Abstract

AbstractCoronary artery perforation (CAP) is a rare but lethal complication of percutaneous coronary interventions (PCIs), and its incidence has been increasing with advances in PCI techniques. Delayed CAP presents a highly challenging complication, as it occurs 30 min−9 days after intervention, making subsequent diagnosis and treatment difficult. We present the case of a 63‐year‐old male patient who underwent PCI for an obtuse marginalis II because of posterior wall myocardial infarction. Following 4 days of uneventful postoperative stay, the patient developed angina pectoris and hypotension 4 h after reinitiation of anticoagulant therapy with edoxaban. Angiography revealed distal vessel perforation from a side branch of the obtuse marginalis II. The vessel was occluded using autologous fat embolization via a microcatheter, resulting in complete sealing of the perforation. After discharge, 4 weeks after the infarction, the patient started rehabilitation therapy. Distal vessel perforations are typically caused by wire damage. In our case, we also suspected distal wire perforation, which was initially not recognized possibly due to distal occlusion through the thrombotic material. The temporal correlation between the re‐initiation of anticoagulant therapy and the occurrence of cardiac tamponade suggests that the thrombotic material was resolved due to the former. The management of delayed CAP does not differ from that of CAP; thus, this rare complication should be considered even days after PCI as it could prove lethal if not recognized early.
