Abstract
Coronary artery injury is a particularly rare complication of pacemaker implantation. Herein, we reported the case of a 76-year-old woman with sick sinus syndrome undergoing permanent pacemaker implantation who presented with chest pain a day after the procedure. During angiography, a pacemaker lead screwed into the left anterior descending coronary artery was found. The coronary artery was covered by a stent and the lead position was corrected. Based on the published research, the majority of right ventricular pacemaker leads implanted on the septum are indeed implanted on the anteroseptal junction. Since, the left anterior descending coronary artery covers this site, the risk of artery injury is higher.
