title: Relationship of pulmonary artery size to mortality in patients undergoing the Fontan operation.
abstract: The size of the pulmonary arteries, measured intraoperatively, was correlated with operative mortality in 90 patients who underwent the Fontan operation. There was no significant difference in the cross-sectional area of the right and left pulmonary arteries/body surface area (PA index) between survivors and nonsurvivors. There was no significant difference in mortality rates between patients with a PA index greater than 250 and those with a PA index less than 250 mm2/m2. Survival was observed with cross-sectional area as low as 188 mm2/m2.
