An experimental surgical technique is proposed to increase pulmonary blood flow in tricuspid atresia with normally related great arteries. The method consists of the creation of a ventricular septal defect in the infundibular septum by means of a closed surgical procedure. The expected advantage would be the growth of the right ventricular cavity. This would permit performance of a Fontan's procedure later, using the right atrium and the right ventricle.
Microscopic sections from the hearts of 4 infants showed no damage in the conduction system. When performed in the beating hearts of dogs, the feasibility of the procedure was tested repeatedly without production of rhythm disturbances.
