Alternative approach for angioplasty of stenosed left pulmonary artery following intracardiac repair of tetralogy of Fallot.

A 5-year-old boy with stenosed left pulmonary artery following total correction of tetralogy of Fallot underwent surgical pulmonary arterioplasty through a left anterolateral thoracotomy on a normothermic perfused heart under cardiopulmonary bypass. We found this to be a convenient approach, and recommend it for correction of this lesion in the absence of gross pulmonary regurgitation and right ventricular outflow tract dilatation.
