Abstract 9419: Clinical Impact of Incidental Findings Detected on Computed Tomography in Patients Evaluated for Transcatheter Aortic Valve Replacement

Background: Patients with severe aortic stenosis being considered for transcatheter aortic valve replacement (TAVR) undergo aortoiliac computed tomographic angiography (CTA) of the chest/abdomen/pelvis. Despite the increasing number of TAVR procedures worldwide, little is known regarding the clinical significance of non-cardiovascular incidental findings (IFs) on TAVR-CTA scans. Objective: To determine the frequency, clinical significance and impact on survival of non-cardiovascular IFs detected on TAVR-CTA scans. Methods: CTA studies for 424 consecutive patients being evaluated for TAVR were reviewed for non-cardiovascular IFs (62% male, median age 82±8.3 years). The electronic medical record was reviewed to assess for subsequent clinical management and survival. Results: An IF was present in nearly all patients (99%). The mean number of IFs per patient was 5.3 (±2.8; range 0-14). After excluding obviously benign IFs, 67% had at least one potentially pathologic IF (mean 1.1±1.0). Factors associated with ...
