RESULTADOS DE LA VALVULOPLASTIA MITRAL PERCUTÁNEA. EXPERIENCIA EN EL INSTITUTO DE CARDIOLOGÍA Y CIRUGÍA CARDIOVASCULAR DE CUBA (1998-2004) / Results of percutaneous mitral valvuloplasty. Experiences at the Cardiology and Cardiovascular Surgery Institute in Cuba (1998-2004)
Abstract
Antecedents and Objectives: The percutaneous mitral valvuloplasty is the procedure of choice in patients with mitral stenosis and an adequate valvular anatomy. The cases treated in Cuba were few until 1998, and the first ones were carried out by foreign medical professionals. This article aims at showing the results of the development of this technique in Cuba. Method: A total of 110 consecutive percutaneous mitral valvuloplasties were carried out in 107 patients (three of them were repeated due to restenosis) at the Cuban Cardiology and Cardiovascular Surgery Institute, between June 17th 1998 and June 30th 2004 (106 using the Inoue method and 4 by Multi-track). The average evolution time was 24.6 months (72 maximum and 1,93 minimum). Results: Before the procedure, 94.54 percent of the patients were within the functional classification III and IV of the NYHA; after the procedure 96,36 percent were within functional classification I and II. Using the Wilkins score ≤ 8, average areas of 2,18 cm2 were obtained; and between 9 and 12, areas of 1,81 cm2. The initial success of the procedure was 96,36 percent, and without complications 92,72 percent. Mortality was 0,9 percent, survival 100 percent, and 91,74 percent of the patients were free from complications. As an adverse event in the follow-up it was determined a mitral reestenosis in 5 patients (4,54 %). The average stay in hospital was of 1,36 days. The savings concerning hospitalization was of $ 4136775.39. Conclusions: Percutaneous mitral valvuloplasty is a safe and effective method in patients with mitral stenosis; its results remain in the sort, medium or long run.
