A case report of a coronary artery fistula to coronary sinus with giant aneurysm: risk does not end with repair.

ABSTRACT:

Background

Isolated coronary arteriovenous fistulas are extremely rare, accounting for 0.08-0.4% of all congenital heart disease. Closure of the fistula is recommended in cases of large dimensions, relevant left-right shunt, or ischaemic events. Thrombosis of the coronary aneurysms may occur as a postoperative complication.

Case summary

We report a case of a coronary fistula between the circumflex artery and coronary sinus with giant aneurysm. After a failed percutaneous closure attempt, the patient was surgically treated without major postoperative complications. Despite therapeutic anticoagulation and antiplatelet therapy, she presented at clinical follow-up with thrombosis of the dilated coronary artery without signs or symptoms of ischaemia.
