Transcatheter aortic valve implantation through a diseased left common carotid artery: Combined approach with endarterectomy and left carotid‐subclavian bypass

Abstract

We report a case of transcatheter aortic valve implantation (TAVI) with the self-expanding Medtronic CoreValve bioprosthesis (Medtronic, Minneapolis, MI) through a diseased left common carotid (LCC) artery. This 81-year-old male patient presented with heart failure due to a severe degenerative aortic valve stenosis. Comorbidities included diabetes, hypertension, and dyslipidemia as well as peripheral and coronary artery disease, resulting in a logistic EuroScore II of 25.9%. Consequently, he was rejected to undergo surgery and a transcatheter approach was planned. Due to severe peripheral vascular disease with iliofemoral lesions, significant calcifications and unfavourable angulations of the innominate artery as well as prior bypass surgery precluding a direct aortic and subclavian approach, none of the established access sites were suitable. Therefore, we considered a left carotid access, which had to be combined with a surgical endarterectomy for treatment of a significant common carotid bifurcation stenosis and left subclavian-LCC permanent tunnel bypass graft. The procedure was successful without cardiac, cerebrovascular, or access complications. This case illustrates a true heart team approach, establishing a unique access for TAVI for patients without regular access options.
