Outcomes
In all reporting studies, postoperative mean aortic valvular gradients were less than 15mmHg and postoperative mean aortic valve surface areas were 1.4cm2 or greater. These findings suggest preliminary successful hemodynamic parameters in both sutureless and rapid-deployment valves in BAV patients. The absence of an outer sewing ring on sutureless prostheses may benefit aortic transvalvular gradients by limiting the external surface area.
