Thoracic Incidental Findings in Preoperative Computed Tomography Evaluation for Transcatheter Aortic Valve Implantation (TAVI)

摘要

Background: Many older patients with aortic stenosis are excluded from surgical intervention due to multiple comorbidities. For these patients, transcatheter aortic valve implantation (TAVI) is a viable treatment alternative. Cardiothoracic computed tomography (CT) provides detailed anatomic assessment of the aortic root structures for patient selection, preprocedural planning, and intraoperative decision-making; however, nonaortic incidental findings are frequently detected. The prevalence and clinical significance of these findings have not been well described.
