[Surgical treatment of trilogy of Fallot in 42 adults]

From 1984 to 1989 corrective operation circulation was performed under extracorporeal in 42 adults with trilogy of Fallot (6.2% of total intracardial operations under direct vision in patients with congenital heart disease in our hospital). The obstruction was relieved by resection of the hypertrophial and sclerotic muscle trabeculae of the Rt. ventricular outflow tract and pulmonary valvotomy and patching with a piece of artificial blood vessel lined internally by auto-pericardium so that a bougie (more than 1.6cm) could be passed through. The Rt. ventricular pressure was reduced satisfactorily (PRV/PLV < 0.75). There was one operative death.
