What is proximal LAD disease?

What is proximal LAD disease?

Proximal left anterior descending coronary artery (LAD) lesions often supply a high percentage of the left ventricular myocardium, compared to proximal lesions in the circumflex or right coronary arteries.

What is proximal RCA?

RCA proximal: From the ostium to one half the distance to the acute margin of the heart. 2. RCA From the end of first segment to acute margin of heart. 3. RCA distal: From the acute margin of the heart to the origin of the posterior descending artery.

What is TVD disease?

Print. Tricuspid valve disease is a heart condition in which the valve between the two right heart chambers (right ventricle and right atrium) doesn’t work properly. Tricuspid valve disease often occurs with other heart valve problems.

What are the complicated lesions after atherosclerosis?

Ruptured plaques with overlying thrombus (type VI) are described as complicated lesions. When they achieve a significant degree of stenosis without sufficient collateralization, these lesions result in acute coronary syndromes (Fig. 2).

What are the chances of surviving a second heart attack?

Yet, about one in five people who have had a heart attack will be readmitted to the hospital for a second one within five years.

What is the initial lesion of atherosclerosis?

The earliest visible lesion of atherosclerosis is the fatty streak, which is due to an accumulation of lipid-laden foam cells in the intimal layer of the artery. With time, the fatty streak evolves into a fibrous plaque, the hallmark of established atherosclerosis.

What is the biggest contributor to heart disease?

High blood pressure, cigarette smoking, and high blood cholesterol are still major contributors to the national epidemic of cardiovascular disease.

What is proximal left anterior descending artery disease?

Proximal left anterior descending (LAD) coronary artery disease is considered as a high‐risk feature in interventional cardiology attributable to the large area of myocardium it supplies.

Is there a difference between proximal and nonproximal Lad angioplasty?

Evidence suggests that outcomes of proximal LAD angioplasty might not differ from treatment of nonproximal LAD locations. We aim to determine clinical outcomes of patients undergoing percutaneous coronary intervention in the proximal LAD segment in comparison with nonproximal LAD angioplasty, using a thin‐strut drug‐eluting stent.

Are there higher rates of PCI in proximal Lad?

Whether PCI of the proximal LAD segment is associated with higher rates of adverse events in comparison with nonproximal LAD PCI has been of interest.

What happens to the heart during a heart attack?

A heart attack generally occurs when there is a critical blockage in one or more of the arteries that supply the heart muscle with blood. Within minutes of the critical blockage occurring, the heart muscle stops working, and if blood flow is not restored within minutes to hours, the muscle typically dies. The consequences are often catastrophic.

What kind of heart attack is a proximal Lad lesion?

A proximal LAD lesion is a blockage in the left anterior descending artery, als known as the anterior interventricular artery. Explain why a heart attack caused by an obstruction of this artery is sometimes referred to as the “widowmaker” heart attack: The blood supply to the heart is by the way of the Coronary Arteries.

Can a blockage of the LAD artery cause a heart attack?

Blockage of the LAD artery Significant blockages of the LAD artery can be dangerous simply because the LAD supplies such a large territory. A stemi heart attack involving the LAD is typically more serious than other heart attacks. Usually a blockage of the LAD artery has to be more than 70% to cause significant problems.

What happens if you have a heart lesion?

A heart lesion is any stress or trauma delivered to the interior walls of the heart, resulting in tissue damage. This damage causes inflammation, which signals the body’s immune response. These dangerous lesions are the forerunner of a disease known as atherosclerosis.

Proximal left anterior descending (LAD) coronary artery disease is considered as a high‐risk feature in interventional cardiology attributable to the large area of myocardium it supplies.
