Surgical Treatment of Stradding Tricuspid Valve Associated with Double Outlet Right Ventricle

Straddling atrioventricular (A-V) valve is a rare congenital anomaly which further complicates the surgical correction of accompanying cardiac pathologies. In November 1987, a 4-year-old boy with the diagnosis of double outlet right ventricle, atrial septal defect, ventricular septal defect, pulmonary stenosis and straddling tricuspid valve was operated in our clinic. Complete correction of the pathology was achieved after repair of the straddling by using papillary muscle transfer technique. At 29 month followup he was in NYHA class 1, and the tricuspid valve proved to be normal echocardiographically.
