We report the case of ventricular tachycardia (VT) ablation procedure in a patient with history of surgically repaired double-outlet left ventricle. The electrophysiology procedure revealed a re-entry pattern between the right-ventricle to main-pulmonary-artery conduit and the tricuspid annulus. The re-entrant mechanism was most likely promoted by a fibrous remodeling of this area, related to the surgical repair. This case is the first to describe a re-entry mechanism between fixed anatomical barriers in a repaired right ventricle of a double-outlet left ventricle. A pace mapping technique was used to highlight the VT isthmus.
我们报告了一例经手术修复的双出口左心室患者行室性心动过速（VT）消融术的病例。电生理检查显示右心室至主肺动脉通道和三尖瓣环之间存在折返模式。这种折返机制很可能是由于该区域的纤维重塑所致，与手术修复有关。该病例首次描述了在修复的双出口左心室右心室的固定解剖屏障之间存在折返机制。采用起搏标测技术来突出 VT 峡部。
