Medtronic (NYSE: MDT) announced it has received United States Food and Drug Administration (FDA) approval for the Attain Performa Model 4298 quadripolar lead, and the Viva Quad XT and Viva Quad S cardiac resynchronization therapy defibrillators (CRT-D). The quadripolar lead and devices will be broadly available to physicians in mid-September.
With 16 pacing configurations and shorter spacing between the two center electrodes, the Attain Performa Model 4298 left-heart lead provides additional options for physicians to treat different patient anatomies. The new quadripolar lead reduces the incidence of phrenic nerve stimulation (PNS)1, a potential side effect that results in muscle twitching, hiccups or shortness of breath. The Viva Quad XT device is equipped with the proprietary AdaptivCRT feature, which preserves normal heart rhythms and automatically adjusts to patients' needs to customize therapy. The system includes VectorExpress(TM) technology, which reduces lead programming time to two minutes2 by providing physicians with clinically actionable information to help them select optimal pacing configurations for each patient.
Quadripolar leads (leads with four electrodes) help physicians optimize cardiac resynchronization therapy delivery. The Attain Performa lead addresses the clinical challenges that can compromise lead position, offering implanting physicians more options to maintain lead position and optimize CRT therapy3. The Model 4298 lead has a canted shape, and steroid on all four electrodes for lower pacing thresholds4,5.
"Compared to conventional leads, the additional pacing configurations offered by this system provide implanting physicians more options to optimize CRT delivery, which results in better patient care. Likewise, the narrow-spaced bipole helps avoid phrenic nerve capture," said George H. Crossley, M.D., F.A.C.C., F.H.R.S., associate professor, Vanderbilt Heart and Vascular Institute, in Nashville, Tenn.
