  • Abstract
  • Look Inside

We encountered a 59-year-old male patient suffering from left main coronary artery (LMT) stenosis follow-ing directional coronary atherectomy (DCA). He was admitted to our hospital because of acute myocardial infarction. After successful treatment with per-cutaneous transluminal coronary recanalization and angioplasty for the right coronary artery, DCA was carried out for the left anterior descending artery (LAD). 89 days later, he received DCA for re-stenosis of LAD. About 2 months after the second DCA, he complained of chest pain caused by LMT stenosis. Intima injury caused by the guiding catheter during the DCA procedure seems to be the main reason for LMT stenosis following DCA. More delicate catheter han-dling and careful follow up are necessary to avoid an accident caused by DCA such as happened in our case.
