Ruptured pseudo-aneurysm of the mitral-aortic intervalvular fibrosa - A 3D transesophageal echocardiographic depiction.

Pseudo-aneurysm of the mitral-aortic intervalvular fibrosa (MAIVF) is a rare complication of native or prosthetic valve endocarditis. Good imaging is the key to successful diagnosis of this rare entity. This report describes a pseudo - aneurysm of the MAIVF rupturing into left atrium in a patient with double valve replacement with special reference to 3-dimensional transesophageal echocardiographic imaging. <Learning objective: Transesophageal real-time 3-dimensional echocardiography provides useful information in understanding the anatomy of pseudo-aneurysm of mitral-aortic intervalvular fibrosa and differentiating it from abscess. In our case, it clearly showed a pouch-like, pulsatile structure moving in and out of the left atrium. This can be of immense help in formulating an appropriate surgical or device strategy.>.
