Imaging findings
CT and echocardiogram show dehiscence of an aortic valve prosthesis. The valve structure is displaced superiorly (floating) into the sinuses of Valsalva, with a large posterior paravalvular leak at the mitral-aortic intervalvular fibrosa.
Key takeaways
Prosthetic valve dehiscence can lead to a 'floating' prosthesis and severe paravalvular leak. The posterior mitral-aortic intervalvular fibrosa is the most common site of dehiscence due to its relative avascularity.
