[Isolated double-chambered right ventricle (DCRV): a case study conducted at the National University Hospital CNHU-HKM in Cotonou, Benin]. / Ventricule droit à double chambre (VDDC) isolé: à propos d'un cas au CNHU, Cotonou, Bénin.

Double-chambered right ventricle (DCRV) is a very rare cardiac defect in which the right ventricle is divided by anomalous muscle bundle into two chambers. It is associated with other malformations in 80-90% of cases. Clinical presentation varies and depends on the extent of the intraventricular obstruction. We here report the case of a 16-year old teenager with isolated DCRV revealed by recurrent syncopes. The diagnosis was made using Doppler echocardiography. The patient underwent successful surgical resection of the abnormal muscle band.
