Abstract
Background:The use of transesophageal echocardiography (TEE) is controversial in patients with COVID-19. The aim of this case series was to demonstrate the usefulness of transesophageal echocardiography in acute cardiovascular care settings in patients with COVID-19 infection.Materials and Methods:We enrolled 13 patients with confirmed SARS-CoV-2 infection admitted to the critical care unit of our center from April 1, 2020, to July 30, 2020, in which transesophageal echocardiography was performed. TOE was performed by three cardiologists with training in echocardiography.Results:The main indication was suspected infective endocarditis in four cases, venovenous extracorporeal membrane oxygenation cannulation in four cases, suspected prosthetic mitral valve dysfunction in two patients, suspected pulmonary embolism in two patients, and acute right ventricular dysfunction and prone position ventilation in one patient. The final diagnosis was confirmed in 11 patients and discarded in 2 patients. None of the operators result infected.Conclusions:TOE is safe in the context of COVID-19 infection; it must be performed in well-selected cases and in a targeted manner.
