PURPOSE: Coronavirus disease 2019 (COVID-19) infection may trigger a multi-systemic disease involving different organs. There has been growing interest regarding the harmful effects of COVID-19 on the cardiovascular system. This systematic review aims to systematically analyze papers reporting echocardiographic findings in hospitalized COVID-19 subjects.

MATERIALS AND METHODS: We included prospective and retrospective studies reporting echocardiography data in >10 hospitalized adult subjects with COVID-19; from 1st February 2020 to 15th January 2021.

RESULTS: The primary electronic search identified 1120 articles. Twenty-nine studies were finally included, enrolling 3944 subjects. Overall the studies included a median of 68.0% (45.5-100.0) of patients admitted to ICU. Ten studies (34.4%) were retrospective, and 20 (68.9%) single-centred. Overall enrolling 1367 subjects, three studies reported normal echocardiographic findings in 49 ± 18% of cases. Seven studies (24.1%) analyzed the association between echocardiographic findings and mortality, mostly related to right ventricular (RV) dysfunction.

CONCLUSIONS: Data regarding the use of echocardiography on hospitalized, predominantly ICU, COVID-19 patients were retrieved from studies with heterogeneous designs, variable sample sizes, and severity scores. Normal echocardiographic findings were reported in about 50% of subjects, with LVEF usually not affected. Overall, RV dysfunction seems more likely associated with increased mortality.
