Cardiac Catheterization Post Congenital Cardiac Surgery: Analysis of Risk Factors for Mortality and Literature Review. | LitMetric

AI Article Synopsis

  • Diagnostic and interventional cardiac catheterization is crucial for managing congenital heart defects, but poses higher risks in sick children due to complexity and other health issues.
  • Post-surgery, some children may have residual defects needing further intervention; trans-catheter intervention is challenging and requires a skilled, multidisciplinary team.
  • In a study of 35 patients undergoing 43 procedures, five patients did not survive, but deaths were not linked to the procedures; risk factor analysis showed a moderate correlation but was not statistically significant.

Article Abstract

Background Diagnostic and interventional cardiac catheterization plays a significant role in the management of congenital heart defects with acceptable risks. Its role has also evolved in sick children but is associated with higher risks due to technical difficulties and co-morbidity factors. Some of the post-cardiac surgery children who show resistance to conventional management during the early postoperative period usually have residual defects or obstructions. Trans-catheter intervention (TCI) in such high-risk circumstances and relatively sick children is challenging, demands much expertise, and should be backed up by a competent multidisciplinary team. Some cases improve clinically, while others may require surgical or transcatheter re-intervention for a positive outcome. There is minimal data so far regarding the major complications after interventional cardiac catheterization during the immediate postoperative period after cardiac surgery. We analyzed multiple factors, including age, sex, weight, the initial diagnosis, and the time interval between surgery and TCI, to stratify the possible risks for mortality after TCI during the immediate postoperative period after cardiac surgery. Results Thirty-five patients fulfilled the inclusion criteria and underwent 43 interventional procedures. Five patients could not survive. Four had stent angioplasties on natural vasculature and one patient had in synthetic conduit. None of the mortality was related to the procedure. Multivariable risk factor analysis confirmed a moderate positive correlation coefficient (r) of 0.8017 between the variables. Still, it was not statistically significant if compared among subgroups or among the mortality and survival groups. Conclusion Interventional cardiac catheterization in sick children during the immediate postoperative period can be carried out without much-added risks in expert hands and under the supervision of a multi-disciplinary team. Though no conclusions could be drawn, our study adds to the limited existing data that could inspire others to perform such procedures on sick children. Moreover, the trend in our results indicated a large sample size could have identified a possible risk factor for mortality.
