Thrombus-Demarcated Stenting with Dual-Contrast Imaging: A Novel Approach for Late-ST-Segment Elevation Myocardial...

Area of Science:

• Interventional Cardiology
• Cardiovascular Imaging
• Acute Myocardial Infarction Management

Background:

• Revascularization success in acute ST-segment elevation myocardial infarction (STEMI) with dense thrombus is vital for patient prognosis.
• Stenting without thrombus dispersion can improve outcomes in these challenging lesions.
• Unsuccessful predilatation poses a significant hurdle in achieving successful revascularization.

Observation:

• A novel "thrombus-demarcated stenting" technique utilizing a dual-contrast imaging approach was employed.
• This technique was applied in a case of late-inferior STEMI with a total occluded coronary lesion.
• Predilatation attempts were unsuccessful prior to the implementation of this novel stenting method.

Findings:

• The thrombus-demarcated stenting with dual-contrast imaging successfully navigated the occluded lesion.
• This approach allowed for effective stent placement despite prior difficulties with predilatation.
• The technique provided clear visualization of the thrombus, guiding precise stent deployment.

Implications:

• This case demonstrates a viable alternative strategy for complex STEMI interventions.
• The dual-contrast imaging approach can enhance procedural safety and efficacy in thrombus-rich lesions.
• This technique is particularly valuable in centers lacking advanced imaging modalities like optical coherence tomography.
