PHAN V. NGUYEN.
HEART INSTITUTE, HO CHI MINH, Viet Nam.

OBJECTIVE:Severe leaflet retraction was presented in 15% of rheumatic MR .Leaflet extension with autologous pericardial patch was found a good solution to repair this lesion . METHODS: Measurement the anterior leaflet diameter by TEE . If this diameter was less than 26mm . We need to extend the valve with pericardial patch . RESULTS: From 1992 to 2008 , 221 patients with rheumatic MR underwent leaflet augmentation technique at the Heart Institute - Viet Nam . Age ranged from 6 to 54 years old ,85% anterior leaflet extension and 15% posterior leaflet extension . The surface area of leaflet was increased up to 30 - 40% after extension . We can use the ring al least N.26 after extension . Hospital mortality = 2 pts (1.2%) Mean time of follow-up 108 +_ 2.61 months . Echo control at the last examination : 77% excellent , 20 % moderate MR and 3% severe MR Actuarial survival rate at 10 years = 95.4 +_ 0.8% Non-fatal complcation : Endocarditis (4) , patch dehiscence (2) , leaflet retraction (4) , calcified patch (18) . 10 years free from re-operation = 96.4 +_ 3.6% CONCLUSIONS: This is a safe technique , increase feasibility of repair for rheumatic MR .
