Định nghĩa
15th EBC consensus on bifurcation. 2021
Định nghĩa “Bifurcation lesion”
• A bifurcation lesion is “a coronary
artery narrowing occurring
adjacent to, and/or involving, the
origin of a significant SB”.
• A significant SB is a SB that the
operator does not want to lost in
the global context of a particular
patient.
(adjacent to = 3– 5 mm)
Bifurcation anatomy description
• Prox. MV, DistalMV, SB
• Carina
• Angulation of distal MV and SB

Main determinants of bifurcation PCI complexity
15th EBC consensus on bifurcation. 2021
General approach to bifurcation stenting
• PCI on bifurcation stenting should adhere to a KISS (keep it simple
and safe) principle.
• Systematically wire both branches.
• Try to limit the number of stents.
• Aim for well apposed and well expanded stents with limited
overlaps

• Sang thương phân nhánh là sang thương phức tạp
• Chiến lược 1 stent chờ (Provisional) nên được lựa chọn đầu

• Hiệu quả của can thiệp sang thương phân nhánh ngày càng
được cải thiện tốt hơn do kỹ thuật, dụng cụ ngày càng tối ưu
• IVUS giúp tránh những lỗi có thể gặp trong từng bước và giúp
tối ưu từng bước trong can thiệp sang thương phân nhánh
