Figure 1: (a) Chest radiograph (PA view) showing mild cardiomegaly and prominent shadow of LACV (arrows). (b) Angiogram in left anterior oblique view showing dilated innominate vein and LACV. The constriction in LACV is well above the joining of LUPV. (c) Line diagram depicting details of venous anatomy and relevant dimensions for the interventional closure of LACV. (d) Left pulmonary artery follow-through angiogram during venous phase showing well positioned device and normal flow in LUPV. (e) Echocardiogram 1 day after the procedure showing device (star) in situ and unobstructed flow in LUPV. (f) Chest radiograph (PA view) on follow-up showing a reduction in the shadow corresponding to LACV. PA: Pulmonary artery; LACV: Levoatriocardinal vein; LUPV: Left upper pulmonary vein; ADO: Amplatzer duct occluder; Ao: Aorta; LA: Left atrium; LIJV: Left internal jugular vein; LMPV: Left middle pulmonary vein; RIJV: Right internal jugular vein; RLPV: Right lower pulmonary vein; RSVC: Right superior vena cava; RUPV: Right upper pulmonary vein
