Insights
Excimer laser coronary angioplasty (ELCA) effectively treated residual distal thrombus in a ST-segment elevation acute myocardial infarction (STEMI) patient. This intervention improved distal coronary artery flow after primary percutaneous coronary intervention.
Area of Science:
- Cardiology
- Interventional Cardiology
- Vascular Medicine
Background:
- Residual thrombus is a significant prognostic factor in ST-segment elevation acute myocardial infarction (STEMI).
- Excimer laser coronary angioplasty (ELCA) is a potential treatment modality for residual thrombus.
- Persistent distal coronary thrombus after primary percutaneous coronary intervention (PCI) can adversely impact patient outcomes.
Background:
Residual thrombus, a prognostic factor in ST-segment elevation acute myocardial infarction (STEMI), can be treated with excimer laser coronary angioplasty (ELCA).
Case Summary:
A 59-year-old man admitted with chest pain was diagnosed with STEMI. Emergency coronary angiography confirmed complete occlusion of the proximal right coronary artery. A stent was placed at the lesion site; angiography revealed a translucent thrombus in the distal right coronary artery. ELCA with a 0.9-mm probe, followed by 1.4-mm probe, was performed at maximum output with a backward pull. Subsequent angiography revealed improvements in the translucent image.
Discussion:
In patients with STEMI, persistent residual distal coronary thrombus after primary percutaneous coronary intervention may negatively affect prognosis. Here, ELCA successfully resolved residual thrombus in the distal coronary artery.
Take-Home Message:
ELCA may be considered in select cases with residual distal thrombus after primary percutaneous coronary intervention, particularly when the distal coronary artery is not tortuous.
