The intraoperative view shows the pulmonary artery trunk originates from the right coronary artery (RCA), and the vascular wall of CPAF, which seems to be thinner than that of PA, and likely to be white.
RCA, right coronary artery; RVB, right ventricular branch; LCA, left coronary artery; aAo, ascending aorta; CPAF, coronary pulmonary artery fistula; MPA, main pulmonary artery; RPA, right pulmonary artery; LPA, left pulmonary artery.
