Heart mitral valve mechanical property optimization method, system and equipment

Abstract

The invention discloses a heart mitral valve mechanical property optimization method. The method comprises the following steps: acquiring ultrasonic image data; importing the data into medical image processing software; extracting mitral valve features in the software; establishing an initial mitral valve three-dimensional curved surface model of the patient; designing a personalized artificial valve ring and formulating different virtual repair operation schemes to perform a virtual operation to obtain a three-dimensional curved surface model of the mitral valve after virtual operation repair; performing finite element pretreatment on the initial model and the model after the virtual operation repair to obtain multiple finite element models before and after the operation, and performing dynamic simulation in finite element analysis software to obtain mitral valve stress-strain distribution characteristics; and selecting a virtual operation scheme with the most uniform stress-strain distribution of the postoperative model. The invention also discloses a corresponding system and equipment. The method can be applied to a system integrating mitral valve repair operation scheme evaluation, the success rate of the annulus repair operation is improved, and the technology can be applied to training and teaching of doctors.

Description

technical field [0001] The invention relates to the field of medical image analysis and simulation, in particular to a method, system and equipment for optimizing the mechanical performance of a cardiac mitral valve. Background technique [0002] In recent years, the incidence of degenerative mitral regurgitation in my country has risen rapidly, and valve annulus repair surgery is the most important method to improve the symptoms of mitral regurgitation and improve the life expectancy of patients; , Inaccurate analysis of the mitral valve structure and inappropriate repair methods during the operation limited the development of valve annulus repair surgery. Establishing a three-dimensional surface model of the mitral valve before and after infusion and performing finite element simulation on the model can provide physicians with visual dynamic contrast effects and effective surgical plan evaluation methods, which can shorten the training period for physicians and improve the ...
