The orifice of the left coronary artery at the beginning of the right pulmonary artery could be seen by an incision of the pulmonary artery (Figure 2A). The left coronary artery was buttoned off from the pulmonary artery wall (Figure 2B), anastomosed to the corresponding position of the aorta without tension and distortion, and the right pulmonary artery and main pulmonary artery were repaired with an autologous pericardial patch.
