Variations of coronary arteries in cadavers referred to Tehran forensic medicine organization Variations of coronary arteries

Aim: Coronary artery disease is the most common cause of death worldwide and is a major cause of hospitalization. The aim of this study was to determine variations in the coronary arteries for use in diagnosis and treatment. Material and Method: In this observational study, we evaluated the data on 1,001 cadavers referred to the Tehran Legal Medicine Organization during 2012. Baseline demographic and anatomical characteristics were collected, and data were analyzed. Results: A total of 1,001 cadavers (206 female and 795 male) aged 40-80 years (mean age = 51, median age = 49) were dissected in this study. All cadavers had two or more coronary artery branches, but the right branch had the most common anatomical dominance pattern; 877 (88%) were right dominant, 94 (9%) were left dominant, and 30 (0.3%) were codominant. The frequency of variations in male was greater than in female, and differences between male and female cadavers were significant for the number of right and left coronary artery branches. Discussion: We found that anatomical diversity of the coronary arteries is more prevalent than in other arteries, and the right coronary artery has the most common anatomical dominance pattern. Moreover, there were no apparent differences from other study findings worldwide.
