State the exact location of the Chordae tendinae - Biology. Together, the papillary muscles and the chordae tendineae are known as the subvalvular apparatus. The pulmonary valve is located at the base of the pulmonary trunk, and the left semilunar valve is located at the base of the aorta. Interestingly, the chordae tendineae in this case also acted as a protective filter and prevented a massive fatal PE. The material properties of the mitral valve chordae tendineae are important for the understanding of leaflet coaptation configuration and chordal pathology. There are five papillary muscles in total. Based on the results, although the linear elastic model exhibits an acceptable correlation in the location of high stress regions with the hyperelastic model but Stress magnitudes differ between the elastic and hyper elastic model . The pulmonary valve is located at the base of the pulmonary trunk, and the left semilunar valve is located at the base of the aorta. The chordae tendinae keep blood from flowing back into the atria after passing into the ventricles. The chordae tendineae, or heart strings, are cord-like tendons that connect the papillary muscles to the tricuspid valve and the mitral valve in the heart.Ch. Mitral valve (MV) regurgitation (MR) is the second most common heart valve disease with an increasing incidence [].Roughly 12,300 MV procedures were performed in Germany in 2017 [].Patients with MR exhibit defects in the leaflets, annulus, or chordae tendineae (CT, tendinous cords), but other pathological alterations are possible as well. These are situated between the edges of the tricuspid and mitral valve of the heart and on the other end of the papillary muscles. However, early repair of the TV is of great importance, as it might prevent further exacerbation of the regurgitation due to remodeling . However, these simplifications cannot be used when investigating the roles of individual chordae Once filled with blood, the AV valves form a dome shape and resemble tiny parachutes with the chordae tendineae acting as the strings. The chordae tendineae connect the atrioventricular valves to the papillary muscles within the ventricles. The collagenous strands along with the opening of the coronary sinus and the septal cusp of the tricuspid valve form the triangle of Koch with the tendon of Todaro.
