The Impact of Aortic Arch Morphology on Periprocedural Stroke in Transcatheter Aortic Valve Replacement.

ABSTRACT: Objectives: Stroke after transcatheter aortic valve replacement (TAVR) continues to be one of the most concerning complications. Anatomical variations of the aortic arch may increase the risk of embolic debris entering the brain during transfemoral catheter manipulation. We aimed to analyze the influence of aortic arch morphology on the occurrence of ischemic stroke during TAVR. Methods: We performed a retrospective, 1:2 propensity-matched case-control study to compare patients with and without periprocedural stroke (defined according to the Valve Academic Research Consortium III endpoints) after transfemoral TAVR between June 2007 and September 2022. Multi-slice computed tomography (MSCT) analysis of pre-TAVR aortograms was performed to investigate arch anatomy, configuratio
