A surgical case of unruptured giant sinus of Valsalva aneurysm with right ventricular outflow tract stenosis using double closure technique

抄録

We performed aneurysm repair with double closure technique of sinus of Valsalva aneurysm（SVA）in a 59-year-old man who was revealed obstructing right ventricular outflow tract（RVOT）with moderate Aortic insufficiency（AI）by transthoracic echocardiography（TTE）. SVA plication was performed resection and suture trans tricuspid valve. Patch closure was performed with double-layer 30mm×30mm bovine pericardial patch. Aortic valve cusps had no abnormalities such as prolapse and AI disappeared after aneurysm repair because the etiology of AI was enlargement of aortic valve annulus. He was discharged with good condition. Computed tomography confirmed disappearance of blood flow in SVA, and TTE showed released RVOT obstruction in follow-up. Double closure technique, which combines resection and suture and patch closure, is useful for treatment of SVA.
