[Results of anatomical correction of simple transposition of the great vessels in 46 newborn infants].
Between the 4th April 1984 and 6th December 1984, a strategy of anatomical correction of transposition of the great arteries was undertaken in the newborn if three criteria were respected: parental consent, patient's age of less than 15 days and satisfactory left ventricular geometry. We report our results in 47 consecutive cases operated by the same surgeon at an average age of 8.2 +/- 5.3 days. Atrioseptostomy was performed in all cases before surgery, with a ratio of left to right systolic ventricular pressures greater than 0.66 (m = 0.8) and an infusion of prostaglandin E1 was maintained until surgery in 40 cases. The geometry of the left ventricle assessed by echocardiography was considered to be normal in 23 cases, satisfactory in 22 cases and unfavourable in 2 cases. Except for one case with the great vessels situated in the frontal plane in which an atrial correction was decided upon during surgery, all the patients underwent detransposition under cardiopulmonary bypass without cardiac arrest, irrespective of the coronary anatomy. The pulmonary tract was reconstructed by direct anastomosis with a piece of tanned (first 25 cases) or autologous (following 21 cases) pericardium. There were 18 immediate deaths (17%) but only 4 out of 37 after September 1984 (11%); the causes of failure were: 5 technical errors, 1 irreducible postoperative pulmonary hypertension and 2 probable left ventricular failures. The 38 survivors were followed up for an average of 6.8 +/- 5.4 months (range 1 to 21 months; 28 cases were followed up for over 3 months).(ABSTRACT TRUNCATED AT 250 WORDS)
