By Eric Barnes
Aortic valve replacement may be more accurate when measurements are made with CT versus echocardiography, according to a January 24 paper in Academic Radiology. Coronary CT angiography measurements correlated well with 3D echocardiography results by most measures, making CT a suitable replacement for echo in planning transcatheter aortic valve replacement (TAVR) surgery.
