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.
