Abstract:

Objective To evaluate the application of mitral valvuloplasty to congenital mitral valve regurgitation in children. Methods The surgical indications, procedures, therapeutic effects and follow-up results of 78 children with mitral valve regurgitation undergoing mitral valvuloplasty were analysed. Results The average duration of follow up was 12.6 months (0.5 month to 73 months). Three patients died after operation during hospitalization. Postoperative complications occurred in 15 patients (19.2%). A second operation was performed in 4 patients, including mitral valve replacement (n=3) and redo mitral valvuloplasty (n=1). One patient was re-hospitalised due to heart failure. During the follow up, grades of mitral valve regurgitation were significantly decreased compared to those before operation (P<0.05). Conclusion Mitral valvuloplasty in children may lead to favorable early outcomes, adapt to children's growth, and effectively delay or avoid mitral valve replacement.
