Pak Heart J Jan ;52(3):229-34.

Objective: To determine procedure related safety, complications, and failure. Methodology: This cross-sectional analysis of PTMC data obtained from the record of 1003 patients suffering from symptomatic severe rheumatic MS who underwent PTMC from 1994-2010. The study was conducted at Department of Cardiology, Mayo Hospital, Lahore. Data of patients who underwent PTMC was analyzed, including information regarding their age & gender, the success,failure, and complications of the procedure and available hemodynamic or echocardiographic findings. Results: Data of 1003 patients (700 females &303 males, age range 7-77 years)was included, with mean age (in years) of 27.75+-10.82 years. Pre-PTMC mean mitral valve area was 0.80+-0.26. Success was achieved in 946 patients. Posts PTMC mean MVA was 1.83+-0.28cm . PTMC could not be completed or was abandoned in 57 patients who either developed dreadful complications causing instability or had actual procedure related difficulties. Severe MR requiring emergency MVR occurred in 6 patients. Cardiac tamponade and CVA developed in 19 patients and 16 patients respectively. Balloon ruptured in 6 patients. Atrial fibrillation occurred in 27 patients during procedure. Conclusion: Balloon mitral valvuloplasty is a safe procedure for management of patients suffering from moderate to severe mitral stenosis.
