Chest radiography, electrocardiogram, and echocardiography on admission. A: Chest radiography reveals dilatation of the pulmonary artery, bilateral pleural effusions, and enlargement of the heart. B: Electrocardiogram suggests right ventricular hypertrophy. C: Doppler echocardiography shows flattening of the interventricular septum (left panel) and severe tricuspid regurgitation with a tricuspid regurgitation pressure gradient (TRPG) of >100 mmHg (right panel).

Her chest radiography revealed dilatation of the pulmonary artery and bilateral pleural effusions (Fig. 1A), and a dominant R wave in lead V1 on electrocardiogram (ECG) indicated right ventricular hypertrophy (Fig. 1B). Doppler echocardiography revealed severe tricuspid regurgitation with a tricuspid regurgitation pressure gradient (TRPG) of >100 mmHg and flattening of the interventricular septum, suggesting severe PH (Fig. 1C).
Chest radiography, electrocardiogram, and echocardiography during the chronic phase (7 months after admission). A: Chest radiography shows mild pulmonary artery dilatation without any pleural effusion. B: Electrocardiogram shows no sign of right ventricular hypertrophy. C: Doppler echocardiography shows mild flattening of the interventricular septum and mild tricuspid regurgitation with a tricuspid regurgitation pressure gradient (TRPG) of 46 mmHg.

The results of chest radiography, ECG, and echocardiography also suggested an improvement in her PH (Fig. 2).
