Congenital diverticula of the cardiac ventricle have been reported as arising either from the left ventricle or, rarely from both ventricles. A diverticulum arising from the right ventricle alone is very rare. Double chambered right ventricle
(DCRV) was
first described in 1962 by Lucas et al, and account for 1.5% of congenital heart disease. Right ventricular diverticulum are associated with right ventricle outlet obstructive disease, tetralogy of fallot, double outlet right ventricle, pulmonic
stenosis, ventricular septal defect, left ventricle-right atrium communication, persistant truncus arteriousus. DCRV are freqently associated with ventricular septal defect (80%), pulmonic stenosis(33%), renal anomaly(43%). Treatment consist of
diverticulum and resection septum. We report a case of double chambered right ventricle with congenital right ventricular true diverticulum in 62 years old female patient admitted due the
