Reconstructive surgery for congenital mitral
regurgitation (MR) still has some technical
difficulties, because of the valve is small, fragile
tissue, limited valve exposure and not many available
techniques used for the children. This study was
carried out to evaluate the longterm results of
reconstructive techniques for congenital MR with
Carpentier's techniques at Heart Institute - Ho chi
Minh city.
- Methods: From 01/1992 to 12/2007, we have
repaired 57 children with severe MR at Heart Institute
- Ho chi Minh city. Mean age was 7,9 +_ 4,1 (from 1
to 15 years old, 36,8% of patients was less than 6
years old). Severe MR was presented in 100% of
patients. According to Carpentier's classification, 10
patients was type I (normal leaflet motion), 45
patients was type II (leaflet prolapse) and 2 patients
was type III (restricted leaflet motion). 100% of
patients had pulmonary artery hypertension, 2 patients
had atrial fibrillation (AF). *
- Results: mean time of follow-up = 75,5 ± 51,1
months (from 1 to 181 months). All patients have
good results with significant decrease of pulmonary
artery pressure, 2 patients with AF reversed to sinus
rhythm after surgery. Significant decrease of end
diastolic of left ventricle. 2 deaths during 30 days
post-operative. No late death, no haemorrage, no
reoperation, no valve related complications.
- Conclusion: Reconstructive surgery was
available for congenital MR with good longterm
results, low mortality and low complication post
operative
