What is ramus disease?

The ramus intermedius (RI) is a variant coronary artery resulting from bifurcation of the left main coronary artery (LMCA) [1]. Generally, it is diagnosed on autopsy [2]. Recently, RI has increasingly been observed by computed tomography angiography (CTA) of the coronary artery [3,4,5].

What does the Ramus artery supply?

Although the ramus intermedius can supply a large volume of myocardium, it is usually much less than that supplied by the left anterior descending, left circumflex, or right coronary arteries, and instead is similar to that supplied by a proximal diagonal or obtuse marginal branch.

Is the Ramus part of the LAD?

Overview. If an artery arises from the left main coronary artery between the left anterior descending artery (LAD) and the left circumflex artery (LCX), it is known as the ramus intermedius.

Where is the Ramus vessel?

Ramus intermedius (RI) is a variant vessel arising from the left main bifurcation angle (LMBA). Haemodynamically, its presence increases coronary turbulence flow and reduces the endothelial shear stress.

How is triple vessel disease treated?

Coronary artery bypass graft (CABG) is the treatment of choice in patients of diabetes with triple vessel disease (TVD). If the patient has TVD but is asymptomatic, the dilemma is whether to continue with medical management or to opt for revascularization.

How long can you live with triple vessel disease?

The basic characteristics of the group and its medication are shown in a table (Table 1). Approximately 50% of the patients with three-vessel disease died before the end of the study. The 5-year survival rate was 88%.

How serious is triple vessel disease?

Three-vessel disease (3VD) represents the most severe form of coronary atherosclerosis. Patients with 3VD and/or left main stenosis are considered a high-risk group according to therapeutic guidelines. In comparison with less severe forms of CAD, 3VD has been consistently associated with worse long-term prognosis.

Does everyone have a Ramus?

The ramus intermedius is a variant coronary artery resulting from trifurcation of the left main coronary artery ¹. It is present in ~20% (range 15-30%) ^2-3 of the population.

Which artery is the most common to have blockage?

Although blockages can occur in other arteries leading to the heart, the LAD artery is where most blockages occur.

Which artery is the widow maker?

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.

What does Ramus mean in cardiology?

The ramus intermedius (RI) is a variant coronary artery resulting from bifurcation of the left main coronary artery (LMCA) [1]. Generally, it is diagnosed on autopsy [2]. Recently, RI has increasingly been observed by computed tomography angiography (CTA) of the coronary artery [3,4,5].

Where is the Ramus artery on the heart?

If an artery arises from the left main coronary artery between the left anterior descending artery (LAD) and the left circumflex artery (LCX), it is known as the ramus intermedius.

What percent of blockage requires a stent?

“For a cardiac stent procedure to qualify as a medical necessity, it is generally accepted that a patient must have at least 70% blockage of an artery and symptoms of blockage,” Justice Department attorneys wrote.

Is 90 heart blockage serious?

A blockage that obstructs 90 percent of an artery is like a ticking time bomb just waiting to cause a heart attack or stroke.

Is a blocked circumflex artery serious?

Significant narrowing of the circumflex artery leads to worse outcomes than right coronary artery narrowing in patients with anterior myocardial infarction treated invasively.

What are the 5 major coronary arteries?

Structure

• Left coronary artery (LCA) Left anterior descending artery. Left circumflex artery. Posterior descending artery. Ramus or intermediate artery.
• Right coronary artery (RCA) Right marginal artery. Posterior descending artery.

What vitamin removes plaque from arteries?

Niacin, or Vitamin B3, is the best agent known to raise blood levels of HDL, which helps remove cholesterol deposits from the artery walls.

Can you stent a 100% blocked artery?

“Patients typically develop symptoms when an artery becomes narrowed by a blockage of 70 percent or more,” says Menees. “Most times, these can be treated relatively easily with stents. However, with a CTO, the artery is 100 percent blocked and so placing a stent can be quite challenging.”

What are the symptoms of a blocked artery in the neck?

Symptoms

• Sudden numbness or weakness in the face or limbs, often on only one side of the body.
• Sudden trouble speaking and understanding.
• Sudden trouble seeing in one or both eyes.
• Sudden dizziness or loss of balance.
• Sudden, severe headache with no known cause.

What is trifurcation disease?

Trifurcating coronary artery disease is a complex atherosclerotic process involving the origin of one or more of three side branches arising from a main coronary artery vessel or trunk (MT), with or without involvement of the MT itself.

What is ostial occlusion?

Ostial disease, namely coronary ostial stenosis, is the occlusion of coronary ostium. Causing factors include atherosclerosis, syphilis, Kawasaki disease, and Takayasu's arteritis, etc.

What are Rami anatomy?

Two vertical portions (rami) form movable hinge joints on either side of the head, articulating with the glenoid cavity of the temporal bone of the skull. The rami also provide attachment for muscles important in chewing.

Can triple vessel disease be reversed?

Getting those arteries to widen and become flexible again might seem daunting, but you're far from powerless. You can absolutely prevent CAD from worsening, and with some hard work, you might even be able to reverse some of the damage, says Gregg Fonarow, MD.

What are the symptoms of triple vessel disease?

What are the symptoms of triple vessel disease?

• Chest pain.
• Shortness of breath.
• Fatigue.
• Confusion.
• Heartburn or choking feeling.
• Nausea or vomiting.
• Pain or discomfort in the upper areas of the body, such as back, jaw, neck, arms or shoulders.
• Dizziness or light-headedness.

What is the meaning of RCA in medical terms?

Right coronary artery (RCA).
