Color flow Doppler in the diagnosis of double-chambered right ventricle: a demographic and echocardiographic study

A Case Report of Double-Chambered Right Ventricle Associated with Subaterial Ventricular Septal Defect and Rupture of Right Coronary Sinus Aneurysm

Double-chambered right ventricle (DCRV) is a rare congenital heart disease in which the right ventricle (RV) is divided into two chambers by anomalous muscle bundles. Here, we report a case of DCRV associated with subarterial ventricular septal defect (VSD) and rupture of right coronary sinus aneurysm (RCSA); the patient was diagnosed by echocardiography and later confirmed by surgical operation.

Multimodality cardiac imaging of a double chambered right ventricle with intrapulmonary shunting: a case report

Background

Double chambered right ventricle (DCRV) is a relatively rare congenital heart disease, characterized by the abnormal division of the right ventricle into a high-pressure inlet and low-pressure outlet by anomalous muscle bundles. Extra-cardiac right-to-left shunts may present with clinical symptoms in adulthood and should be sought in patients with previous cavo-pulmonary shunt procedures.

Case presentation

We report a case of DCRV in a 29 year old Caucasian male presenting in adulthood with a right-to-left shunt secondary to venous collaterals, following cavopulmonary anastomosis for congenital pulmonary atresia and hypoplastic right ventricle.

Conclusion

Multimodality cardiac imaging using echocardiography, cardiac CT, cardiac MRI and cardiac catheterization is often required for complete characterization of complex congenital heart anomalies in adulthood.
