Abstract
We report a case of successful biventricular repair after left ventricular rehabilitation in an infant with transposition of the great arteries with an intact ventricular septum, pulmonary stenosis, a large atrial septal defect, and a borderline-small left ventricle (mitral annulus Z-score: -3.6). This baby presented to us at two months of age after having a modified Blalock-Taussig shunt from another hospital. We restricted the atrial septal defect under cardiopulmonary bypass. Ten weeks later, the mitral annulus Z-score increased to - 1.5, and the transpulmonary peak pressure gradient to 87 mmHg. Subsequently, we performed the aortic root translocation. Currently, he is a four-year-old active boy.
