ObjectivesThis study sought to demonstrate that early cardiac catheterization, whether used solely as a diagnostic modality or for the use of transcatheter interventional techniques, can be used effectively and with an acceptable risk in the post-operative period.BackgroundCardiac catheterization offers important treatment for patients with congenital heart disease. Early post-operative cardiac catheterization is often necessary to diagnose and treat residual anatomic defects. Experience with interventional catheterization to address post-operative concerns is limited.MethodsThis was a retrospective cohort study. The medical and catheterization data of pediatric patients who underwent a cardiac catheterization ≤30 days after congenital heart surgery between November 2004 and July 2013 were reviewed. Patients who underwent right heart catheterization and endomyocardial biopsy after heart transplantation were excluded.ResultsA total of 219 catheterizations (91 interventional procedures, 128 noninterventional catheterizations) were performed on 193 patients. Sixty-five interventions (71.43%) were dilations, either balloon angioplasty or stent implantation. There was no difference in survival to hospital discharge between those who underwent an interventional versus noninterventional catheterization (p = 0.93). One-year post-operative survival was comparable between those who underwent an intervention (66%) versus diagnostic (71%) catheterization (p = 0.58). There was no difference in the incidence of major or minor complications between the interventional and diagnostic catheterization cohorts (p = 0.21).ConclusionsCardiac catheterization, including transcatheter interventions, can be performed safely in the immediate post-operative period after congenital heart surgery.Copyright © 2014 American College of Cardiology Foundation.
