目的 :探讨风湿性心脏病 (RHD)伴重度钙化的二尖瓣狭窄 (MS)患者行经皮二尖瓣球囊成形术 (PB MV)的近期疗效及安全性。方法 :对 33例伴重度钙化的MS患者行逐步球囊扩张法PBMV治疗 ,术中监测左房平均压等 ,术前、术后 3个月进行心脏超声心动图检查 ,并对结果进行统计分析。结果 :术后左房压、二尖瓣跨瓣压差显著下降 ;超声心动图示二尖瓣口面积显著扩大 ,心功能显著改善 ,左房内径、二尖瓣跨瓣压差、肺动脉收缩压显著减小 ,左室内径无显著变化。结论 :逐步扩张法PBMV治疗伴重度钙化的MS是一种安全、有效的方法。
Objective: To investigate the short-term efficacy and safety of percutaneous balloon mitral valvuloplasty (PB MV) in rheumatic heart disease (RHD) patients with severe calcified mitral stenosis (MS). Methods: Thirty-three MS patients with severe calcification were treated with progressive balloon dilatation PBMV. Left atrial mean pressure was monitored intraoperatively. Echocardiography was performed preoperatively and 3 months after operation. The results were statistically analyzed . Results: Postoperative left atrial pressure and mitral valve pressure decreased significantly. Echocardiography showed a significant increase of mitral valve area, significant improvement of cardiac function, left atrium diameter, mitral valve pressure, pulmonary artery systolic pressure Significantly reduced left ventricular diameter no significant change. Conclusion: The gradual expansion of PBMV treatment with severe calcification of MS is a safe and effective method.
