Mitral Valve Repair for Congenital Mitral Valve Disease: Impact of the Use of a Biodegradable Annuloplasty Ring

Mitral valve repair using the biodegradable ring for congenital mitral valve disease was superior compared with non-ring annuloplasty repair. Excellent survival benefit, freedom from reoperation, and valve failure without significant elevation of transmitral gradients, suggests its important role in young children with smaller annular sizes where standard commercial rings are not available or recommended.
