[Interventional cardiology in children].

Area of Science:

• Cardiology
• Interventional Cardiology
• Pediatric Cardiology

Context:

• Interventional heart catheterizations are therapeutic procedures.
• Balloon atrioseptostomy (BAS) is used for conditions like transposition of great arteries.
• Other procedures include foreign body retrieval, embolization, septal defect closure, and balloon valvuloplasty (BVP).

Purpose:

• To review the efficacy and complication rates of various interventional cardiac catheterization procedures.
• To evaluate the role of specific techniques like balloon atrioseptostomy and balloon valvuloplasty.
• To assess the safety and outcomes of interventional treatments for congenital and acquired heart defects.

Summary:

• Balloon atrioseptostomy (BAS) has a complication rate of 11.7% (10.5% minor, 1.2% lethal) in 248 procedures.
• Balloon valvuloplasty (BVP) for pulmonary stenosis shows a 4% complication rate.
• BVP for aortic stenosis has higher complication rates (20% in children, 50% in infants), suggesting it's a treatment of choice for pulmonary and non-critical aortic stenosis.

Impact:

• Interventional catheterizations provide crucial therapeutic interventions for complex pediatric and adult cardiac conditions.
• Understanding complication rates guides procedural selection and patient counseling.
• Further evaluation is needed for BVP in critical aortic stenosis and other valvular/vessel stenoses.
