Demographic, clinical, and survival data were collected. The echocardiographic analyses revealed high frequencies of pericardial effusion (90.7%), increased left ventricular mass index (60.5%), elevated relative wall thickness (76.7%), and reduced left ventricular stroke volume index (LVSVi; 53.5%) and cardiac index (51.2%). Twenty-two (51.2%) patients died in the ICU. In multivariate Cox regression, the strongest predictor of in-ICU death was decreased cardiac index [hazard ratio (HR), 0.67, 95% confidence interval (CI), 0.45\u20130.98; P = 0.041], after adjusting for male sex, shock status, high-sensitivity cardiac troponin I, and N-terminal pro-B-type natriuretic peptide. Negative associations with mortality were observed for LVSVi (HR, 0.91, 95% CI 0.85\u20130.96; P = 0.002), tricuspid annular plane systolic excursion (HR, 0.74, 95% CI 0.64\u20130.84; P &amp;lt; 0.001), and S\u2032 (HR, 0.78, 95% CI 0.69\u20130.88; P &amp;lt; 0.001). Kaplan\u2013Meier analyses indicated that reductions in LVSVi, cardiac index, TAPSE, and S\u2032 were associated with a shorter survival time.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Pericardial effusion and increased ventricular mass in COVID-19 might indicate a swollen heart.
