which valves are anchored by chordae tendineae

These are the mitral and tricuspid valves which are situated between the atria and the ventricles and prevent backflow from the ventricles into the atria during systoleThey are anchored to the walls of the ventricles by chordae tendineae which prevent the valves from inverting. ICD-10-CM and ICD-10-PCS coding information from the American Hospital Association - subscription required also ICD-9-CM.

Chordae Tendinae Whitman College

The mitral and tricuspid valves are supported by the attachment of fibrous cords chordae tendineae to the free edges of the valve cusps.

. The chordae tendineae are attached to papillary muscles that cause tension to better hold the valve. The chordae tendineae are in turn attached to papillary muscles located on the interior surface of the ventricles these muscles contract during ventricular systole to prevent prolapse of the valve leaflets into the atria.
