DOMINANCE PROFILE OF THE CORONARY ARTERY IN AMAZONAS

The coronary arteries, along with their branches, supply arterial blood to the heart. Therefore, we aimed to evaluate the predominant pattern of coronary dominance in the Human Anatomy Laboratory -UEA. To assess the coronary dominance pattern, analyses were performed on 41 hearts belonging to the collection of the Human Anatomy Laboratory of the State University of Amazonas ). Data obtained at the Human Anatomy Laboratory (UEA) revealed that 81.8% of a total of 22 hearts presented the right coronary dominance pattern; 9.1% had left dominance; and 9.1% had codominance. According to the studies by Puladi et al. (2022), among 134 hearts analyzed, the percentage of right dominance was 73.1%, which exceeded left dominance (6.7%) and codominance (20.1%). This knowledge not only enriches anatomical understanding but also has significant practical implications, providing a solid foundation for improving therapeutic approaches and intervention strategies in complex cardiac contexts.
