Overview
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. A key issue in the treatment of an ostial lesion is to assure that the stent is inserted proximal enough to fully cover the aorto-ostial junction (particularly in the right coronary artery). Essentially the operator must realize that the aortic wall is being stented as well.
