The present application relates to a TAVR teaching model based on blood flow simulation and multi-modal image fusion and use method. The model comprises a simulated thoracic and abdominal cavity with a built-in heart wave beat simulation part that drives fluid to generate pulsatile blood flow, a simulated thoracic and abdominal body with pre-set vascular access, a bionic heart assembly with structures such as a ventricular cavity, a pathological valve module that can be detachably fitted to the aortic valve ring and contains a pressure sensor array and simulated calcification, a coronary circulation monitoring module that monitors the perfusion state of the coronary artery opening, a virtual fluoroscopy positioning module that generates real-time fluoroscopy images, and a central control console that electrically cooperates with each module. The scheme simulates the tactile sensation of calcification through the pathological valve module, the heart wave beat simulation part reproduces the physiological pressure difference with a closed loop blood flow, realizes image navigation training with non-radiation virtual fluoroscopy, integrates real-time simulation of complications with coronary monitoring and annulus pressure sensing, and solves the problems of existing models such as distorted hand feeling, inaccurate dynamics, dependence on radiation, and lack of complication training.
