Abstract: The proximal segment of myocardial bridge is prone to coronary atherosclerosis. This may lead to myocardial ischemia, which can result in angina, acute coronary syndrome(ACS), left ventricular dysfunction, syncope and even sudden cardiac death. However, there is lack of mechanisms and robust data. This article reviews the recent advances of patented technology in China, including coronary artery and heart pump simulation devices, myocardial bridge simulation and image acquisition equipment, traditional Chinese medicine, pulsed field ablation and stent implantation equipment of myocardial bridge.

Key words: myocardial bridge, coronary artery, myocardial bridge image, patent
