The Promote Quadra CRT-D is the industry’s first quadripolar pacing system, which offers physicians the ability to more effectively and efficiently manage the ever-changing pacing needs of patients with heart failure. It integrates multiple pacing configurations and features that enable physicians to optimise the system at implant and follow-up, as well as better manage common complications without having to surgically reposition the lead.
The Quartet left ventricular pacing lead, used as part of the Promote Quadra system, features four pacing electrodes on the left ventricular lead – enabling up to 10 pacing configurations. Multiple pacing configurations allow the physician to implant the lead in the most stable position, while still being able to select the most optimal pacing location. Having multiple pacing electrodes also provides physicians more options to optimise CRT performance, such as pacing around scar tissue in the heart, and avoiding common pacing complications.
“The Promote Quadra CRT-D gives me a greater number of less-invasive methods for managing my heart failure patients using CRT and reduces my patients’ risk of needing multiple surgical procedures. The Quartet lead also allows me more options for placing the pacing lead, without any compromises on handling characteristics,” said Wolfgang Kranig of Schüchtermann-Schiller’sche Kliniken in Bad Rothenfelde, Germany. “Because of the benefits this quadripolar technology offers without any significant tradeoffs, it should be considered a new standard of care for CRT.”
In addition to multiple pacing options, the Quartet pacing lead features other St Jude Medical technologies such as Optim insulation – a material that combines the biostability and flexibility of high-performance silicone rubber with the strength, tear resistance and abrasion resistance of polyurethane, to provide increased durability, flexibility and improved handling characteristics - and the S-curve design of the QuickFlex lead family, which increases stability.
