Palliative repair of transposition of the great arteries with criss-cross heart: Ventricular septal defect and hypoplastic right (systemic) ventricle

Four cases of palliative Mustard or Senning repair for transposition of the great arteries (VGA) with ventricular septal defect (VSD), hypoplastic right ventricle, and superior-inferior ventricular configuration are presented. The palliative Mustard procedure—a Mustard repair without VSD closure—is usually reserved for patients with pulmonary vascular obstructive disease (PVOD). In such cases, VSD closure would result in left ventricular...
