Normal position of atrium, right ventricular loop. The left innominate vein was inferior to the aortic arch. The superior and inferior vena cava were in normal position into right atrium.
The right heart was plump, with thickening of right ventricular wall; the internal diameter of remaining atriums and ventricles were within normal range. Normal left ventricular wall motion amplitude
There was 8mm echo discontinuity in upper segment of interventricular septum。 CDFI: Bidirectional shunt signals were noted in ventricular level。
CDFI: Left to right shunt signal at fossa ovalis of interatrial septum, 2mm in width.
There was blind end in right ventricular outflow tract. Pulmonary valve and pulmonary trunk could not be detected. There was notable fusion and branches of pulmonary artery, measuring 3.7mm in internal diameter of the fusion. The development of left and right pulmonary artery branches was poor, measuring 1.5mm in internal diameter of left pulmonary artery and 2.2mm of right pulmonary artery. The aorta was overriding the interventricular septum, with the overriding rate of 40%.
CDFI: Minor amount of tricuspid regurgitation at systolic phase.
No evident abnormality of morphology of descending part of aortic arch, with formation of major aortopulmonary collateral vessel at descending part of aortic arch, measuring 3。5mm in greatest internal diameter at the aortic end。 CDFI: detectable blood flow signal in 2 phases。 CW: Vmax 231cm/s, PG 22mmHg。
1。 Congenital heart disease。
2。 Pulmonary artery atresia。
3. Ventricular septal defect.
4. Patent foramen ovale.
5。 The left innominate vein was inferior to the aortic arch。
6. Formation of major aortopulmonary collateral vessel.
