title: [Video-assisted thoracoscopic implantation of left ventricular pacing lead;usefulness of CARTO system;report of a case].
abstract: A 70-year-old man, with a history of broad anterior myocardial infarction and repeated several hospitalizations due to heart failure, was referred to our institution for cardiac resynchronization therapy. However, as intravenous implantation of the left ventricular pacemaker lead was not possible, the patient underwent video-assisted thoracoscopic (VAT) implantation. We noted broad myocardial scarring and patent grafts, along with previously bypassed left internal thoracic artery( LITA)-left anterior descending artery (LAD) and right internal thoracic artery (RITA)-D1;thus, the area suitable for implantation of the left ventricule (LV) pacemaker was believed to be restricted. Therefore, we decided to determine the viable myocardial area by using CARTO system and identify the appropriate access port positions for the subsequent VAT surgery. After the LV pacemaker lead was implanted, the recorded pacing threshold was found to be <1.2 V at 0.5 ms. Thus, the CARTO system might be useful to preoperatively identify an area suitable for surgical implantation of a LV pacemaker lead in patients with ischemic cardiomyopathy.
