Brief Summary
This randomized controlled trial was designed to analyze flow patterns in the ascending aorta with MRI after either Trileaflet reconstruction of the aortic valve with autologous pericardium (TriRec) or surgical valve replacement with biological prosthesis. The hypothesis is that after TriRec procedure more physiological flow patterns will be observed, compared to biological valve prosthesis.
