Dear Sir,
Re: Optimal timing of the Ross procedure
I have read with great interest the article published in your journal by Michael Cheung and colleagues.1 Obviously the authors did not read our article,2 even though they mentioned it, when they claimed that “there are no systematic studies in children describing the relationship between functional recovery and preoperative characteristics”.
Our paper was exclusively based on that aspect, giving the left ventricular Z-score guidelines for optimal timing for surgery.
