Abstract

A 41-year-old man underwent implantation of a right-sided implantable cardioverter defibrillator after removal of an infected left-sided system. Defibrillation threshold (DFT) testing on the right-sided system failed to convert ventricular fibrillation at maximum device output (35 J) compared with a DFT of less than 15 J on the previous left-sided system. A single-coil lead was selectively placed into the hemiazygous vein, which courses leftward of the spine in a posterior-anterior projection, resulting in an improved shocking vector and reduction in DFTs to less than 25 J.
