Abstract
Although primarily a respiratory illness, coronavirus disease 2019 (COVID-19) has been associated with cardiac involvement with reported cases of myocardial ischemia, arrhythmia, myocarditis, pericarditis, and pericardial effusion leading to cardiac tamponade. Most cases of pericardial disease in this setting have been during the acute infection. Here, we present a patient who developed pericarditis leading to cardiac tamponade after the resolution of the acute COVID-19 infection. Her course of illness was further complicated by poor response to initial medical therapy with non-steroidal anti-inflammatory drugs (NSAIDs) and colchicine which could possibly be related to early exposure to steroids. It is often difficult to establish an underlying etiology for acute pericarditis. Similarly, in our case, although there is no definitive test to prove the causal relationship, this effusion is highly suspicious of being secondary to post viral sequelae after COVID-19 infection when considering the clinical course. It is important to consider pericardial disease as a late complication of COVID-19 even after apparent resolution of the acute infection and be mindful of the therapeutic challenges that we might face while managing such patients.
