Coronavirus Disease-2019 (COVID-19) has been associated with potentially life threatening cardiovascular complications, including fulminant myocarditis and cardiac tamponade. Optimal management strategies are still unclear, including the role of immunomodulatory therapies and extracorporeal membrane oxygenation (ECMO) in the context of cardiogenic shock. We report a case of a middle-aged female with COVID-19 who developed respiratory distress and hemodynamic deterioration with elevated troponin levels on the seventh day of symptoms. Echocardiography demonstrated pericardial effusion with diastolic restriction of the right ventricle. Cardiac arrest developed during pericardiocentesis, resulting in emergency thoracotomy and pericardial drainage. Venoarterial ECMO was subsequently initiated due to refractory cardiogenic shock. Tocilizumab, immunoglobulin, methylprednisolone and convalescent plasma were added to supportive care, with progressive recovery of cardiac function and successful weaning from mechanical ventilation. This case highlights the potential role of ECMO, convalescent plasma and immunomodulatory therapies in the management of cardiogenic shock associated with COVID-19 myopericarditis.
