[The transatrial-transpulmonary correction of tetralogy of Fallot].
The technical problems and morbi-mortality related with operations in two stages repair of tetralogy of Fallot (T.F) had lead several groups to correct it in early stages. We present 19 infants with T.F operated between July of 1988 and August 1992, 11 males and 8 females whose ages ranged from eleven months to eleven years. Without previous surgery, the preoperative catheterization show 71.4 mm Hg of trans-infundibular gradient. The obstruction was relieved through right atriotomy in combination with one pulmonary arteriotomy from above. The ventricular septal defect was closed. One patient with severe pulmonary hypertension died. The rest show gradient less than 21 mm Hg, and NYHA I-II without medicine (23.1 months of follow up). The echocardiography shows that pulmonary regurgitation was present in 54.9% but only 3 cases was it graded as moderated and none was it severe. Transatrial transpulmonary repairs avoids the depression of ventricular performance caused by transannular corrections with ventriculotomy. Preserves muscular contractions and thus reduces the propensity to right ventricular failure. It can be performed to many patients included anomalous origin of the left anterior descending coronary artery.
