Abstract
FLORES FLORES, Jesús et al. Mitral percutaneous valvuloplasty with Inoue Balloon: Long-term results at the National Medical Center 20 de Noviembre ISSSTE, Mexico. Arch. Cardiol. Méx. [online]. 2003, vol.73, n.1, pp.18-23. ISSN 1665-1731.
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. (Arch Cardiol Mex 2003; 73:18-23).
