老年患者经皮球囊二尖瓣扩张术的远期疗效

Long-term outcomes in elderly patients after percutaneous ballon mitral valvuloplasty

目的评价老年风湿性心脏病患者经皮球囊二尖瓣扩张术（PBMV）的远期疗效。方法选择成功行PBMV的老年患者145例,随访1～17（7.4±2.5）年,观察远期疗效。结果随访结束时,患者二尖瓣再狭窄率为26.9%。与术前比较,远期随访时患者二尖瓣跨瓣压差[（9.66±2.71）mm Hg（1mm Hg=0.133kPa）vs（17.10±4.59）mm Hg]、肺动脉收缩压和心功能（NYHA）分级显著下降,二尖瓣口面积显著增加[（1.69±0.22）cm2 vs（0.98±0.20）cm2,P〈0.01],无不良事件生存率为69.7%。结论老年患者成功PBMV后,可获得较好的远期疗效。

Objective To assess the long-term outcomes in elderly patients after percutaneous ballon mitral valvuloplasty（PBMV）.Methods 145elderly mitral stenosis patients with their age≥ 60years who underwent PBMV in our hospital,followed up for more than 1years and their follow-up data were analyzed.Results The patients were followed up for 1-17years（mean：7.4± 2.5years）with a restenosis rate of 26.9%.The average transmitral gradient and systolic pulmonary artery pressures were significantly lower,the mitral valve orifice area was obviously larger, and the long-term heart function was significantly better after operation than before operation（P〈0.01）.The adverse event-free survival rate was 69.7%.Conclusion The long-term outcoms are good in elderly patients after PMBV.
