Cor triatriatum dexter associated with atrial septal defect: Management in a complex clinical case

Abstract

The coexistence of an atrial septal defect and a prominent eustachian valve is a rare congenital anomaly, rarely reported in literature. Differentiation between a giant eustachian valve and cor triatriatum dexter can be difficult. A case of a large atrial septal defect associated with cor triatriatum dexter diagnosed by echocardiography in an asymptomatic woman is reported. A watchful waiting strategy was adopted.

Keywords: atrial septal defect; cardiac magnetic resonance imaging; cor triatriatum dexter; echocardiography; prominent eustachian valve.
