ST. PAUL, Minn.--(BUSINESS WIRE)--St. Jude Medical, Inc. (NYSE:STJ), a global medical device company, recently received U.S. Food and Drug Administration (FDA) approval of the company’s proprietary, first-to-market MultiPoint™ Pacing technology and today announced the U.S. launch and first U.S. implants of the Quadra Assura MP™ cardiac resynchronization therapy defibrillator (CRT-D). MultiPoint Pacing technology is a revolutionary approach designed for CRT patients who are not responsive to other pacing options.

The first implant took place at Saint Francis Hospital in Hartford, Conn. Speaking about the opportunity, Dr. Neal Lippman, electrophysiologist with Arrhythmia Consultants of Connecticut at Saint Francis said, “We are now able to offer St. Jude Medical’s new MultiPoint Pacing technology for our patients whose heart failure condition is difficult to manage. It is important for us to have this option to individualize patient care and help improve response to therapy.”

Despite the improvements in patient outcomes seen with quadripolar CRT technology, a small, but important group of patients do not respond optimally to the therapy. Importantly, these “non-responders” to CRT cannot be identified at the time of implant and how effective the therapy will be in addressing an individual patient’s heart failure symptoms can be unpredictable. MultiPoint Pacing technology offers physicians a new set of tools that allow for individualized patient therapy with the goal of optimizing their response to CRT.
“St. Jude Medical developed and established a new standard of care for CRT with quadripolar pacing. We are excited to bring the next-generation MultiPoint Pacing technology to market, giving physicians additional options to improve patient response,” said Dr. Mark D. Carlson, vice president of global clinical affairs and chief medical officer at St. Jude Medical.

Cardiac resynchronization therapy includes a lead (Quartet™ Quadripolar LV Lead) placed on the lower left chamber of the heart (ventricle). The left ventricle pumps oxygenated blood from the heart out to the rest of the body. MultiPoint Pacing technology is designed to deliver electrical pulses to multiple locations on the Quartet lead to make the heart’s lower chambers pump in a more coordinated way to mirror the natural contractions of a healthy heart.

According to the American Heart Association, CRT can improve the heart’s efficiency at pumping blood to the body and can lessen symptoms of heart failure, including shortness of breath. However, even with effective placement of the leads around the heart, therapy can be unpredictable and ineffective for some patients. MultiPoint Pacing technology allows physicians to program the device to stimulate more left-ventricular tissue at one time by pacing at multiple locations in the heart, more similar to the natural electrical behavior of the heart. Over 60 abstracts and publications demonstrate that this increases the number of patients who benefit from this type of therapy (CRT).
