REPRISE II Data Honored as Best Abstract 2013 at PCR London Valves Course

Boston Scientific Corporation (NYSE: BSX) reported favorable six-month results
from the first 60 patients enrolled in the REPRISE II clinical trial
evaluating the safety and performance of the Lotus™ Valve System in
symptomatic patients with severe aortic stenosis considered at high risk for
surgical valve replacement. 

The data, which were presented today at PCR London Valves and formally
received the honor of Best Abstract 2013, demonstrated excellent results with
no new valve-related adverse events between 30 days and six months.
Additionally, there were no cases of moderate or severe paravalvular
regurgitation in any patient at six months.

Six-month results:

  *Excellent hemodynamic results continue to be observed at six months as
    demonstrated by mean aortic valve pressure gradient of 12.1 ± 5.0 mmHg and
    mean aortic valve area of 1.8 ± 0.5 cm ^2 .
  *Independent core lab assessment of paravalvular aortic regurgitation
    showed 76.1 percent of patients presenting with no paravalvular
    regurgitation and no cases of moderate or severe regurgitation.
  *There were no new valve-related adverse events recorded between 30 days
    and six months.
  *The NYHA classification data demonstrated a significant improvement in
    heart failure symptoms at six months compared to baseline.

"The Lotus Valve System provides the operator with superb control allowing
precise positioning and accurate deployment," said Professor Ian Meredith,
director of MonashHeart at Monash Medical Centre in Melbourne, Australia, and
principal investigator of the REPRISE II trial. "The results from the first 60
patients of the REPRISE II trial are very impressive, especially with no
patients presenting with moderate or severe paravalvular regurgitation at six

The Lotus Valve System is the first transcatheter aortic valve replacement
(TAVR) device of its kind with an Adaptive™ Seal that is designed to minimize
aortic regurgitation (leaking) around the valve, a proven predictor of
mortality, and is both fully repositionable and retrievable prior to release.

Boston Scientific expects to release additional REPRISE II data in late
October at the TCT (Transcatheter Cardiovascular Therapeutics) conference in
San Francisco.

"The latest results from REPRISE II underscore the promising and unique
technology behind the Lotus Valve System, demonstrating how the Lotus Valve
System can offer a new treatment alternative for patients with severe aortic
valve disease," said Keith Dawkins, M.D., global chief medical officer, Boston
Scientific."These features help to simplify the implantation procedure and
may lead to improved clinical outcomes."

available for sale. To view the Multimedia News Release including videos,

The results of the REPRISE clinical trial program are expected to be used to
support CE Mark and other international regulatory approvals.


REPRISE II is an ongoing prospective, single-arm study that has completed
enrollment of 120 patients at 14 sites in Australia, France, Germany and the
United Kingdom. All patients had severe symptomatic aortic stenosis and were
considered at high risk for surgical valve replacement. An additional 130
patients are expected to be enrolled at a total of 20 sites in Australia and
Europe in an extension of REPRISE II.
