgery group). Preoperatively, 58 (18.1%) patients exhibited aortic regurgitation ≥ mild (10.7% in the repair group vs 87.1% in the repair + aortic valve surgery group, P < 0.001). The overall median follow-up was 40.5 (16.0–72.0) months. At the last follow-up, 23 (7.4%) patients had aortic regurgitation ≥ mild (3.8 vs 52.2%, P < 0.001), and 6 (1.9%) had aortic regurgitation > mild (0.3 vs 21.7%, P < 0.001). Sixteen (5.1%) patients developed new-onset aortic regurgitation during follow-up (1.7 vs 47.8%, log-rank P < 0.001), and 6 (1.9%) of them developed new-onset aortic regurgitation > mild (0.3 vs 21.7%, log-rank P < 0.001). Age, ventricular septal defect size, preoperative aortic regurgitation > mild, and maximum aortic valve flow velocity (AVmax) were related to concurrent aortic valve surgery and new-onset aortic regurgitation.

Based on our retrospective data, the mid-term aortic valve outcomes after doubly committed subarterial ventricular septal defect repair were relatively satisfactory, with a low incidence of new-onset aortic regurgitation during follow-up. However, aortic valve outcomes for patients who received concurrent aortic valve surgery were less satisfactory.

To describe the experience of a series of paediatric patients with Fontan-associated liver dysfunction.

A retrospective study including 12 patients with Fontan-associated liver disease. Patients were selected from the single-ventricle program at a high-complexity centre in Colombia between 2001 and 2024.

During the study period, 108 patients were in the Fontan stage. Among them, 12 met the criteria for Fontan-associated liver disease (11.1%). The median age at extracardiac Fontan completion was 3.9 years, while the median age at Fontan-associated liver disease diagnosis was 14.5 years. Concomitant protein-losing enteropathy and/or plastic bronchitis were present in 33% of cases. Echocardiographic follow-up showed systolic dysfunction in 41% and diastolic dysfunction in 16% of patients. All patients exhibited some degree of valvular insufficiency, mild in 83.3% and moderate in 16%. Haemodynamic variables at the time of diagnosis did not show significant abnormalities.

Liver disease is a persistent concern in paediatric patients with Fontan physiology, posing diagnostic and therapeutic challenges. Healthcare professionals managing these patients should be aware of its early identification and appropriate treatment.

Right anterolateral thoracotomy or left anterolateral thoracotomy applied to partial anomalous pulmonary venous connection correction have been reported to obtain cosmetic and less invasive outcomes as alternative approaches to median sternotomy. However, the application of different approaches is still confusing. We compared the perioperative and mid-term outcomes to seek indications of different approaches and guide surgical treatment of partial anomalous pulmonary venous connection.

From July 2019 to August 2023, 44 patients who underwent surgical correction of partial anomalous pulmonary venous connection were recruited. Of these, 13 (29.6%) patients who underwent median sternotomy were separated into M group, 28 (63.6%) patients who underwent right anterolateral thoracotomy were separated into R group, and three (6.8%) patients who underwent left anterolateral thoracotomy were separated into L group. Clinical data were reviewed and compared between each group.

In M group, direct anastomosis accounted for the most (7, 53.8%), in R group, intra-atrial rerouting accounted for the most (22, 78.6%), and in L group, direct anastomosis accounted for the most (3, 100%). R group had shorter cardiopulmonary bypass time (70.0 ± 32.4 vs113.1 ± 83.3, p = 0.029), shorter ICU stay (1.0 ± 0.2 vs 1.9 ± 1.7, p = 0.01), shorter postoperative stay (6.0 ± 1.2 vs 8.3 ± 5.0, p = 0.021), and fewer chest tube drainage (8.4 ± 4.3 vs 13.9 ± 10.2, p = 0.026) compared with M group. Three left-sided partial anomalous pulmonary venous connection in L group adopted off-pump approach.

Median sternotomy S.V.C. can be applicable to all anatomic types of partial anomalous pulmonary venous connection especially for complex types. Considering the minimally invasive advantages, we prefer applying right anterolateral thoracotomy for pulmonary vein connected to right atrium or proximal end of off-pump. Applying left anterolateral thoracotomy for left-sided partial anomalous pulmonary venous connection without atrial septal defect by off-pump.

The sutureless repair technique has been favoured due to its purported reduction in post-operative pulmonary venous obstruction rates. This study aims to compare the outcomes of conventional versus sutureless repair techniques in Total Anomalous Pulmonary Venous Drainage.

In this retrospective single-centre analysis (2012–2022), we evaluated children who underwent conventional or sutureless repair for isolated total anomalous pulmonary venous drainage, excluding complex cardiac anomalies and incomplete data. Patients were categorised into conventional (Group C, n = 58) and sutureless (Group S, n = 41) groups. Primary outcomes included mortality, morbidity, and post-operative complications. Statistical analysis included Mann–Whitney U, chi-square, and Fisher’s exact tests where appropriate.

Supracardiac type predominated in both groups (53.4% in Group C and 70.7% in Group S), with higher cardiac type frequency in Group C (24.1% versus 2.4%, p = 0.016). Early complications occurred in 58.5% versus 53.4% of cases in Groups S and C, respectively (p = 0.767). The mortality rate (17.2% versus 14.6%, p = 0.944) and post-operative pulmonary venous obstruction (21.2% versus 19.0%, p = 0.809) were higher in Group C, though not significantly. Mean cardiopulmonary bypass times were comparable between groups (105 versus 89 minutes, p = 0.424).

In this comprehensive analysis of paediatric Total Anomalous Pulmonary Venous Drainage repair, both conventional and sutureless techniques demonstrated comparable safety profiles and clinical outcomes. These findings suggest that surgical approach selection should be individualised based on patient characteristics and surgeon expertise. Further prospective studies with larger cohorts are needed to validate these observations.

We aimed to evaluate the clinical and laboratory characteristics and aetiological factors of patients who underwent pericardiocentesis for moderate to large pericardial effusion.

A total of 38 patients who underwent pericardiocentesis due to moderate-severe pericardial effusion and not related to cardiac surgery were included in the study.

The male-to-female ratio was 2.16, and found to be 7.5 in patients over 3 years of age. Mean age and body weight of the patients were 69.4 ± 74.9 months and 22.5 ± 22.4 kg. Dyspnoea (51.7%) was the most common complaint, followed by chest pain (37.9%). Tamponade was present in 23.7% of the patients. The largest diameter of effusion was 24.4 ± 10.4 mm. The amount of fluid drained was 279.24 ± 279 ml. Macroscopic appearance was serous in 12 (34.3%), and haemorrhagic in 18 (51.4%). No complication related to procedure was seen. Aetiology for efusion was infectious in 26%, idiopathic in 18%, iatrogenic in 11%, rheumatological in 11%, malignancy in 8%, cardiomyopathy in 8%, and other factors related in 18%. Of the 38 patients, 16 received nonsteroidal anti-inflammatory drugs (NSAID), and colchicine and corticostreoid were added in nine and two patients, respectively. A total of eight (21%) patients died during follow-up.

In conclusion, percutaneous pericardiocentesis can be applied safely and the underlying aetiology is decisive in the prognosis of the patient. Although pericardial effusion in children is often due to inflammation of the pericardium, it can develop as a finding of many local or systemic diseases that should be kept in mind.

Integrating psychosocial health services into paediatric surgical specialty care is essential for addressing behavioural and psychological aspects of illness and reducing healthcare disparities. This is crucial for patients facing CHD, who are at higher risk for depression, anxiety, and attention-deficit/hyperactivity disorder, which is significantly influenced by their caregivers’ mental well-being.

The Pediatric Psychosocial Preventative Health Model framework was utilised by a psychosocial team to assess biopsychosocial needs in CHD patients during their first cardiac surgery evaluations. Patient and family needs were categorised into universal, targeted, and clinical tiers, allowing for responsive interdisciplinary services. Screening tools such as the Psychosocial Assessment Tool, Pediatric Quality of Life Inventory, and Depression, Anxiety, and Stress Scales were used during initial consultations to guide appropriate interventions and referrals.

Universal-tier patients received comprehensive support focused on preventive measures, resource access, and education to promote resilience. Targeted-tier care involved intensive, collaborative efforts, providing specialized psychological evaluations, and one-on-one time with experts. Clinical-tier families required specialised, intensive interventions such as advanced cognitive behavioural therapy and medication management. The Pediatric Psychosocial Preventative Health Model framework and psychosocial team workflow allow for individualised management strategies, ensuring that each family received timely and appropriate interventions based on their unique needs.

Integrating psychosocial services into initial surgical evaluations is critical for addressing CHD patients’ psychological and social needs, promoting an interdisciplinary approach that enhances overall family functioning and well-being.

Current research suggests that a small pulmonary artery can cause adverse events and reduce exercise capacity after the Fontan procedure. This study aimed to evaluate the impact of pulmonary artery size on early haemodynamic and laboratory variables after total cavopulmonary connection.

We reviewed all patients who underwent staged Fontan between 2012 and 2022. Pulmonary artery index before bidirectional cavopulmonary shunt and before total cavopulmonary connection was calculated according to Nakata and colleagues. We sought to analyse the impact of the pulmonary artery index on early haemodynamic and laboratory variables, including pulmonary artery pressure and mean arterial pressure 12 hours after extubation and lactate levels 6 hours after extubation.

A total of 263 patients were included. Median age and weight at total cavopulmonary connection were 2.2 (interquartile ranges: 1.8–2.7) years and 11.7 (interquartile range: 10.7–13.3) kg, respectively. Before that, all patients underwent bidirectional cavopulmonary shunt at a median age of 4.1 (interquartile range: 3.2–5.8) months. In the multivariable analysis, pre-bidirectional cavopulmonary shunt pulmonary artery index (p = 0.016, odds ratio 0.993), with a cut-off value of 154 mm2/m2 was an independent risk factor for a higher pulmonary artery pressure (> 17 mmHg). No variable was identified as a significant risk factor for lower mean arterial pressure (< 57 mmHg). Regarding lactate levels (> 4.5 mg/dl), pre-bidirectional cavopulmonary shunt right pulmonary artery index (p < 0.001, odds ratio 0.983), with a cut-off value of 70 mm2/m2 was identified as an independent risk factor.

In patients with staged Fontan palliation, a small pulmonary artery size before bidirectional cavopulmonary shunt and total cavopulmonary connection was a determinant factor associated with unfavourable early postoperative haemodynamics after total cavopulmonary connection.

Persistent pulmonary hypertension of the newborn is a serious disease with significant morbidity and mortality. Magnesium sulphate has been proposed as a potential treatment for persistent pulmonary hypertension of the newborn, but its efficacy remains unclear. The article aims to evaluate the effects of magnesium sulphate on persistent pulmonary hypertension of the newborn.

A comprehensive search of PubMed, Web of Science, Embase, and Cochrane Library was conducted to identify relevant studies. The primary outcomes were pulmonary artery pressure and oxygenation index, while secondary outcomes included mean blood pressure, alveolar-arterial oxygen difference, arterial partial pressure of oxygen (PaO2), arterial partial pressure of carbon dioxide (PaCO2), and arterial oxygen saturation. Statistical analysis was performed by Cochrane Review Manager 5.3.

The study analysed twelve studies involving 380 patients. Results indicated that magnesium sulphate treatment significantly reduced pulmonary artery pressure levels (MD −24.96, 95% CI −28.19 to −21.73, P < 0.0001) and mean blood pressure (MD −3.11, 95% CI −3.91 to −2.32, P < 0.0001) compared to pretreatment. Additionally, it led to a notable decrease in oxygenation index (P < 0.00001) and alveolar-arterial oxygen difference (P < 0.0001), while increasing PaO2 (P < 0.0001) and arterial oxygen saturation (P < 0.001). However, there was no significant effect on PaCO2 levels compared to pretreatment.

Magnesium sulphate is a valuable therapy for persistent pulmonary hypertension of the newborn. It markedly reduced pulmonary artery pressure, alveolar-arterial oxygen difference, and oxygenation index, while enhancing PaO2, and arterial oxygen saturation, with no impact on PaCO2 levels. Magnesium sulphate may also reduce mean blood pressure following a 2-hour treatment. Additional studies are necessary to further clarify its efficacy and potential side effects.

This study was registered with PROSPERO (CRD42024578092).

This study explored the prospective use of the Ages and Stages Questionnaires-3 in follow-up after cardiac surgery.

For children undergoing cardiac surgery at 5 United Kingdom centres, the Ages and Stages Questionnaires-3 were administered 6 months and 2 years later, with an outcome based on pre-defined cut-points: Red = 1 or more domain scores >2 standard deviations below the normative mean, Amber = 1 or more domain scores 1–2 standard deviations below the normal range based on the manual, Green = scores within the normal range based on the manual.

From a cohort of 554 children <60 months old at surgery, 306 participated in the postoperative assessment: 117 (38.3%) were scored as Green, 57 (18.6%) as Amber, and 132 (43.1%) as Red. Children aged 6 months at first assessment (neonatal surgery) were likely to score Red (113/124, 85.6%) compared to older age groups (n = 32/182, 17.6%). Considering risk factors of congenital heart complexity, univentricular status, congenital comorbidity, and child age in a logistic regression model for the outcome of Ages and Stages score Red, only younger age was significant (p < 0.001). 87 children had surgery in infancy and were reassessed as toddlers. Of these, 43 (49.2%) improved, 30 (34.5%) stayed the same, and 13 (16.1%) worsened. Improved scores were predominantly in those who had a first assessment at 6 months old.

The Ages and Stages Questionnaires results are most challenging to interpret in young babies of 6 months old who are affected by complex CHD.

Although isolated ductus arteriosus aneurysm has been reported as 0.8% in autopsy series, it has recently been reported as up to 8.8% with increased awareness. Most cases are asymptomatic and regress spontaneously. In this study, we aimed to evaluate the characteristics, clinical manifestations, and outcomes of ductus arteriosus aneurysm in neonates.

A total of 22 newborns with echocardiographic images recorded in the hospital registry system were identified to have a ductus arteriosus aneurysm. The demographic, clinical, and echocardiographic findings of the patients were extracted from the hospital records.

The mean gestational age and weight at birth of the newborns were 38 6/7 weeks (35 3/7 – 40 6/7 weeks) and 3203 g (2445–4080 g), respectively. The maximal length and width of the aneurysm ranged from 6 to 21 mm and 5.3 to 13 mm, respectively. In three of the patients, thrombus in the aneurysm was detected on the third day of life, leading to surgical excision of thrombus and ligation of the aneurysm in two. In the remaining 19 patients, the aneurysm regressed spontaneously and closed in an average of 5.3 days.

With increased awareness and earlier and more frequent application of echocardiography in newborns, the diagnosis of ductus arteriosus aneurysm is being reported more frequently. The most common scenario is spontaneous regression, however, it should not be forgotten that it can lead to serious complications, as reported previously. In selected cases, surgical treatment may be an option to prevent more serious or late complications, though the indications for surgical intervention remain unclear.
