Surgical experience with double chamber right ventricle presented with right ventricle outflow tract obstruction.
Pak Heart J Jan ;50(2):122-6.

Objective: To present our surgical experience with double chamber right ventricle pathology. Methodology: This cross sectional study included retrospective analysis of cardiac surgery database at Chaudhry Pervaiz Elahi Institute of Cardiology Multan from May 2010 to April 2016. This study included surgical repair of patients having either right ventricle outflow tract or mid cavity obstruction due to muscle bundles leading to DCRV. Cases of Pulmonary Stenosis, Tetralogy of Fallot, Pulmonary Atresia and Double Outlet Right Ventricle causing RVOT obstruction were excluded from study. Data was analyzed using MS Excel. Mean and Frequency were calculated for quantitative and qualitative variables respectively. Results: Out of twenty-five patients, 36% patients had moderator band and 64% patients had anomalous muscle bands responsible for DCRV and main presentation was right ventricle outflow tract obstruction (RVOTPG = 85.64 +48.91 mmHg). Moreover, 12% of patients had Atrial Septal Defect and 52% had Ventricular Septal Defect as associated cardiac defects. Surgical repair results were excellent with no operative mortality. Conclusion: The main clinical presentation in our Double Chamber Right Ventricle patients was right ventricle outflow tract obstruction either caused by a moderator band or anomalous muscle bundles. Surgical repair of DCRV and associate cardiac defects carry excellent results with low morbidity.
