Double-chambered right ventricle (DCRV) is a cardiac disease of the right ventricular outflow tract obstruction characterized by anomalous muscle bundles that divide the right ventricle into two chambers. It may be also develop over time as an acquired lesion in patients with an abnormally short distance between the moderator band and the pulmonary valve. This report highlights the case of a man with double-chambered right ventricle after ventricular septal defect operation, who presented with syncope J MEDICINE JAN 2020; 21 (1) : 65-66

Abstract 21 year old male admitted with progressive dyspnea. Transthoracic echocardiogram(TTE) showed membranous type ventricular septal defect(VSD).Additionally there was an evident turbulence and nearly 120mm Hg (5.5m/s maximal velocity) gradient in the mid region of right ventricle(RV) a muscle bundle was restricting the flow. Double chamber right ventricle(DCRV) and VSD have been confirmed also with right heart catheterisation.Measured RV pressures were 90/0/5 mmHg and pulmonary artery pressures were 17/4(mean:8mmHg).Qp/Qs was 1.3. Cardiac magnetic resonance imaging (CMRİ) excluded other congenital defects like atrial septal defect,abnormal pulmonary venous return or aortic coarctation. Cardiac BT also clearly showed the hypertrophied muscular bundle which is close to the apex; was dividing the right ventricle cavity into two parts. Patient has been referred for surgery.On follow up, patient was doing well and TTE nicely showed a clear decrease of gradient as measured maximal velocity was 2m/s and no residual shunt of VSD. Control CMRİ also showed good RV function with a mild residual muscle structure. Our case was a nice example of VSD without pulmonary hypertension because of restricted blood flow of pulmonary artery by a muscle bundle. If VSD is presented with a restricted RV outflow ; instead of a dilated RV chamber as been expected; a concomitant DCRV should be kept in mind. Abstract P1726 Figure. video 1

Double-chambered right ventricle (DCRV) is a rare congenital heart disorder involving 2 different right ventricle (RV) pressure compartments that is often associated with ventricular septal defect (VSD). Usually, the obstruction is caused by an anomalous muscle bundle crossing the RV from the interventricular septum to the RV free wall. We are reporting a case of double-chambered right ventricle associated with ventricular septal defect and congenital absence of the pulmonary valve, a rare form of congenital infundibular pulmonary stenosis. In addition to ventricular septal defect, our patient had congenital absence of the pulmonary valve, which is very unusual and has never been reported to our knowledge.
