Chest X-ray presentation. (A) Chest X-ray performed at the 8th day after birth, which showed the distorted catheter as well as enlarged heart shadow; (B) Chest X-ray performed after the removal of PICC and the performance of pericardiocentesis, and the heart shadows were greatly reduced.

A repeat chest X-ray showed that the catheter was distorted, and the heart shadow was enlarged with a cardiothoracic ratio of 0.67 (Figure 1A). A chest X-ray showed that the heart shadows were reduced, and the cardiothoracic ratio was 0.6 (Figure 1B).
Echocardiographic image in the apical four chamber view shows a large pleural effusion. Pericardial cavity fluid dark area were detected: 6.2 mm in the rear of posterior wall of left ventricle, 6.5 mm in front of anterior wall of right ventricle, 9.1 mm in front of apical part, 5.6 mm outside the lateral wall of left ventricle, 9.8mm outside the lateral wall of right ventricle, 6.3 mm under the inferior wall of right ventricle beneath xiphoid process. Light spot reflex were visible in pericardial cavity. Left ventricular ejection fraction was 53%. (A) Apex four-chamber view of the heart. (B) Parasternal four-chamber view of the heart.

The interventricular septum shifted to the left during inspiration and to the right during exhalation (Figure 2).
Features of pericardiocentesis and pericardial effusion. (A) Pericardiocentesis and pericardial indwelling drainage; (B) Milky-white fluid released through pericardial puncture.

The PICC was removed immediately, and pericardiocentesis was performed, which released 35 ml of milky-white PCE (Figure 3).
