Creation of medially-based arterial flaps for coronary artery translocation
A site on the pulmonary artery for the left and right coronary anastomoses were chosen. This neoaortic location was higher than the top of the sinus of valsalva, to avoid tension/kinking/waisting of the coronary arteries and to avoid distortion of the aortic valve. Two medially based pulmonary arterial flaps as described by Roger Mee were created accordingly. The sites chosen allowed for rotation of the mobilized coronary buttons through an angle not more than 30°. No portion of the pulmonary arterial wall was excised.
