Abstract
|
|
|
The Iinvolvement of subaortic structures in the aortic valve endocarditis appears more commonly than previously recognized. These subaortic complications are most commonly located in the mitral-aortic intervalvular fibrosa and may be presented as
abscess, or as pseudoaneurysm with or without perforation. Perforated pseudoaneurysm can lead to the development of communication between the left ventricular outflow tract and various cardiac chambers, most commonly the left atrium. These complications
are related with poor prognosis. Early and precise recognition of these complications is important for optimal treatment. At present, transesophageal echocardiography (TEE) has been validated as the technique of choice. We describe a case of infectious
pseudoaneurysm of mitral-aortic intervalvular fibrosa featuring the connection of the fistulous simultaneously to the left atrium and aorta. In our case, accurate interpretation of TEE imaging revealing the subaortic structures was not so easy due to
interference of both aortic and mitral prosthetic valves. We expect the further development of (Ed-confirming that here you don't intend, “We expect to further develop”) TEE and other imaging modalities to substantially improve the future diagnosis of
these undesirable complications.
