摘要(Abstract)：
本文对22例重度二尖瓣狭窄患者进行PBMV治疗.采用改良Inoue法8例,成功6例,应用我们设计的球囊负压操作法14例,全部成功,总成功率91%(20/22).血流动力学显著改善;左心房平均压由术前的3.11±0.82下降至0.91±0.81kPa(P <0.01),肺动脉平均任由4.32±1.52下降至2.78士1.48kPa(P<0.05),二尖瓣跨瓣压差由术前2.35士0.66下降至0.27土0.65kPa(P<0.01),二尖瓣口面积由术前0.69士0.11增加到1.73士0.47cm~2(P<0.01),心功能均明显改善.本组结果显示;采用球囊负压操作法可缩短手术操作时间,减少术中并发症,提高手术成功率.PBMV不仅适用于轻～中度二尖瓣狭窄的患者,亦适用于部分重度MS的患者,且后者较前者疗效更满意.
