Insights
Rare coronary venous anomalies, like a great cardiac vein draining into the superior vena cava, are critical for cardiac surgeons. Pre-intervention imaging may improve patient safety during procedures.
Area of Science:
- Cardiovascular Anatomy
- Interventional Cardiology
- Cardiac Surgery
Background:
- Anomalous coronary venous anatomy is understudied and crucial for interventions assuming normal venous structures.
- Recognizing anomalies disconnecting myocardium from the coronary sinus is vital for cardiothoracic surgeons.
- Retrograde cardioplegia and coronary venous retroperfusion rely on intact coronary sinus connections.
Observation:
- A rare case of an anomalous great cardiac vein is presented.
- This anomalous vein bypassed the coronary sinus.
- The vein drained directly into the superior vena cava.
Findings:
- The study details a specific coronary vein anomaly.
- The great cardiac vein's unusual drainage pattern was identified.
- This finding highlights a deviation from typical coronary venous anatomy.
Implications:
- Antecedent imaging of the coronary venous system may be beneficial.
- Pre-procedural imaging could enhance patient safety in cardiac interventions.
- Understanding rare venous anomalies is critical for surgical planning and success.
Abstract:
Anomalous coronary venous anatomy is a little studied and rarely reported subject that is of crucial importance in interventions that rely upon the assumption of normal coronary venous anatomy. In particular, the recognition of coronary vein anomalies that disconnect large segments of the left ventricular myocardium from the main coronary sinus is critical for cardiothoracic surgeons who perform interventions involving retrograde cardioplegia and other forms of coronary venous retroperfusion. We present a rare case of an anomalous great cardiac vein that bypassed the coronary sinus to drain directly into the superior vena cava, and suggest a possible role for antecedent imaging of the coronary venous system in patients who might be expected to undergo such interventions.

01:11Overview 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 middle...
01:21Coronary 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...
01:19Veins 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.

01:11Overview of Systemic Arteries
Systemic circulation is the part of the cardiovascular system that carries oxygenated blood away from the heart to the body's tissues and returns deoxygenated blood back to the heart.
