  1. TITAN STENTtitanium nitride oxide coated stent • F.FUNCK .M.D. • PONTOISE HOSPITAL /PARIS UNIVERSITY • FRANCE

  2. WHICH STENT FOR WHICH PATIENT ? • REGARDING THE RATE OF RESTENOSIS WITH BMS, SOME CARDIOLOGISTS WERE LOOKING FORWARD TO USE DRUG ELUTING STENT (DES ) • IN EUROPE ,THE RATE OF USE OF DES IS DEPENDING ON THE COUNTRY (BETWEEN 40 AND 70 % ) • INTERNATIONAL DEBATE (ESC 2006 ) AROUND THE RISK OF DES ( ACUTE THROMBOSIS, LATE THROMBOSIS ,..) • EUROPEAN GUIDELINES TO CONTINUE ANTIPLATELET TREATMENT 1 YEAR; • BLEEDING RISK OF THIS KIND OF TREATMENT (ESP. IF GENERAL SURGERY IS SCHEDULED OR HIGH RIK PATIENT )

  3. WHICH STENT FOR WHICH PATIENT ? • MORE THROMBOSIS WITH DES ? • META ANALYSIS OF INTERNATIONAL STUDIES GIVE DIFFERENT RESULTS BUT • MORE COMPLICATIONS IF DES ARE USED FOR « OFF LABEL » INDICATIONS • ON LABEL INDICATIONS ARE IN EUROPE ( PROXIMAL LAD, DIABETIS PATIENT ,SMALL VESSELS , RESTENOSIS INTRASTENT ,.. )

  4. IS THERE AN ALTERNATIVE SOLUTION OF USE OF DRUG ELUTING STENT ? …….

  20. One Year Clinical Outcome %

  21. Titan Registry - Conclusions • Titanium-Nitride-Oxide coated stents are safe and effective in complex patients enrolled in routine clinical practice • As opposed to drug-eluting stents, Titanium-Nitride-Oxide coated stents require only short-term dual antiplatelet therapy • Rates of TLR and MACE of Titanium-Nitride-Oxide coated stents are low and deserve further evaluation in direct head-to-head comparison with drug-eluting stents

  22. Inclusion Criteria: • Written informed consent • Age > 18 years • Patient with symptoms and signs of myocardial infarction requiring PCI Exclusion Criteria: •Prior PCI on target vessel (restenosis) • Unprotected LM disease • Ostial lesion • Contraindication to aspirin, heparins, clopidogrel, (allergy / risk for bleeding) • Life expectancy < 12 months • Stent length needed > 28 mm Purpose of the TITAX AMI trial Initiated by the investigators A Prospective, Multi-center, Randomized Trial that Compares the Implantation of Titanium-Nitride-Oxide Coated Stents to Paclitaxel-Eluting Stents for Acute Myocardial Infarction

  28. TITAX AMI trial: Conclusions •Both TITANOX coated stent and PES resulted in comparable clinical outcome. • Secondly, although the overall risk of stent thrombosis was low, it concentrated on the use of PES. • Stent thrombosis occurred in 3 patients after premature discontinuation of clopidogrel.

  37. • The 519 patients (TITANOX 184, PES 183, BMS 152) who were MACE free at the time of the discontinuation of clopidogrel treatment were followed for an additional 12 months after discontinuation. • The goal was to evaluate late thrombotic events related to clopidogrel discontinuation. Late Follow up in the Year Following Clopidogrel Discontinuation

  38. Late Follow up in the Year Following Clopidogrel Discontinuation % All Death / Cardiac death p = 0.007 Stent Thrombosis, p = 0.007 MACE, p = 0.10

  39. PORI Stent RegistriesConclusions • Lower rates of recurrent MI and MACE with the use of TITANOX coated stent compared with PES or BMS • Secondly, very low TLR rate with the use of TITANOX coated stent (5.5 %) • PES higher rates of MI and Stent Thrombosis after the discontinuation of clopidogrel compared with TITANOX coated stent or BMS
