What is Medina classification?
The simplest and most widely used is the Medina classification. The Medina classification assesses plaque burden based on the presence (“1”) or absence (“0”) of stenosis in the proximal MB, distal MB, and SB (Figure 1).
What are bifurcation 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 bifurcation stenting?
A technique commonly used for bifurcations is kissing balloon angioplasty, in which two balloons are inflated simultaneously to prevent the shifting of plaque into the side branch. Provisional side branch stenting is the technique of using a stent for the main branch, and stenting the side branch only if necessary.
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).
What is LAD medical term?
The left anterior descending artery (LAD) is the largest coronary artery runs anterior to the interventricular septum in the anterior interventricular groove, extending from the base of the heart to the apex.
What is bifurcation stenosis?
Stenoses, or narrowing, located in a main coronary artery and an adjoining side-branch vessel is called a bifurcation blockage or bifurcation lesion.
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 a normal LAD score?
Obviously, a score of “zero” is optimal, and a score of >300 (or >400, depending upon who you listen to) warrants further work-up, like a treadmill test or nuclear study. A higher score does NOT correlate with the SEVERITY of any particular stenosis.
What is LAD in heart scan?
What is the Medina classification of lesions?
Interestingly, this often well quoted classification in interventional cardiology was initially published as a ‘Letter to the Editor’ by Medina A and colleagues. The true bifurcation lesions are those belonging to the Medina classes 1.1.1, 1.0.1, and 0.1.1 where both the main branch and side branch are significantly narrowed.
What is Medina 1 0 0 0?
If only proximal segment of the main branch has a significant lesion, it becomes Medina 1,0,0. If distal segment of main branch alone is involved, it becomes 0,1,0. Sole involvement of side branch is designated 0,0,1 and involvement of all the three is designated 1,1,1 and so on.
What is the Medina value for a lesion on a branch?
If only proximal segment of the main branch has a significant lesion, it becomes Medina 1,0,0. If distal segment of main branch alone is involved, it becomes 0,1,0.
