Multifunctional mitral valve shaping device

Abstract

The invention relates to a multifunctional mitral valve shaping device. The device includes an adjustable shaping ring body and a supporting member connected to the shaping ring body and used for supporting the deformation side of a left ventricle; the supporting member is far away from the shaping ring body end along the length direction and has a ring structure, so that forming of an effective support for the displacement and deformation of the left ventricle is facilitated; the device facilitates ensuring that the front and rear valve leaflets are remained in the normal position and facilitates the normal closure of the front and back valve leaflets during systole under the premise that papillary muscles are not damaged when chordae tendineae falls or is broken, facilitates avoiding secondary mitral valve regurgitation with different degrees, and solves the problem of different degrees of mitral valve regurgitation secondary to displacement deformation; and the device has the advantages of a simple structure, convenient operation, a simple manufacturing process, low manufacturing costs and higher reliability.

Description

technical field [0001] The invention relates to a mitral valve forming device, in particular to a multifunctional mitral valve forming device. Background technique [0002] Ischemic mitral regurgitation (ischemic mitral regurgitatiolq, IMR) is mitral regurgitation secondary to ischemic heart disease and myocardial infarction. In view of the absence of typical pathological lesions in the mitral valve leaflets and chordae, IMR is understood as a functional mitral regurgitation. [0003] Compared with replacement, the existing mitral annuloplasty is easier to maintain excellent hemodynamic characteristics, promote the recovery of left heart function, and the incidence of perioperative complications such as death, thromboembolism, bleeding, and endocarditis is also lower. Lower, postoperative free from regurgitation is also significantly better than mitral valve replacement. However, although plastic surgery is safe, easy to perform, and has few complications, there are still ...
