Literature was reviewed regarding the outcomes of ventricular-demand leadless pacemaker therapy for heart block after transcatheter aortic valve replacement (tavr).Medtronic evolut (n = 13) and non-medtronic sapien (n = 26) transcatheter valve types were implanted in the study population.After tavr, all 39 patients included in the study underwent permanent pacemaker implantation for new high-grade (complete or advanced) atrioventricular block.The authors observed 12 deaths during the two-year follow-up.No evidence was presented to suggest that a medtronic valve or its function contributed to any of the deaths.Other adverse events consisted of mitral regurgitation development, tricuspid regurgitation development, reduced left ventricular ejection fraction, prosthesis-patient mismatch, paravalvular regurgitation (moderate to severe), rehospitalization for heart failure, and new atrial fibrillation.No additional adverse events related to tavr were noted.
