Midline sternotomy wires are again noted. The heart is poorly assessed, though remains enlarged. There are at least small bilateral pleural effusions.  There may be mild interstitial edema. No pneumothorax. Bony structures are demineralized with kyphotic angulation in the lower T-spine again noted.  IMPRESSION: Limited exam with small bilateral effusions, cardiomegaly, and possible mild interstitial edema."
