Case Reports
COVID-19 patient bridged to recovery with veno-venous extracorporeal membrane oxygenation.
In severe cases, the coronavirus disease 2019 (COVID-19) viral pathogen produces hypoxic respiratory failure unable to be adequately supported by mechanical ventilation. The role of extracorporeal membrane oxygenation (ECMO) remains unknown, with the few publications to date lacking detailed patient information or management algorithms all while reporting excessive mortality. ⋯ With proper patient selection and careful attention to hemodynamic management, ECMO remains a reasonable treatment option for patients with COVID-19.

Venovenous extracorporeal membrane oxygenation (VV-ECMO) is a therapeutic strategy for the coronavirus disease 2019 (COVID-19) induced acute respiratory distress syndrome (ARDS). There are inconclusive data in this regard and causes of VV-ECMO failure are not yet understood well. ⋯ Hypercoagulability state and oxygenator failure were the most main etiologies for VV-ECMO failure in our study. All patients with COVID-19 undergoing VV-ECMO should be monitored for such problems and highly specialized healthcare team should monitor the patients during VV-ECMO.

The coronavirus disease (COVID-19) has affected a large population across the world. Patients with cardiovascular disease have increased morbidity and mortality due to coronavirus disease. The burden over the health care system has to be reduced in this global pandemic to provide optimal care of patients with COVID-19, as well not compromising those who are in need of emergent cardiovascular care. ⋯ After reviewing a few available guidelines regarding cardiovascular surgery in COVID-19, we conclude to perform only those surgeries which cannot be deferred to a certain period of time, to reduce the burden of the health care system of the country, provide optimal care to patients with COVID-19, and to protect health care workers and cardiovascular patients from COVID-19.

Both coronavirus disease (COVID-19) and cardiac surgery have a negative impact on pulmonary function. This study aimed to determine the postoperative respiratory outcomes of patients with COVID-19 who underwent cardiac surgery. ⋯ Although early respiratory outcomes of asymptomatic COVID-19 patients who underwent early cardiac surgery appeared to be satisfactory, compared to the propensity-scored matched non-COVID group, the postoperative outcomes were worse, especially in the ICU readmitted patients. We suggest postponing cardiac operations unless the patient requires emergency surgery.

Venoarterial extracorporeal membrane oxygenation (VA-ECMO) is utilized as a life-saving procedure and bridge to myocardial recovery for patients in refractory cardiogenic shock. Despite technical advancements, VA-ECMO retains high mortality. This study aims to identify the clinical predictors of in-hospital mortality after VA-ECMO to improve risk stratification for this tenuous patient population. ⋯ In a large study of recent VA-ECMO patients, in-hospital mortality remains significant, but acceptable given the severe pathology manifested in this population. Identification of pre-ECMO predictors of mortality helps stratify high-risk patients when deciding on ECMO placement, prolonged support, and prognosis.
