Insights
A rare case of a cavernous haemangioma in the coronary sinus is presented. This vascular tumor caused coronary fistulas and was successfully removed surgically.
Area of Science:
- Cardiology
- Vascular Surgery
- Pathology
Background:
- Coronary artery anomalies are rare congenital conditions.
- Coronary sinus abnormalities can lead to complex cardiovascular presentations.
- Persistent left superior vena cava is a rare congenital anomaly.
Observation:
- A 58-year-old man presented with chest discomfort and dyspnea.
- Coronary angiography revealed fistulas between the coronary sinus and coronary arteries.
- The coronary sinus drained into a persistent left superior vena cava, not the right atrium.
Findings:
- A mass within the coronary sinus was suspected to be a thrombus.
- Transoesophageal echocardiography confirmed a mass in the atrioventricular groove.
- Surgical removal revealed the mass to be a cavernous haemangioma.
Implications:
- This case highlights a rare cause of coronary fistulas.
- Cavernous haemangioma should be considered in the differential diagnosis of coronary sinus masses.
- Successful surgical management of this rare anomaly is demonstrated.
Abstract:
A 58 year old man with a history of cerebral infarction was admitted to hospital with chest discomfort and dyspnoea. He had no history of precordial chest discomfort. Angiography and left ventriculography showed that coronary fistulas connected the coronary sinus with the left circumflex and right coronary arteries. His coronary sinus did not communicate with the right atrium, draining instead into a persistent left superior vena cava. Angiography showed a mass, suspected to be a thrombus, in the coronary sinus. Transoesophageal echocardiography confirmed the presence of a mass in the atrioventricular groove. The mass was removed at surgery and proved to be a cavernous haemangioma.

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 middle...
