MR imaging of Ebstein's anomaly of the tricuspid valve.

Abstract

Ebstein's anomaly is an uncommon congenital developmental abnormality of the tricuspid valve that has a wide spectrum of pathologic anatomy. With the evolution of various surgical techniques, through assessment of the morphologic features and type of Ebstein's anomaly assumes greater practical importance. Although the diagnosis of Ebstein's anomaly is usually straightforward and is based on echocardiographic findings, there are limitations in defining pathologic anatomy in some cases. The purpose of this essay is to illustrate the MR findings in various types of Ebstein's anomaly.
