Background: Despite growing evidence of cardiovascular complications associated with novel 2019 coronavirus disease (COVID-19), there is little data regarding the performance of transthoracic echocardiography (TTE) and spectrum of echocardiographic findings in this disease. Methods: We performed a retrospective analysis of adult patients admitted to a quaternary care center in New York City between March 1st and April 3rd, 2020. Patients were included if they had a TTE performed during the hospitalization after a known positive diagnosis for COVID-19. Demographic and clinical data were obtained using chart abstraction from the electronic medical record. Results: Of 749 patients, 72 (9.6%) had a TTE following a positive SARS-CoV-2 PCR test. The most common clinical indications for TTE were concern for a major acute cardiovascular event (45.8%) and hemodynamic instability (29.2%). While most patients had preserved biventricular function, 34.7% were found to have a left ventricular ejection fraction (LVEF) ≤ 50% and 13.9% had at least moderately reduced right ventricular function. Four patients had wall motion abnormalities suggestive of stress-induced cardiomyopathy. Using Spearman rank correlation there was an inverse relationship between high sensitivity Troponin T and LVEF (rho = -0.34, p=0.006). Among 20 patients with prior echocardiograms, only two (10%) patients had a new reduction in LVEF of more than 10%. Clinical management was changed in eight (24.2%) of individuals who had a TTE ordered for concern for acute major cardiovascular event; and three (14.3%) in whom TTE was ordered for hemodynamic evaluation. Conclusions: This study describes the clinical indications for usage and diagnostic performance, as well as findings seen on TTE in hospitalized patients with COVID-19. In appropriately selected patients TTE can be an invaluable tool for guiding COVID-19 clinical management.
