We describe a new technique for removing distal emboli that became visible on angiography during percutaneous coronary intervention for acute myocardial infarction. Three patients presented with distal embolization as a filling defect with an abrupt cut-off in 1 of the peripheral coronary vessels of the infarct-related coronary artery. After a failed attempt to retrieve the thrombus with a conventional aspiration catheter, the thrombus was trapped at the tip of a microcatheter by aspiration and was successfully retrieved. This procedure can achieve prompt restoration of distal coronary flow.
