The fistula was giant and multiple, and was located in the right middle-lower lobe. Right to left shunt ratio was 27%, SO2 was 58.2%, %VC was 60%, mean pulmonary arterial pressure was 19 mmHg. Mitral regurgitation was mild (II). Ligation of the middle-lower branch of right pulmonary artery and the right lower pulmonary vein was performed through a median sternotomy.
