Mitral Regurgitation (MR) is frequent finding in patient (Pt.) with Aortic stenosis (AS). The study objective is to know the predictor that influences the change in degree of MR severity post Transcatheter Aortic Valve Implantation (TAVI).
Between April 2009 - January 2012, 50 consecutive patients with Aortic Stenosis underwent (TAVI) procedure with Edward-Sapien Valve in PSCC. MR assessed by visual mapping flow.
They were divided into two groups G1 (MR improved after TAVI) G2 (MR did not improved after TAVI).

Degree of MR Improvement achieved in 56% patient. The predictor factor that influence the reduction of severity of MR Post TAVI are a) Hypertension b) change in the degree of Pulmonary Artery Pressure post TAVI.
However the eteology of MR, change in aortic gradient and change of LV function post TAVI were not significant predictor.
