St. Jude Medical announced that clinical findings on quadripolar pacing will be presented at the 61st Annual Scientific Sessions of the American College of Cardiology (ACC, Chicago, March 24-27 2012).

According to St. Jude’s announcement, quadripolar pacing allows physicians the ability to use multisite left-ventricular (LV) pacing.  Studies that examined the role of multisite pacing in improving hemodynamics and reducing dyssynchrony as compared to traditional bi-ventricular pacing will be presented in the following two posters:

  1. Acute hemodynamic benefits of multisite left ventricular pacing in CRT recipients – This study found that in 13 patients receiving a CRT implant, all 13 patients demonstrated hemodynamic improvement as a result of multisite pacing configuration options.
  2. Multisite left ventricular pacing and acute mechanical dyssynchrony in heart failure patients – This study found that in 33 patients receiving a CRT implant, multisite pacing can reduce mechanical dyssynchrony beyond conventional bi-ventricular pacing, and may improve clinical response to CRT.
