Area of Science:

• Cardiology
• Interventional Cardiology
• Medical Devices

Background:

• ST segment elevation myocardial infarction (STEMI) requires rapid reperfusion.
• Occluded coronary arteries (TIMI 0) present a challenge for timely restoration of blood flow.
• Mechanical thrombectomy offers a potential alternative to traditional angioplasty.

Purpose of the Study:

• To evaluate the efficacy and safety of Endicor X-Sizer thrombectomy followed by stenting in STEMI patients with occluded coronary arteries.
• To assess the impact of this strategy on ST-segment elevation reduction and clinical outcomes.

Main Methods:

• 16 STEMI patients with occluded coronary arteries underwent thrombectomy with the Endicor X-Sizer device and subsequent stenting.
• Coronary blood flow was assessed using TIMI (Thrombolysis In Myocardial Infarction) grading.
• Electrocardiograms (ECG) were analyzed pre- and post-intervention to measure ST-segment elevation changes.

Main Results:

• The thrombectomy device successfully crossed the occlusion in 15 of 16 patients, achieving TIMI 3 flow.
• All 15 patients maintained TIMI 3 flow after stenting.
• A significant reduction in ST-segment elevation (>50%) was observed in 13 patients, with >70% reduction in 11 patients.
• Low procedural complications and uneventful 30-day follow-up were reported.

Conclusions:

• Endicor X-Sizer thrombectomy is a feasible and effective mechanical reperfusion strategy for STEMI.
• This approach leads to rapid restoration of coronary blood flow and significant ST-segment resolution.
• Thrombectomy followed by stenting presents an attractive option for acute myocardial infarction management.
