BALLOON MITRAL VALVOTOMY: IMMEDIATE OUTCOMES, SUCCESS, FAILURE AND COMPLICATIONS

Abstract

Objective: To determine procedure related safety, complications, and failure.

Methodology: This cross-sectional analysis of PTMC data obtained from therecord of 1003 patients suffering from symptomatic severe rheumatic MS whounderwent PTMC from 1994-2010. The study was conducted at Department ofCardiology, Mayo Hospital, Lahore. Data of patients who underwent PTMC wasanalyzed, including information regarding their age & gender, the success,failure, and complications of the procedure and available hemodynamic orechocardiographic 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 meanmitral valve area was 0.80±0.26. Success was achieved in 946 patients. PostsPTMC mean MVA was 1.83±0.28cm . PTMC could not be completed or was 2abandoned in 57 patients who either developed dreadful complications causinginstability or had actual procedure related difficulties. Severe MR requiringemergency MVR occurred in 6 patients. Cardiac tamponade and CVA developedin 19 patients and 16 patients respectively. Balloon ruptured in 6 patients. Atrialfibrillation occurred in 27 patients during procedure.

Conclusion: Balloon mitral valvuloplasty is a safe procedure for management ofpatients suffering from moderate to severe mitral stenosis.
