A total of 292 consecutive patients with severe aortic stenosis undergoing TAVR with a self-expandable valve (CoreValve EvolutRStudy flow chart. As part of the pre-procedural work-up, all patients underwent 12-lead electrocardiograms (ECG), echocardiography, contrast-enhanced computed tomography angiography with ECG-synchronization for assessment of the anatomy and dimension of the aortic valve annulus, iliofemoral arteries, and the measurement of the length of the atrioventricular membranous septum, as described elsewhere [The study was approved by the local ethics committee based on ethical guidelines of the Declaration of Helsinki, and informed consent was obtained in all cases (NCT04128384).
