Background: Percutaneous transvenous mitral commissurotomy (PTMC) can increase mitral valve areas and reduce mitral valve gradients in selected patients with mitral stenosis. The PTMC Registry was organized in our institution to address concerns regarding current clinical and procedural outcome.

Methods and Results: This study reports the immediate outcome of patients who underwent percutaneous mitral balloon commissurotomy at the Philippine Heart Center from January 1999 to December 2003. The study group consisted of 202 out of 220 cases of severe mitral stenosis in whom 2D echocardiographic and/or Doppler examination were obtained prior to valvotomy and immediately after the balloon dilatation. There were 175 women (84%), 27 men (13%) with mean age of 37±SD11.56. The most common symptoms were shortness of breath (93%) and easy fatigability (92%). The average Wilkins score was 7.6. Immediately after balloon dilatation significant decreases in mitral valve area, mitral valve gradient, pulmonary artery pressure, and LA and RV dimensions were noted. Procedure successs was noted in 77% of patients. The most common morbidity was the presence of moderate or severe mitral regurgitation which was present in 24 (12%). The mortality rate was 4 (2%), while the combined morbidity and mortality rate was noted in 47 (23%) of cases.

Conclusions: Percutaneous Transvenous Mitral Commissurotomy as practiced in a our institution, produced significant short-term hemodynamic and clinical improvements. PTMC can be considered an effective treatment option in selected patients with symptomatic mitral stenosis.
