January 3, 2018 — Abbott announced U.S. Food and Drug Administration (FDA) approval for magnetic resonance (MR)-conditional labeling for the Quadra Assura MP cardiac resynchronization therapy defibrillator (CRT-D) and Fortify Assura implantable cardioverter defibrillator (ICD). The approvals follow recent MR-conditional labeling approvals for the Assurity MRI pacemaker, Ellipse ICD and associated MRI-compatible leads, and further expand Abbott's portfolio of MRI-ready devices for patients indicated for ICDs and/or CRT-D devices who may need an MRI in the future.
Physicians utilize ICDs to restore normal heart rhythms in patients at risk for experiencing potentially life-threatening heart rhythms; they implant CRT-D devices to help the lower chambers of the heart beat in rhythm in patients battling progressive congestive heart failure and improve blood flow throughout the body. For some patients, the potential need for a future MRI has made MR-conditional labeling important as physicians assess therapies and device options. As a result, Abbott has done extensive testing to demonstrate that these devices are safe in the most commonly-used MRI scanners.
In addition to MRI compatibility, Abbott's Fortify Assura ICD and Quadra Assura MP CRT-D also include the company's suite of TailoredTherapy features, which are designed to provide physicians additional flexibility and control in how they deliver therapy to treat their patient's cardiac arrhythmias and congestive heart failure, even as their patient's therapy needs change over time. With the TailoredTherapy feature set, the Fortify Assura ICD and Quadra Assura MP CRT-D help protect against the delivery of unnecessary therapy and continuously evaluate the condition of a lead to consistently deliver appropriate therapy. Combined with MRI compatibility, these features offer physicians additional options to leverage when managing patient care.
The Quadra Assura MP CRT-D also offers Abbott's proprietary MultiPoint Pacing and SyncAV technology to provide additional options for CRT patients who are not responsive to traditional cardiac resynchronization therapy. With MultiPoint Pacing, Abbott allows physicians to "individualize" cardiac resynchronization therapy and shift their patient's treatment options from a single point of pacing to multiple options to better deliver therapy where needed. Abbott's SynvAV software allows a CRT device to detect real-time changes in a patient's cardiac condition and adjust therapy accordingly.
As with all Abbott cardiac rhythm management devices, all therapy data captured by the Fortify Assura and Quadra Assura MP devices can be directly, securely and wirelessly sent to a patient's doctor through the Merlin.netTM Patient Care Network. This communication allows physicians to remotely monitor their patient's therapy and assess any need for intervention.
