The chordae tendineae, or heart strings, are cord like structures that connect the Mitral and tricuspid valve to the papillary muscles. The functions of chordae tendineae are: 1) bring the right ventricular walls closer together during contraction. 2) pull the semilunar valves open to allow ventricular ejection.
The chordae tendineae have their origin by the tip of the papillary muscles and insert on the rough zone of the mitral leaflets. 41,46 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.
