Atrial diversion

Apply a pericardial or polyester fabric to build a barrier in the right atrium, place it around the superior and inferior vena cava, and direct the blood of the vena cava (that is, systemic venous blood) to the tricuspid valve mouth into the left ventricle into the lungs Pulmonary venous blood is directed to the tricuspid valve orifice and enters the anterior right ventricle into the aorta. Although it anatomically complicates the deformity, it meets the requirements of physiological functions in hemodynamics.
