Figure legends
Figure 1. A 13-year-old female SV patient combined with cavernous hemangioma.Two-dimensional echocardiography: four-cavity cardiac surface view showing the left ventricular cavity was the main cavity, and the right ventricular cavity was the residual cavity. LA, left atrium; LV, left ventricle; RA, right atrium; RV, right ventricle
Figure 2. A 41-year-old female SV patient combined with single atrium.Two-dimensional echocardiography: four-cavity cardiac surface view showing a functional single atrium and a SV; CDFI showing severe reflux in the common atrioventricular valve in the systolicstage. A, atrium; V, ventricle
Figure 3.A 13-year-old female SV patient combined with atrial septal defect.A,Two-dimensional echocardiography: four-cavity cardiac surface view showing the right atrium was enlarged, no atrioventricular valve was found in the left ventricular cavity parallel to the right atrium. B,CDFI showing severe reflux in the atrioventricular valve in the systolic stage. LA, left atrium; RA, right atrium;V, ventricle
Figure 4.A 39-year-old female SV patient combined with patent ductus arteriosus.Two-dimensional echocardiography: four-cavity cardiac surface view showing two normal-sized atriums and an SV. LA, left atrium; LV, left ventricle; V, ventricle
