Summary
The coronary sinus valve, crucial for heart function, most commonly appears semilunar in shape. Its absence was noted in over a third of the 143 hearts studied.
Area of Science:
- Anatomy
- Cardiovascular System
- Venous System
Background:
- The coronary sinus is a major vein collecting deoxygenated blood from the heart.
- Understanding the anatomy and variations of the coronary sinus and its valves is important for cardiovascular research and clinical practice.
Purpose of the Study:
- To investigate the morphology and variations of the coronary sinus and its associated valves.
- To describe the different forms of the coronary sinus valve and the valve of Vieussens.
- To analyze the relationship between venous walls and cardiac structures.
Main Methods:
- Examination of 143 human hearts across various age groups.
- Detailed observation of the coronary sinus, its tributaries, length, and ostium.
- Documentation of the presence, form, and absence of coronary sinus valves and the valve of Vieussens.
Main Results:
- The semilunar form was the most frequent type of coronary sinus valve observed (52 adults, 15 youngsters, 2 children, 3 newborn).
- Valve absence was noted in 53 cases (42 adults, 9 youngsters, 2 newborn).
- The valve of Vieussens and other parietal venous valves were also identified.
Conclusions:
- The study provides detailed anatomical data on coronary sinus valve morphology and prevalence.
- Variations in coronary sinus valve structure, including absence, are common.
- Further research into the functional implications of these anatomical variations is warranted.
