Fetal Transposition of the Great Arteries with a Normal Three-Vessel View: Report of Two Cases - Abstract
Transposition of the great arteries (TGA) affects approximately 2 in 10,000 live births. Babies with this lesion can have significant cyanosis, increased risk of hypoxic cerebrovascular events and death. Fetal diagnosis is important to ensure appropriate postnatal management. Most cases of TGA will have an abnormal three-vessel view on antenatal screening, which would prompt evaluation by echocardiography and prompt appropriate perinatal management. We report 2 unusual cases of TGA with normal three- vessel views that highlight the importance of evaluating outflow views.
