Left ventricular rehabilitation in an infant with transposition of the great arteries, intact ventricular septum, pulmonary stenosis and small left ventricle

초록

We report the 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 2 months of age after having a modified Blalock-Taussig shunt at another hospital. We restricted the atrial septal defect with the child on cardiopulmonary bypass. Ten weeks later, the mitral annulus z-score increased to -1.5, and the transpulmonary peak pressure gradient increased to 87 mmHg. Subsequently, we performed the aortic root translocation. The patient is currently an active 4-year-old boy.
