In a multicenter, retrospective analysis of 435 patients with refractory COVID-19 placed on V-V ECMO, cannulation by a single, dual-lumen catheter with directed outflow to the pulmonary artery was associated with lower inpatient mortality.

OBJECTIVE: To determine characteristics, outcomes, and clinical factors associated with death in patients with COVID-19 requiring extracorporeal membrane oxygenation (ECMO) support. METHODS: A multicenter, retrospective cohort study was conducted. The cohort consisted of adult patients (18 years of age and older) requiring ECMO in the period from March 1, 2020, to September 30, 2020. The primary outcome was in-hospital mortality after ECMO initiation assessed with a time to event analysis at 90 days. Multivariable Cox proportional regression was used to determine factors associated with in-hospital mortality. RESULTS: Overall, 292 patients from 17 centers comprised the study cohort. Patients were 49 (interquartile range, 39-57) years old and 81 (28%) were female. At the end of the follow-up period, 19 (6%) patients were still receiving ECMO, 25 (9%) were discontinued from ECMO but remained hospitalized, 135 (46%) were discharged or transferred alive, and 113 (39%) died during the hospitalization. The cumulative in-hospital mortality at 90 days was 42% (95% confidence interval [CI], 36%-47%). Factors associated with in-hospital mortality were age (adjusted hazard ratio [aHR], 1.31; 95% CI, 1.06-1.61 per 10 years), renal dysfunction measured according to serum creatinine level (aHR, 1.21; 95% CI, 1.01-1.45), and cardiopulmonary resuscitation before ECMO placement (aHR, 1.87; 95% CI, 1.01-3.46). CONCLUSIONS: In patients with severe COVID-19 necessitating ECMO support, in-hospital mortality occurred in fewer than half of the cases. ECMO might serve as a viable modality for terminally ill patients with refractory COVID-19.

IMPORTANCE: Cardiac tamponade requiring emergent intervention is a possible complication of coronavirus disease 2019 (COVID-19) infection. Favorable clinical outcomes are possible if timely management and drainage are performed unless ventricular failure develops. OBSERVATION: Cardiac tamponade in COVID-19, based on the limited reported cases, seems to be more common among middle-aged men with observed complications in black and ethnic minorities. Prognosis is worse amongst patients with concomitant ventricular failure. DESIGN AND METHODS: This is a case series of three COVID-19 patients complicated by cardiac tamponade, requiring surgical intervention at a single institution in New York. INTERVENTION: Pericardial window, Pericardiocentesis. OUTCOME: One patient had recurrence of cardiac tamponade with hemorrhagic component but fully recovered and was discharged home. Two patients developed cardiac tamponade with concomitant biventricular failure, resulting in death. CONCLUSION AND RELEVANCE: Cardiac tamponade with possible concomitant biventricular failure can develop in COVID-19 patients; incidence seems to be highest at the point of marked inflammatory response. Concomitant ventricular failure seems to be a predictor of poor prognosis.
