Placement of a Defibrillation Lead in the Left Subclavian Vein from the Right Cephalic Vein.

This case report highlights the feasibility and stability of transvenous placement of a second defibrillation lead in the left subclavian vein from a right cephalic vein approach. This was undertaken in a right-sided implant of an active can cardioverter defibrillator to lower defibrillation thresholds that would have otherwise precluded implant. [ABSTRACT FROM AUTHOR]
