Inadvertent endocardial placement of a pacing lead in the left ventricle through the aortic valve is a rare complication with an unknown incidence because of inadequate reporting. Reported cases are usually the result of lead insertion via the subclavian artery. A possible but very unusual situation is endocardial lead insertion in the left ventricle after aortic arch perforation. We report the case of a 72-year-old woman in whom a screw-in pacing lead accidentally perforated the aortic arch and continued its way through the ascending aorta, aortic valve and left ventricle, after insertion through the left subclavian vein. We describe how this complication was diagnosed, the predisposing factors, the risks it carries and the ways in which devastating consequences have so far been avoided, as the patient refused any surgical intervention including lead removal.
