Lower-Profile SAPIEN XT Transcatheter Heart Valve Associated With Improved Procedural Outcomes

Lower-Profile SAPIEN XT Transcatheter Heart Valve Associated With Improved 
Procedural Outcomes 
Preliminary Results From Inoperable Cohort of The PARTNER II Trial
Presented at ACC 2013 
SAN FRANCISCO, CA -- (Marketwire) -- 03/10/13 --   Edwards
Lifesciences Corporation (NYSE: EW), the global leader in the science
of heart valves and hemodynamic monitoring, announced that
preliminary results from The PARTNER II Trial demonstrated similar
one-year outcomes in mortality and major clinical events between the
Edwards SAPIEN XT transcatheter aortic valve and the Edwards SAPIEN
valve, yet fewer vascular events with the lower-profile SAPIEN XT
valve. These data from The PARTNER II Trial studying transcatheter
aortic valve replacement (TAVR) in inoperable patients with severe,
symptomatic aortic stenosis were presented today as a late-breaking
clinical trial at the American College of Cardiology's (ACC) 62nd
Annual Scientific Session in San Francisco.  
"We are very pleased to see improved outcomes in both the SAPIEN and
SAPIEN XT patients, as compared to results from earlier trials," said
Larry L. Wood, Edwards' corporate vice president, transcatheter heart
valves. "The SAPIEN XT valve was designed to reduce complications of
the TAVR procedure, and we believe this has been demonstrated by
today's results. Edwards is proud to lead the advancement of
cutting-edge innovations for these high-risk patients, supported by
rigorous clinical evidence." 
The PARTNER II Trial enrolled 560 patients deemed inoperable for
traditional open-heart surgery at 28 hospitals in the United States
between April 2011 and February 2012. Patients were randomized to
receive one of the two Edwards transcatheter aortic heart valves: 276
received the SAPIEN valve, and 284 received the SAPIEN XT valve.  
The FDA approved the SAPIEN valve in November 2011 for the treatment
of inoperable patients, and expanded the indication to high-risk
surgical patients in October 2012. The SAPIEN XT valve is an
investigational device not yet available commercially in the United
Edwards anticipates submitting data from the inoperable cohort
(Cohort B) of The PARTNER II Trial to the United States Food and Drug
Administration (FDA) in the second quarter. The company expects to
complete enrollment in the intermediate risk cohort (Cohort A) of The
PARTNER II Trial mid-year.

Background Information on The PARTNER Trial, Inoperable Cohort (Cohort
The PARTNER Trial studied 358 patients with severe, symptomatic
aortic stenosis deemed inoperable for traditional open-heart surgery,
and enrolled between April 2007 and March 2009. Patients were evenly
randomized to receive either the Edwards SAPIEN valve or standard
therapy. Please note that the results from The PARTNER Trial and The
PARTNER II Trial are not directly comparable.
