title: Heart team approach for transcatheter aortic valve implantation procedures complicated by coronary artery occlusion.
abstract: 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.
