Aortic valve replacement (AVR) for patients with functioning internal mammalian artery (ITA) grafts is technically challenging, and the optimal treatment strategy for these situations remains controversial. Here, we report five cases of AVR with ITA graft using continuous retrograde cardioplegia in addition to moderate hypothermia without the clamping of ITA and discuss the management of these cases.
对于具有功能良好的内乳动脉(ITA)移植物的患者进行主动脉瓣置换(AVR)在技术上具有挑战性,并且针对这些情况的最佳治疗策略仍存在争议。在此,我们报告5例使用连续逆行心脏停搏液并联合中度低温,且不夹闭ITA进行ITA移植物主动脉瓣置换的病例,并讨论这些病例的处理方法。
