Antidromic snare technique for re-implantation of a coronary sinus lead into the same cardiac vein after transvenous lead extraction: a case report.

Antegrade re-implantation of CS lead may not be possible after extracting CS leads with long dwell times, possibly due to extraction-induced vessel occlusion. If the occluded vessel is the only proper vessel for CS lead re-implantation, the anti-dromic snare technique could be a safe and effective bail-out strategy.
