The inflammatory response to the virus carries a high mortality rate and can lead to a variety of cardiothoracic complications such as acute coronary syndrome, thromboembolism, and heart failure [1]. Here, we present a case of a young female who suffered cardiac tamponade (CT) from a pericardial effusion (PEEF) attributed to COVID-19 infection, which has only been described a handful of times in the literature. CASE PRESENTATION A 33-year-old female with a history of Down syndrome and morbid obesity presented with worsening dyspnea and fever for one week. Her initial oxygen saturation was 50% on room air, and bilevel noninvasive ventilatory support was initiated. Her viral PCR was positive for COVID-19. A computed tomography angiogram of the chest revealed small bilateral pulmonary emboli, diffuse ground-glass consolidations, and small bilateral pleural effusions. Her respiratory status continued to decompensate and she was placed on mechanical ventilation. She became hypotensive requiring vasopressor support. The following morning, an echocardiogram (TTE) revealed an ejection fraction of 40-45% and a new PEEF with early right ventricular diastolic collapse consistent with CT physiology. She underwent emergent pericardiocentesis, and 220 mL of bloody fluid was drained. PEEF studies revealed a glucose level of 186 mg/dL, LDH of 1380 U/L, and protein of 3.0 g/dL. Total nucleated count was 16,545/uL with 68% neutrophils. Gram stain showed a few white blood cells without organisms, and final bacterial, fungal, and acid-fast cultures were negative. A pericardial drain was left in place, but the procedure was complicated by a pneumothorax and a chest tube was placed. A follow-up TTE the next day revealed improvement of the PEEF without signs of CT. A repeat chest x-ray showed resolution of the pneumothorax. Unfortunately, the patient’s oxygenation and hemodynamic status continued to worsen. She eventually suffered cardiac arrest with pulseless electrical activity and succumbed to her illness. DISCUSSION: New knowledge regarding complications of COVID-19 infection is continually emerging. According to a February 2022 systematic review, only 30 cases of severe PEEFs with CT secondary to COVID-19 have been recorded. The mechanism by which PEEFs form is unclear. It is proposed that the entry of the virus into inflammatory cells causes a release of cytokines such as TNF-alpha, IL-1, IL-6, and IL-8. This resulting cytokine storm allows rapid inflammation and infiltration of fluid into the pericardial sac [1]. CONCLUSIONS: In a decompensated patient with COVID-19, a stat TTE should be obtained to rule out PEEF. Physicians must be cognizant of this uncommon yet highly fatal complication in unstable COVID-19 patients, as cardiac tamponade is a potentially reversible cause of cardiac arrest.
