BACKGROUND AND AIMS OF THE STUDY Turbulences downstream of mechanical aortic valves are known to contribute to most valve-related complications such as thrombosis, embolization or damage to blood components. In vitro studies have demonstrated the impact of the orientation of prostheses on transvalvular energy loss. This study evaluates the influence of valve orientation on turbulences in the supravalvular aorta in pigs. METHODS A rotation device which could carry a Medtronic Hall (MH) or St… CONTINUE READING
