[MSB-03] Comparison of Preoperative Multislice Computed Tomography Measurements with Intraoperative Valve Sizes in Sutureless Rapidly Implantable Biological Aortic Heart Valve and Mechanical Aortic Valve Cases

Preoperative multislice computed tomography is valuable for aortic valve replacement. Biological valves show advantages over mechanical valves in terms of shorter cross-clamp and cardiopulmonary bypass times. More importantly, surgeons tend to avoid procedures such as root enlargement with mechanical valves to reduce operative time, opting for smaller valve sizes. Sutureless valves allow for a larger effective orifice area and less anxiety during surgery, with reduced cross-clamp and bypass times.
