More Options to Make Non-Response a Non-Issue

The Quadra Assura MP™ CRT-D brings MultiPoint™ Pacing, an exclusive Abbott technology, to cardiac resynchronization therapy defibrillators (CRT-Ds).

Overview

MultiPoint Pacing technology is designed to deliver multiple independent left ventricular (LV) pacing pulses from a single quadripolar lead to provide you with CRT options to change:

  • Pattern of depolarization
  • Engagement of areas around scar tissue
  • Hemodynamics
  • Resynchronization

The Quadra Assura MP CRT-D with Quartet™ quadripolar LV pacing lead, with its four pacing electrodes and 10 pacing vectors, provides more options and greater control in CRT response.
 

U.S. IDE Study: Importance of MPP™ Technology Programming1

The recent IDE study1 post-hoc subanalysis (n = 199) showed that wider cathode spacing and near-simultaneous intraventricular timing delays provide best MultiPoint Pacing technology response at 87 percent and “super-response” at 54 percent (52 patients).1
 

Additional International Clinical Data

This evidence builds on our quadripolar standard of care, which has offered you more options to pace at the preferred LV site, resulting in:

  • Improved CRT outcome2,3
  • Fewer surgical revisions4
  • Reduced need for lead repositioning at implant, leading to shorter procedure times and decreased fluoroscopic exposure5,6
  • More basal pacing opportunities without compromising lead stability7,8



Advanced Features and Benefits

Now MRI Ready

The Quadra Assura MP CRT-D is MR conditional when used with specific leads and lead lengths, and allows full-body, 1.5T MRI scans that meet certain scan conditions.*

  • Meets industry-standard MRI testing requirements
  • Capable of full body 1.5T MRI imaging scans

Designed to Optimize Tissue Selection

The Quadra Assura MP CRT-D offers Auto VectSelect Quartet™ Test that:

  • Automatically identifies tissue sites with the latest activation via RV-LV conduction delays measurements
  • Performs threshold testing, assesses LVCap™ Confirm applicability and allows marking of PNS

Pacing at the tissue site of latest activation improves:

  • Acute hemodynamic response9
  • Reverse remodeling10
  • Quality of life10

Enhanced Programming Options
  • SyncAV™ CRT technology automatically adjusts pacing based on real-time changes in a patient's cardiac condition.
  • Antitachycardia pacing (ATP) while charging and prior to charging in the VF zone further extends the programming options for terminating tachyarrhythmias without a high-voltage shock.
  • SenseAbility™ feature provides flexibility to fine-tune programming around T-wave oversensing without decreasing sensitivity.

Additional Monitoring and Safety Features
  • ShockGuard™ technology with DecisionTx™ programming
  • SecureSense™ RV lead noise discrimination
  • Far Field MD™ morphology discrimination
  • DeFT Response™ technology
  • CorVue™ congestion monitoring feature
  • QuickOpt™ timing cycle optimization

Building Comprehensive Heart Failure Management

The Quadra Assura MP™ CRT-D is one of our heart failure management therapies. Our vision is to transform the treatment of heart failure by designing technology that delivers excellent clinical outcomes and improves workflow and efficiency. Read more about our approach to heart failure management.
