The serious complications of percutaneous balloon mitral valvuloplasty and their management / 中国介入心脏病学杂志

ABSTRACT

Objective To analyze the serious complications of percutaneous balloon mitral valvuloplasty (PBMV). Methods Between October , 1986,and November, 2000, 1200 patients with rheumatic mitral stenosis age 9-66 older underwent PBMV by Inoue Way. 98% of the balloon catheters were self-made and single balloon catheters.Results Operative successful rate was 98.82% . Serious complications occurred in 51 patients or (4.4%), including 4 cases of death (0.33%), 5 acute serious mitral regurgitation (0.42%), 8 acute cardiac tamponade (0.66%), 28 severe arrhythmia (2.3%), 4 acute left ventricular failure and acute pulmonary edema (0.33%), and 8 systemic thromboembolis. The four cases of death included 1 with acute pulmonary edema, 1 with cardiac arrest, and 2 with acute left ventricular failure with low cardiac output. Conclusion The results demonstrate that PBMV is an efifective and reliable procedure in the treatment of rheumatic mitral stenosis, but a marked decreasement in complication rates is attributable to refinement of patient selection criterion, technical advance in procedure, and strictly management of patients.
