Myocardial Injury After Transaortic Versus Transapical Transcatheter Aortic Valve Replacement

Periprocedural TAVR-related myocardial injury in nontransfemoral candidates was demonstrated in all patients, but the transapical approach was associated with significantly greater myocardial injury compared with the transaortic approach. A higher degree of myocardial injury translated into reduced left ventricular function improvement and lower early and midterm survival rates.
