| ABSTRACT |
| Background The coronary sinus is increasingly being used for cardiovascular interventional procedures. Thebesian valve, an endocardial remnant located at the coronary sinus opening into the right atrium, can hinder catheterization of the coronary sinus. The valve morphology varies between individuals. Despite its clinical relevance, data on its prevalence and morphology, particularly by sex, especially in African population, remain limited. Therefore, this study aimed to investigate the prevalence and sex-related structural differences in the Thebesian valves. Methods A total of 100 post-mortem hearts (63 males, 37 females) were examined. The coronary sinus and Thebesian valve were measured, photographed, and classified by morphology. Data were analyzed using appropriate statistical tests, including Mann-Whitney U and Spearman’s correlation. Results The Thebesian valve was present in 73% of hearts and showed varied morphologies. Absence of the valve was associated with a larger coronary sinus opening. Percentage occlusion of the coronary sinus opening was higher in males, though sex-related structural differences were not statistically significant. Age showed no influence on valve morphology. Positive correlations were observed between heart size and coronary sinus dimensions. In conclusion, the study highlights anatomical variations that may impact interventional procedures involving the coronary sinus. Keywords: Thebesian valve, coronary sinus, prevalence, variations. |
