Myocardial Venous Bridge: Images of the First Cases Detected by Conventional Angiography and Venography

A myocardial bridge refers to the partial or complete encasement of coronary arteries by the myocardium. 1 In contrast, the myocardial venous bridge is less well-known and has only been identified in cadaver studies. 2 Its clinical relevance remains unclear.Watanabe et al. 2 described two forms of myocardial bridge: one involving the artery and another involving both the artery and the vein, with both structures enveloped by myocardial tissue in the latter type.Coronary artery disease (CAD) continues to be the leading cause of death globally.However, coronary venous disorders have received significantly less attention in research compared to CAD.Coronary veins-particularly the coronary sinus-are frequently utilized for guiding ablation procedures. 3These veins have been the focus of anatomical and imaging studies, with several anomalies in the coronary venous system reported. [4][5]5][6] A better understanding of the microvascular and coronary venous physiology may help clarify some unresolved aspects of cardiology.For instance, the pathophysiology of Takotsubo syndrome remains not fully understood. 7Advances in imaging technology, which have enhanced the study of coronary arteries, could similarly be applied to investigating diseases of the coronary venous system.
