Abstract
|
|
|
Occlusion of a coronary artery ostium and especially occlusion of the right by an aortic cusp is a rare condition. We experienced an adult patient with occlusion of the right coronary ostium that was due to fusion of the right coronary cusp to the aortic wall along with underlying rheumatic aortic valve stenosis. During the operation, the adherent right coronary cusp was excised. After confirming that the right coronary ostium was patent, the other cusps were removed, and this followed by replacement of the aortic valve with a mechanical valve. The postoperative course was uneventful.
