HLHS fetal autopsy heart specimen at 33.1 weeks of gestation. An autopsy heart specimen at 33.1 weeks gestation demonstrating decreased ratio of the diameter of the AO to that of the PA (a), severely underdeveloped LV and left atrial appendages in comparison with RV and right atrial appendages, with left superior vena cava (b), and aortic valve dysplasia, as well as an abnormal mitral valve along with shortened chordae and basal displacement of the papillary muscles, with the old clot deposition (c). A normal autopsy heart specimen at 33.5 weeks gestation as contrast (d). AO: aorta; RSVC: right superior vena cava; RAA: right atrial appendages; PA: pulmonary artery; LAA: left atrial appendages; RV: right ventricular; LSVC: left superior vena cava; LV: left ventricular; AV: aortic valve; and MV: mitral valve.
