Key result
Non-thoracotomy extraction of chronically implanted leads was successful in 6 of 9 sheep, with major complications including great coronary vein laceration and cardiac tamponade.

Caution for CS/GCV laceration during chronic lead extraction; leaves open clinical translation to atrial defibrillators.
What are the post-mortem changes and clinical success rates of non-thoracotomy lead extraction from the ovine coronary sinus and great cardiac vein?
Non-thoracotomy extraction of chronically implanted leads from the coronary sinus and great cardiac vein carries a high risk of severe vascular laceration and tamponade, necessitating surgical backup.
Tacker et al. (1998) studied Chronically implanted leads for atrial implantable defibrillation (n=9). Non-thoracotomy extraction of leads was evaluated on Clinical success of extraction. Non-thoracotomy extraction of chronically implanted leads was successful in 6 of 9 sheep, with major complications including great coronary vein laceration and cardiac tamponade.
