“…The former should be modeled by a suitable definition of the reference natural bending and twist k 1o , k 2o and k 3o , possibly depending on the curvilinear coordinate s. The latter is described by external loads, in terms of forces and torques. In the large existing anatomical literature are reported several figures of excised mitral valves, laying on a flat surface [20][21][22][23][24]. Most of the pictures display a flat structure with a rather homogeneous curvature.…”

This paper investigates the role of mechanics in the morphogenesis of the annulus of the mitral valve. We represent the annulus in its embryonic stage as an elastic ring and we perform a mechanical simulation of the development process applying a distributed torque on the rod: because of the mechanical action of the other growing cardiac chambers on the atrio-ventricular region, it departs from a planar circular shape. The numerical integration of the mathematical rod model subject to a bending load yields a shape very near to the one reported in the medical literature as anatomical reference for healthy patients. To make the comparison quantitative, we illustrate a numerical approach to match two curves in 3D defining their distance in a proper mathematical way. Such a methodology is first applied to compare the annular shape resulting from the mechanical model with an anatomical reference “master” shape and it is then applied to set to clinical data extracted from MRI for a cohort of healthy patients. The good agreement among anatomical master description, numerical mechanical model, and clinical data supports our speculation about a possible role of mechanics in determining the shape of the mitral valve.

BACKGROUND The heart is a pair of valved muscular pumps combined in a single organ. For the proper functioning of the heart, all valves should be intact. Mitral valve (MV) prolapse and regurgitation is the main cause of MV replacement. The dimensions of mitral valve and the cusps vary from person to person. We wanted to measure the average size of the valve components with respect to the annulus in the cadavers of South Odisha region, which would help in the selection of prosthetic valve in cardiac surgery. METHODS This comparative study was carried out on 58 adult cadaveric human hearts. Left atrium was opened along the left border of heart so as to expose the mitral orifice. Parameters of different components ofthe valve were measured by using appropriate instruments. RESULTS The mean annular circumference of the mitral valve was found to be 8.84 ± 1.24 cm; The annular attachment and height of anterior cusp were 2.94 ± .81 cm and 2.55 ± 0.27 cm respectively. The annular attachment and height of posterior cusp were 4.52 ± 0.78 cm and 1.2 ± 0.17 respectively. The annular area was found to be 5.22 ± 1.13 cm2. The combined cusp area was found to be 9.38 ± 2.32 cm. CONCLUSIONS The size of mitral valve parameters in the South Odisha region were found to be less compared to other studies. This study might help cardio-thoracic surgeons as well as the prosthetic valve manufacturing companies for the rough estimation of the mitral valve size.
