A novel application of GuideLiner catheter for thrombectomy in acute myocardial infarction: a case series.

Angiographically visible thrombus and distal embolization are relatively common during percutaneous coronary intervention (PCI) in myocardial infarction (MI) and correspond to worse outcomes. Several aspiration and thrombectomy devices have been shown to be effective for prevention of distal embolization. We present a technique with successful use of the GuideLiner catheter (Vascular Solutions) for thrombus aspiration after dedicated manual aspiration thrombectomy devices have failed. Our case series includes large thrombus burden in clinical scenarios of ST-elevation MI in a native vessel, non-ST elevation MI in a vein graft, and ST-elevation MI due to native vessel in stent thrombosis.
