Insights
Percutaneous pulmonary valvuloplasty is an effective treatment for moderate pulmonary stenosis in children. While complications like failure and mortality occurred, they were not significantly higher in younger children, suggesting safety across pediatric age groups.
Area of Science:
- Pediatric Cardiology
- Interventional Cardiology
- Congenital Heart Disease
Background:
- Pulmonary stenosis is a common congenital heart defect.
- Percutaneous balloon valvuloplasty is a primary treatment modality.
- Understanding outcomes across pediatric age groups is crucial.
Purpose of the Study:
- To evaluate the characteristics and outcomes of percutaneous pulmonary valvuloplasty.
- To compare treatment results among three pediatric age cohorts.
- To identify factors influencing procedural success and complications.
Main Methods:
- Retrospective analysis of pediatric patients (<15 years) undergoing pulmonary valve balloon valvuloplasty.
- Data collected from 2005-2009 at Madani Heart Center.
- Statistical analysis using IBM SPSS software.
Main Results:
- Mean patient age was 55.5 ± 47.4 months.
- Two-thirds of patients had moderate pulmonary stenosis.
- Procedural failure occurred in nearly 20% of patients, with 2 mortalities.
- Mild pulmonary valve insufficiency was a frequent finding.
- Complication rates were descriptively lower in older children (>5 years) but not statistically significant.
Conclusions:
- Percutaneous pulmonary valvuloplasty is a viable treatment for pediatric pulmonary stenosis.
- The procedure demonstrates acceptable safety and efficacy across different childhood age groups.
- Further research may elucidate statistically significant differences in outcomes based on age.
Abstract:
The aim of this study was to investigate the characteristics and outcomes of treating pulmonary stenosis with percutaneous valvuloplasty, and to compare them among three childhood age groups. All children under 15 years of age who had undergone pulmonary valve balloon valvuloplasty in Madani Heart Center from 2005-2009 were enrolled in this study. Data were analyzed using IBM SPSS software (SPSS, Inc, Chicago, IL). Mean (± standard deviation) age of patients was 55.5 ± 47.4 months. Two-thirds of the subjects had moderate pulmonary valve stenosis. Balloon valvuloplasty failed in nearly one-fifth of the treated patients. There were 17 failures and two cases of mortality, descriptively less frequent among children >5 years; however, the observed difference was not statistically significant. Mild pulmonary valve insufficiency was a common finding.

Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
