What is bifurcation lesion?
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 bifurcation angle?
The angle between centerlines of the proximal main vessel and the side branch (angle A) was defined as take-off angle; the angle between centerlines of the distal main vessel and the side branch (angle B) was the most commonly used angle and was usually called “bifurcation angle,” which was considered as the critical …
What does unprotected left main mean?
unprotected left main disease (also called ULMD) refers to patients without bypass to the left coronary circulation 2. distal bifurcation disease refers to lesions involving the origins of the left anterior descending and left circumflex arteries (also called left main equivalent disease) 1.
What is bifurcation disease?
Coronary artery bifurcation disease (CABD) occurs in 15–20% of coronary artery disease (CAD) patients undergoing percutaneous coronary intervention (PCI) [1, 2] and remains a challenge in interventional cardiology even though coming modern interventional stent and technique in the last decades.
What is Medina classification?
The Medina classification describes a bifurcation lesion with three numbers that aim to define the pattern of the atherosclerotic disease based on angiographic appearance. 8 Each number is designated either 1 or 0 to indicate the presence or absence of a significant (>50%) stenosis.
What is kissing balloon technique?
Kissing balloon angioplasty reduces the rate of transient side-branch occlusion compared to sequential PTCA but does not improve immediate or long-term outcome compared to sequential PTCA for stenting of bifurcation lesions.
What is DK crush technique?
Clinical data have supported the advantages of the double kissing (DK) crush technique, which consists of stenting the side branch (SB), balloon crush, first kissing, stenting the main vessel (MV) and final kissing balloon inflation, for complex coronary bifurcation lesions compared to other stenting techniques.
What is a kissing stent?
Kissing stent reconstruction is a widely used technique for the management of aortoiliac occlusive disease involving the aortic bifurcation or proximal common iliac arteries.
What is proximal optimization technique?
The proximal optimisation technique (POT) has been proposed as a strategy to improve the results of stent scaffolding of bifurcation lesions. It is a straightforward technique whereby a short, appropriately-sized balloon is inflated in the main vessel just proximal to the carina.
What does a low syntax score mean?
Low SYNTAX scores are 27. High scores are associated with increasing cardiac mortality, major adverse cardiac events, and a specific, predefined combination of end points. The SYNTAX angiographic grading system was used alone to identify potential risk for revascularization.
Which artery is referred to as the Widowmaker?
A widowmaker is an informal term for a heart attack that involves 100 percent blockage in the left anterior descending (LAD) artery, says Stanley Chetcuti, M.D., an interventional cardiologist at the University of Michigan Frankel Cardiovascular Center.
How long do kissing stents last?
Technical and short term clinical success for kissing stents in the treatment of aortoiliac occlusive disease is acceptable. Patency beyond 18 months is inferior to that associated with bypass surgery. Kissing stents should be reserved for patients at high risk, with limited life expectancy.
What’s the difference between OM2 and OM3?
Both OM1 and Om2 utilizes an LED light source for transmission, however OM1 is commonly used for 100Mbps applications which OM2 is generally used for 1000Mbps applications. OM3 and OM3 share many features including an aqua colored jacket, a core size of 50um, and a data rate of 10GB at 850nm.
Why is the LAD called the Widowmaker?
The LAD artery carries fresh blood into the heart so that the heart gets the oxygen it needs to pump properly. If it’s blocked, the heart can stop very fast — which is why this type of heart attack is called a “widowmaker.” But the widowmaker isn’t always fatal.
