    Abstract:
    BACKGROUND: Transaortic transcatheter aortic valve replacement (TAo-TAVR) is an alternative to peripheral or transapical TAVR. The procedural feasibility, safety, and midterm outcomes of TAo-TAVR were investigated in this study. METHODS AND RESULTS: Eighty-four consecutive patients underwent TAo-TAVR from 2011 to 2021. Their median age was 83 years (interquartile range, 80-87 years). The Edwards SAPIEN and Medtronic CoreValve devices were used in 45 (53.6%) and 38 (45.2%) patients, respectively. The surgical approach was a right mini-thoracotomy in 43 patients (51.2%) and partial sternotomy in 4 patients (4.8%). The remaining 37 patients (44.0%) underwent full sternotomy because of concomitant off-pump coronary artery bypass grafting. VARC-3 device success was achieved in 77 patients (91.7%). Valve migration occurred in 3 patients (3.6%) using a first-generation CoreValve device, necessitating implantation of a second valve. No aortic annulus rupture, aortic dissection, or coronary orifice occlusion occurred. Conversion to surgery was required for 1 patient because of uncontrollable bleeding. Only 1 in-hospital death occurred. New pacemaker implantation was required in 6 patients (7.1%). Echocardiography at discharge showed no or trivial paravalvular leak (PVL) in 58 patients (69.0%), mild PVL in 23 (27.4%), and mild to moderate PVL in 2 (2.4%) patients. The 1- and 3-year incidence of cardiovascular death was 1.6% and 4.8%, respectively, with no structural valve deterioration. CONCLUSIONS: TAo-TAVR is feasible and safe with satisfactory midterm outcomes using both currently available devices.
