Currently available aortic valve prostheses have satisfactory hemodynamic performance during rest, but with exercise they possess different responses. The objective was to compare the hemodynamic response of the stentless porcine bioprosthesis (SP) and the mechanical bileaflet prosthesis (MB) at rest and during peak exercise using dobutamine stress echocardiography (DSE). DSE was used to evaluate the effective orifice area index (EOAI), peak and mean pressure gradients at rest and during… CONTINUE READING
