Insights
This study highlights rare cases of anomalous great cardiac veins draining into the left atrium. Understanding these coronary venous anomalies is crucial for cardiovascular health.
Area of Science:
- Cardiovascular Anatomy
- Cardiac Surgery
- Medical Imaging
Background:
- Coronary venous anomalies are infrequently documented compared to arterial variations.
- Understanding the anatomy of coronary veins is essential for surgical and diagnostic procedures.
Observation:
- Two distinct cases of anomalous great cardiac veins were identified.
- These anomalous veins exhibited an unusual drainage pattern.
Findings:
- Both cases demonstrated individual drainage of the great cardiac veins into the left atrium.
- This anatomical variation deviates from typical coronary venous drainage pathways.
Implications:
- Highlights the importance of recognizing rare coronary venous anomalies.
- May influence diagnostic approaches and interventional strategies in cardiac procedures.
- Contributes to the limited body of knowledge on coronary venous system variations.
Abstract:
Coronary venous anomaly is a less studied and rarely encountered subject in contrast to the coronary arterial system. In this article, we present 2 cases of anomalous great cardiac veins that drain into the left atrium individually.

Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the...
Coronary Circulation
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...
Veins of Thorax
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.
