A 16-year-old female patient in whom a biologic aortic valve
was implanted for bicuspid aortic valve, aortic stenosis with
aortic regurgitation one year ago and discharged uneventfully
was re-admitted to our clinic with dyspnea on exertion and
fatigue. Transthoracic echocardiography revealed valvular
aortic stenosis (a peak pressure gradient of 48 mmHg),
second degree aortic regurgitation and sinus valsalva
aneurysm. Multislice computed tomography angiography
produced an image which was associated with sinus valsalva
aneurysm at the subvalvular level or a pseudoaneurysm.
She underwent mechanical aortic valve replacement and
reconstruction of both valvular and subvalvular areas with
a Dacron patch. After an uneventful recovery stay in the
intensive care unit, the patient was discharged in the sixth
postoperative day. This case highlights the development of a
mitral-aortic intervalvular fibrosa pseudoaneurysm as a rare
complication of aortic valve replacement.
