Purpose Severely ill patients affected by coronavirus disease 2019 (COVID-19) develop circulatory failure. We aimed to report patterns of left and right ventricular dysfunction in the first echocardiography following admission to intensive care unit (ICU). Methods Retrospective, descriptive study that collected echocardiographic and clinical information from severely ill COVID-19 patients admitted to 14 ICUs in 8 countries. Patients admitted to ICU who received at least one echocardiography between 1st February 2020 and 30th June 2021 were included. Clinical and echocardiographic data were uploaded using a secured web-based electronic database (REDCap). Results Six hundred and seventy-seven patients were included and the first echo was performed 2 [1, 4] days after ICU admission. The median age was 65 [56, 73] years, and 71% were male. Left ventricle (LV) and/or right ventricle (RV) systolic dysfunction were found in 234 (34.5%) patients. 149 (22%) patients had LV systolic dysfunction (with or without RV dysfunction) without LV dilatation and no elevation in filling pressure. 152 (22.5%) had RV systolic dysfunction. In 517 patients with information on both paradoxical septal motion and quantitative RV size, 90 (17.4%) had acute cor pulmonale (ACP). ACP was associated with mechanical ventilation (OR > 4), pulmonary embolism (OR > 5) and increased PaCO 2 . Exploratory analyses showed that patients with ACP and older age were more likely to die in hospital (including ICU). Conclusion Almost one-third of this cohort of critically ill COVID-19 patients exhibited abnormal LV and/or RV systolic function in their first echocardiography assessment. While LV systolic dysfunction appears similar to septic cardiomyopathy, RV systolic dysfunction was related to pressure overload due to positive pressure ventilation, hypercapnia and pulmonary embolism. ACP and age seemed to be associated with mortality in this cohort. Supplementary Information The online version contains supplementary material available at 10.1007/s00134-022-06685-2.

Background: Need for catecholamines is frequent in COVID-19 patients, but the main echocardiographic patterns are unknown. The objective was to report the main echo patterns in critically-ill COVID-19 patients. Methods: Observational and descriptive study in consecutive COVID-19 patients admitted to the ICU between March 12 and May 8, 2020. Systematic critical care echocardiography (CCE) was performed and retrospectively analyzed off-line. Echo values are reported in the overall population and in patients who required catecholamine infusion during the first 2 days following admission (D1-2) or afterwards until day 7 (D3-7). Results: Of the 79 patients (78% male; median age 63 [56-71]; body mass index 29 [26-30]) included, 90% had at least 1 comorbidity. PaO2/FiO2 at admission was 85 [67-162] mmHg. 53% of patients were mechanically ventilated. ICU length of stay was 9 [5-16] days and mortality 34%. 134 echocardiographic studies were performed during the first week in 65 patients. Pulmonary artery acceleration time was decreased (77 [65-97] ms), suggesting pulmonary hypertension. All 39 patients (49%) who required catecholamine infusion underwent CCE and 25.6% had left ventricular (LV) systolic dysfunction, 28.2% acute cor pulmonale (ACP), 7.7% hypovolemia, and 38.5% vasoplegia. Modification of echo patterns was observed at D3-7, with less LV systolic dysfunction and more ACP, which was the most frequent pattern. Computed tomography pulmonary angiography in 6 patients with ACP indicated intrapulmonary thrombus in 4. Conclusion: Different echocardiographic patterns were observed during the first week following ICU admission in COVID-19 patients. ACP was frequent and often related to thrombus in the pulmonary circulation.
