Figure

• 

  Fig. 1 Chest CT: a large, irregular, hypoattenuated mass in the RA (A), no abnormalities in pulmonary arteries (B). After cardiopulmonary resuscitation: no contrast enhancement of pulmonary arterial trees (C). Post-operative chest CT: complete visualization of pulmonary arteries (D).CT = computed tomography, RA = right atrium.

• 

  Fig. 2 Portable echocardiography: marked dilatation of the RV with free wall hypokinesia and a villo-papillary mass with irregular surface in the RA (A). Echocardiography at the time of pulseless electrical activity: no visualization of the mass (B).RV = right ventricle, RA = right atrium.

• 

  Fig. 3 Gross findings of the surgically removed masses from the pulmonary arterial trees (A). Histopathological examination confirmed the mass as myxomas (B).
