leads of any kind

ST. PAUL, Minn. & BARCELONA, Spain -- (Business Wire)
St. Jude Medical, Inc. (NYSE:STJ), a global medical device company,
today announced results from a large-scale, clinical study concluding
that the St.
Jude Medical Quartet™ left-ventricular (LV) quadripolar lead
provides more options to effectively manage common pacing complications
compared to systems with bipolar leads.
The MORE-CRT data, More Options
available with a quadripolar LV lead pRovidE
in clinic solutions to CRT challenges, was
presented during a hot line late-breaking session at the European
Society of Cardiology Congress 2014 (ESC 2014). Results showed that
complications occurred less frequently and were managed more efficiently
in patients who received the Quartet lead than in patients who received
bipolar electrode leads.
“The risk of LV lead-related events was more than 40 percent lower in
patients implanted with a Quartet CRT-D system relative to patients
implanted with a bipolar CRT-D system,” said Prof. Giuseppe Boriani,
M.D., Ph.D., of the Institute of Cardiology, University of Bologna,
Italy, and the MORE-CRT steering committee chairman. “The overall
freedom from intraoperative and post-operative LV lead-related events
was significantly higher in quadripolar CRT group versus bipolar CRT
group. These data are very important in deciding how we treat our
patients going forward.”
More than 60 centers from 13 countries participated in this first
randomized, large-scale clinical study of more than 1,000 patients
comparing the St. Jude Medical Quartet lead to bipolar LV leads
(one-third of bipolar leads were St. Jude Medical and two-thirds were
non-St. Jude Medical). The primary endpoint of the study was freedom
from intra- and post-operative LV lead-related events at six months.
The Quartet lead was associated with a statistically significant
increase in freedom from combined LV lead-related events — 85.97 percent
in patients implanted with a Quartet lead compared to 76.86 percent in
patients implanted with a bipolar LV lead.
“The design of St. Jude Medical’s Quartet quadripolar technology is
unique,” said Dr. Mark D. Carlson, chief medical officer and vice
president of global clinical affairs for St. Jude Medical. “The MORE-CRT
study confirms that our quadripolar system has set the standard for the
quadripolar pacing industry and the study is a strong addition to the
more than 100 publications showing our technology improves outcomes and
quality while reducing costs.”
The quadripolar pacing technology is important because failed implant
rates in heart failure (HF) patients receiving a cardiac
resynchronization therapy (CRT) system are significantly higher with
bipolar LV pacing leads due to anatomy (creating lead stability
problems), phrenic nerve stimulation (PNS) or poor electrical
measurements.
Leading Quadripolar Technology and Clinical Evidence
Additional data on the first-to-market MultiPoint pacing system
presented during ESC 2014 includes 12 month results from the St. Jude
Medical MultiPoint™ Pacing (MPP) clinical study. Twelve month results,
consistent with the three month data, indicates a 19 percent increase in
the number of patients responding to CRT compared to the
standard-of-care, biventricular pacing. CRT response in the MultiPoint
pacing study was quantified as a greater than 15 percent reduction in
End Systolic Volume (ESV) and an increase in ejection fraction (EF) to
baseline, two commonly used but rigorous criteria for determining CRT
response. Quadra Assura MP™ CRT-D is an investigational device in the
U.S. and is not commercially approved in the U.S.
Data presented at the 2014 Heart Rhythm Society’s Annual Scientific
Sessions in May, Reduced
Mortality with Quadripolar versus Bipolar Left Ventricular Leads in
Cardiac Resynchronization Therapy, demonstrates an 18 percent
reduction in mortality, as well as other improved clinical outcomes and
better cost utilization with St. Jude Medical’s quadripolar technology.
The large and growing body of clinical evidence combined with a strong
product pipeline, including next-generation MultiPoint pacing
(investigational device in the U.S.), makes St. Jude Medical’s
quadripolar system the standard of care in improving the management of
CRT.
Data looking at Hospitalization
Rates and Associated Cost Analysis of Quadripolar versus Bipolar CRT-D:
a comparative analysis of a single-center prospective Italian registry,
also presented at HRS 2014, found that the use of quadripolar leads
reduced the number of hospitalizations by 53 percent when compared to
the non-quadripolar leads. This hospitalization rate reduction
translated into a statistically significant 62 percent reduction in
overall costs for both health care systems and patients.
