In this heart, Dextrocardia causes the whole heart to flip so the RA is on the patient’s left side and the LA is on the patient’s right side.
Also, the CCTGA causes just the ventricles to swap places. So, the LV is on the patient’s left side again and the RV is on the patient’s right side again.
Image: Atrioventricular Septal Defect topview cross section (Complete Atrioventricular Canal Defect). The tricuspid and mitral valves connect to each other instead of the septal wall. This creates one combined valve that leaks across all 4 chambers of the heart instead of 2 properly functioning valves.
