This is a retrospective review of eighty-eight patients who underwent anatomic repair of TGA/ LVOTO between 1995 and 2007 at a single institution. The aim of the study is to assess the outcomes of all patients with a diagnosis of D-transposition of the great arteries with left ventricular outflow tract obstruction (TGA/LVOTO) who underwent anatomic repair and to determine the risk factors for progressive LVOTO and reintervention. Patients underwent either arterial switch operation (ASO) alone (n = 35) or with left ventricular outflow tract (LVOT) intervention (n = 20) or underwent a non ASO intervention such as aortic translocation (n = 12) or Rastelli (n = 21). A balloon atrial septostomy was performed in 37% of patients before repair. Twenty-four percent of patients had undergone placement of a modified Blalock-Taussig shunt as an initial palliative procedure before repair. …
