Echocardiography showed the following: the heart was located in the left thoracic cavity, the atriumwas in the normal position, the positions of the PA and the aorta were abnormal, the aorta had widened and moved forward, and both the heart and PA started from the functional SV. A tortuous tube with no echo was seen between the left PA and the descending aorta, with a length of 15 mm. There was noventricular septum,the internal diameter of the SV was 58.2 mm (Figure 4). CDFI revealed thatthe regurgitation area of the tricuspid valve orifice was 3.1 cm 2, the flow rate was 4.1 m/s, and the PG was 66 mm Hg.
