Intermittent dysfunction of prosthetic aortic valve is a rare, but life-threatening condition which may be difficult to recognize. The clinical presentation, include a severe acute ischemia due to the load/perfusion mismatch or heart failure. In this article, we report a case of intermittent dysfunction of prosthetic aortic valve in a 37-year-old female case who underwent Bentall operation five years ago for bicuspid aortic valve stenosis with ascending aortic aneurysm. An electrocardiogram showed sinus tachycardia with transient ST elevation in leads aVR and V1 and ST depression in leads I, II, III, aVF and V3-V6. Physical examination and laboratory results were normal but transthoracic echocardiography showed, a flap like pannus arising from the valve near the left main ostium. Coronary angiography showed normal coronaries. The patient was scheduled for surgery and a pannus was excised. Postoperative course was uneventful.
