Abstract

Background: Intravascular ultrasound (IVUS)is a new imaging technique that facilitate the process of coronary intervention. The angiographic evaluation of left main lesions significance is always questionable, IVUS detect the significance, guide the procedure and some studies proves a benefit in mortality.

Aim of the Work: We aimed to determine if intravascular ultrasonography (IVUS) guided Left Main coronary intervention may enhance clinical results compared with angiographic-guided Left main coronary PCI.

Patients and Methods: 60 patients who were eligible for Left Main Coronary Intervention were split into two groups for this controlled trial between 2021 and 2022 at the Maadi Military Hospital and the Cardiology Department of the Faculty of Medicine at Al-Azhar University: the IVUS-guided group (n-30) and the angiographic-guided group (n-30), The key composite end goal was the frequency of major adverse cardiac events (MACE):  As the main composite end goal, records of 6 Months of follow-up of (stent thrombosis, target lesion revascularizations, myocardial infarction, or death) were made.

Results: We found that the rate of MACE at 6 months was less in the IVUS-guided group than in the control group. Compared to the control group, the IVUS-guided group had a decreased frequency of the main composite end outcome (death, reMI, TLR and stent thrombosis). (1 cases in IVUS group (3.3%), 10 cases in angiography group (33.3%) (P value 0.003).

Conclusion: The present study concluded that IVUS-guided LM intervention can improve MACE events as aprimary composit end point (death, reMI, TLR and stent thrombosis) at 6 months follow up.
