1 year results of the TOTAL trial: Randomized trial of manual Thrombectomy in STEMI

SS Jolly, JA Cairns, S Yusuf, MJ Rokoss, P Gao, B Meeks, S Kedev, G Stankovic, R Moreno, A Gershlick, S Chowdhary, S Lavi, K Niemelä, I Bernat, WJ Cantor, AN Cheema, PG Steg, RC Welsh, T Sheth, OF Bertrand, A Avezum, R Bhindi, MK Natarajan, D Horak, RCM Leung, S Kassam, SV Rao, M El-Omar, SR Mehta, JL Velianou, S Pancholy, V Džavíkon behalf of the TOTAL Investigators

Canadian Institutes of Health ResearchCanadian Network and Centre for Trials Internationally (CANNeCTIN)Medtronic Inc.

Slide3

Background: Effect of Thrombectomy at 1 year

Large effect size in TAPAS (2008)No difference in TASTE (2013)Vlaar PJ, et al. Lancet 2008;371:1915-20.Frobert O, et al. N Engl J Med 2013.Lagerqvist B, et al. N Engl J Med. 2014.TAPAS trial (N=1071) showed a large benefit

vs

. TASTE (

N=7244) showed

no benefit of thrombus aspiration

Slide4

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:

P

ersistent 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 onsetSample size of 10,700 for 80% power to detect a 20% Relative Risk Reduction

Slide5

Summary of Primary Results of TOTAL trialImprovement in Surrogate Outcomes (ST resolution, Distal embolization)Thrombectomy did not reduce primary outcome at 180 days

Increase in stroke at 30 daysQuestion:Would the benefit for surrogate outcomes translate into a long term benefit at 1 year?Jolly SS, et al. N Engl J Med. 2015;372:1389-1398.

ConclusionsRoutine thrombectomy compared to PCI alone did not reduce CV death, MI, shock or heart failure at 1 year

Routine thrombectomy was associated with increased rate of strokeManual Thrombectomy can no longer be recommended as a routine strategy
