balloon angioplasty
Interventional catheterization procedure using an inflatable balloon to widen narrowed blood vessels in pediatric cardiac patients.
Full Definition
Balloon angioplasty is a minimally invasive catheterization procedure commonly performed in pediatric cardiology to treat stenotic lesions in blood vessels and heart structures. A deflated balloon catheter is positioned across the narrowed area and then inflated to stretch the vessel or valve. In pediatric patients, this technique is frequently used for pulmonary artery stenosis, aortic coarctation, and pulmonary valve stenosis. The procedure offers an alternative to open surgery for many conditions, though some lesions may require stent placement for optimal results. Success rates vary depending on the location and severity of the stenosis.
Usage
Usage note: Distinguish from balloon valvuloplasty, which specifically targets valve structures rather than vessel stenosis.
