From: Anomalous pulmonary venous drainage: a pictorial essay with a CT focus
Effects of a longstanding left-to-right shunt in patients with PAPVD. a Right superior pulmonary vein (RSPV) draining into the superior vena cava (SVC). Right sided pulmonary plethora is seen. b Right atrial dilatation, cardiomegaly and features of pulmonary oedema. Subsequent computed tomographic pulmonary angiography (CTPA) demonstrated a RSPV draining into the SVC with dilated right heart chambers. c Patient with anomalous right superior and middle pulmonary veins draining into the superior vena cava/right atrium confluence. A chest radiograph demonstrates cardiomegaly and central pulmonary artery dilatation secondary to long-term left-to-right shunt
