Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (P-MAIVF) is a rare but potentially fatal entity. Early diagnosis and surgical treatment are particularly important to decrease risk of mortality. The purpose of this study was to explore the echocardiographic characteristics and outcome of P-MAIVF and to evaluate the potential application of three-dimensional (3D) echocardiography in the evaluation of P-MAIVF. Clinical and echocardiographic characteristics were retrospectively evaluated in 9 patients with P-MAIVF, 5 of them assessed by 3D echocardiography. P-MAIVF was identified on echocardiography and located in the posterior aspect of the aortic root, expanding in systole and collapsing in diastole. Of the 9 cases examined, 8 were associated with endocarditis and 1 was caused by radio frequency catheter ablation of atrial fibrillation. Five cases were associated with bicuspid aortic valve, and rupture of P-MAIVF was identified in 3 patients. The morphology of P-MAIVF was clearly demonstrated on 3D echocardiography in 5 cases. In conclusion, echocardiography provides a useful tool in the diagnosis of P-MAIVF. Color Doppler flow imaging can ease identification of the ostium in cases of ruptured pseudoaneurysms. Three-dimensional echocardiography shows the relationship between P-MAIVF and the adjacent anatomic structures.
