Endocarditis abscess of the aortic annulus involving the left ventricular inferior wall and causing a moderate aortic systolic obstruction: diagnosis by transthoracic and transesophageal echocardiography.

Abscesses are an important and potentially devastating complication of aortic valve endocarditis. The extension of the infectious process from the aortic valve to surrounding tissue can occur in different directions. This case report describes a 28-year-old man in whom the abscess of the aortic annulus was very large, causing a moderate aortic systolic obstruction, and also involved the left ventricular inferior wall. The diagnosis was provided by a combination of TTE and TEE examination and was confirmed by cardiac surgery.
