SURGICAL EXPERIENCE WITH DOUBLE CHAMBER RIGHT VENTRICLE PRESENTED WITH RIGHT VENTRICLE OUTFLOW TRACT OBSTRUCTION

Abstract

Objective: To present our surgical experience with double chamber rightventricle pathology.

Methodology: This cross sectional study included retrospective analysisof cardiac surgery database at Chaudhry Pervaiz Elahi Institute ofCardiology Multan from May 2010 to April 2016. This study includedsurgical repair of patients having either right ventricle outflow tract or midcavity obstruction due to muscle bundles leading to DCRV. Cases ofPulmonary Stenosis, Tetralogy of Fallot, Pulmonary Atresia and DoubleOutlet Right Ventricle causing RVOT obstruction were excluded fromstudy.Data was analyzed using MS Excel. Mean and Frequency werecalculated for quantitative and qualitative variables respectively.

Results: Out of twenty-five patients, 36% patients had moderator bandand 64% patients had anomalous muscle bands responsible for DCRVand main presentation was right ventricle outflow tract obstruction (RVOTPG = 85.64 +48.91mmHg). Moreover, 12% of patients had Atrial SeptalDefect and 52% had Ventricular Septal Defect as associated cardiacdefects. Surgical repair results were excellent with no operative mortality.

Conclusion: The main clinical presentation in our Double Chamber RightVentricle patients was right ventricle outflow tract obstruction eithercaused by a moderator band or anomalous muscle bundles. Surgicalrepair of DCRV and associate cardiac defects carry excellent results withlow morbidity.
