Clinical Trial Summary

In high thrombus burden subgroup of Acute STEMI, manual aspiration thrombectomy was associated with reduced cardiovascular death but increased stroke or transient ischemic attack. The role of aspiration thrombectomy is still a matter of active debate. Manual aspiration suffers from decreasing aspiration force as the syringe fills with fluid and requires the operator to exchange syringes during the procedure to maintain suction.

Description:

Acute ST-segment elevation myocardial infarction (STEMI) poses a major hazard to human life and health due to its high morbidity and deaths. The frequency of STEMI is increasing. Although dual antiplatelet treatment (DAPT) and primary percutaneous coronary intervention (PPCI) have enhanced survival in STEMI suffers during the last 20 years. Complications after myocardial infarction continue to be a major contributor to high mortality and disability. Treatment focuses on minimizing infarct size by reopening the occluded artery and restoring myocardial perfusion While PPCI is an established treatment option and can reliably re-establish flow, it can also cause distal embolization, resulting in persistent microvascular obstruction and poor myocardial perfusion. Poor myocardial perfusion after PCI is associated with worse left ventricular functional recovery and increased long-term mortality. By removing thrombotic material, aspiration thrombectomy before PCI may reduce the risk of distal embolization and improve myocardial perfusion. A meta-analysis of large randomized trials comparing aspiration thrombectomy and PCI alone found that routine manual aspiration thrombectomy did not improve clinical outcomes. However, in the high thrombus burden subgroup, manual aspiration thrombectomy was associated with reduced cardiovascular death but increased stroke or transient ischemic attack. For select cardiac populations, particularly those with high thrombus burden, the role of aspiration thrombectomy is still a matter of active debate. Manual aspiration suffers from decreasing aspiration force as the syringe fills with fluid and requires the operator to exchange syringes during the procedure to maintain suction.
