Pseudoaneurysm Of Mitral-aortic Intervalvular Fibrosa Research Articles

Mitral-aortic intervalvular fibrosa pseudoaneurysm resulting in the displacement of the left main coronary artery after aortic valve replacement

control chest CT scan was taken on the second postoperative day (Figure 2). It was recognized that the bullet had migrated to the left posteroinferior pulmonary artery. Nevertheless, throughout the patient’s hospital stay, no signs of pulmonary embolism or infection could be observed. Pulmonary and laboratory test results were almost normal (aspartate aminotransferase, 33 IU/L; alanine aminotransferase, 20 IU/L; lactate dehydrogenase, 247 IU/L) on the second day. He was discharged 8 days after the emergency operation.

Mitral-aortic Intervalvular Fibrosa Pseudoaneurysm with Dual Fistula that Occurred in Prosthetic Aortic Valve Endocarditis

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.
