NATICK, Mass., March 7 /PRNewswire-FirstCall/ -- Boston Scientific Corporation (NYSE: BSX) today announced the schedule of the Company's major events at the annual American College of Cardiology Scientific Session, which runs from March 11 to 14 in Atlanta, Georgia.

"The data we will present at ACC from our TAXUS clinical studies demonstrates the performance of the TAXUS Express2 paclitaxel-eluting stent system as an effective treatment in the most complex lesions and highest risk patients, including diabetics," said Paul LaViolette, Chief Operating Officer of Boston Scientific. "As the leader in drug-eluting stents, we continue to offer advanced deliverability and proven outcomes with our TAXUS stent systems. We expect our most recent clinical data will further reinforce that position."

  * TAXUS V ISR Results.  At 10:00 a.m., the Company will release nine-month
    results from the TAXUS V In-Stent Restenosis (ISR) clinical trial,
    which evaluates the TAXUS Express2 paclitaxel-eluting coronary stent
    system versus vascular brachytherapy for the treatment of bare metal
    stent in-stent restenosis.  The TAXUS V ISR trial is a prospective,
    randomized, open-label trial with a primary endpoint of target vessel
    revascularization (TVR) at nine months.  The trial has enrolled 396
    patients at 37 sites in the U.S.  The results will be presented by
    Gregg W. Stone, M.D., the study's Principal Investigator, at a podium
    session in Hall C3 of the Georgia World Congress Center.  The Company
    will also issue a press release at this time.  The TAXUS V ISR results

    presented by Charles A. Simonton III, M.D., chairman of the executive
    steering committee for the STENT registry, at a podium session in Hall
    C3 of the Georgia World Congress Center.  This large, independent,
    prospective, mulitcenter registry evaluates the comparative late
    clinical outcomes of paclitaxel- and sirolimus-eluting coronary stents
    among "real-world" cases and clinical situations, including diabetics
    and other high-risk patients.  With a planned enrollment of more than
    8,000 patients, the STENT registry is the largest study of its kind in
    the United States.

    M.D. and Patrick W. Serruys, M.D., Ph.D.  The event will include
    case-based presentations and interactive sessions on the latest
    clinical evidence and "real-world" registry data for drug-eluting
    stents in complex patients.  The Company will also host a reception
    prior to the symposium from 7:00 to 8:00 p.m. adjacent to the Grand
