Permanent pacemaker implanted into patient’s left ventricle via subclavian artery by mistake: a case report

BACKGROUND Although various iatrogenic complications could be observed in the process of permanent pacemaker implantation, pacemaker electrode mistakenly implanted into left ventricle via subclavian artery and aortic valve has not been reported. CASE PRESENTATION Herein, we reported a 71-year-old woman with permanent pacemaker mistakenly implanted into the left ventricle. During the operation of permanent pacemaker implantation, puncture was performed on her subclavian artery by mistake, and then the pacemaker electrode was put into the cardiac apex of left ventricle via ascending aorta reversely. CONCLUSION The further operation could be conducted.
