BACKGROUND : Coronavirus disease 2019 (COVID-19) is associated with hypercoagulability and a high rate of thrombosis. Few cases of coronary stent thrombosis associated with COVID-19 have been reported. CASE SUMMARY : In this report, we describe the case of a 65-year-old man with a history of coronary artery disease (CAD) who was admitted following an out-of-hospital cardiac arrest related to an ST-segment elevation myocardial infarction revealing a very late dual coronary stent thrombosis of the left anterior descending and posterior descending arteries. Ten days prior to admission, he was diagnosed with COVID-19 pneumonia and treated with dexamethasone, which led to rapid clinical improvement. After resuscitation, coronary angiography revealed an acute thrombotic occlusion in the two previous drug-eluting stents (implanted in 2010 and 2018), with a high thrombus burden. He was successfully treated by percutaneous coronary intervention. The patient did not present any further complications during his hospital stay and was transferred to a cardiac rehabilitation centre. DISCUSSION : Dual stent thrombosis is an exceptional event highlighting the high procoagulant state promoted by coronavirus 19. This case suggests that strengthening of antithrombotic therapy in CAD patients presenting with COVID-19 should be discussed.
