Definitive diagnosis of cor triatriatum with common atrium by three-dimensional transesophageal echocardiography in an adult.

We describe an adult patient, in whom three-dimensional transesophageal echocardiography was able to make a definitive diagnosis of cor triatriatum associated with common atrium. The lesion mimicked a classical partial atrio-ventricular septal defect on both transthoracic and transesophageal two-dimensional echocardiography. We found only two cases in the literature describing the existence of cor triatriatum with common atrium, none diagnosed by echocardiography.

An unusual case of cor triatriatum.

Cor triatriatum (CT) is a rare congenital cardiac anomaly. A case is presented of subdivided left atrium, corrected surgically, which can be considered a type of CT not previously reported.

Early diagnosis and follow-up by echocardiography of acquired cor triatriatum after orthotopic heart transplantation.

Acquired cor triatriatum in a heart transplant recipient, secondary to a prominent left atrial suture line and torsion of the atria, was diagnosed immediately after cardiopulmonary bypass by transesophageal echocardiography. The patient was followed with serial echocardiograms and right heart catheterizations, showing resolution of the obstruction.

[Echocardiographic diagnosis of the right tri-atrial heart]. / Diagnóstico ecocardiográfico del corazón triatrial derecho.

In this report we describe the two-dimensional echocardiographic features of a case of cor triatriatum dexter. In this situation the right atrium is divided by a membrane in two chambers. Considering the anatomic characteristics of this case we added a new type in the classical classification proposed by Doucette et al.
