Core Tip

Core Tip: Myocardial bridge is one of the causes of myocardial ischaemia, and some studies have found that the degree of ischaemia is positively correlated with the degree of systolic compression. In this case of severe stenosis, after intraoperative drugs reduced the ventricular rate of the patient, the coronary ischaemia improved. This is a relatively novel change in coronary function that was determined by evaluation indices.
