Abstract

For intraoperative regulation: adequacy of valve failure correction, a semi-rigid ring is used, the presence of a flexible part 2 which in the form of a band allows to regulate the degree of narrowing of the fibrous one. The invention relates to medicine, namely to surgical methods and tools used in cardiac surgery. correction of mitral valve disease of the heart. The aim of the invention is the intraoperative regulation of the adequacy of the valve insufficiency correction by using a semi-rigid ring, the presence of the flexible part of which allows the degree of contraction of the mitral valve of the mitral valve to be adjusted. FIG. 1 shows a device for correcting mitral valve insufficiency, in section; in fig. 2 - hard part of the device; in fig. 3-6 - successive stages of surgical correction of mitral valve insufficiency. mitral valve rings. The hard part 1 of the ring, fitted along the length of the front flap of the valve, is poured to its base with U-shaped willows. From the ends of the rigid part, two opposite half-net seams are placed on the base of the posterior cusp, which are alternately tightened, constricting the fibrous ring until termination of reguriton, gating fluid introduced into the left ventricle under a pressure of 20-100 mm Hg. Art. The ends of the threads go down to the base of the back sash with separate interrupted seams, hem the flexible part of the artificial ring. The edges of the flexible and rigid parts are sewn together, 2 s.p. f-ly, 6 ill. (The device contains a rigid part 1 and a flexible part 2, which are connected to one another and have free ends. The flexible part is made as a braid. The method is carried out as follows. Two sutures are put on the fibrous ring in the area of the commissa valve length (Fig. 3), measure the length of the base of the front flap, i.e. the distance between the seams-tapes. Choose a semi-rigid ring with the length of the rigid part 1 equal to this distance. The rigid part of the ring is hemmed with a crochet trimming the base of the front flap is five Steam U-shaped seams (Fig. 3). From the ends of the hemmed rigid part impose two opposing single half-hews Od JV 1h5 O) o

Description

net luna on the base of the posterior cusp to its middle (Fig. 4), vcol steps of 3-4 mm. The ends of both threads are taken in one rigid turnstile with section-1 fixing the threads with clamps. The narrowing of the fibrous ring is performed by alternately tightening the half-set sutures before eliminating the regurgitation of fluid from the left ventricle, inserted from the cardioplegia apparatus through the drainage in the apex of the left ventricle into its cavity under pressure in the 0-100 mm Hg system. Art. After reaching the optimal contraction of the fibrous ring of the mitral valve, the flexible part 2 of the artificial ring is hemmed to the base of the posterior cuspid with separate interrupted sutures (Fig. 6). The edges of the flexible and rigid parts are stitched together.

Thus, the circumference of the fibrous ring created directly during the operation under the conditions of the hydraulic test is strictly individual, the opening of the opening is made to the extent necessary for the patient. Bending

2. A device for the correction of mitral valve insufficiency, containing rigid and flexible parts, connected to one another and having a semi-rigid ring, does not prevent the physiological movements of the posterior ends that differ from the semicircle of the fibrous ring, thus avoiding the possibility of intraoperative the eruption of regulation of the adequacy of the correction of the seams on the fibrous ring and the possible sufficiency of the valve, the flexible part of the recurrence of the mitral disease is insufficiently performed in the form of a band.

nosti. The hard part of the ring allows the transverse size of the fibrous ring to be reduced and to bring the sash together in the commissural areas.

Claims (2)

1. A method for correcting mitral valve insufficiency by sewing a semi-rigid ring to a fibrous ring of a mitral valve, characterized in that in order to intraoperatively regulate the adequacy of the valve insufficiency correction, the rigid part of the ring starts at the base of the anterior valve leaf, starting from its edges, impose a half-set seam two threads opposite to each other, the ends of the threads are tightened until the fluid is removed from the ventricle and the suture zgayat with the subsequent fixation of the flexible part of the ring to the portion of the fibrous ring, which is made up of semi-net seam, 2. A device for correction of mitral valve insufficiency, containing rigid and flexible parts, connected to one another and having their own bodice ends, characterized in that for the purpose of intraoperative regulation of the adequacy of valve failure correction, the flexible part is made in the form of a braid. 1 FIG. g 7 jig. 3 5 ssh.b Editor O.
