BACKGROUND
The importance of risk stratification for sudden cardiac death (SCD) after septal myectomy for hypertrophic obstructive cardiomyopathy (HOCM) has not been emphasized previously.
METHODS AND RESULTS
We report 2 patients with SCD or ventricular tachycardia (VT) after septal myectomy for HOCM in whom risk factors for SCD were identified following surgical myectomy. One received an implantable cardioverter-defibrillator (ICD), which subsequently provided appropriate discharges for VT. The other delayed ICD implantation and suffered SCD.
CONCLUSION
These cases emphasize the importance of risk stratification for SCD after septal myectomy for HOCM.
背景
此前未强调肥厚性梗阻性心肌病（HOCM）行室间隔心肌切除术后心脏性猝死（SCD）风险分层的重要性。
方法与结果
我们报告2例HOCM行室间隔心肌切除术后发生SCD或室性心动过速（VT）的患者，在手术心肌切除术后确定了SCD的危险因素。其中1例接受了植入式心脏复律除颤器（ICD），随后该装置对VT进行了恰当电击。另1例延迟植入ICD并发生了SCD。
结论
这些病例强调了HOCM行室间隔心肌切除术后SCD风险分层的重要性。
