A 14-year old boy was admitted with an anomalous origin of the right coronary artery (RCA) from the left sinus of Valsalva, with an interarterial course of the narrow proximal segment. He underwent coronary ostial augmentation and main pulmonary artery translocation to the left pulmonary artery. In the post-cardiopulmonary bypass (CPB) period, he developed thrombotic occlusion of the RCA resulting in arrhythmia and ventricular dysfunction, requiring extracorporeal life support (ECLS) in the form of extracorporeal membrane oxygenation rather than CPB. After confirming this complication by cardiac catheterization, the right coronary artery territory was revascularized with a pedicled right internal thoracic artery graft. The entire procedure was performed on a beating heart using a stabilizer during ECLS. This strategy may be useful in situations with unstable haemodynamics and a low risk of blood loss.
一名14岁男孩因右冠状动脉(RCA)起源于左冠窦且近端狭窄段走行于动脉间而入院。他接受了冠状动脉开口扩大术以及主肺动脉向左肺动脉移位术。在体外循环(CPB)期间,他出现了右冠状动脉血栓性闭塞,导致心律失常和心室功能障碍,需要以体外膜肺氧合形式的体外生命支持(ECLS)而非CPB。经心导管检查确认这一并发症后,用带蒂右胸廓内动脉移植物对右冠状动脉区域进行了血运重建。整个手术在ECLS期间使用稳定器在跳动的心脏上进行。这种策略在血流动力学不稳定且失血风险低的情况下可能有用。
