Comparison of AngioJET Rheolytic Thrombectomy Before Direct Infarct Artery STENTing with Direct Stenting Alone in Patients with Acute Myocardial Infarction: the JETSTENT trial David Antoniucci on behalf of the JETSTENT Investigators

After angiography and IRA wiring: thrombus grade 3 to 5 Pts with STEMI admitted within 12 hours from symptom onset Lysis Stroke < 30 days Surgery < 6 weeks Pre-stented IRA Rheolytic Thrombectomy +DSDirect Stenting (DS) Study Design Randomization 1:1 N = 500
Technique for AngioJet Use and DS Single pass anterograde technique (activate AngioJet proximal to thrombus) Angiographic check after first AngioJet pass. Temporary pacemaker strongly discouraged. Balloon pre-dilation strongly discouraged. DS had to be attempted in all cases in both arms. Routine Abciximab in both arms.
JETSTENT TRIAL Primary surrogate end points: Early ST-segment resolution ( 50% ST segment elevation reduction at 30 minutes) Infarct size (1-month 99m Tc sestamibi scintigraphy) Clinical end points: MACE at 1, 6, and 12 months Death and Readmission for CHF at 12 months Secondary surrogate end points: TIMI flow, cTFC, and TIMI blush
Predictors of ST-Segment Resolution and 6-Month MACE 6-month MACEHR95%CIp value Randomization to RT0.500.31 – 0.82.006 Age (yrs)1.021.01 – 1.04.023 Bleeding4.331.80 – 10.42.001 30 min.

Conclusions AngioJet rheolytic thrombectomy before direct IRA stenting as compared to direct stenting alone is associated with: o Better myocardial reperfusion (higher rate of early STR) o Improved 6-month clinical outcome (lower MACE rate) The results of the JETSTENT trial support the routine use of AngioJet rheolytic thrombectomy in AMI patients with evidence of thrombus.
