Giant Intramyocardial Aneurysm in a Patient with Intercoronary Communication between the Left Circumflex Artery and
Insights
A rare giant coronary artery aneurysm was found incidentally in a patient
Area of Science:
- Cardiology
- Radiology
Background:
- Coronary artery aneurysms are uncommon vascular abnormalities.
- They typically occur along major epicardial coronary arteries.
Observation:
- A case of a giant left ventricular aneurysm was incidentally discovered.
- The patient presented with cardiac palpitations and had no significant medical history.
Findings:
- Echocardiogram and cardiac CT revealed a giant left ventricular aneurysm.
- The aneurysm had a fistulous connection to the left circumflex artery.
- The left circumflex artery communicated with the right coronary artery.
Implications:
- This case highlights an unusual presentation of coronary artery aneurysm.
- It underscores the importance of advanced imaging in diagnosing complex cardiac conditions.
- Such findings can inform diagnostic and treatment strategies for rare cardiovascular diseases.
Abstract:
Coronary artery aneurysm is a rare disease. It occurs in the epicardial space, mostly along the course of major coronary arteries. Here, we report a case of a giant incidental aneurysm embedded in the basal posterior wall of the left ventricle. A 43-year-old woman was referred to our institution for the evaluation of cardiac palpitations that had been present from the previous 2 months. She reported no medical history (such as Kawasaki's disease or hypertension) or previous operative history. Echocardiogram and subsequent cardiac CT revealed a giant aneurysm in the left ventricle, with a direct fistulous connection to a dilated and tortuous left circumflex artery, which showed direct communication with the straight right coronary artery.

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...
