ANATOMY

Detailed explanation-1: -Tiny white collagenic cords called the chordae tendineae (literally, heart strings) anchor the cusps to the ventricular walls. The chordae tendineae originate from small bundles of cardiac muscle, papillary muscles, that project from the myocardial wall.

Detailed explanation-2: -The chordae tendinae are thin strands of connective tissue that anchor the leaflets of each AV valve so that they cannot open into the atrium (thus allowing backflow of blood into the atrium).

Detailed explanation-3: -The two atrioventricular valves, the mitral valve, and the tricuspid valve, are connected to the ventricles by thin, fibrous strands of tissue called chordae tendineae. The chordae tendineae, along with papillary muscle hold the flaps, or cusps, of each valve in place.

Detailed explanation-4: -Attached to each of the AV valve flaps are tiny white collagen cords called the chordae tendineae or “heart strings, ” that anchor the cusps to the papillary muscles protruding from the ventricular walls.

Detailed explanation-5: -The AV valves are anchored to the wall of the ventricle by chordae tendineae (heartstrings), small tendons that prevent backflow by stopping the valve leaflets from inverting.
