Extracorporeal Membrane Oxygenation for COVID-19-associated Severe Acute Respiratory Distress Syndrome in Chile: A Nationwide Incidence and Cohort Study.

The role of and needs for extracorporeal membrane oxygenation (ECMO) at a population level during the coronavirus disease (COVID-19) pandemic have not been completely established. To identify the cumulative incidence of ECMO use in the first pandemic wave and to describe the Nationwide Chilean cohort of ECMO-supported patients with COVID-19. We conducted a population-based study from March 3 to August 31, 2020, using linked data from national agencies.

Mediastinal mass presented 36 years after coronary bypass grafting: is vein graft pseudoaneurysm a differential diagnosis?

Saphenous vein graft aneurysm is a relatively rare but serious complication of coronary artery bypass grafting (CABG). The diagnosis of such cases is clinically challenging and requires a high index of suspicion, especially if presented atypically or very late after CABG. Herein, we report a case of a saphenous vein graft pseudoaneurysm that presented 36 years after CABG and was masquerading as a right atrial myxoma on serial echocardiograms over a 2-year follow-up period.
