Abstract
Purpose of Review
The aim of this article is to review the role of imaging in pre-procedural assessment prior to transcatheter aortic valve replacement (TAVR)—with a focus on relevant anatomic findings apart from the size of the aortic annulus.
Recent Findings
Pre-procedure imaging prior to TAVR heavily emphasizes assessment of the aortic annulus for appropriate valve sizing, with computed tomography angiography (CTA) emerging as the test of choice due to its ability to assess not only the aortic annulus but also the thoracoabdominal aorta and peripheral vasculature. Some patients with underlying kidney disease may be at increased risk of renal dysfunction following contrast-enhanced CTA; however, alternate imaging techniques can be performed to mitigate this risk such as magnetic resonance imaging.
Summary
Familiarity with underlying anatomic variability and pathology relevant to TAVR implantation in addition to annulus size, as well as imaging approaches in patients with renal dysfunction, will allow radiologists to better contribute to multidisciplinary discussion for potential TAVR candidates.
