; P<0.001) compared with term-born controls, with the severity of differences proportional to gestational age (r=−0.47, P<0.001). Differences in right ventricular mass and function were proportionally greater than previously reported for the left ventricle. This was most apparent for systolic function; young adults born preterm had significantly lower right ventricular ejection fraction (57±8% versus 60±5%; P=0.006). Indeed, 21% had values below the lower limit observed in the term-born adults and 6% had mild systolic dysfunction (<45%). Postnatal ventilation accounted for some of the variation in mass but not function. Conclusions-Preterm

The aim of this study was to characterize the echocardiographic phenotype of patients with COVID-19 pneumonia and its relation to biomarkers. Seventy-four patients (59 AE 13 years old, 78% male) admitted with COVID-19 were included after referral for transthoracic echocardiography as part of routine care. A level 1 British Society of Echocardiography transthoracic echocardiography was used to assess chamber size and function, valvular disease, and likelihood of pulmonary hypertension. The chief abnormalities were right ventricle (RV) dilatation (41%) and RV dysfunction (27%). RV impairment was associated with increased D-dimer and C-reactive protein levels. In contrast, left ventricular function was hyperdynamic or normal in most (89%) patients.
