Chordae tendinae

Delicately puts his finger under the papillary muscles and the chordae tendinae in the heart!! Chordae tendinae are cords that have their origin by the tip of the papillary muscles and insert on the rough zone of the mitral or tricuspid valve leaflets. After their origin and before their insertion, they split in numerous branches and interconnections that ensure a balanced distribution of the mechanical forces among chordae. They make up the leaflet suspension system that ultimately determine and maintain the position and tension on the valve leaflets at end of systole and prevent eversion or prolapse of these valves into the right or left atria, thereby preventing regurgitation (or back flow) of ventricular blood into the atrium during systole. Regurgitation can be the result of papillary dysfunction or chordate rupture, which commonly happened following an acute myocardial infarction.
