Case in brief
A 63-year-old woman experienced intermittent palpitations, leading to the discovery of a congenital coronary arteriovenous fistula (CAVF) via transoesophageal echocardiography. This imaging revealed a high-velocity shunt from the left circumflex artery into an enlarged coronary sinus. Surgical closure was successfully performed, confirming shunt resolution intraoperatively.
What made this case unusual
The case involved a complex congenital coronary arteriovenous fistula associated with a circumflex aneurysm and significant coronary sinus dilatation, which are not commonly reported together.
Diagnostic / clinical pearl
Multimodal imaging, particularly the combination of echocardiography and CT angiography, is crucial for accurate diagnosis and surgical planning in complex cases of coronary arteriovenous fistula.
Why it matters
This case underscores the importance of timely intervention in preventing irreversible myocardial damage in patients with anatomically complex vascular anomalies.
