A typical example of thrombus-containing lesion in ST-segment elevation acute myocardial infarction (STEMI). Culprit lesion thrombus extraction using CAT RX contact aspiration system with sustained vacuum assistance. A – 12-lead electrocardiogram (ECG) in a 52-year-old patient, smoker, admitted after resuscitated cardiac arrest; note ST-segment elevations in antero-lateral leads (arrows). B – Emergency coronary angiography revealed a thrombotic lesion (arrows) in the intermediate branch (IM) of the left coronary artery; the flow was impaired (thrombolysis in myocardial infarction – TIMI grade 2). C – Consistent with totality of evidence [11], primary aspiration thrombectomy with stent placement intention was applied to minimise myocardial tissue loss. A single passage of the CAT RX (Penumbra) 6F mechanical vacuum-assisted coronary aspiration catheter system (tip marked with arrows, see also the photograph in D) resulted in evacuation of the thromboembolic lesion material (cf., E). D – Indigo CAT RX Neuro-Tracking Technology catheter for coronary thrombus aspiration (Thr – thrombus contact extraction lumen, GW – guidewire lumen); Penumbra Controlled Vacuum Engine filter is shown in E. E – Thrombus evacuated in this procedure (Penumbra Controlled Vacuum Engine filter in the background). F – Direct implantation (top) of a drug-eluting stent (Cruz 3.0 × 16 mm), note proximal stent edge in the ostial position; followed by non-compliant balloon (3.5 × 6 mm) sequential stent optimization (bottom, inflations up to 20 atm), ClearStent image in the inset. G – Final angiogram depicting an optimal angiographic result with TIMI 3 flow. H – Intravascular ultrasound run, showing optimal stent expansion and apposition in absence of any thrombotic material in the lumen – consistent with a safe and effective, complete thrombus extraction. I – 12-lead ECG performed immediately after procedure; note ST-segment regression by over 70% (consistent with effective myocardial tissue reperfusion). This was associated with a complete relief of chest pain and haemodynamic improvement
