The Evolving Role of Echocardiography During the Coronavirus Disease 2019 Pandemic.

Coronavirus disease 2019 (COVID-19) has been associated with a wide spectrum of cardiovascular manifestations. Since the beginning of the pandemic, echocardiography has served as a valuable tool for triaging, diagnosing and managing patients with COVID-19. More recently, speckle-tracking echocardiography has been shown to be effective in demonstrating subclinical myocardial dysfunction that is often not detected in standard echocardiography. Echocardiographic findings in COVID-19 patients include left or right ventricular dysfunction, including abnormal longitudinal strain and focal wall motion abnormalities, valvular dysfunction and pericardial effusion. Additionally, some of these echocardiographic abnormalities have been shown to correlate with biomarkers and adverse clinical outcomes, suggesting an additional prognostic value of echocardiography. With increasing evidence of cardiac sequelae of COVID-19, the use of echocardiography has expanded to patients with cardiopulmonary symptoms after recovery from initial infection. This article aims to highlight the available echocardiographic tools and to summarize the echocardiographic findings across the full spectrum of COVID-19 disease and their correlations with biomarkers and mortality.
