Figure 2 Cross sections of 8-F silicone Riata single-coil (A) and dual-coil (B) high-voltage implantable cardioverter-defibrillator leads. The cables are coated in ethylene-tetrafluoroethylene, which are shown in blue, and the central coil pace-sense conductor with a stylet lumen is encased in a tube of polytetrafluoroethylene, which is shown in green. Arrows indicate location and direction of inside-out abrasion. Heart Rhythm 2012 9, 742-749DOI: (10.1016/j.hrthm.2011.12.019) Copyright © 2012 Heart Rhythm Society Terms and Conditions
Figure 3 Location of Riata and Riata ST insulation defects. Note that the proximal coil is not present in single-coil models, and defects in segment B will be in the lead body for single-coil models.
