WebResults: We found that the mean mitral valve area (MVA) had significantly increased from 1.12 ± 0.24 to 2.09 ± 0.46 cm 2 (P < 0.001). The mean pressure gradient across the mitral valve reduced from 17.22 ± 5.55 to 8.94 ± 3.75 mmHg (P < 0.001). The procedures were successful in 91% of the patients.
