Figure 1 Straddling mitral valve in a patient with double outlet right ventricle and {S,D,D} segmental anatomy. (A) Subxiphoid long-axis view showing levocardia, situs solitus of the atria with a right-sided right atrium (RA), left-sided left atrium (LA), and D-ventricular loop. The mitral valve is seen entering the left ventricle (LV). (B) Cranial angulation of the transducer demonstrates straddling of the MV into the infundibulum (Inf). PA = pulmonary artery; S/A = superior/anterior; S/P = superior/posterior; R = right; TV = tricuspid valve.
