Chinese Bifurcation Summit (CBS): Left Main Bifurcations-IVI-Guidance in Bifurcation Stenting

Video Transcription

Video Summary

In a webinar presented during a joint session between SKY and CBS, Dr. Junjie Zhang discussed the importance of using intracoronary imaging to guide bifurcation stenting. He highlighted how conventional angiography often underestimates lesion severity compared to IVI (intravascular imaging). The session covered the limitations of the Medina classification in bifurcation management and introduced the definition criteria for assessing bifurcation lesions' complexity. Studies presented showed the superiority of IVAS (intravascular ultrasound) over traditional angiography in reducing major adverse cardiac events and improving long-term outcomes in patients. The OCT (optical coherence tomography) trial demonstrated lower rates of MACE (major adverse cardiac events) with OCT guidance versus angiography. The Chinese Guidelines for PCI recommend using IVAS or OCT for complex bifurcation lesions. Dr. Zhang emphasized the importance of pre-procedural imaging to improve lesion preparation, highlighting techniques like DK-CRUSH for complex cases and discussing ongoing trials to refine stenting practices.
