Cor Triatriatum Dexter With Right Ventricular Hypoplasia: Role of Multimodality Imaging in Decision Making

Sruti Rao et al. Echocardiography. .

Abstract

Cor Triatriatum Dexter (CTD) is a rare congenital anomaly involving the systemic venous valves. Failure of regression of the right-sided sinus venosus valve leads to abnormal septation of the right atrium and a variety of right atrial and tricuspid valve obstructive lesions. The presentation can be varied ranging from asymptomatic to persistent neonatal cyanosis. We describe a late diagnosis of CTD in a 10-month-old male with persistent hypoxia despite balloon valvuloplasty for mild pulmonic valve stenosis with a large secundum atrial septal defect and a mildly hypoplastic right ventricle.

Keywords: Cor triatriatum; atrial septal defect; cardiac imaging; pulmonary valve stenosis; right ventricular volume.
