If possible I would like to know more about the use of ACE inhibitors for treatment of mitral valve regurgitation. My daughter was born with infracardiac TAPVR that was repaired at 17 days. Due to the repair she has mitral value regurgitation. The surgeons were hopeful it would improve with time but now she is 4 and it is getting worse. We are currently trying and ACEi at a low dose before we consider surgery. Any information you can provide around the safety and efficacy of this treatment would be appreciated. I am also interested in any risks associated with long term use of ACEi in children. If she does need surgery – any questions that we should be asking specifically about mitral valve repair. Thanks for all you do and for sharing your knowledge.
