What does ostial LAD mean?

What does ostial LAD mean?

Abstract. Background: Ostial disease of the left anterior descending (LAD) or circumflex (LCX) coronary artery is a challenge for the interventionalist. Focal ostial stenting may result in incomplete lesion coverage or plaque shift into the adjacent vessel, creating left main equivalent disease.

Can the LAD artery be stented?

Coronary stenting (STENT) and left internal mammary artery bypass grafting of the LAD (LIMA-LAD) are other options that have been successfully used for single-vessel LAD disease. The optimal mode of revascularization for patients with isolated single-vessel LAD disease is unclear.

What is an ostial stent?

The Ostial Pro™ (Ostial Solutions, Inc., Kalamazoo, MI) is a new device designed specifically to aid in the precise placement of stents in aorto-ostial locations. The device consists of a nitinol wire with a distal cylinder which is slit, permitting removal of the device without compromising wire position.

What does ostial mean in cardiology?

An ostial lesion is defined as a lesion which begins within 3-5 mm of the origin of a major epicardial artery. Ostial lesions represent a challenge to the interventional cardiologist because they often involve the wall of the aorta, they are often calcified, they may not fully dilate and they are prone to restenosis.

What percent of blockage requires a stent?

By clinical guidelines, an artery should be clogged at least 70 percent before a stent should be placed, Resar said. “A 50 percent blockage doesn’t need to be stented,” he said.

Is LAD blockage serious?

The total blockage of the LAD artery is a serious problem that requires immediate treatment. Delayed treatment for a heart attack can lead to significant tissue damage and scarring. It can be life threatening or lead to permanent disability. Not all heart attacks start with crushing chest pain or arm numbness.

What percentage of LAD blockage requires a stent?

What is coronary ostial stenosis?

Coronary ostial stenosis is a rare but potentially serious sequela after aortic valve replacement. It occurs in the left main or right coronary artery after 1% to 5% of aortic valve replacement procedures. The clinical symptoms are usually severe and may appear from 1 to 6 months postoperatively.

What is an angioplasty?

A coronary angioplasty is a procedure used to widen blocked or narrowed coronary arteries (the main blood vessels supplying the heart). The term “angioplasty” means using a balloon to stretch open a narrowed or blocked artery.

What does the word ostial mean?

(ŏs′tē-ŭm) plural.ostia [L. ostium, a little opening] A small opening, esp. one into a tubular organ.

What causes ostial stenosis?

While most commonly due to atherosclerosis, it may also be caused by aortic arteritis, congenital webs or post-surgical complications following aortic valve replacement. Three cases of lethal ischemic heart disease are reported where occult ostial narrowing/occlusion was first identified at autopsy.
