Analysis of COVID-19 Patients With Acute Respiratory Distress Syndrome Managed With Extracorporeal Membrane Oxygenation at US Academic Centers.

ObjectiveThis study analyzed the outcomes of COVID-19 patients with ARDS who were managed with extracorporeal membrane oxygenation (ECMO) across 155 US academic centers.Summary background dataECMO has been utilized in COVID-19 patients with acute respiratory distress syndrome (ARDS) and refractory hypoxemia. Early case series with the use of ECMO in these patients reported high mortality exceeding 90%.MethodsUsing ICD-10 codes, data of patients with COVID-19 with ARDS, managed with ECMO between April and September 2020, were analyzed using the Vizient clinical database. Outcomes measured included in-hospital mortality, hospital and ICU length of stay, and direct cost. For comparative purposes, the outcome of a subset of COVID-19 patients aged between 18 and 64 years and managed with versus without ECMO were examined.Results1,182 patients with COVID-19 and ARDS received ECMO. In-hospital mortality was 45.9%, mean length of stay was 36.8 ± 24.9 days, and mean ICU stay was 29.1 ± 17.3 days. In-hospital mortality according to age group was 25.2% for 1 to 30 years; 42.2% for 31 to 50 years; 53.2% for 51 to 64 years; and 73.7% for ≥65 years. A subset analysis of COVID-19 patients, aged 18 to 64 years with ARDS requiring mechanical ventilation and managed with (n = 1113) vs without (n = 16,343) ECMO, showed relatively high in-hospital mortality for both groups (44.6% with ECMO vs 37.9% without ECMO).ConclusionsIn this large US study of patients with COVID-19 and ARDS managed with ECMO, the in-hospital mortality is high but much lower than initial reports. Future research is needed to evaluate which patients with COVID-19 and ARDS would benefit from ECMO

Left ventricular free wall rupture as a result of delayed presentation of an inferior ST-elevation myocardial infarction due to fear of COVID-19: case report.

BackgroundLeft ventricular free wall rupture (LVFWR) is a rare complication after myocardial infarction and usually occurs 1 to 4 days after the infarct. Over the past decade, the overall incidence of LVFWR has decreased given the advancements in reperfusion therapies. However, during the COVID-19 pandemic, there has been a significant delay in hospital presentation of patients suffering myocardial infarctions, leading to a higher incidence of mechanical complications from myocardial infarctions such as LVFWR.Case presentationWe present a case in which a patient suffered a LVFWR as a mechanical complication from myocardial infarction due to delay in seeking care over fear of contracting COVID-19 from the medical setting. The patient had been having chest pain for a few days but refused to seek medical care due to fear of contracting COVID-19 from within the medical setting. He eventually suffered a cardiac arrest at home from a massive inferior myocardial infarction and found to be in cardiac tamponade from a left ventricular perforation. He was emergently taken to the operating room to attempt to repair the rupture but he ultimately expired on the operating table.ConclusionsThe occurrence of LVFWR has been on a more significant rise over the course of the COVID-19 pandemic as patients delay seeking care over fear of contracting COVID-19 from within the medical setting. Clinicians should consider mechanical complications of MI when patients present as an out-of-hospital cardiac arrest, particularly during the COVID-19 pandemic, as delay in seeking care is often the exacerbating factor
