Fig 1 Coronary unroofing with transfer to medially based trapdoor flaps. (A) The aorta is divided well above the sinotubular junction. (B) Fine scissors are used to unroof the intramural segment of the coronary artery. (C) Each flap is elevated and excised cleanly using fine scissors or a blade. (D) The two coronaries are then excised with button tissue around each orifice and transferred, as usual, to medially based trapdoor flaps swung out from the front of the main pulmonary artery.

Fig 2 Pericardial hood technique. (A) The upper edge is sutured to a scooped out edge, cut into the front of the neoaorta at the correct level. (B) An oval patch of pericardium is fashioned to cover the large button, creating a complete anterior pouch.
