The role of cardiac surgeon in transvenous lead extraction: Experience from 3462 procedures

Introduction: The professional society guidelines recommend that transvenous lead extraction (TLE) operating teams collaborate closely with cardiac surgeons in the management of life-threatening complications.

Methods: We assessed the role of cardiac surgeons participating in 3462 TLE procedures at a high-volume center between 2006 and 2021. The roles for cardiac surgery in TLE can be categorized into five areas: emergency surgical interventions for the management of cardiac laceration and severe bleeding (1.184%), cardiac surgery complementing partially successful TLE or vegetation removal (0.693%), delayed surgical treatment of TLE-related tricuspid valve dysfunction (0.751%), epicardial pacemaker implantation through sternotomy during emergency, complementing or delayed surgical interventions (0.607%), and delayed epicardial lead implantation (0.491%).

Results: Isolated damage to the wall of the right atrium was the most common cause of cardiac tamponade (53.66% of emergency surgeries) followed by injury to the right ventricle and vena cava (both 7.317%).

Conclusions: Emergency cardiac surgery for the management of severe hemorrhagic complications is still the most common treatment option. The remaining areas include surgery complementing partially successful TLE: repair of tricuspid valve or epicardial ventricular lead placement to achieve permanent cardiac resynchronization. The experience at a single high-volume TLE center indicates the necessity of close collaboration with the cardiac surgeons whose roles appear broader than the mere surgical standby. Mortality in patients who survived cardiac surgery during TLE does not differ from the survival of other patients after TLE without complications requiring surgical intervention.
