【摘要】 目的:对重度二尖 瓣狭窄者进行小径经皮二尖瓣球囊扩张术。方法:应用直径<26mm球囊治疗48例二尖瓣口面积为0.62±0.09cm~2的重度二尖瓣狭窄病人。结果:术后病人心功能改善2级以上,左心房舒张内径、二尖瓣口面积、左心房压改善与术前比较有显著或非常显著统计学差异,并发症极少见。其中4例并发轻度二尖瓣关闭不全,1例术后7d死于脑梗塞。结论:小球囊治疗是一项效果好、安全的治疗重度二尖瓣狭窄的办法。更多还原

【Abstract】 Objective Treating with small balloon percutaneous balloon mitrai valvuloplasty (PBMV) in patients with severe mitrai stenosis (MS). Methods Forty eight patients with severe MSlmitral valve area(MVA) (0. 62 ±0. 09) cm2] were treated with small balloon (diameter< 26 mm) PBMV. Results After PBMV all patient heart function recov-ered over 2 degree, left atrial pressure de-creased significantly(P<0. 001), left atrial di-latic diameter decreased significantly(P< 0.005) and MVA increased significantly (P< 0. 001), and accompanied by mild mitrai re-gurgitation (MR) in only 4 patients, one patient died with cerebral obstruction. Conclusions PBMV is an effective and safe method for treating severe MS.更多还原
