75mmHg) underwent PBMV using standard Inoue technique, and the changes in clinical functional status and echo Doppler pulmonary systolic pressure during follow up were assessed. Results PBMV was successful in 39 patients. Immediately after the procedure, mitral valve area increased from (0.83?0.12)cm 2 to (1.75?0.11)cm 2 ,pulmonary systolic pressure decreased from (85?7)mmHg to (61?13)mmHg (all P
