Abstract:With the gradual expansion of indications for cardiac resynchronization therapy, more and more patients require coronary sinus(CS) lead extraction. The main reasons for lead extraction are infection and lead displacement. This paper mainly introduces extraction techniques including direct removal, intravascular retrograde traction, laser sheath, mechanical dilation sheath, spiral sheath and snare techniques. In addition, this paper also covers the removal of active and passive fixed CS lead, and complications of operation.
