Pseudoaneurysm in the region of space spanning between the mitral valve and aortic valve, the mitral aortic intervalvular fibrosa (MAIVF) is a rare complication and its radiographic recognition is important to guide patient's management. The purpose of this exhibit is: To illustrate the anatomy of the mitral-aortic intervalvular fibrosa  (MAIVF) particularly with MDCT and MRI and the correlation with transeophageal and transthoracic echocardiography. To review the pathophysiology and causative factors in the formation of pseudoaneurysms of MAIVF. To recognize the imaging features of the pseudoaneurysms of the MAIVF and be able to recognize potentially lethal complications including compression of the coronary arteries, tamponade and fistulous tracts.  

1. MDCT and MRI anatomy of the MAIVF 2. Pathophysiology and causative factors in the formation of Pseudoaneurysms of MAIVF, including endocarditis, post cardiac valve surgery, trauma. 3. Illustrated examples with a) MDCT, gated acquisitions, multiplanar reconstructions including cardiac planes. b) Cardiac MRI with contrast c) Supplementation with TTE and TEE images. 4. Mimics and pitfalls 5. Role of Imaging findings that support conservative imaging surveillance or surgical intervention.
