CTICasesParavalvular pseudoaneurysm post-TAVR
Imaging findings
Gated CT scan of a 69-year-old male shows a paravalvular pseudoaneurysm arising from the left ventricular outflow tract inferior to the left coronary cusp, mimicking a left atrial appendage.
Key takeaways
Paravalvular pseudoaneurysms can develop post-TAVR due to infective endocarditis or mechanical injury to the aortic annulus. They can track into the subvalvular space and mimic normal structures like the left atrial appendage.
