title: [Arterial switch operation for simple transposition of the great arteries in infancy].
abstract: Five infants (22-42 days of life) underwent arterial switch operation for simple transposition of the great arteries under deep hypothermic cardio-pulmonary bypass. Three babies required prostaglandin E1 infusion to keep ductus arteriosus opened widely before surgery. Balloon atrioseptostomy was necessary in 0-10 days of life in all babies because of poor condition. Left to right ventricular peak pressure ratio ranged from 0.75 to 0.86, preoperatively. Four of the five survived the operation, and one died of coronary insufficiency because of kinking of the implanted coronary artery. Hypothermic circulatory arrest was used in three (38-41 minutes). Aortic cross clamp time was 70-100 minutes, and cold crystalloid cardioplegia was given only one time just after aortic clamp in 3 babies. Single dose of cardioplegia protected left ventricular muscle well in babies with transposition of the great arteries as same as multiple dose method used in those with ventricular septal defect.
