1Department of Anatomy and Antropology, Jedrzej Sniadecki University School of Physical Education, Gdańsk.
Insights
This study examined the coronary sinus tributaries in 150 adult human hearts. Key cardiac veins were consistently observed, but other tributaries showed significant variability in their outlet portions.
Area of Science:
- Anatomy
- Cardiology
- Medical Science
Background:
- The coronary sinus collects deoxygenated blood from the heart walls.
- It is a crucial structure in invasive cardiology procedures.
- Understanding its tributaries is vital for clinical applications.
Purpose of the Study:
- To investigate the occurrence and anatomical variations of the main tributaries of the coronary sinus.
- To analyze the topography of the outlet portions of these cardiac veins.
- To provide anatomical data relevant to invasive cardiology.
Main Methods:
- Dissection and examination of 150 adult human hearts (both sexes, aged 18-85 years).
- Systematic observation of the coronary sinus and its primary venous tributaries.
- Documentation of the presence and anatomical course of the great cardiac vein, middle cardiac vein, and posterior vein of the left ventricle.
Main Results:
- The great cardiac vein, middle cardiac vein, and posterior vein of the left ventricle were consistently identified in all specimens.
- Other tributaries of the coronary sinus demonstrated less consistent occurrence.
- Significant anatomical variability was noted in the outlet portions of the main cardiac veins.
Conclusions:
- The study confirms the consistent presence of major cardiac veins draining into the coronary sinus.
- Anatomical variations in coronary sinus tributaries are common and clinically significant.
- Detailed anatomical knowledge of these variations is essential for successful invasive cardiac procedures.
Abstract:
The coronary sinus collects blood from the heart walls. It is a structure which presently plays a very important clinical role in invasive cardology. In this study, the occurrence of the main tributaries of the coronary sinus was examined as wall as the topography of their outlet portions. Material consistied of 150 adult human hearts of both sexes from aged 18 to 85 years. In the examined material, the graet and middle cardiac veins as well as the posterior vein of the left ventricle were always obserwed. The remaining tributaries of the coronary sinus were less stable. The outlet portions of the main veins of the heart were characterized by significant variability.
