Prenatal images of left hemitruncus in tetralogy of fallot with an absent pulmonary valve

摘要

Tetralogy of Fallot (TOF) associated with an absent pulmonary valve (APV) is a rare variant accounting for 3-6 % of all patients with TOF [7]. Although several cases of left hemitruncus (anomalous left pulmonary artery originating from the ascending aorta) in TOF with an APV have been described [2, 6], the prenatal diagnosis of this condition has not been reported previously.
