Abstract:
:The importance of pulmonary artery size and the value of a standardized pulmonary artery index (PAI) in predicting outcome after Fontan's repair have previously been reported and questioned. We retrospectively reviewed 29 patients undergoing modified Fontan repair at The Children's Hospital of Philadelphia to examine the relation between preoperative PAI (determined echocardiographically) and operative mortality. Twenty-four of these 29 patients underwent pulmonary artery augmentation at the time of Fontan repair. PAIs ranged from 48 to 541 mm2/m2. Operative mortality was 21%. PAI ranged from 68 to 233 mm2/m2 in nonsurvivors and from 48 to 541 mm2/m2 in survivors. There was no statistically significant difference in PAI between survivors and nonsurvivors; the lowest PAI associated with survival (48 mm2/m2) was one fourth of the lowest PAI value previously reported. There was a trend, not statistically significant, toward increased survival in those with larger PAIs. We conclude that patients should not be excluded from consideration for Fontan's repair solely on the basis of pulmonary artery size.
