Monster left circumflex artery fistula closure by vascular plug in a patient with post‐COVID‐19 myocardial infarction

Herein, we report a man with a huge coronary fistula connecting the left circumflex coronary artery to the right ventricle. During the follow‐up, the patient developed progressive symptoms of heart failure nonresponsive to medical treatment. Therefore, an endovascular closure with a vascular plug was successfully done for him. Transcatheter vascular plug occlusion can be considered as an alternative for closure of symptomatic high‐flow large coronary artery fistulas in patients with a high risk of surgery and chance of coil dislocation, embolization, or unavailability of proper coils.
