Prihadi EA, et al. - The authors evaluated the feasibility, accuracy, and reproducibility of automated 3D echocardiographic software (AVN) measurements in transcatheter aortic valve replacement (TAVR) candidates by performing a comparison with multi–detector row computed tomography (MDCT). They concluded that new automated 3D transesophageal echocardiographic software provided accurate modeling and reproducible quantification of aortic annular and root dimensions with high feasibility. An excellent relationship between measurements with AVN and MDCT and agreement in prosthesis sizing recommended the use of AVN in clinical practice as a potential alternative to MDCT before TAVR.
