Subsequent left ventriculography revealed discrete stenosis of the sino-tubular junction and a narrowed proximal ascending aorta [Fig. 1].
Schematic diagram of the surgical technique: a The illustration shows the outer appearance before operation. b The incision line. c The ascending aorta is incised along the incision line. d The second and third incisions were enlarged using a trimmed ellipse patch respectively and the initial oblique incision was enlarged using fontanel shaped patch. e The illustration shows the outer appearance after operation

Finally, the initial aortic oblique incision was enlarged using a fontanel-shaped composite patch attached with a single running suture [Fig. 2].
Postoperative left ventriculography at 13 months after operation showed no stenosis in the ascending aorta and maintained of symmetry of the ascending aorta
