We studied the atrial morphology in 110 hearts removed at autopsy from patients with tricuspid atresia. Ten of the patients had had a Fontan operation. We compared the findings in these hearts with those in 30 normal hearts. Prominent eustachian valves were common (40%). The tricuspid "dimple," present in 33 of 100 specimens, denoted the membranous atrioventricular septum and was never related to the right ventricle. Most interatrial communications (85/100) were nonobstructive. A minority of patients with obstructive interatrial communications (13/100 = small, 2/100 = severely obstructive) would be expected to benefit from balloon atrial septostomy early in life. Right atrial hypertrophy was greatest in specimens with restrictive interatrial communications (severely obstructive = 3.2 +/- 0.3 mm, small = 2.1 +/- 0.6 mm) and in those that had been subjected to a Fontan operation (3.2 +/- 0.7 mm), but thickness was also increased in hearts with nonobstructive interatrial communications (1.6 +/- 0.5 mm) compared with normal hearts (1.1 +/- 0.2 mm; p less than 0.001 versus all groups). Of the patients in the series, 11 of 100 had left juxtaposition of the atrial appendages, which may have important implications for the Fontan operation.
