Fig. 4.
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.
