Repair Ring Adapts to Heart’s Natural Valve


March 15, 2011

The Contour 3D Annuloplasty Ring, from Medtronic is designed to restore normal valve function by remodeling the natural valve’s shape and size.

Tricuspid dilation is a progressive disease that eventually leads to severe tricuspid regurgitation (TR), which occurs when the tricuspid valve leaflets do not close properly, allowing blood to flow opposite of the intended direction. For patients with significant dilation of the tricuspid annulus (or opening), surgeons typically recommend surgical repair with an annuloplasty ring or band to restore the normal annular dimensions and normal leaflet closure. This also provides the necessary long‐term support of the native annulus.

The ring is based on computed tomography (CT) images from normal tricuspid valves. It also was designed to avoid interference with the heartʹs conduction system and to ensure that valve leaflets open and close effectively while preventing regurgitation.
