Functional regurgitation will usually lead to annular dilatation and increased tricuspid leaflet tethering due to pressure and volume overload of the RV.
WebThe leaflets attach to the papillary muscles of your heart (located in your left ventricle) with thin, strong cords called chordae tendineae. Near the chordae tendineae, on the surface of the valve, there’s an area called the zone of coaptation. This is the portion of the leaflets that touch when the valve is in the closed position.
