Insights
Pulmonary artery stenosis in children can lead to heart failure. Advances in percutaneous treatments, like balloon angioplasty and stenting, have significantly improved outcomes for pediatric patients.
Area of Science:
- Pediatric Cardiology
- Interventional Cardiology
- Congenital Heart Disease
Abstract:
Pulmonary artery stenoses are a common problem in pediatric cardiology. They may interfere with the growth and development of the lung and cause pressure overload on the right heart and by increasing pulmonary arterial valvular insufficiency, also volume overload on the right ventricle. This may predispose the patient to cardiac failure, limitation of exercise tolerance and arrhythmias. Percutaneous treatment of pulmonary artery stenoses has undergone significant development over the last 20 years. Above all, the development of high pressure balloon catheters and stents has made treatment results better.
