1 The “Hinge-Twist” Technique for Anomalous Origin of the Left Coronary Artery 
Leo Lopez, MD, Laura Mercer-Rosa, MD, Evan M. Zahn, MD, Nolan R. Altman, MD, Renato Dubois, MD, Redmond P. Burke, MD  The Annals of Thoracic Surgery  Volume 82, Issue 2, Pages e19-e21 (August 2006) DOI: /j.athoracsur Copyright © 2006 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 (A) Preoperative computed tomography (CT) scan shows origin of the left coronary artery from the right sinus of Valsalva with an interarterial course (*) between the great arteries. (B) Postoperative CT scan shows normal origin and course of the left coronary artery (*) without kinking or stenosis. (Ao = aorta; RV = right ventricle.)

3 Fig 2 (A) Diagram of “hinge-twist” technique. (B) Transected aorta with a triangular pericardial patch creates a “hinge” next to the anomalous left coronary artery ostium (*). (C) Triangular pericardial patch in the ascending aorta to match the proximal aortic circumference and counter-clockwise rotation (“twist”) of the distal aorta to the right before aortic anastomosis. (Ao = aorta; AoV = aortic valve; LMCA = left main coronary artery.)
