The 25th Annual TCT Conference will be held in San Francisco, October 27-Nov 1, 2013
October 19, 2013 -- Medtronic, Inc. (NYSE: MDT) has announced a number of updates and presentations that will be made at the upcoming Transcatheter Cardiovascular Therapeutics (TCT) meeting in San Francisco, the largest gathering of interventional cardiologists and related healthcare professionals in the U.S. This year marks the 25th annual TCT.

Perhaps the most anticipated data for Medtronic will be from the first U.S.-based CoreValve trials of a self-expanding transcatheter heart valve in patients suffering from severe aortic stenosis. Currently the only system approved for use by the FDA is the first generation Sapien system, manufactured by Edwards. Both the Sapien and CoreValve have been available in Europe for several years and the numbers of patients being treated with this non-surgical approach to aortic valve replacement has been growing steadily each year.

Another hot topic will be renal denervation (RDN), a new method of treating hypertensive patients who do not adequately respond to medications. No RDN device is currently approved for use in the U.S. (several are in Europe) but Medtronic's Symplicity clinical trial program in the U.S. started early on and, if successful, will result in Medtronic offering the first such device approved by the F.D.A.

Finally, the ongoing topic of drug-eluting stents will see more information presented about optimal length of dual antiplatelet therapy as well as a new DES "match-up." Dr. Fausto Feres of Brazil will present the results of the OPTIMIZE study in which patients receiving the Endeavor zotarolimus-eluting stent discontinued DAPT at either 3 months or 12 months. If there are no safety or efficacy differences in these groups, the OPTIMIZE trial will add to the evidence that, at least with some second and third generation drug-eluting stents, a full year of DAPT may not be necessary, thus reducing costs and bleeding risks. For more information on the OPTIMIZE study, read Angioplasty.Org's interview with Dr. Fausto Feres.

A second major late-breaking clinical trial involving Medtronic stents will be the DUTCH PEERS (a.k.a. TWENTE II). The original TWENTE trial compared Medtronic's Resolute stent with Abbott's XIENCE and showed no difference in outcomes between the two (this was last measured at two years). On Thursday a new trial will be presented by the same Dutch research team, comparing Medtronic's Resolute Integrity with Boston Scientific's Promus Element -- both so-called third generation drug-eluting stents.

Medtronic to Unveil CoreValve U.S. Pivotal Trial Results at TCT 2013
Late Breaking Clinical Trial Features the First U.S. Data of Novel Self-Expanding Transcatheter Valve at Premier Interventional Cardiology Meeting
Other Late-Breakers Feature New Clinical Data on Endeavor and Resolute Drug-Eluting Stents; Three Year Results of Symplicity HTN-2 Study to be Presented

October 17, 2013 -- Minneapolis -- Medtronic, Inc. (NYSE: MDT) today announced its schedule of notable sessions that will be presented at the 25th Annual Transcatheter Cardiovascular Therapeutics (TCT) Symposium in San Francisco, including the highly-anticipated clinical outcomes from the Extreme Risk Study of the CoreValve U.S. Pivotal Trial.

The CoreValve Pivotal Trial presentation will kick-off the annual medical meeting's late-breaking clinical trials sessions this year, on the morning of Tuesday, Oct. 29.

"Unveiling the CoreValve U.S. Pivotal Trial data for the first time is a significant milestone as we work toward bringing more therapy options to patients in the U.S.," said John Liddicoat, M.D., senior vice president, Medtronic, and president of the Medtronic Structural Heart Business at Medtronic. "This study will provide vital information for physicians and their U.S. patients, many of whom have had no good option for treating their aortic stenosis."

Thursday's late-breaking clinical trials session includes two presentations involving Medtronic drug-eluting stents:

  • Conducted in Brazil, the OPTIMIZE study compared one-year outcomes in patients who received the Endeavor drug-eluting stent (DES) and stayed on dual antiplatelet therapy (DAPT) for either three or 12 months. It is the largest prospective randomized controlled trial (RCT) to examine DAPT discontinuation at three months after implantation of any DES.
  • Conducted in the Netherlands, the DUTCH PEERS study compared one-year outcomes in patients who received either the Resolute Integrity DES or the Promus Element DES from Boston Scientific. It is the first prospective RCT of "third-generation" drug-eluting stents.

At an oral presentation at TCT, the three-year follow-up results from Symplicity HTN-2, the first randomized clinical trial investigating renal denervation, will be presented.

The following presentations related to Medtronic therapies appear in chronological order in U.S. Pacific Daylight Time:
