A giant pseudoaneurysm of the sinus of Valsalva with pulmonary artery obstruction.

Figure 2: An aortogram revealed a giant aneurysm (arrow heads) arising from the aortic root. There was extremely slow contrast filling and washout of the giant aneurysm (A and B). A right ventricular angiogram demonstrated obstruction at the main pulmonary artery (C). Emergent surgery was performed because of the patient’s severe condition. After opening the pericardium, a giant aneurysm with dark violet irregular surface became visible (D). The aneurysm was incised and the sinus of Valsalva was repaired by the Yacoub procedure. The post-operative course was uneventful. A: aneurysm; RV: right ventricle.
