Aortic Angulation Attenuates Procedural Success Following Self-Expandable But Not Balloon-Expandable TAVR

Abstract Objectives The aim of this study was to evaluate the impact of increased aortic angulation (AA) on acute procedural success following transcatheter aortic valve replacement (TAVR). Background The degree of angulation between the aorta and the heart can make accurate positioning of the biopr...

Zusammenfassung:	Abstract Objectives The aim of this study was to evaluate the impact of increased aortic angulation (AA) on acute procedural success following transcatheter aortic valve replacement (TAVR). Background The degree of angulation between the aorta and the heart can make accurate positioning of the bioprosthesis during TAVR more demanding, particularly in instances of an extremely angulated or horizontal aortic root. Nonetheless, there are limited data on the impact of AA on the acute success of TAVR. Methods We assessed 582 patients who underwent TAVR at our institute and had contrast computed tomography available for AA evaluation. TAVR endpoints, device success, and adverse events were considered according to the Valve Academic Research Consortium-2 definitions. Results The mean angulation of the aorta was 47.3 ± 8.7°. Patients were therefore divided into 2 groups: AA
