Left chest cardiac device with lead tips projecting over the right atrium and right ventricle are similar to prior . Lung volumes are even lower than prior , causing bronchovascular crowding and accentuation of the cardiac silhouette . There is moderate pulmonary vascular congestion and mild edema . There is likely a is trace right and a moderate left pleural effusion . There is silhouetting of the left hemidiaphragm . Sternal wires are intact .
