We report a novel complication that arose while treating a 54 year old man with acute inferior ST elevation segment myocardial infarction. It was decided to perform thrombus aspiration prior to balloon angioplasty. However, after aggressive maneuvers to cross the tight lesion in order to suck the distal thrombus, a novel complication was encountered. The Thrombus Aspiration Catheter (TAC) got stuck in the coronary artery. When the whole apparatus was pulled out, it was realized that the guidewire cut the main shaft of TAC and catheter got twisted over the wire. To the best of our knowledge, this is the first report of a complication of this type.
