[Fontan surgery in tricuspid atresia. Experience at the National Institute of Cardiology "Ignacio Chávez"].
A retrospective analysis is presented of all patients under 18 years of age with tricuspid atresia and concordant ventriculo-arterial connection who underwent a Fontan procedure in the National Cardiology Institute "Ignacio Chávez", México-City, between January 1989 and December 1995. In this period Fontan procedure was performed in 22 patients with a mean age of 6.52 +/- 1.4 years. 14 of them were females. Thirteen patients had previous palliative procedure. Age of palliation was 10 +/- 12 months with period of 5 +/- 2 years between palliative and Fontan procedure. Overall mortality was 31% (7 patients); with a mortality of 42% between 1989 and 1992, of 22% between 1992 and 1995 and of 17% since 1994 with all 5 patients operated in 1995 surviving. Mean pulmonary pressure was 13.9 +/- 4.15 mmHg, mean pulmonary vascular resistance 1.66 +/- 0.57 U.W/m2, left ventricular end diastolic pressure 7.5 +/- 2.46 mmHg, ejection fraction 58 +/- 11% and Nakata and McGoon indexes 219 +/- 56 mm2/m2 and 2 +/- 0.1 respectively. No significant differences were found survivors and non-survivors, with exception of the left ventricular end-diastolic pressure (p < 0.05). Causes of death were multiple organ failure in 2, ventricular fibrillation in 3 and septic shock in 2.
