✦ Synopsis
We studied the first 202 patients with rheumatic mitral stenosis (MS) who underwent percutaneous balloon mitral valvuloplasty (PBMV) with the Inoue balloon catheter for a follow-up (FU) period of 5-11 years. Pre-and post-PBMV and at FU, the mean left atrial pressure was 21.3 ؎ 7.4, 10.2 ؎ 5.6, and 11.2 ؎ 4.1 mm Hg; mean diastolic mitral gradient was 18.4 ؎ 7.3, 2.9 ؎ 3.2, and 5.1 ؎ 4.3 mm Hg; and mitral valve area was 1.0 ؎ 0.3, 2.1 ؎ 0.6, and 1.7 ؎ 0.5 cm 2 . Functional status improved from New York Heart Association (NYHA) class IV in 3, class III in 119, and class II in 80 pre-PBMV to class I in 163, class II in 37, and class III in 2 post-PBMV, and was class I in 146, class II in 39, and class III in 17 patients at FU. In the 17 patients with NYHA class III at FU, mitral restenosis was the culprit; 4 underwent repeat PBMV, 12 had mitral valve replacement for severe mitral calcification and subvalvular fusion, and 1 refused further intervention. Thus PBMV using the Inoue balloon catheter is an effective method of relieving MS with excellent long-term results in patients without severe mitral calcification and subvalvular fusion. Cathet.
