Insights
Pediatric cardiac catheterization complications were analyzed in 1000 patients. Newborns had higher mortality (9.3%), but this decreased with anesthesia and ventilation, suggesting improved outcomes for pediatric cardiac interventions.
Area of Science:
- Pediatric Cardiology
- Interventional Cardiology
Background:
- Cardiac catheterization is a common diagnostic and therapeutic procedure in pediatric patients.
- Complications can significantly impact patient outcomes, especially in newborns.
Purpose of the Study:
- To prospectively record and analyze complications associated with cardiac catheterization in a cohort of 1000 pediatric patients.
- To identify risk factors and trends in complications, particularly mortality and arterial/venous issues.
Main Methods:
- Prospective recording of complications in 1000 pediatric patients undergoing cardiac catheterization.
- Analysis of mortality rates, arterial complications, and venous thrombosis.
- Comparison of outcomes between the first and second 500 patients.
Main Results:
- Overall mortality was 1.8%; newborns had a 9.3% mortality rate, primarily due to cardiac failure, hypoxia, and arrhythmias.
- Arterial complications occurred in 10% of patients.
- Late venous thrombosis was a serious issue, particularly in cyanotic malformations.
Conclusions:
- Mortality in newborns undergoing cardiac catheterization appears to decrease with anesthesia and ventilation.
- Increasing operator experience and improved non-invasive diagnostics may also contribute to better outcomes.
- Arterial and venous complications remain significant concerns requiring further attention.
Abstract:
Complications of cardiac catheterization of 1 000 subsequent investigations of pediatric patients were prospectively recorded. 18.2% of all patients presented in the newborn period with usual distribution of cardiac malformations of this age group. Total mortality was 1.8% within the first 24 hours. Newborn babies who were commonly hypoxic and in cardiac failure at the time of catheterization had a mortality of 9.3%. Causes of death were cardiac failure, hypoxia and severe arrhythmias. Comparing the first and second five hundred patients, mortality in the newborn seems to decrease with anaesthesia and ventilation of the patient. Increasing experience of the investigators and exclusion of non-operable malformations from catheterization by non invasive methods might also be responsible for this effect. The rate of arterial complications is 10% and high in our patients. Late venous thrombosis of the iliac veins and inferior vena cava in cyanotic malformations is one of the most serious problems. Apart from balloon atrial septostomy, the use of flow-guided balloon catheters in previous catheterizations could be responsible.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
