Case Discussion

PAPVR is diversion of portion of the oxygenated blood from the left side of the heart to the right atrium through abnormal connection. This Left to Right shunt elicits volume overload on the right atrium and mixes the oxygenated with non oxygenated blood. Circumaortic left renal vein was another accidental finding. This is not related to the patient's original disease and discovered accidentally.
