Early effects of transcatheter aortic valve implantation and aortic valve replacement on myocardial function and injury: insights from Cardiovascular Magnetic Resonance

Background To assess the early effects on myocardial function, reversible and irreversible myocardial injury of both transcatheter (TAVI) and open aortic valve replacement (AVR) utilizing cardiovascular magnetic resonance (CMR) and biochemistry. Although recent studies have reported on clinical outcomes, there has been a paucity of mechanistic data on the effect of TAVI on ventricular function and irreversible myocardial injury.
