    Abstract:
    Aneurysms of the sinus of Valsalva are characterized by dilatation of at least one of the three aortic sinuses. We experienced a case with unruptured aneurysm of the right sinus of Valsalva, in which serial imaging studies were useful in assessing a rare complication after surgical repair. An asymptomatic 75-year-old man underwent patch closure of the aneurysm orifice because of progressive enlargement of the aneurysm. The postoperative course was uneventful, and computed tomography (CT), performed a week after the patch repair, showed no leakage of contrast medium into the isolated aneurysm. Three months later, echocardiography showed decreased size of the aneurysm with heterogeneous echogenicity and possible blood flow in the aneurysm, findings suggestive of thrombus formation and a recurrent fistula. CT with contrast medium showed partial recanalization between the patched aneurysm and the right sinus of Valsalva. Follow-up echocardiography, performed 1 year after surgery, revealed neither definite aneurysm nor shunt flow of Valsalva. The present case highlights that non-invasive follow-up can be an alternative option when carried out with caution in selected patients with incomplete closure of Valsalva aneurysm.
