A Fontan procedure has been performed on 29 patients for tricuspid valvular
atresia. The age range was 8 months to 33 years (median 10 years), the
pulmonary vascular resistance ranged from 1.8-6.1 units . m2 (mean 3.3
units . m2), and the mean pulmonary arterial pressure ranged from 13-45 mm
Hg (mean 21 mm Hg). Twenty-nine previous operations had been performed in
23 patients. Fourteen other associated cardiopulmonary anomalies were
present in 12 patients. There were four hospital deaths (13.8%), all in
patients with complicating features. Among the last 22 consecutive patients
who have undergone operation, one died (4.5%). Complete atrioventricular
block necessitated pacemaker implantation in one patient. No late deaths
occurred. Of the 19 patients followed 3 months or more from the time of
operation, eight have no restriction of exercise capacity, nine have only
mild restriction, and two have a poor result. The Fontan approach to
tricuspid atresia has several theoretical advantages over previously used
shunts or pulmonary artery banding, the operative mortality in patients who
have suitable anatomy and hemodynamics is low, and the results have been
good.
