Overview
Distal embolization during percutaneous coronary intervention is defined as occlusion of an instrumented vessel or branch due to downstream movement of either thrombus, atheroma, fracture of the distal tip of a coronary guidewire, an undeployed stent or air.[1] It is manifested clinically as either chest pain, ST segment elevation, no reflow during the procedure and / or a rise in biomarkers of myonecrosis (CK-MB or troponin) following the PCI.
Causes
- Thrombus
- Atheroma
- An undeployed stent
- Fracture of the distal tip of a coronary guidewire
- Air bubbles from manifold injections
Epidemiology and Demographics
Distal embolization occurs in approximately 10% of patients with an acute myocardial infarction undergoing PCI. Embolic complications occur more often in patients with acute MI and in patients undergoing balloon angioplasty of saphenous vein graft lesions, particularly those with recent total occlusion.
