摘　　要：应用经皮穿刺球囊导管二尖瓣成形术(PBMV)治疗45例风湿性心脏病二尖瓣狭窄(MS)患者,均获成功。其二尖瓣瓣口面积从术前的1.05±0.31cm^2增至术后的2.10±0.51cm^2(P<0.001),二尖瓣跨瓣膜压力阶差从术前的2.6±0.7kPa(19.4±5.2mmHg)降至术后的1.1±0.2kPa(8.0±1.8mmHg)(P<0.001),左心房平均压从术前的3.0±0.9kPa(22.5±7.1mmHg)降至术后的1.4±0.5kPa(10.6±3.4mmHg)(P<0.001),左心房内径72h 内从术前的46.6±5.7mm 降至术后的38.9±5.1mm(P<0.001);患者心功能均明显改善,心前区舒张期杂音消失或明显减弱,且无任何严重并发症,提示该技术系一项非开胸治愈 MS 的可靠方法。Percutaneous balloon mitral valvulop- lasty(PBMV)was performed succes- sfully in 31 patients with mitral valve stenosis,without any serious compli- cation.All patients experienced dec- reases in left ventricle to left atrium gradient from 2.6±0.7kPa(19.4±5.2 mmHg)to 1.1±0.2kPa(8.0±1.8mmHg) (P<0.001),in mean left atrium pres- sure from 3.0±0.9kPa(22.5±7.1mmHg) to 1.4±0.5kPa(10.6±3.4mmHg)(P< 0.001),in left atrium inner diameter from 46.6±5.7 mm to 38.9±5.1 mm within 72 hours(P<0.001)and an in- crease in mitralvalve area from 1.05± 0.31 to 2.10±0.51cm^2(P<0.001).After PBMV,their cardiac function was improved significantly,and the di- astolic murmur was reduced distinctly or diminished.It is suggested that PBMV be safe and effective for this heart disease.
