Dear Sir,
My colleagues and I thank Dr Fesslova for her interest in our study. We have re-evaluated our data to try to answer her question, and we also commend her on the recent publication in the Italian Journal of Paediatrics. Only two of our 21 patients with innocent murmurs have mitral regurgitation of moderate severity. All the others have mild regurgitation. In one of the two patients initially with moderate regurgitation, the lesion has regressed and returned to within normal limits. The other patient still has moderate regurgitation and continues to be followed up. We agree with Dr Fesslova that Doppler echocardiography is an essential technique for the recognition of mild lesions.
