Lead-Sparing Tricuspid Valve Repair Damaged by Pacemaker Lead

Permanent pacemaker lead may damage the tricuspid valve in various ways, causing severe tricuspid valve regurgitation. The perforation of posterior papillary muscle is an uncommon complication caused by the lead. We describe a lead-sparing tricuspid valve repair in which the lead extraction was not an option. The papillary muscle containing the lead was fully mobilized to release the adherent leaflets. The repair was completed by commissuroplasty as well as ring annuloplasty, leaving the lead inside the implanted ring. (C) 2017 by The Society of Thoracic Surgeons
