Abstract

This randomized trial compared rheolytic thrombectomy before direct infarct artery stenting with direct infarct artery stenting alone in 100 patients with a first acute myocardial infarction (AMI). The primary end point of the study was early ST-segment elevation resolution, and the secondary end points were corrected Thrombolysis In Myocardial Infarction (TIMI) frame count, infarct size, and 1-month clinical outcome. The primary end point rates were 90% in the thrombectomy group and 72% in the placebo group (p = 0.022). Randomization to thrombectomy was independently related to the primary end point (odds ratio 3.56, p = 0.032). The corrected Thrombolysis In Myocaridal Infarctions (TIMI) frame count was lower in the thrombectomy group (18.2 ± 7.7 vs 22.5 ± 11.0, p = 0.032), and infarct size was smaller in the thrombectomy group (13.0 ± 11.6% vs 21.2 ± 18.0%, p = 0.010). At 1 month, there were no major adverse cardiac events. Rheolytic thrombectomy before routine direct infarct-related artery (IRA) stenting is highly feasible and provides more effective myocardial reperfusion in patients undergoing percutaneous coronary intervention for AMI.

    Mechanical aspiration with a continuous vacuum pump appears as a very promising strategy in this scenario, although only a single arm large prospective registry has been performed to date [13]. Rheolytic thrombectomy can break and aspirate thrombus, and has been extensively studied in STEMI with conflicting results [14]. A first ‘all comers’ trial in STEMI showed no benefit and actual harm with the device [15], whereas a second trial limited to large thrombus burden showed better ST segment resolution and improved clinical end-points [16].

    Thrombus aspiration devices can be classified as “manual” or “mechanical” depending on the presence or absence of a motorized system [8]. Several studies have been conducted on the efficacy of manual thrombus aspiration systems compared with standard PCI [9–16], and a lower number of studies and also some meta-analyses have examined the effects of mechanical devices versus standard PCI [17–20] or manual devices [21,22]. Angiojet is usually considered as more expensive and complex but it is also more powerful in thrombus removal as compared with manual systems [21].
