Transvenous coaxial coil occlusion of levoatriocardinal vein

The term levoatriocardinal vein (LACV) was coined by Edwards and DuShane (1), describing a vascular connection between the left atrium and the left innominate vein (an embryologic derivative of the cardinal system). LACV usually serves as an egress for the pulmonary venous blood to decompress the left atrium in obstructive left heart lesions (2). We reported a 20-year-old man who presented with oxygen desaturation and chest tightness due to LACV, which was recanalized 17 years after the total correction of congenitally corrected transposition (CCT) of the great arteries, subpulmonary ventricular septal defect (VSD), and supravalvular pulmonary stenosis (SVPS). We have briefly discussed the pathogenesis, hemodynamic interference, clinical manifestations, and management of LACV after bidirectional Glenn shunt (BGS).
