Abstract
BackgroundLarge thrombus burdens in ectatic coronary arteries that remain after aspiration thrombectomy can negatively impact outcomes following percutaneous coronary interventions in patients with acute myocardial infarction.Case presentationA 53-year-old man presented with ST-segment elevation myocardial infarction (STEMI). Coronary angiography revealed an ectatic right coronary artery (RCA) that was completely occluded in the mid portion by a large amount of thrombus. Catheter-directed intracoronary thrombolysis with alteplase led to recovery of coronary blood flow, which multiple attempts of aspiration thrombectomy had failed to achieve. Coronary angiography 9 days later showed good blood flow and insignificant stenosis remaining in the RCA; this had completely resolved in 6 months’ follow-up coronary angiography.ConclusionCatheter-directed intracoronary thrombolysis can be performed effectively and safely when repeat aspiration thrombectomy fails to produce satisfactory coronary reperfusion in STEMI patients with large thrombus burdens in ectatic coronary arteries.
Highlights
Large thrombus burdens in ectatic coronary arteries that remain after aspiration thrombectomy can negatively impact outcomes following percutaneous coronary interventions in patients with acute myocardial infarction.Case presentation: A 53-year-old man presented with ST-segment elevation myocardial infarction (STEMI)
The beneficial effect of manual aspiration thrombectomy (MAT) during primary Primary percutaneous coronary intervention (PCI) is still open to debate, it is frequently employed as a first-line therapy to reduce these adverse events [3]
We report a case of successful coronary reperfusion through a combination of catheter-directed intracoronary thrombolysis and MAT in STEMI caused by thrombotic occlusion of an ectatic coronary artery
Summary
Catheter-directed intracoronary thrombolysis can be performed effectively and safely when repeat aspiration thrombectomy fails to produce satisfactory coronary reperfusion in STEMI patients with large thrombus burdens in ectatic coronary arteries.
