摘要 目的应用超声心动图比较肥厚型梗阻性心肌病(HOCM)室间隔心肌切除术和经皮室间隔化学消融术(PTSMA)的疗效。方法86例HOCM患者中35例采用室间隔切除术治疗(手术组),51例给予PTSMA治疗(消融组)。分别用超声心动图于术前、术后测量HOCM患者的室间隔基底段厚度(IVS)、左心室流出道压力阶差(LOVTG)。同时记录心功能等级并进行并发症比较。结果两组都能明显地降低LVOTG和IVS,手术组LVOTG从术前的(108.9±31.3)mmHg降到术后的(16.3±8.2)mmHg,IVS从术前的(24.6±4.8)mm降到术后的(18.3±3.5)mm;消融组LVOTG从术前的(105.2±29.6)mmHg降到术后的(19.0±7.7)mmHg,IVS从术前的(24.1±4.6)mm降到术后的(18.9±4.5)mm。两组术前与术后比较差异均有统计学意义(均P〈0.05),两组术后比较差异无统计学意义(均P〉0.05);两组心功能均较术前明显提高;术后比较差异无统计学意义(P〉0.05)。手术组易发生左束支传导阻滞和主动脉返反流,消融组易发生右柬支传导阻滞。结论室间隔心肌切除术和PTSMA均能明显降低左心室流出道梗阻,明显提高心功能,但各有利弊。
