[Migration of a Temporary Epicardial Pacing Lead into the Vascular Graft].

ABSTRACT

A 48-year-old man was refered to our hospital for the treatment of bicusp aortic valve and severe aortic regurgitation. He underwent Bentall procedure (SJM 25mm+HemashieldØ 28 mm composite graft). Temporary epicardial pacing lead( TPL) was placed on the right ventricle at the opetation, and was cut on his skin surface prior to discharge because of difficulty in traction removal. After 15 years from operation, follow up computered tomography and echocardiography showed migration of 2 retaining TPLs extending from vascular graft of ascending aorta to the right innominate artery. We performed Redo-median sternotomy and removed the TPLs. This is the 1st reported case of a migrated temporary pacing lead into the vascular graft of ascending aorta under noninfectious conditions.
