Lung ultrasound (LU) is a useful tool for monitoring lung involvement in novel coronavirus (COVID) disease, while information on echocardiographic findings in COVID disease is to date scarce and heterogeneous. We hypothesized that lung and cardiac ultrasound examinations, serially and simultaneously performed, could monitor disease severity in COVID-related ARDS. ⋯ In COVID-related ARDS, the combined lung and cardiac ultrasound proved to be an useful clinical tool in monitoring disease progression and in identifying parameters (LU score and RV/LV ratio) able to risk stratifying these patients.

Observational Study
Role of ROX index in the first assessment of COVID-19 patients in the emergency department.
During the first outbreak of Coronavirus disease 2019 (COVID-19) Emergency Departments (EDs) were overcrowded. Hence, the need for a rapid and simple tool to support clinical decisions, such as the ROX index (Respiratory rate - OXygenation), defined as the ratio of peripheral oxygen saturation and fraction of inspired oxygen, to respiratory rate. The aim of the study was to evaluate the accuracy of the ROX index in predicting hospitalization and mortality in patients with a diagnosis of COVID-19 in the ED. ⋯ The ROX index < 22.3 was statistically related to higher 30-day mortality (AUC = 0.764, 95% CI 0.708-0.820, p < 0.001). Eight patients were discharged and returned to the ED within the subsequent 7 days, their mean ROX index was 30.3 (6.2; range 21.9-39.4) at the first assessment and 24.6 (5.5; 14.5-29.5) at the second assessment, (p = 0.012). The ROX index, together with laboratory, imaging and clinical findings, correlated with the need for hospital admission, mechanical ventilation and mortality risk in COVID-19 patients.

Patients with aspiration pneumonitis often receive empiric antibiotic therapy despite it being due to a non-infectious, inflammatory response. ⋯ Early antibiotic therapy for acute aspiration pneumonitis was not associated with in-hospital mortality, but was associated with a longer hospital stay and prolonged use of antibiotics.

A little is known about long-term hemodynamic performance of the transcatheter heart valves (THVs). The aim of the present study was to assess hemodynamic outcome, structural valve deterioration (SVD) and bioprosthetic valve failure (BVF) in patients treated with transcatheter aortic valve replacement (TAVR) five or more years ago. All consecutive patients treated at Bologna and Florence University Hospitals with TAVR between January 2008 and December 2013 were analyzed in a retrospective registry with regards to demographic, procedural and outcome data as well as follow-up data on mortality and echocardiographic characteristics. ⋯ The hemodynamic presentation was stenosis in most of the cases (12 patients). Late BVF was registered in 10 patients (3.13%) and this was mainly driven by transcatheter paravalvular leak closure (six patients) with subsequent good long-term outcome. Our results confirm that TAVR appears to be a long-lasting treatment strategy with low rates of structural valve degeneration and valve failure.
