摘要：
(57) The three-dimensional closed support ring of the mitral valve refers to medicine, namely cardiac surgery. The support ring can be used for reconstructive operations on the mitral valve of the heart. The three-dimensional support ring of the mitral valve is a closed rigid fixation ring that repeats the shape of the fibrous ring of the mitral valve. The support ring is made of two arches, front and rear, eccentrically bent upward to different heights (in the shape of the saddle). The support ring in the horizontal section has the shape of an oval. The larger diameter of the oval has a predetermined value "a". The small diameter is 0.8a. The inter-commissural axis, along which the saddle bending of the bases of the anterior and posterior segments of the ring occurs, runs parallel to the larger diameter of the oval. The inter-commissural axis is separated from the top of the arc of the front section by 0.26a. The base of the anterior wing rises above the intercrossural axis by 0.1a, and the base of the posterior wing rises above the intercrossural axis of the oval by a value of 0.05a. The saddle shape of the ring reduces the stress of the valves and fibrous ring more than 2 times. Certain proportions of the ring parameters make it possible to produce several standard sizes of support rings with a pre-formed geometry of the implantable support ring, depending on the anatomical and physiological characteristics of the patient. 2 zpf-ly, 4 ill.
