Manual Thrombus Aspiration (MTA) reduces thrombus burden and improves myocardial reperfusion markers in patients with ST-segment elevation myocardial infarction (STEMI), however its clinical benefit is controversial due to conflicting results from randomized clinical trials, which is why the benefit of its application during primary angioplasty (PA) remains uncertain. Reports such as that of Doo Sun Sim, et al. suggest that the impact of MTA may become clinically relevant in patients with a longer total ischemia time.1 We present the case of an adult male, with multiple risk factors for coronary disease, with lower STEMI, due to occlusion of the right coronary artery with a heavy thrombus load and an ischemia time of 10 hours. It was successfully treated by MTA, removing abundant intracoronary thrombus and obtaining a TIMI III flow, without requiring stent implantation. The case, the evolution and the current knowledge regarding the use of AT are discussed. Our case report and review of five cases with similar characteristics in the literature illustrate the use of MTA in patients with STEMI, high thrombus burden, and prolonged ischemia time.
