Abstract
Background: Coronary artery fistula (CAF) is an abnormal communication between the
termination of a coronary artery or its branches and a cardiac chamber, a great vessel or other vascular
structure. Symptomatic patients with large CAF should undergo surgical or percutanous closure
of the fistula at the drainage site while still the debate on closing asymptomatic CAF and reopening
symptomatic occluded CAF is ongoing.
Case Summary: We are reporting a 30-year-old male patient with no previous medical history presented
as non-ST segment elevation myocardial Infarction. Coronary angiography showed an entirely
thrombosed ectatic circumflex artery with a suspicion of thrombosed coronary arterial fistula.
In view of the ongoing ischemia in the setting of acute coronary syndrome; we tried to open percutaneously
but all efforts were to no avail.
Discussion: In this case report, we are sharing our experience in the management of this challenging
case in view of the rarity of such peculiar clinical condition and the unfavourable presentation
along with the lack of clear-cut Guideline and Consensus whether to/not to open such huge and
immensely thrombosed symptomatic coronary artery fistula as well as the dilemma of choosing the
best long-term medical treatment between antiplatelets vs anticoagulants in such young patient.
