valve commissurotomy
Surgical division of fused valve commissures to improve valve function and blood flow.
Full Definition
Valve commissurotomy is a cardiac surgical procedure that involves the precise division or splitting of fused commissures in stenotic heart valves, most commonly the mitral or aortic valve. The technique aims to separate the valve leaflets that have become adherent due to rheumatic disease or congenital abnormalities. This procedure can be performed through open surgical approach or percutaneously, depending on the valve involved and patient anatomy.
Usage
Usage note: Prefer 'valve commissurotomy' over 'commissurotomy' alone for clarity in cardiac contexts.
