ABSTRACT

OBJECTIVES: Our objective was to evaluate the indications for postoperative cardiac catheterizations after pediatric cardiac surgeries and their impact on the results.

METHODS: Unplanned cardiac catheterizations performed after congenital heart surgeries and before discharge between January 2013 and July 2019 were reviewed. Hybrid procedures were excluded. Heart defects, disease progression, surgeries, and catheters were categorized. Indications and results have been compiled comprehensively. The results were analyzed.

RESULTS: Cardiac catheterizations were performed on 192 patients (median age 2.3 months, weight 4.2 kg) at median postoperative day 7 (interquartile range, 2-17 days). Patients had malformations of high complexity (79.9%), a high disease severity index (46.4%), a high Aristotle level of surgical complexity (75%) and a catheterization risk score high for the pediatric category of catheterization (61%). Catheterizations confirmed 66% of suspected diagnoses. Confirmed diagnoses were more likely to be hemodynamic abnormalities than anatomic lesions (81.3% > 53.7%, P 40.4%, P

CONCLUSIONS: Postoperative cardiac catheterizations answer anatomical and hemodynamic questions in high-risk patients with complicated outcomes and guide subsequent treatment with satisfactory results.
