Computed tomography angiography is not accurate in predicting surgical prosthetic aortic valve implant size.

Background: Multidetector computed tomography is vital in preoperative sizing for transcatheter aortic valve replacement. The purpose of this study is to determine whether preoperative transcatheter aortic valve replacement multidetector computed tomography accurately predicts surgical aortic valve prosthesis size.

Methods: Between July 2012 and July 2017, 102 patients who underwent surgical aortic valve replacement had preoperative aortic valve sizing by multidetector computed tomography.
