    INPUT: Interval placement a right pigtail catheter projecting over the right lower hemithorax and a left pigtail catheter projecting over the left lower hemithorax . Bilateral small pleural effusions , greater on the left , are new . Small left apical pneumothorax ( approximately 1 .5 cm ) and tiny right apical pneumothorax are new . No evidence of tension . Lung volumes remain low , with probable reduced aeration of the lungs compared to the prior exam . The heart is normal in size . Increased interstitial markings bilaterally likely reflect mild edema , overall similar to the prior exam . Right PICC line ends in the low SVC . Enteric feeding tube traverses the diaphragm and ends in the stomach . Median sternotomy wires appear intact and unchanged . Replaced valve is intact .
    OUTPUT:
    
1 . New small left apical and tiny right apical pneumothoraces . 2 . New small bilateral pleural effusions . 3 . Two newly placed chest tubes - projecting over the lower bilateral hemithoraces . 4 . Mild edema is unchanged .
