Double outlet right atrium—A “bridge” across the bridging leaflets

Mal‐alignment between the inter‐atrial septum (IAS) and the inter‐ventricular septum (IVS) during cardiac embryogenesis results in abnormal atrioventricular (AV) connections ranging from doubleoulet left atrium (DOLA) to double outlet right atrium (DORA)1.
