It may be underestimated and underreported because of a possible asymptomatic course. A 12-lead electrocardiogram is important to confirm proper placement. Case presentation We report a case of a 60-year-old Caucasian man with a malpositioned transvenous permanent pacing lead into the left ventricle via a patent foramen ovale that was not suspected during implantation and went undiagnosed for two years without complications. The patient remained asymptomatic as he was being treated with oral anticoagulation therapy for atrial fibrillation. The decision was made to leave the pacing lead in place and continue lifelong warfarin therapy. Conclusions Inadvertent insertion of pacing wires into the left ventricle is a potentially dangerous complication that may happen under fluoroscopic guidance and may be overlooked by routine pacemaker interrogation. It is advisable to obtain a 12-lead electrocardiogram during or immediately after transvenous pacemaker implantation rather than use a routine pacemaker interrogation or a limited electrocardiogram. Introduction Implantation of transvenous pacing leads and implantable cardioverter-defibrillator wires is the most common surgery involving the heart 1 . It is estimated that more than 100 000 implantable cardioverter-defibrillator and more than 200 000 permanent cardiac pacemaker implantations are performed in the USA annually 2 . This procedure is performed by cardiologists cardi-othoracic
