What is a bifurcation stent?
Table of Contents
Bifurcated stent system is a novel platform designed reproducibly to permit stenting in bifurcation lesions regardless of branch angulation or plaque location, in a short simple procedure.
What is coronary bifurcation?
A bifurcation is defined as a division of a main, parent branch into two daughter branches of at least 2.0 mm. Bifurcation lesions in coronary artery disease (CAD) are common, encompassing 15-18% of lesions treated with percutaneous coronary intervention (PCI).
Why do Atheromas tend to form at points of bifurcation in an artery?
Atherosclerotic lesions develop predominantly at branches, bends, and bifurcations in the arterial tree because these sites are exposed to low or disturbed blood flow, which exerts low/oscillatory shear stress on the vessel wall.
What is bifurcation in nursing?
a division into two branches, such as a blood vessel, or a tooth that has two roots.
Do you need two stents for a bifurcation lesion?
Bifurcation lesions: no need to implant two stents when one is sufficient! Eur Heart J. 2016;37:1929–1931. [PubMed] [Google Scholar] 7. Serruys PW. The treatment of coronary bifurcations: a true art form. EuroIntervention. 2015;11(Suppl V):V7. [PubMed] [Google Scholar] 8.
What is the approach to bifurcation lesions in PCI?
3. BASIS The approach to bifurcation lesions is based on the angiographic configuration of the lesion (s) in the main branch and the side branch Significant disease (>50% stenosis) in the ostium of the side branch increases the likelihood of side-branch closure as well as the restenosis rate after PCI 4.
What is the best 2-stent technique for stent expansion?
Maybe the optimal result especially in term of stent expansion is much more important than the selection of a specific 2-stent technique. Currently most popular techniques are T-stent and small protrusion, mini-crush technique, mini-culotte technique, and DK-crush technique.
How do you crush a stent in a heart?
Following the placement of a stent in the SB, an appropriately sized balloon is positioned in the MB at the level of the bifurcation, before retracting the SB stent 2–3 mm into the MB and deploying it. If the result in the SB is satisfactory, the deploying balloon and SB wire are removed and the MB balloon is inflated, thus crushing the SB stent.
