Pulling on your heart strings The chordae tendineae or ‘heart strings’ are fibrous strings that attach to the flap-like openings between the upper and lower chambers of the heart. They stop these flaps from buckling as the blood flow changes pressure inside the respective chambers. Prof Bruce Murphy and team at the Science Foundation Ireland funded AMBER Centre in Trinity College have measured the fatigue strength of the chords in an effort to design predictive models of their life span, particularly in relation to diseases of the heart. www.ambercentre.ie 74
