Balloon Dilation
A catheter-based intervention using an inflatable balloon to relieve vascular or valvular stenosis.
Full Definition
Balloon dilation is a minimally invasive catheter-based technique used to treat various forms of cardiovascular stenosis in pediatric patients. The procedure involves advancing a deflated balloon catheter to the site of narrowing and inflating it under high pressure to stretch or fracture the stenotic area. This technique is commonly used for pulmonary valve stenosis, aortic valve stenosis, coarctation of the aorta, and branch pulmonary artery stenosis. Success rates are generally high, though some patients may require repeat procedures or eventual surgical intervention.
Usage
Usage note: Also called balloon valvuloplasty when applied to valves; distinguish from surgical dilation.
