A 11 month old child with transposition of the great arteries and a large ventricular septal defect [VSD] underwent repair by VSD closure and arterial switching with translocation of the coronary ostia. Cardiopulmonary bypass was established along with core cooling to between 18 degree C and low flow was employed. By LeCompte maneuver, we avoided the use of a tubular prosthesis in the repair of pulmonary outflow tract. The post-operative course was uneventful.
