Abstract:
Percutaneous balloon mitral valvulotomy (PBMV) with the Inoue-balloon is a proven therapy in young patients with mitral stenosis. In this study, we investigated primary results in PBMV of elderly patients. In 383 patients with mitral stenosis PBMV was done with the Inoue-balloon. We compared primary success rates and short-term follow-up of 287 (74.9%) < 65-year-old patients and 96 (26.1%) > or = 65-year-old patients. Elderly patients were more likely to have atrial fibrillation (58% vs. 45%; p < 0.05), tricuspid regurgitation < or = II degrees (58% vs. 45%; p < 0.05), coronary artery disease (16% vs. 6%; p < 0.01), and previous pulmonary edema (42% vs. 30%; p < 0.05). PBMV was successful in 73.9% of the elderly and 84.7% of the younger patients (p < 0.05). Mitral valve gradients could be reduced from 12.5 +/- 11.6 mm Hg to 6.2 +/- 6.8 mmHg (p < 0.001) in elderly patients and from 15.5 +/- 6.9 mm Hg to 7.0 +/- 3.2 mm Hg (p < 0.001) in younger patients. Mitral valve areas increased from 1.0 +/- 0.3 cm2 to 1.6 +/- 0.5 cm2 (p < 0.001) in elderly patients and from 1.0 +/- 0.3 cm2 to 1.7 +/- 0.4 cm2 (p < 0.001) in younger patients. No patient died during the procedure. Two younger patients had emergency surgery because of pericardial tamponade following transseptal puncture. After PBMV elderly patients had more often an increase of mitral regurgitation (47% vs. 35%; p < 0.05) without need of an emergency mitral valve replacement.(ABSTRACT TRUNCATED AT 250 WORDS)
