Avulsion of a tricuspid valve leaflet during traction on an infected, entrapped endocardial pacemaker electrode: The role of electrode design

摘要: Endocardial pacemaker electrodes rely in part upon endocardial fixation proximal to the electrode tip prevent ejection of from ventricular apex. Fixation these superior vena cava and tricuspid valve, particular, has been reported. Infection necessitates their removal. This report concerns avulsion a valve leaflet during traction on an infected electrode. With availability new methods apical fixation, utilization sheathing materials which discourage would increase safety removal under circumstances reported herein.
