Meanwhile, a 12-lead electrocardiogram showed normal sinus rhythm with low voltage waves (Fig. 1).

The patient underwent a trans-thoracic echocardiogram (TTE), which showed a large fluid extrinsic collection present anteriorly, resulting in significant compression of the right atrium (RA) and ventricle, as well as the proximal right ventricle (RV) outflow tract (Fig. 2).

There appeared to be compression of the RA and ventricle (Fig. 3).

TTE showed resolution of the fluid collection and the RV normalized in size with normal systolic function with no RV collapse (Fig. 5), which was much improved as compared to the initial echocardiography at the time of presentation (Fig. 1). The patient was discharged on the sixth day of hospitalization in a stable clinical condition with a recommendation for close follow-up.
