Assessment of aortic valve area on cardiac computed tomography in symptomatic bicuspid aortic stenosis: Utility and differences from Doppler echocardiography.

ABSTRACT:

Background

In this study, we investigate the utility of geometric orifice area (GOA) on cardiac computed tomography (CT) and differences from effective orifice area (EOA) on Doppler echocardiography in patients with bicuspid aortic stenosis (AS).

Methods

A total of 163 patients (age 64 ± 10 years, 56.4% men) with symptomatic bicuspid AS who were referred for surgery and underwent both cardiac CT and echocardiography within 3 months were studied. To calculate the aortic valve area, GOA_CT was measured by multiplanar CT planimetry, and EOA_Echo was calculated by the continuity equation with Doppler echocardiography. The relationships between GOA_CT and EOA_Echo and patient symptom scale, biomarkers, and left ventricular (LV) functional v
