Insights
Predictive factors for paediatric interventional catheterisation complications were identified. Technical challenge, critical condition, and operator errors significantly increase risks, while young age does not.
Area of Science:
- Cardiology
- Pediatric Interventional Cardiology
Background:
- Interventional paediatric catheterisation carries significant risks.
- Risk factors for these complications are not well-established.
Purpose of the Study:
- To identify predictive factors for complications during paediatric interventional catheterisation.
Main Methods:
- Prospective analysis of 1,022 interventional procedures over 8 years.
- Evaluation of patient-related (age, weight, gender, condition) and environment-related (operator training, equipment) variables.
- Classification of complications based on severity and outcomes.
Main Results:
- Overall complication rate was 4.1%, with no significant change over time.
- Independent risk factors included technical challenge, critical patient condition, operator in training, operator error, and equipment malfunction.
- Young age was not found to be a risk factor.
Conclusions:
- Patient and environmental factors are associated with increased risk of procedural complications.
- Understanding these risk factors can improve outcomes in paediatric interventional catheterisation.
Objectives:
To identify predictive factors of complications occurring during paediatric interventional catheterisation.
Background:
Interventional paediatric catheterisation is still burdened by a substantial risk. Risk factors, however, have rarely been investigated.
Methods:
We analysed prospectively 1,022 interventional procedures performed over a period of 8 years, excluding 260 procedures for atrial septostomy. We considered several patient-related variables, specifically age, weight, and gender, type of procedure, times required for fluoroscopy and the overall procedure, technical challenge, and the severity of the clinical condition. We also analysed variables linked to the environment, specifically the date of the examination, whether the operator remained in training, the novelty of the material, any breakdown in the installation, and errors made by the operator. We classified complications as those without clinical consequence, those which proved lethal, those requiring cardiopulmonary resuscitation, elective or emergency surgery, hospitalisation in the intensive care unit, and those leading to recatheterisation.
Results:
Our average incidence of complications was 4.1 per cent, which did not change significantly during the period of study. Of the patients, 4 died, 7 needed urgent surgery, 5 elective surgery, 3 hospitalisation in intensive care unit, and 8 recatheterisation. Independent risk factors for complications were technical challenge, critical clinical condition, operator in training, operator error, and breakdown of the installation. Young age was not associated with a higher risk of complications. Patients in whom no cause for complication could be found, either related to their own features or the environment, had a risk of complication of 1.4 per cent (95 per cent confidence intervals from 0.7 to 2.5 per cent).
Conclusions:
Our data show that variables relating either to the patient or the environment of catheterisation are associated with an increased risk of procedural complications. Knowledge of the risk factors can improve the odds of paediatric interventional catheterisation.
