Morphofunctional aspects of left coronary artery dominance: a case report

Anatomical studies of the coronary arteries began in the eighteenth century. However, the concept of dominance was only established in 1940, being initially purely anatomical. Currently, this concept involves several morphofunctional aspects, being essential for the understanding of the clinical presentations in cardiovascular patients. This article aims to discuss a case of left coronary dominance associated with risk factors such as hypertension, obesity and diabetes, but with less severe clinical presentations than those predicted in the literature, highlighting the importance of knowledge in clinical practice.
