摘    要:目的 总结应用经皮室间隔化学消融(PTSMA)方法治疗肥厚型梗阻性心肌病(HOCM)经验,分析其临床特点及疗效.方法 自2007年1月到2012年5月80例肥厚型梗阻性心肌病患者接受经皮室间隔化学消融术治疗,对临床资料进行回顾性分析,所有患者计算术前及术后经导管测定的左心室流出道压力阶差(LVOTG),术后所有患者均定期复查心电图及超声心动图,随访时间为术后1个月、3个月、6个月、1年,以后每年随访一次,最长为5年,平均随访时间为20个月.结果 消融术前LVOTG平均为(88.7 ±25.4)mm Hg,消融术后6个月、1年、2年平均分别为(26.2±13.6) mm Hg、(26.2±13.4) mmHg、(26.1 ±13.5) mmHg,与术前相比差异有统计学意义(P<0.01);消融术前室间隔(IVS)厚度为(24.2±6.7) mm,消融术后6个月、1年、2年分别为(17.9±3.4)mm、(17.8 ±3.4)mm、(17.8±3.2)mm,与术前相比差异有统计学意义(P<0.01);随访观察1个月到5年,76例患者晕厥、头晕、心绞痛、心悸、气喘等症状消失或较术前改善,3例症状复发,1例术后因反复出现心力衰竭,经心脏超声检查考虑为肥厚型心肌病的扩张型心肌病相,最后随访至2年时死于扩张型心肌病.结论 PTSMA治疗HOCM能够显著降低IVS厚度及LVOTG,改善患者临床症状,无严重并发症出现.这表明PTSMA是一种治疗HOCM的有效方法,其近期疗效可靠.

Abstract:Objective To summarize the experiences of percutaneous transluminal septal myocardial ablation (PTSMA) for hypertrophic obstructive cardiomyopathy and analyze its clinical features and efficacy.Methods From January 2007 to May 2012,80 cases of hypertrophic obstructive cardiomyopathy (HOCM) patients accepted percutaneous transluminal septal ablation and their clinical data were retrospectively analyzed.Left ventricle outflow tract pressure gradient (LVOTG) was measured by catheter before and after ablation for all patients.All the subjects were followed up regularly with a mean time of 20 months.Results LVOTG before ablation and at 6 months,1 year,2 years after ablation were (88.7±25.4) mmHg,(26.2-±13.6) mmHg,(26.2 ± 13.4) mm Hgand (26.1 ± 13.5) mmHg,respectively (all P〈0.01).Interventricular septum (IVS) thickness before ablation and at 6 months,1 year,2 years after ablation were (24.2 ±6.7) mm,(17.9 ±3.4) mm,(17.8 ± 3.4)mm and (17.8 ± 3.2) mm.(all P 〈 0.01).During the follow-up,most of the patients (76 patients) had released symptoms.1 patient died from dilated cardiomyopathy (DCM) at 2 years after PTSMA.Conclusions on PTSMA is an effective method in the treatment of HOCM,and can significantly reduce the thickness of IVS and LVOTG,and improve clinical symptoms of HOCM patients,without serious complications.
Keywords:Cardiomyopathy hypertrophic  Percutaneous transluminal septal myocardial  Ablation
