Ultra-Deep Guide Catheter Intubation for Direct Thromboaspiration in Acute Myocardial Infarction

Area of Science:

• Cardiology
• Interventional Cardiology
• Vascular Medicine

Background:

• High thrombus burden is a significant mortality risk factor in primary percutaneous coronary interventions (PCI), particularly when distal embolization occurs.
• Routine thrombus aspiration is not recommended in acute coronary syndrome (ACS) primary PCI.
• Challenging cases may require advanced techniques when conventional devices fail to achieve adequate thrombus removal and vessel reperfusion.

Observation:

• A 60-year-old male presented with a late-comer infero-lateral ST-segment elevation myocardial infarction (STEMI).
• The patient underwent primary PCI of the right coronary artery.
• A high thrombotic burden was evident during the procedure.

Findings:

• Conventional devices were insufficient for thrombus removal and vessel reperfusion.
• An ultra-deep guide catheter intubation technique was employed.
• Successful thromboaspiration and stenting were achieved.

Implications:

• This case demonstrates the utility of ultra-deep guide catheter intubation for managing high thrombus burden in complex STEMI.
• Advanced techniques may be necessary when standard approaches are inadequate.
• Effective thrombus management is crucial for improving outcomes in primary PCI.
