Key Words: Left atrial isomerism Pulmonary artery thrombosis
A 40-year-old woman presented with respiratory distress. Clubbing fingers, hematocrit of 67% and oxygen saturation of 83% were noted. Echocardiography revealed double-outlet right ventricle and transposition of great arteries. Striking images were shown (Fig. 1
). The pulmonary artery pressure was 55/21 (38) mmHg. Antiplatelet, anticoagulant and regular phlebotomy were prescribed.
