Ultrasonography and autopsy correlation of fetal hypoplastic left heart syndrome

: Hypoplastic left heart syndrome (HLHS) represents a spectrum of abnormalities which marks the underdevelopment of left side cardiac structures. We present the ultrasound and autopsy correlation of two cases with HLHS with core pathology as isolated mitral atresia in one and aortic atresia in another. In both the cases after diagnostic confirmation on ultrasound (US), the couple opted for termination of pregnancy and consented for autopsy. The correlation of US and autopsy images of HLHS, facilitated our understanding of pathology behind the image obtained on US. The autopsy not only confirmed the antenatal diagnosis, but also added new findings.
