Introduction

Data regarding alcohol septal ablation (ASA) in young patients with hypertrophic obstructive cardiomyopathy (HOCM) are scarce. The purpose of our study is to evaluate the safety and efficacy of ASA in patients ≤ 25 years.

Methods and results

All ASAs between 2002 and 2020 at our institution were assigned to a group of patients 14–25 years of age (group 1) and a reference group > 25 years (group 2). 1,264 procedures were analysed in group 2 (58.6 ± 13.5 years) and 41 procedures in group 1 (20.9 ± 3.3 years). The baseline interventricular septal diameter (IVSD) was higher in group 1 (26.0 ± 6.5 mm vs. 21.3 ± 4.4 mm; p < 0.0001). There was no difference in baseline left ventricular outflow tract gradient (LVOTG) (group 1: 54.4 ± 24.4 mmHg; group 2: 52.4 ± 36.6 mmHg; p = n.s.). A previous cardiac device was more often observed in group 1 (31.7% vs. 9.0%; p < 0.0001). Symptoms were improved after 6 months (group 1: mean NYHA class 2.5 at baseline and 1.3 at FU; p < 0.0001; group 2: mean NYHA class 2.7 at baseline and 1.4 at FU; p <0 .0001). IVSD (group 1: 20.3 ± 8.2 mm; group 2: 16.8 ± 5.7 mm; p < 0.0001 for each group compared to baseline) and LVOTG improved during FU (group 1: 25.5 ± 20.0 mmHg; group 2: 22.1 ± 21.7 mmHg; p < 0.0001 for each group). Intrahospital mortality was 0.0% in patients 14–25 years and 0.9% in the reference group. Persistent AV-block was observed in 12.2% of the group 1 and 15.9% of the group 2 patients (p = n.s.).

Conclusion

ASA is safe and effective in HOCM patients 14–25 years of age in experienced centres.

青少年肥厚型梗阻性心肌病酒精中间隔消融术的安全性和有效性

介绍

有关肥厚性梗阻性心肌病 (HOCM) 年轻患者酒精中隔消融 (ASA) 的数据很少。我们研究的目的是评估 ASA 在 ≤ 25 岁患者中的安全性和有效性。

方法和结果

我们机构 2002 年至 2020 年间的所有 ASA 均被分配到一组 14-25 岁的患者(第 1 组)和一个 > 25 岁的参照组(第 2 组)。对第 2 组(58.6 ± 13.5 年)和第 1 组(20.9 ± 3.3 年)中的 41 例手术进行了分析。第 1 组的基线室间隔直径 (IVSD) 较高(26.0 ± 6.5 mm 与 21.3 ± 4.4 mm;p  < 0.0001)。基线左心室流出道梯度 (LVOTG) 没有差异(第 1 组:54.4 ± 24.4 mmHg;第 2 组:52.4 ± 36.6 mmHg;p  = ns)。在第 1 组中更常观察到先前的心脏装置(31.7% 对 9.0%;p  < 0.0001)。6 个月后症状得到改善(第 1 组:基线时平均 NYHA 等级为 2.5,FU 为 1.3;p < 0.0001;第 2 组:基线平均 NYHA 2.7 级,FU 平均 1.4 级;p  <0 .0001)。IVSD(第 1 组:20.3 ± 8.2 毫米;第 2 组:16.8 ± 5.7 毫米; 与基线相比,每组p < 0.0001)和 LVOTG 在 FU 期间有所改善(第 1 组:25.5 ± 20.0 mmHg;第 2 组:22.1 ± 21.7 mmHg; 每组p < 0.0001)。14-25 岁患者的院内死亡率为 0.0%,参考组为 0.9%。在第 1 组患者的 12.2% 和第 2 组患者中观察到持续性 AV 阻滞(p  = ns)。

结论

ASA 在经验丰富的中心对 14-25 岁的 HOCM 患者是安全有效的。
