Values are mean ± SD or [median, interquartile range (IQR)] or n (%). VARC, valve academic research consortium; TIA, transient ischemic attack; LBBB, left bundle branch block; AV, aortic valve; PVL, paravalvular leak; echo, echocardiography; SE, self-expandable; BE, balloon-expandable; THV, transcatheter heart valve. Post-procedural outcomes (during index hospitalization) were endocarditis and new pacemaker implantation.
