Abstract

The treatment of high-grade symptomatic aortic valve stenosis is currently undergoing innovative changes. Due to the exponentially growing expertise in the field of catheter-based procedures the gold standard, if still existing, is increasingly being called into question. Inspired by these developments conventional surgical valve prostheses are undergoing changes and enhancements so that they can be implanted with shorter operation times in order to improve the outcome of patients. This retrospective study compared a transcatheter-based aortic valve prosthesis with a surgical rapid deployment prosthesis with respect to postoperative hemodynamic characteristics. Transvalvular pressure gradients and the incidence of paravalvular regurgitation were evaluated as important surrogate parameters for the long-term survival of patients. Furthermore, both valve types were analyzed with respect to the hemodynamic profile in an in vitro model using 4D flow magnetic resonance imaging (MRI).
