While still considered a high-risk procedure, cardiac catheterization during the early postoperative period is being performed more frequently in the current era. Limited data are currently available concerning the acute hemodynamic consequences of these procedures. Therefore, the purpose of this study was to evaluate the safety/efficacy of cardiac catheterization performed within thirty days of congenital heart surgery. We completed a retrospective review of all catheterizations within 30 days of congenital heart surgery. Procedures were performed due to failure to progress or hemodynamic deterioration. There were 1873 congenital heart surgeries during the study period. One hundred and three (6.2%) patients with a median age of 124 days underwent catheterization. Sixty-three cases received interventions, and forty patients underwent diagnostic catheterization. Early cardiac catheterization did not show a significant immediate change in the hemodynamics or inotrope score. Survival for patients undergoing diagnostic Cath (81%) did not differ significantly from the intervention group (89%). Although cardiac catheterization was performed on patients at the highest risk for death in the postoperative period, catheter intervention did not increase the risk of death. Those patients undergoing catheter intervention did not seem to experience major adverse events but achieved mild improvement in tissue perfusion.
