 Transcatheter aortic valve implantation TAVI is associated to myocardial injury, defined as post-procedural cardiac troponin cTn elevation. Earlier experiences have shown that myocardial damage can be encountered in a percentage of patients that varies from 1.5 to 17, depending on the access route transfemoral and transapical, respectively. The degree of rise in cTn after TAVI emerged as an independent predictor of mortality.
