Coronary perforation is the most feared and lethal complication in the catheterization laboratories. Perforation incidence is reported to be between 0,2 - 0,6%. Sixty nine year-old patient with a typical angina pectoris and having a positive effort test was admitted to the catheter laboratory for coronary angiography. In the coronary angiography, Biomime stent was deployed with nominal pressure to the mid segment of the left anterior descending (LAD) artery which was found to have a 80% stenosis. In order to obtain optimal expansion, postdilatation was performed with a powerline balloon. After postdilatation, Ellis grade III perforation was developed. Bleeding control was achieved with implantation of a 3,0×19 mm graft stent to the perforation site. In the echocardiographic investigations, the patient did not exhibit any pericardial fluid and tamponade findings so the patient was discharged after 48 hours.
