摘要
作者对11例严重风湿性二尖瓣狭窄患者行经皮球囊扩张的治疗,结果9例成功,有良好疗效,2例未成功。文内对病例选择、操作技术和并发症处理等进行讨论。
Percutaneous mitral commissurotomy(PMC)was performed in 11 patients with severe
rheumatic mitral stenosis.The procedure was discontinued because of technical failure in 2
patients.Effective PMC was achieved in the other 9 patients using one balloon in 5 and
two balloons in 4.Immediately after PMC,there was a significant improvement in mean
left atrial pressure(26±7 to 17±3 mmHg,p<0.001),mean mitral gradient(20±
7 to 10±4mmHg,p<0.001),cardiac output(4.3 to 5.2 L/min,p<0.001)and valve
area(0.95±0.22 to 1.76±0.31 cm^2,p<0.001).No patient died or had major com
plications including cerebral embolism,severe mitral regurgitation or ventricular perforation
during the procedure,however,5 patients developed hypotension after PMC,which reco
vered after infusion of plasma substitute.The study suggests that PMC is a safe and ef
fective treatment for mitral stenosis.
