From: Short-term study of atrial shunt and improvement of functional mitral regurgitation
Color Doppler shows the shunt signal. A Echocardiogram showing D-shant atrial shunt discs tightly clamped on both sides of the atrial septum. Two-dimensional ultrasound findings are shown on the left and colour Doppler ultrasound findings are on the right. B Immediate left atrial pressure changes measured by catheterization after atrial shunt implantation in the atrial septum. C 3D transesophageal echocardiography (3D TEE) clear reconstruction of D-shant's left atrial disk slice. D The shunt orifice diameter of the D-shant was 0.6Â cm measured under 3D TEE
