Transesophageal Echocardiographic Assessment in Patients with Severe Respiratory Distress due to COVID-19 in the Prone Position: A Feasibility Study.

Background and aim: Our aim was to assess the feasibility, safety, and utility of implementing transesophageal echocardiographic screening in patients with coronavirus disease-2019 (COVID-19)-related acute respiratory distress syndrome (ARDS), receiving mechanical ventilation (MV) and in prone position (PP). Methods: Prospective observational study performed in an intensive care unit; patients 18 years, with ARDS, invasive MV, in PP were included. A total of 87 patients were included. Results: There was no need to change ventilator settings, hemodynamic support, or any difficulties with the insertion of the ultrasonographic probe. Mean duration of transesophageal echocardiography (TEE) was 20 minutes. No displacement of the orotracheal tube, vomiting, or gastrointestinal bleeding was observed. Frequent complication was displacement of the nasogastric tube in 41 (47%) patients. Severe right ventricular (RV) dysfunction was detected in 21 (24%) patients and acute cor pulmonale was diagnosed in 36 (41%) patients. Conclusion: Our results show the importance of assessing RV function during the course of severe respiratory distress and the value of TEE for hemodynamic assessment in PP.

Usefulness of echocardiography to detect cardiac involvement in COVID-19 patients.

Coronavirus disease 2019 (COVID-19) outbreak is a current global healthcare burden, leading to the life-threatening severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, evidence showed that, even if the prevalence of COVID-19 damage consists in pulmonary lesions and symptoms, it could also affect other organs, such as heart, liver, and spleen. Particularly, some infected patients refer to the emergency department for cardiovascular symptoms, and around 10% of COVID-19 victims had finally developed heart injury. Therefore, the use of echocardiography, according to the safety local protocols and ensuring the use of personal protective equipment, could be useful firstly to discriminate between primary cardiac disease or COVID-19-related myocardial damage, and then for assessing and monitoring COVID-19 cardiovascular complications: acute myocarditis and arrhythmias, acute heart failure, sepsis-induced myocardial impairment, and right ventricular failure derived from treatment with high-pressure mechanical ventilation. The present review aims to enlighten the applications of transthoracic echocardiography for the diagnostic and therapeutic management of myocardial damage in COVID-19 patients.
