ACI London 2010 Thrombectomy in STEMI … is the evidence clear? Brad Higginson International marketing manager
Options for Management of Thrombotic Lesions • Pharmacologic Therapies • Embolic Protection Devices • Filters • Balloon Occlusion • Mechanical Thrombectomy Devices • Rheolytic thrombectomy • Aspiration Thrombectomy Devices • Pharmacologic Therapies • Embolic Protection Devices • Filters • Balloon Occlusion • Mechanical Thrombectomy Devices • Rheolyticthrombectomy (AngioJet) • Aspiration Thrombectomy Devices Dr. Bruce Brodie LeBauer Heart , North Carolina
AngioJet history Over ½ million treated WW
Is a Class 1 , Level A guideline attainable? • Challenging the Class one distinction? • TAPAS • Bias between treatment arms • AiMI – AngioJet in Myocardial Infarction • Mortality endpoint • TIMI 3 flow baseline imbalance between treatment arms
TAPAS – NEJM Conclusion • Thrombus aspiration is applicable in a large majority of patients with myocardial infarction with ST-segment elevation, and it results in better reperfusion and clinical outcomes than conventional PCI, irrespective of clinical and angiographic characteristics at baseline.
TAPAS – NEJM , “respective” caveats Small thrombus burden 49% 44% 90% Thrombectomy was primary procedure 96% Predilation was primary procedure 00%
New England Journal of Medicine Dr. Vetrovec editorial
NEJM – technique editorial Dr. Vetrovec summarized Some operators believe that direct stenting without multiple balloon inflations reduces the risk of distal emboli. The majority of patients in the conventional-PCI group had balloon angioplasty followed by stenting, which might have increased the relative incidence of embolization in the conventional-PCI group.

AiMI Control Arm Mortality is Far Lower than in the Meta-Analysis PCI Arm There is extremely low, p=0.0007, chance that a new PCI trial would observe mortality of 0.8% or less AiMI PCI Arm is an outlier, extreme observation, or in the tail, as compared to the body of PCI evidence (N=124 Study Arms)
Is a Class 1, Level A guideline attainable? • Better science • TAPAS 2 • JETSTENT • Thrombus caveats • Large vs Small • Fresh vs Organized • Platelet rich versus Fibrin rich • Better science • TAPAS 2 • JETSTENT • Thrombus caveats • Large vs Small • Fresh vs Organized • Platelet rich versus Fibrin rich
