[Right ventricular perforation by screw-in lead after permanent pacemaker implantation: a case report].

A 93-year-old man received a permanent implanted pacemaker(VVI mode) to treat completed atrioventricular block in our hospital. However, pacing failure appeared 4 days later. Computed tomography showed right ventricular perforation by the screw-in lead. There was no evidence of cardiac tamponade or symptoms, so we inserted another lead into the right ventricular outflow tract without removing the first lead. This patient still has the pacing lead that perforated the right ventricle, so careful observation will be needed even after discharge.
