Abstract

Transcatheter aortic valve implantation (TAVI) has emerged as an important treatment option for elderly patients with symptomatic aortic stenosis whose risk is too high or prohibitive for conventional surgery. Despite notable progress during the past decade, continuous efforts directed at further improvement of procedural safety and performance are required, especially considering expanding indications for interventional treatment options among lower-risk populations. One issue that needs to be addressed is myocardial damage, which can frequently be observed after TAVI and has been linked to worse prognosis. Yet, knowledge concerning the underlying mechanisms and clinical impact remains scarce, and further investigation in this field is warranted. In this review, we provide a contemporary summary of the types of myocardial injury associated with TAVI, including access-related injury, mechanical trauma and ischemia, the role of myocardial biomarkers, and the impact on left ventricular function, with emphasis on potential mechanisms and clinical implications.
