annuloplasty
Pronunciation: an-yuh-loh-PLAS-tee
Surgical repair of a heart valve annulus using sutures or prosthetic rings to restore proper valve function.
Full Definition
Annuloplasty is a surgical technique used to repair diseased or dilated heart valve annuli by reducing their circumference and reshaping their geometry. The procedure most commonly involves the mitral or tricuspid valve annulus and can be performed using suture techniques or prosthetic rings/bands. The goal is to restore competent valve function by correcting annular dilatation that leads to regurgitation. Different types of annuloplasty rings are available, including rigid, semi-rigid, and flexible designs, each with specific advantages depending on the valve pathology and patient factors. Annuloplasty is often combined with other valve repair techniques for optimal results.
Usage
Usage note: Specify the valve (mitral annuloplasty, tricuspid annuloplasty) and type of repair when relevant.
