  3. Elderly PCI patients • CAD is highly prevalent: complex, severe, and diffuse • In US national registries in 2016 1 : 25% of PCI in patients ≥ 75y • Poorly represented in prior studies on DES and DAPT duration • No clear recommendation for PCI strategies Often treated with BMS and short DAPT (*), as a strategy to limit bleeding complications 2 (*) Short DAPT: 1mo in stable patients, ≥ 6mo in unstable patients (per ESC guidelines) 1.

  5. SENIOR Study Hypothesis To demonstrate that a thin struts DES & short BMS-like DAPT in elderly patients is associated with: - a lower rate of MACCE at 1 year vs. BMS (efficacy) - a similar risk of bleeding at 1 year vs. BMS (safety) - a similar risk of stent thrombosis at 1 year vs. BMS (safety ) www.ClinicalTrial.gov: NCT NCT02099617

  6. SENIOR Trial design Randomized (1:1), single blind trial 1,200 patients aged 75 years and above Tailored DAPT: 1 mo in stable and 6 mo in ACS pts Prespecified by the investigator prior to randomization DES BMS Vs.

  20. Summary The SENIOR trial evaluated a bioabsorbable polymer DES vs. BMS in elderly patients treated with short DAPT • MACCE was lower with DES (11.6% vs 16.4%, p=0.0172) • This was mainly driven by ID-TLR (1.7% vs 5.9%, p=0.0002) • DAPT duration and bleeding were similar in the two groups • ST was low and not different (0.5% vs 1.4%, p=0.12) All TVT 2016 faculty disclosures are listed online and on the app.

  21. Conclusion PCI with a contemporary thin struts DES is more effective , and as safe as BMS in elderly patients with CAD, on a short DAPT tailored to their clinical presentation BMS should no longer be used as a strategy to reduce DAPT duration in elderly patients All TVT 2016 faculty disclosures are listed online and on the app.
