چکیده
This study reports the clinical follow-up (13 +/- 1 months) of 100 consecutive patients who underwent percutaneous mitral balloon valvotomy (PMV). Echocardiographic (n = 32) and cardiac catheterization (n = 37) data from this group are also included. Patients were divided into two groups by an echocardiographic score. PMV resulted in a good hemodynamic result (post-PMV mitral valve area, greater than or equal to 1.5 cm2) in 88% of patients with a score of 8 or less and 44% of patients with a score of more than 8. Eighty-eight percent of patients with a score of 8 or less (n = 57) were New York Heart Association (NYHA) functional Classes III and IV before PMV; at follow-up, 81% were NYHA Class I and 12% were NYHA Class II. There were no deaths; three patients underwent mitral valve replacement (MVR). Ninety-eight percent of patients with a score of more than 8 (n = 43) were NYHA Classes III and IV before PMV; at follow-up, 58% were NYHA Classes I and II. Seven patients who did not improve and were not surgical candidates died 3.8 +/- 1.2 months after PMV. Nine patients who were surgical candidates underwent elective MVR at 4 +/- 0.9 months after PMV. Repeat cardiac catheterization demonstrated restenosis in only one of 27 patients (4%) with a score of 8 or less. Mitral valve area after PMV was 1.9 +/- 0.1 cm2 and at follow-up was 2 +/- 0.1 cm2 (NS).(ABSTRACT TRUNCATED AT 250 WORDS)

Postoperative Outcomes of Mitral Valve Repair for Mitral Restenosis after Percutaneous Balloon Mitral Valvotomy
BACKGROUND There have been a number of studies on mitral valve replacement and repeated percutaneous mitral balloon valvotomy for mitral valve restenosis after percutaneous mitral balloon valvotomy. However, studies on mitral valve repair for these patients are rare. In this study, we analyzed postoperative outcomes of mitral valve repair for mitral valve restenosis after percutaneous mitral ba...
متن کامل[Percutaneous mitral balloon valvotomy. Long-term outcome and assessment of risk factors for death and major events].
OBJECTIVE To identify the factors that predict death and combined events, (death, new mitral balloon valvotomy, or mitral valve surgery) in long-term follow-up of patients undergoing percutaneous mitral balloon valvotomy. METHODS Follow-up was 49.0+/-31.0 (1 to 122) months. Techniques used were the single-balloon (84.4%), Inoue-balloon (13.8%), and double-balloon techniques (1.7%). RESULTS ...
متن کاملMitral restenosis and mitral regurgitation 1 year after Inoue mitral balloon valvotomy in a population of patients with pliable mitral valve stenosis.
To determine the rate of mitral restenosis and mitral regurgitation increase 1 year after mitral valvotomy using the Inoue balloon catheter, 66 consecutive patients with severe, pliable mitral stenosis had their mitral valve area (MVA) calculated by two-dimensional echocardiography (2DE) and Doppler before, immediately after balloon valvotomy, and at 1-year follow-up. Color Doppler studies were...
متن کاملThe Association between B-type Natriuretic Peptide Family and Successful Percutaneous Transvenous Mitral Commissurotomy: A Systematic Review
B-type natriuretic peptide (BNP) level is known to increase in patients with rheumatic mitral stenosis. In this systematic review, we aimed to discuss the possible association between plasma BNP level and the success rate of percutaneous transvenous mitral commissurotomy. PubMed and Scopus databases were searched systematically, using the following key terms: “B-type natriuretic peptide” OR “BN...
متن کاملFactors influencing immediate results, complications, and short-term follow-up status after Inoue balloon mitral valvotomy: a North American multicenter study.
Clinical trials with the Inoue mitral valvotomy balloon have recently begun in the United States. We assessed the effects of 17 demographic, echocardiographic, procedural, and hemodynamic variables on the immediate results, complications, and short-term follow-up of 200 patients in 15 centers undergoing valvotomy with this device. The study population had a mean age +/- SD of 53 +/- 15 years, a...
