Chordae Tendineae: The Hidden Key to Preventing Heart Valve Catastrophes When it comes to heart health, most people focus on chambers like the atria and ventricles—or perhaps the famous aortic and mitral valves. But behind the seamless opening and closing of these valves lies an often-overlooked structure: the chordae tendineae. These delicate yet vital components are essential in preventing life-threatening heart valve disorders, making them a hidden key in cardiovascular protection. ### What Are Chordae Tendineae? Chordae tendineae—plural of chordae tendineae—are fibrous cords connecting the valve leaflets in the heart to small, stiff structures called papillary muscles. Located primarily in the mitral and tricuspid valves, these thread-like bands act like secure anchors, ensuring the valve leaflets don’t prolapse (protrude abnormally) into the ventricles during the powerful contraction phase of the heartbeat.
