摘要(Abstract)：
目的:评价经皮间隔心肌消融术(PTSMA)治疗梗阻性肥厚型心肌病(HOCM)的近期疗效及安全性。方法:对我院自2000年7月以来收治的6例HOCM患者行PTSMA术,分别在术前、术后及3个月后行超声心动图,记录室间隔厚度及左室流出道压力阶差(LVOTG)。结果:6例PTSMA手术均获成功,术后自觉症状明显缓解,心功能恢复为Ⅰ~Ⅱ级。LVOTG术前平均(94.0±40.8)mmHg,术后即刻(33.7±18.7)mmHg,术后3个月(32.5±12.9)mmHg,差异有统计学意义(P<0.05)。室间隔厚度术前平均(25.6±7.3)mm,术后1周(19.7±3.8)mm,术后3个月(15.5±4.2)mm,术后3个月与术前比较,差异有统计学意义(P<0.05)。1例发生一过性Ⅲ°房室传导阻滞,2 h后恢复正常,2例发生完全性右束支传导阻滞。结论:PTSMA是HOCM的一种有效治疗方法,近期疗效好,但其远期疗效仍需进一步观察。
