Inadvertent implantation of pacemaker lead in the left ventricle: kill two birds with one stone

We report an asymptomatic patient in whom the intravenous pacemaker (PM) lead was inadvertently implanted in LV through the perforated interventricular septum. He had no embolic events during the last 9 years after the implantation. Possible explanation of the uncomplicated follow-up period is that the patient had been taking warfarin because of mechanical mitral valve prosthesis.
