Acute or delayed mechanical valve fracture with possible migration is a rare problem seen after valve replacement. We report a patient where mechanical aortic valve leaflet detachment was encountered during implantation. The missing leaflet was retrieved in the left atrium at the level of the right lower pulmonary vein. This has not yet been described, and prompt recognition and intervention is warranted.

Right superior vena cava draining in the left atrium is a rare anomaly, commonly associated with other cardiac defects. Herein we present the case of a 9 year old patient, asymptomatic but with right heart dilation with sinus venous defect, bilateral superior vena cavas with the right draining into the left atrium.
