Patient Identification
We queried radiology reports from 21,336 chest computed tomography (CT) scans performed at a single tertiary care hospital between 2013-2016 on patients ages 50-85 for radiologic diagnosis of thoracic aortic dilatation or thoracic aortic aneurysm. 620 patients were identified with ascending thoracic aortic aneurysms (ATAA) whose records were further reviewed.
