valvuloplasty
Pronunciation: VAL-vyoo-loh-plas-tee
Minimally invasive procedure to repair or widen narrowed heart valves.
Full Definition
Valvuloplasty is a catheter-based interventional procedure used to treat stenotic (narrowed) heart valves by mechanically widening the valve opening. The most common type is balloon valvuloplasty, where a deflated balloon is positioned across the stenotic valve and inflated to stretch the valve leaflets apart. This procedure is primarily performed for mitral stenosis, pulmonary valve stenosis, and occasionally aortic stenosis in specific patient populations. While less invasive than surgical valve replacement, valvuloplasty may provide temporary relief and carries risks including valve regurgitation and restenosis.
Usage
Usage note: Distinguish from valvulotomy (surgical cutting) and valve replacement procedures.
