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.
