Pulmonary arteriovenous malformation (PAVM) is a probable cause of thromboembolic diseases such as acute myocardial infarction (MI); however, few cases have been reported. A woman in her early 40s developed acute-onset chest pain; an ECG showed ST-elevated MI. Emergency catheter angiography showed that the culprit lesion was a thrombus that was treated successfully with aspiration. She had a history of deep venous thrombosis and CT revealed PAVM. It was likely that the venous thrombus had moved into the coronary artery through the PAVM. Catheter embolisation of the PAVM was performed and she did not experience any other cardiac event until 6 months after embolisation.
