Two-view chest radiography revealed an enlarged cardiac silhouette, minimal bibasilar atelectasis, and appropriate placement of the pacemaker leads (Figure 1).
(a) Large circumferential pericardial effusion measuring 2.6 centimeters posteriorly, 1.5 centimeters anteriorly, and 1.8 centimeters at the apex with right atrial collapse and without right ventricular collapse. Significant inflow variation was noted across the mitral and tricuspid valves. Left ventricular ejection fraction was estimated at 55%. Mild concentric left ventricular hypertrophy was present. (b) Echocardiogram obtained the day after pericardial drainage demonstrates resolution of the pericardial effusion.

An echocardiogram demonstrated a large circumferential pericardial effusion with right atrial collapse (Figure 2). A follow-up echocardiogram was obtained one day after the procedure and demonstrated complete resolution of the effusion (Figure 2(b)).
Serum sodium level during the hospital stay. Rapid correction of hyponatremia was observed within 36 hours of pericardiocentesis.

Serum electrolytes were monitored and showed a gradual improvement of the hyponatremia; serum sodium had increased from 120 to 123 mEq/L on the first postoperative day and to 131 mEq within 36 hours of the procedure (Figure 3).
