Multicenter Study Observational Study
Management of patients with severe acute respiratory failure due to SARSCoV-2 pneumonia with non-invasive ventilatory support outside Intensive Care Unit.
COVID-19 has high mortality rate mainly stemming from acute respiratory distress leading to respiratory failure (ARF). Aim of the study was to evaluate the management of severe ARF due to COVID-19 pneumonia using noninvasive ventilatory support (NIVS), studying safety and effectiveness of NIVS. ⋯ NIVS is a safe and effective strategy in the treatment of severe ARF due to COVID-19 related pneumonia, that reduces mortality and length of hospital stay in the carefully selected patients.

The aim of this study was to provide an economic assessment of interventional vs. surgical aortic valve replacement in the context of cost-effectiveness. Aortic stenosis represents the most common form of degenerative valvular heart diseases. As life expectancy increases, an even emerging prevalence is expected. Over decades, surgical replacement was considered as the method of choice. Up to one third of the patients were not eligible for surgery, as their estimated peri-operative risk was too high. In the early 2000s a catheter-based technique has been developed, being an alternative treatment option for patients, considered to be inoperable. ⋯ We assume, that TAVR will not only be the method of choice for the treatment of aortic stenosis in many patients. As the valves are getting cheaper, TAVR might even be superior to conventional heart surgery from an economic point of view.

Transcatheter aortic valve implantation (TAVI) is a valuable treatment option for patients with reduced left ventricular ejection fraction (LVEF) and low-flow/low-gradient (LF/LG) aortic stenosis (AS). According to current literature, the presence of severe AS is unlikely in case of severely reduced LVEF and mean pressure gradient (meanPG) below 30 mmHg. However, a considerable number of patients presenting with typical clinical symptoms of severe AS, show gradients below 30 mmHg. We hypothesized, that these patients undergoing TAVI do have a measurable clinical benefit and an improved LVEF. ⋯ Based on our findings TAVI represents a valuable treatment option even in patients with LF/LG AS and PGmean below 30mmHg.
