BackgroundRheumatic cardiac disease is an immunologic phenomenon that may affect any of the heart valves and is by far the most common cause of mitral stenosis.Aim of the workTo evaluate impact of successful percutaneous balloon mitral valvuloplasty on right ventricular function.Subjects and methods30 consecutive patients who underwent balloon mitral valvuloplasty for rheumatic mitral stenosis between September 2010 and July 2011 at Ain Shams University hospital were included.All patients were subjected to transthoracic echo Doppler study, tissue Doppler imaging and TEE for: (A) Assessment of severity of mitral stenosis. (B) Peak myocardial velocities during systole, early and late diastole. (C) Assessment of RV function by measurement of TAPSE and Tie index.ResultsThe study revealed a significant drop in TAPSE (before and 24h after, P 0.008; before and 3ms after, P 0.001) respectively. There was no significant change 24h and 3ms after the procedure (P 0.220) .There was no significant change in IVC flow before and after 24h (P 0.221). There was no significant drop between before and after 3ms (P 0.062). There was no significant change between 24h and 3ms after the procedure (P 0.264). There was a significant drop in Tie index (before and 24h after, P 0.008; before and 3ms after, P 0.009) respectively but no significant drop was found 24h and 3ms after the procedure (P 0.373).ConclusionThe current study showed a significant improvement in both systolic and diastolic functions of RV as observed by different echocardiographic parameters post BMV in patients without organic TV disease
