| Abstract: | ObjectiveTo describe the CT and MR features of pseudoaneurysms of the mitral-aortic intervalvular fibrosa (PMAIVF).Materials and methodsThis retrospective study included 9 patients with a diagnosis of PMAIVF who had CT or MRI within 3 months of echocardiography. Echocardiography images were reviewed by a cardiologist and CT and MRI images were reviewed by two experienced cardiothoracic radiologists.ResultsRecognizable imaging features of PMAIVFs were communication with the Left ventricular outflow tract, location between the anterior leaflet of the mitral valve and the aortic valve, systolic expansion and diastolic collapse.ConclusionCT and MRI show characteristic appearances of PMAIVFs and are complementary to echocardiography. |
