What is the chordae tendineae made of?
What is the chordae tendineae made of?
The chordae tendineae (tendinous cords), colloquially known as the heart strings, are tendon-resembling fibrous cords of connective tissue that connect the papillary muscles to the tricuspid valve and the mitral valve in the heart.
Why are chordae tendineae so strong?
The chordae tendinae (CT) are strong, fibrous connections between the valve leaflets and the papillary muscles. These are attached to the leaflets on to the ventricular side and prevent the cusps from swinging back into the atrial cavity during systole.
What is the chordae tendineae?
Chordae tendineae: Thread-like bands of fibrous tissue which attach on one end to the edges of the tricuspid and mitral valves of the heart and on the other end to the papillary muscles, small muscles within the heart that serve to anchor the valves.
What kind of tissue is the chordae tendineae?
Chordae tendineae. The chordae tendineae (tendinous cords), colloquially known as the heart strings, are tendon -resembling fibrous cords connective tissue that connect the papillary muscles to the tricuspid valve and the bicuspid valve in the heart . Chordae tendineae are approximately 80% collagen,…
What are the three main types of chordae?
There are three main types of chordae: primary (marginal) chordae, secondary (basal) chordae, and tertiary chordae. What do the chordae tendinae look like? The tendinous chordae are made up of collagen (a protein in human connective tissues), elastin, and endothelium.
Where are the tendinous cords of the heart located?
The chordae tendineae (tendinous cords), colloquially known as the heart strings, are tendon-resembling fibrous cords of connective tissue that connect the papillary muscles to the tricuspid valve and the bicuspid valve in the heart.
Where do chordae tendineae connect to the tricuspid valve?
In the right ventricle, the chordae tendineae connect to the three cusps of the tricuspid valve, while in the left ventricle they connect to the two cusps of the bicuspid (or mitral) valve.

What causes the rupture of the chordae tendineae?
Valvular heart disease can lead to ruptured chordae tendineae. This can cause severe mitral insufficiency. Parachute mitral valve occurs when all the chordae tendineae of the mitral valve attach to a single papillary muscle. This causes mitral valve stenosis at an early age. It is a rare congenital heart defect.
