Balloon Angioplasty
A catheter-based interventional procedure using an inflatable balloon to dilate narrowed blood vessels or cardiac structures in congenital heart disease.
Full Definition
Balloon angioplasty is a minimally invasive transcatheter intervention used to treat stenotic lesions in congenital heart disease by mechanically dilating narrowed vessels or cardiac structures. The procedure involves advancing a deflated balloon catheter across the stenotic area and inflating it under controlled pressure to disrupt the obstructing tissue and increase the luminal diameter. In congenital cardiology, balloon angioplasty is commonly employed for pulmonary artery stenosis, branch pulmonary artery stenosis, coarctation of the aorta, and conduit stenosis. The technique may be enhanced with cutting balloons or high-pressure balloons for resistant lesions, and stent implantation may follow to maintain vessel patency.
Usage
Usage note: Specify the anatomic location and balloon size when describing procedures.
