Abstract: With the emergence of coronary diseases, the interest of anatomists and cardiologists in the anatomical study of coronary arteries has increased. The multiple variations in their pattern of irrigation possibly have impact and an anatomical-clinical correlation between the type of irrigation and the different risks of myocardial infarction. The pattern of coronary artery distribution in the Mozambican population remains unknown since this type of study has not yet been performed. Objectives: identify possible patterns of coronary arteries in the Mozambican population. Metodology: 30 adult human hearts of both gender, who died from non- cardiovascular causes were study by injection of latex. Results: Right predominance was evident in 70% of the cases, balanced in 20% and left in 10%. In 63.3% of the cases the left coronary artery presented a bifurcation in to anterior interventricular and circumflex artery. In 33.3% of the hearts examined, the left coronary artery presented trifurcation in to anterior interventricular, circumflex and lateral branches. The artery of the sinuatrial node arise from right coronary artery in 66.7% of cases and 33.3% from the left coronary artery. The atrioventricular node artery in 93.3% of cases was arise from the right atrioventricular artery and 56.7% of the hearth had no bridges. 40% of the hearts had 1/5 of the posterior face irrigated by the anterior interventricular artery. 30% of the cases presented 6 diagonal branches. Conclusion: Coronary artery and its branches present many variations and should be important to do more studies in order
