[Coronary artery perforation after directional coronary atherectomy (DCA)].
Directional coronary atherectomy (DCA) was performed on a 51-year-old man with unstable angina due to a 90% stenosis of the proximal side of the left anterior descending artery (LAD). A coronary angiography after the DCA showed the coronary artery perforation communicating with the pericardial space. He suffered cardiac tamponade and cardiogenic shock, and was taken to the emergent surgical intervention. The both side of the perforation was ligated to control active bleeding and coronary artery bypass grafting to the distal portion of the LAD was performed. It is stated that the incidence of tamponade resulting from vessel perforation after DCA is extremely rare.
