600.35 Indexed Left Atrial Volume Derived by Computed Tomography and 1-Year Mortality in Patients Undergoing Transcatheter Aortic Valve Replacement

Increased left atrial volume (LAV) is an important marker of poor outcomes in patients with aortic stenosis undergoing transcatheter aortic valve replacement (TAVR). Computed tomography (CT) -based assessment of LAV is a more accurate method than traditional echocardiographic assessment. We
