valvuloplasty
Pronunciation: val-vyuh-loh-PLAS-tee
A surgical procedure to repair or reconstruct a heart valve while preserving the native valve structure.
Full Definition
Valvuloplasty encompasses various surgical techniques aimed at restoring normal valve function while maintaining the patient's native valve tissue. These procedures include commissurotomy for stenotic valves, leaflet repair for regurgitant valves, and annular reconstruction for dilated valve rings. Mitral valvuloplasty may involve leaflet resection, chordal repair, or ring annuloplasty. Aortic valvuloplasty is less common due to limited durability but may be considered in specific scenarios. The primary advantage of valvuloplasty over valve replacement is the preservation of native tissue, potentially avoiding anticoagulation and providing better hemodynamic function.
Usage
Usage note: Distinguish from balloon valvuloplasty (percutaneous procedure) and valve replacement.
