“…[ 2 ] Studies have confirmed that 67% to 98% of MB occur in the mid-left anterior descending branch, [ 3 , 4 ] but they can also occur in any epicardial coronary artery such as the posterior descending branch of the right coronary artery, the posterior interventricular branch or the spinous branch. [ 5 ] Based on their anatomical morphology, MB can be categorized into superficial MB located in the interventricular groove and deep MB located close to the right ventricular septum. [ 6 ] Currently, MB is considered a benign anatomical variant, but some significant concomitant symptoms have been reported in the literature, such as stable angina pectoris, myocardial infarction (MI), malignant arrhythmias, and even sudden cardiac death.…”

Background: The aim of this study is to analyze the process and frontiers of research in myocardial bridges (MB) to identify future research directions in the last 3 decades. Methods: Relevant literature on MB combined with myocardial infarction (MI) was searched from 1991 to 2023 in the Web of Science database, and was analyzed by bibliometric analysis using VOSviewer, CiteSpace, and the R package “bibliometrix.” Results: A total of 1233 English articles were included in this study. The number of published articles showed an increasing trend yearly. From 2017 to 2022, the annual publication volume rose rapidly, and in 2021 the publication volume even reached 95 articles, which was the highest in all years. These publications were from 68 countries and 1854 institutions, with the leading country being the U.S. and the leading institution being Columbia University. Myoho Clinical International has a close collaborative relationship with Columbia University, while in recent years, the Harvard Medical School has explored the study of MB combined with MI. Annals of Thoracic Surgery was the journal with the highest number of publications, and Takayama Hiroo and Naka Yoshifumi were the authors with the highest number of publications. The most common keywords were MI, cardiogenic shock, and MB. Conclusions: Our findings can help researchers explore the current status of MB combined with MI research and choose new survey routes for upcoming studies. Prevalence and prognosis, mechanism of MB combined with MI and molecular mechanism may become the focus of future research. In addition, more research and cooperation are needed worldwide.

“…Coronary arteries are usually distributed on the surface of the epicardium, and occasionally segmental blood vessels run through the myocardium[ 1 ]. When this blood vessel is compressed by 70% in systole and 35% in late diastole, it is called a myocardial bridge[ 2 ].…”

BACKGROUND Severe stenotic myocardial bridges (MBs) have been reported to lead to intracoronary ischaemia, but the physiological evaluation of MBs using intracoronary function evaluation indicators after intraoperative drug treatment has not been fully established. CASE SUMMARY We performed through snuff fossa for coronary angiography in a patient with chest tightness after repeated exercise, and the results showed that the middle part of the anterior descending branch was a MB with 100% systolic compression. The intracoronary function evaluation (defined as the ratio of distal coronary pressure to aortic pressure with zero microcirculation resistance) was instantaneous wave-free ratio (IFR) without drug and fractional flow reserve (FFR) with adenosine. The IFR was 0.73, and the FFR was 0.66. Then esmolol 0.02 µg/kg/min was intravenously injected. The IFR and FFR were measured again when the heart rate dropped to 60 beats/min. The IFR was 0.83, and the FFR 0.65. CONCLUSION This case report is a case of isolated MB with severe stenosis. After intraoperative drug treatment decreased the ventricular rate, an increase in the coronary function evaluation index was immediately observed to confirm the effective improvement of coronary blood flow.
