Cryptogenic left main thrombosis: Successful mechanical clot retrieval with a self‐expanding trapping device

We present the case of a 52‐year‐old male with ST‐segment elevation myocardial infarction due to a spontaneous large left main thrombosis, without any angiographic evidence for coronary artery disease. After multiple unsuccessful attempts of thrombaspiration the large clot was mechanically retrieved by a flow restoration device that was primarily made for intracranial interventions. Intravascular ultrasound revealed marginal lumen narrowing after the intervention, but the final coronary angiogram showed a patent left main and there was no relevant stenosis remaining. © 2013 Wiley Periodicals, Inc.
