ABSTRACT

Balloon mitral valvuloplasty has, over the last 15 years, become an established interventional procedure for patients with pliable non-calcified mitral stenosis. In this article we describe the long-term outcome of 100 patients from our hospital (National Medical Center "20 de Noviembre" ISSSTE, Mexico City), who were treated with this procedure. Average follow-up was 38.72±22.4 months. The procedure was successful in 83.3% of the patients . After the procedure, the average valvular area changed from 0.95±0.16 to 1.62±0.24 cm2 (P < 0.001) and, at the end of the follow-up time, it was 1.57 ± 0.29. The trans-valvular mean gradient changed from 8.80±3.67 mm Hg to 4.74±1.90 mmHg (P <0.001). Complications occurred in 7.0% of the patients, the most important one being acute mitral insufficiency due to valvular rupture. No deaths occurred. Conclusions: Balloon valvuloplasty is an effective method in patients with Wilkins score of 8 or less, with minimal risk of complications, and long lasting results. At the end of the follow-up time, patients were in NYAH functional class I.
