1 TOTAL Randomized trial of manual aspiration Thrombectomy + PCI vs. PCI Alone in STEMI (TOTAL) SS Jolly, JA Cairns, S Yusuf, B Meeks, J Pogue, MJ Rokoss, S Kedev, L Thabane, G Stankovic, R Moreno, A Gershlick, S Chowdhary, S Lavi, K Niemelä, PG Steg, I Bernat, Y Xu, WJ Cantor, C Overgaard, C Naber, AN Cheema, RC Welsh, OF Bertrand, A Avezum, R Bhindi, S Pancholy, SV Rao, MK Natarajan, JM ten Berg, O Shestakovska, P Gao, P Widimsky, V Džavík on behalf of the TOTAL Investigators

2 TOTAL Disclosures TOTAL trial was funded by: Canadian Institutes of Health Research Canadian Network and Centre for Trials Internationally (CANNeCTIN) Medtronic Inc.

3 TOTAL Rationale for Thrombectomy Major Limitation of Primary PCI: Distal Embolization and Reduced Flow Hypothesis: Aspiration thrombectomy may reduce embolization and improve clinical outcomes

4 TOTAL Background Large effect size in TAPAS (2008)No difference in TASTE (2013) Vlaar PJ, et al. Lancet 2008;371: Frobert O, et al. N Engl J Med Lagerqvist B, et al. N Engl J Med TAPAS trial (N=1071) showed a large benefit vs. TASTE (N=7244) showed no benefit of thrombus aspiration

5 TOTAL The TOTAL Trial Study Design PCI Alone (only bailout thrombectomy) Routine Upfront Manual Thrombectomy followed by PCI Primary Outcome: CV death, MI, cardiogenic shock and class IV heart failure ≤180 days Safety Outcome: Stroke ≤30 days 1:1 Randomization between strategies Bailout Thrombectomy allowed if PCI alone strategy fails: Persistent TIMI 0 or 1 flow with large thrombus after balloon pre-dilatation Persistent large thrombus after stent deployment at target lesion STEMI* with Primary PCI ≤12 hours of symptom onset Sample size of 10,700 for 80% power to detect a 20% Relative Risk Reduction

15 TOTAL Subgroup Analysis Primary Outcome

16 TOTAL 16 Limitations Operators not blinded Slightly lower use of GP IIb/IIIa inhibitors in Thrombectomy group Strategy trial of routine thrombectomy Cannot rule out a benefit of selective thrombectomy Control Arm had Bailout thrombectomy (7%) when PCI alone strategy failed Not designed to test effectiveness of bailout. Clinical judgement still needed. Stroke findings are unexpected Requires confirmation in other studies Analyses are ongoing to understand etiology

17 TOTAL Conclusions Routine thrombectomy compared to PCI alone with only bailout thrombectomy did not reduce CV death, MI, shock or heart failure within 180 days Routine thrombectomy was associated with increased risk of stroke within 30 days TOTAL and TASTE emphasize the need to conduct large randomized trials of common interventions even when small trials appear positive
