Core Tip

Core tip: Distal coronary embolization occurs predominantly at the time of the initial balloon or stent inflation, so thrombus burden reduction by thrombectomy devices before percutaneous coronary intervention may decrease the dangerous phenomenon of no-reflow. Manual aspiration catheters are the most commonly used devices. Several randomized trials have demonstrated the efficacy and safety of pretreatment with manual thrombectomy during primary percutaneous coronary intervention. There are some unanswered questions about thrombus aspiration, including whether there is truly a mortality benefit, which subgroups may or may not benefit from aspiration, and whether patients with a large thrombus burden are better treated with mechanical thrombectomy.
