Figure 3: Morphology of fetal specimens. (a) Huge right atrium (RA) with congested liver with granular surface. (b) Dilated right ventricle (area between the right coronary artery and left anterior descending coronary artery). (c) Normally related great artery with left aortic arch, demonstrating dilated ductus arteriosus due to circular shunt. With normal great artery (A=Aorta and P=Pulmonary artery) relationship with small caliber pulmonary artery (*) (normal for the gestation) compared to dilated aorta. D=Dilated ductus. (d) Large heart with severe pericardial effusion in situ with under developed thymus superiorly placed in the anterior mediastinum. (e) Right atrium cut open shows dilated tricuspid valve annulus without cusp visibility and downward displacement of septal cusp. (f) Right ventricle cut open through pulmonary artery to lateral border of RV shows tethering of posterior leaflet
