Insights
The middle cardiac vein, a coronary sinus tributary, was found to drain into the left atrium in a cadaver. This anomalous opening was protected by a semilunar valve.
Area of Science:
- Anatomy
- Cardiovascular System
- Medical Science
Background:
- The middle cardiac vein typically drains into the coronary sinus.
- Anatomical variations in cardiac venous drainage can impact cardiovascular health.
- Understanding coronary sinus tributaries is crucial for cardiac procedures.
Observation:
- A 79-year-old female cadaver presented an unusual anatomical configuration.
- The middle cardiac vein (V. cordis media) was observed opening directly into the left atrium.
- The ostium of this anomalous vein was guarded by a semilunar valve.
Findings:
- Anatomical variation: Middle cardiac vein draining into the left atrium.
- Presence of a semilunar valve at the atrial opening of the middle cardiac vein.
- This finding deviates from the typical venous drainage pathway into the coronary sinus.
Implications:
- This anatomical variation may have implications for electrophysiological studies and cardiac interventions.
- It highlights the importance of detailed pre-procedural anatomical assessment.
- Further research is needed to determine the clinical significance and prevalence of this variation.
Abstract:
The middle cardiac vein (V. cordis media) which is known to be one of the tributaries of the coronary sinus (Sinus coronarius) is found to open into the left atrium in a 79 years old female cadaver. The ostium is guarded by a semilunar (crescent shaped) valve.
