Fibrocalcific Embolism of Right Coronary Artery Combined with Aortic Valvular Stenosis / 대한흉부외과학회지

ABSTRACT

The main cause of ischemic heart disease combined with aortic valve disease is the systemic atherosclerotic process. Coronary artery embolism by a particle from the calcified aortic valvular tissue is very rare. A 73-year-old female patient was admitted due to chest tightness of recent onset. Two dimensional echocardiogram showed severe calcific aortic valve stenosis. Preoperative coronary angiogram exhibited a stenotic lesion at the distal right coronary artery, which seemed to be embolic in origin. The coronary embolus was removed through the coronary arteriotomy and then the arteriotomy site was repaired by onlay patch angioplasty technique. Aortic valve was replaced by a bioprosthetic valve. The embolus was reported as a fibrocalcified particle of diseased valve.
