Abstract:
Anomalous origin of one pulmonary artery from the aorta, or hemitruncus, is a rare cardiac malformation. We report a case of left hemitruncus (aortic origin of the left pulmonary artery) associated with tetralogy of Fallot diagnosed in utero. To the authors' knowledge, this is the first such case diagnosed by fetal echocardiography to be described in the literature. The condition was documented by postnatal echocardiogram and cardiac computed tomography. Prompt recognition of this lesion is essential for early repair to improve outcome.

Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
