Insights
This study analyzed 109 cases of patent ductus arteriosus (PDA) in children, differentiating between ductus arteriosus persistens (DAP) and ductus arteriosus (DAA). Findings provide data for improved closure or conservation methods for this common congenital heart defect.
Area of Science:
- Pediatric Cardiology
- Congenital Heart Disease
- Interventional Cardiology
Background:
- Patent ductus arteriosus (PDA) is a common congenital heart defect requiring timely diagnosis and management.
- Accurate assessment of ductal anatomy is crucial for selecting appropriate treatment strategies.
- Understanding variations in PDA morphology is essential for advancing therapeutic interventions.
Purpose of the Study:
- To analyze the prevalence and characteristics of different types of patent ductus arteriosus (PDA) in pediatric patients.
- To provide data on ductal dimensions for optimizing current and developing novel closure techniques.
- To differentiate between ductus arteriosus persistens (DAP) and ductus arteriosus (DAA) in a large cohort.
Main Methods:
- Retrospective analysis of 563 consecutive heart catheter investigations in infants and children.
- Diagnosis and classification of 109 identified cases of open ducti, distinguishing DAP and DAA.
- Measurement of ductal dimensions in 89 cases for further analysis.
Main Results:
- 109 open ducti were diagnosed in 563 investigations.
- 75 children (13.3%) presented with ductus arteriosus persistens (DAP), and 34 with ductus arteriosus (DAA).
- Measurements of 89 ducti were obtained and categorized by age, type, and intended treatment.
Conclusions:
- The study provides valuable dimensional data on various forms of PDA in pediatric populations.
- These findings can inform the refinement of existing transcatheter closure methods.
- The data supports the development of new transvasal techniques for managing PDA as an aortopulmonary shunt.
Abstract:
In 563 consecutive heart catheter investigations in sucklings, infants and children 109 open ducti were diagnosed. 75 children (13.3%) had a ductus arteriosus persistens (DAP) and 34 a ductus arteriosus (DAA). We were able to measure 89 ducti. Groups were formed according to the age of the children, of DAP or DAA and the intended treatment. The sizes of the ducti constitute a set of data for improving the methods for closure or newly developed transvasal methods of conservation of the ductus as an aortopulmonary shunt.
