Hemodynamic evaluation of heart valve prostheses paradigm shift for transcatheter valves?

l p he treatment of aortic valve disease is undergoing rapid hanges. In addition to conventional valve replacement that as evolved as the gold standard over several decades, ranscatheter techniques have been introduced into clinical ractice. Whereas the conventional approach offers very recise and safe suturing of standard valves with low failure ates and excellent proven long-term outcomes, transcathter techniques allow for off-pump beating-heart valve mplantations that can even be performed without general nesthesia in some patients. To determine the clinical benefits f transcatheter valve implantation in comparison with conentional aortic valve surgery, randomized trials are required.
