We report on three out of 270 consecutive patients (1.1%) suffering from coronary artery obstruction or occlusion at the end of transcatheter aortic valve implantation (TAVI). The partial or total obstruction of the coronary artery seen in the post-implantation aortography was accompanied by haemodynamic instability and electrocardiographic changes typical for myocardial ischaemia. Immediate percutaneous coronary intervention with stent implantation was successful in two cases, while in the third case it was not possible to cross the occluded right coronary artery. Emergency coronary artery bypass grafting was performed resulting in uneventful myocardial recovery. All patients were discharged home. These cases highlight the awareness of this rare, life-threatening complication of TAVI, which is in need of a dedicated heart team involved not only in decision-making, but also in the procedure itself.
我们报告了270例连续接受经导管主动脉瓣植入术(TAVI)的患者中的3例(1.1%),这些患者在手术结束时出现冠状动脉阻塞或闭塞。植入后主动脉造影显示的冠状动脉部分或完全阻塞,伴有血流动力学不稳定和心肌缺血典型的心电图变化。两例患者通过立即进行冠状动脉支架植入术成功解决问题,而第三例患者无法穿过闭塞的右冠状动脉。随后进行了紧急冠状动脉搭桥手术,心肌恢复顺利。所有患者均已出院。这些病例凸显了对TAVI这种罕见且危及生命的并发症的认识,处理这一并发症不仅需要专业的心脏团队进行决策,还需要他们参与实际手术操作。
