Abstract

We show the virtual simulation of the fluoroscopic location of the membranous septum using preprocedural cardiac computed tomographic data sets. Recognizing the risk distance before the procedure can help individualize implantation strategy to reduce the risk of atrioventricular conduction axis damage during transcatheter aortic valve replacement. (Level of Difficulty: Advanced.).

Keywords: atrioventricular conduction axis; computed tomography; membranous septum; transcatheter aortic valve replacement; virtual basal ring.
