Rotational coronary atherectomy in acute ST-segment elevation myocardial infarction

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Medicine

Background:

• Large thrombus burden in acute ST-elevation myocardial infarction (STEMI) often leads to slow-flow or no-reflow phenomena during percutaneous coronary intervention (PCI).
• Rotational atherectomy is generally contraindicated in STEMI due to concerns about increased platelet activation and aggregation.
• Complex coronary anatomy can pose significant challenges during primary PCI for STEMI.

Observation:

• A case of STEMI with a large thrombus load and complex vessel geometry required intervention.
• The Rotablator, a rotational atherectomy device, was the only available option for pretreatment.
• The procedure involved primary PCI with mandatory atherectomy due to vessel complexity.

Findings:

• Successful use of rotational coronary atherectomy in the setting of acute STEMI.
• The Rotablator facilitated the PCI procedure despite initial contraindications.
• Achieved successful reperfusion in a challenging STEMI case.

Implications:

• This case suggests that rotational atherectomy may be a viable option in select STEMI cases with complex anatomy.
• Challenges traditional contraindications for atherectomy in acute myocardial infarction.
• Opens potential avenues for managing complex STEMI interventions where conventional methods are insufficient.
