摘要:
Objectives:To analyze the safety and efficacy of chemical ablation of anhydrous alcohol combined with gelatin sponge for patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods:The clinical data of 7 HOCM patients, who underwent chemical ablation with anhydrous alcohol and gelatin sponge in Fuwai Hospital from May 2017 to December 2017, were analyzed. Results:There were 5 males and 2 females, with a median age of 56 years (range, 43-67 years), the mean interventricular septum thickness was (19.6 ± 4.8) mm, the number of ablated septal branch was 1-2, the amount of used anhydrous alcohol was 1.4 (1.0-2.0) ml, the amount of applied gelatin sponge was 0.5 (0.1-1.3) ml. After procedure, the left ventricular outflow tract pressure was significantly decreased ([31.6 ± 12.6] mmHg vs [86.4 ± 20.7] mmHg, P<0.001), NYHA cardiac function was significantly improved (1.4 ± 0.5 vs 2.7 ± 0.8, P <0.05), no relevant complications occurred. Conclusions:Chemical ablation with anhydrous alcohol and gelatin sponge is safe and effective for patients with hypertrophic obstructive cardiomyopathy.%目的:评价无水酒精联合明胶海绵化学消融治疗肥厚型梗阻性心肌病的安全性和有效性.方法:分析2017-05至2017-12我院7例肥厚型梗阻性心肌病患者,行无水酒精联合明胶海绵化学消融的临床资料.结果:7例患者中男性5例,女性2例,中位年龄56(43~67)岁,最大室间隔厚度(19.6±4.8)mm,消融间隔支1~2支,无水酒精用量为1.4(1.0~2.0)ml,明胶海绵用量0.5(0.1~1.3)ml,术后左心室流出道压差下降显著[(31.6±12.6)mmHg vs (86.4±20.7)mmHg ,1 mmHg=0.133kPa,P<0.001)],纽约心脏协会(NYHA)心功能分级明显改善[(1.4±0.5)级 vs (2.7±0.8)级 ,P<0.05],无相关并发症.结论:肥厚型梗阻性心肌病无水酒精联合明胶海绵化学消融安全、有效.
