Abstract 19458: Prevalence of Neoplastic and Non-Neoplastic Incidental Findings as Detected by Computed Tomography in Severe Aortic Stenosis: Single Center PARTNER Trial Data

Abstract

Background:In the emerging era of Trans catheter aortic valve replacement (TAVR), CT is important tool for precise screening and procedural outcomes. Non cardiac incidental findings of malignancy are an important clinical concern.

Methods and results: We retrospectively evaluated the findings from 64-slice screening CT scans performed on 318 patients with severe aortic stenosis (AS) prior to evaluation forTAVR. A total of 235 patients received contrast imaging. Detailed analysis of cardiac and non cardiac structures revealed presence of lung cancer in 10 patients (3%) and Bronchogenic carcinoma in 5 patients (2%), breast cancer in 9 patients (3%), 4 patients with colon cancer (1%) and 4 with lymphoma(1%), 2 with prostate cancer and 1 with renal cell carcinoma and multiple myeloma(1%).

Conclusions: CT is important factor in patient selection for TAVR but reporting of non-cardiac findings must be meticulous. There is a significant proportion of patients with the incidental finding of Neoplasia.
