What is bifurcation coronary lesions?

What is bifurcation coronary lesions?

A bifurcation lesion is a coronary artery narrowing occurring adjacent to, and/or involving, the origin of a significant side branch that you do not want to lose. The very simple Medina classification is intended for exchange and clinical research purposes.

What is a bifurcated stent?

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 a bifurcation procedure?

Bifurcation is the splitting of a case into two separate trials. Generally, a civil lawsuit can be naturally divided into two major issues for a trier of fact, such as a judge or a jury, to decide: liability and damages. In a bifurcated case, the issues of liability and damages are decided separately.

What is bifurcation disease?

Bifurcation lesions are often defined as involving a branch vessel ≥2.25 mm arising from a main vessel. Patterns of bifurcation disease are also defined and classified according to the location (main branch only, side branch only, or both main vessel and side branch). CURRENT TECHNOLOGY.

What does bifurcation mean in medical terms?

[bi-fur-ka´shun] 1. a division into two branches, such as a blood vessel, or a tooth that has two roots. Bifurcatio aortae (aortic bifurcation), showing the branching of the abdominal aorta into the common iliac arteries, and from there to the internal and external iliac arteries.

What is bifurcation of the heart?

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).

Where does the bifurcation occur in relation to the heart?

A coronary bifurcation lesion occurs at or near a division of a major coronary artery. Characterizing bifurcation lesions involves assessing the lesion morphology in three important anatomic segments: (1) proximal main branch (MB); (2) distal MB; and (3) side branch (SB).

Why does bifurcate mean?

: to divide into two branches or parts The stream bifurcates into two narrow channels.

What causes bifurcation?

Global bifurcations occur when 'larger' invariant sets, such as periodic orbits, collide with equilibria. This causes changes in the topology of the trajectories in the phase space which cannot be confined to a small neighbourhood, as is the case with local bifurcations.

What is bifurcation PCIe?

What is PCIe bifurcation? PCI Express bifurcation means splitting the PCI Express bus into smaller buses, and in this case splitting a 16-lane PCIe Gen 3 into a 2 x 8-lane PCIe Gen3 interface. Servers supporting PCIe bifurcation have a BIOS setting for enabling the feature.

What is the meaning of bifurcation in anatomy?

• 2. the point at which division into two branches occurs. Carotid bifurcation: the site of division of the common carotid artery into the external and internal carotid arteries. bifurcation. a splitting into two branches, such as the trachea, which branches into the two bronchi.

What is the carotid bifurcation?

• The carotid bifurcation is the point at which the common carotid artery terminates. As it does so, it forms the internal and external carotid arteries which go on to supply the head and neck.

What is Carina bifurcation?

• The carina is the inflection point at which the proximal MB bifurcates into the distal MB and SB. The European Bifurcation Club defines a bifurcation lesion as a significant stenosis (i.e., >50%) in a coronary artery adjacent to and/or involving the origin of an SB that is clinically significant.

What is a bifurcatio aorta?

• Bifurcatio aortae (aortic bifurcation), showing the branching of the abdominal aorta into the common iliac arteries, and from there to the internal and external iliac arteries.
