Outcomes:
Case 1 developed cardiac tamponade without myocardial dysfunction. He developed recurrent cardiac tamponade that was drained, resulting in resolution of symptoms until discharge in stable condition.
Case 2 developed severe biventricular cardiac failure at the time of development of tamponade, resulting in immediate death.
Case 3 was admitted with AKI and worsening biventricular cardiac dysfunction, prior to pericardiocentesis that resulted in a progressive decline in hemodynamic status, ultimately leading to withdrawal of care.
