A shocking lead in the coronary sinus

Placement of leads into the coronary sinus (CS) is now routinely used for cardiac resynchronization therapy. However, the CS can also be used for the placement of defibrillator shock leads. There is evidence demonstrating that CS leads in situ for the short and medium term can be successfully removed utilizing percutaneous methods. We report a case of CS laser lead extraction where a defibrillator lead had been in place for almost 10 years.
