Prospective research is warranted to demonstrate the accuracy of these models in larger samples and different mitral annular phenotypes. 3DCMs could accurately predict post-TMVR neo-LVOT dimensions in a patient with a pre-existing mitral annular ring.

During the coronavirus disease 2019 (COVID-19) pandemic, health care workers (HCWs) have been obliged to wear personal protective equipment (PPE). We assessed the impact of PPE use on HCWs' physical health and we examined factors related to a greater risk of adverse events due to PPE use. We applied the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines and the Cochrane criteria. We searched PubMed, Medline, Scopus, ProQuest, CINAHL, and medRxiv from January 1, 2020 to December 27, 2020. Our review included 14 studies with 11,746 HCWs. The estimated overall prevalence of adverse events among HCWs was 78% with a range from 42.8% to 95.1% among studies. Among others, the following factors were related to the risk of adverse events among HCWs due to PPE use obesity, diabetes mellitus, smoking, pre-existing headache, longer duration of shifts wearing PPE, increased consecutive days with PPE, and increased exposure to confirmed or suspected COVID-19 patients. The frequency of adverse events among HCWs due to PPE use is very high. Healthcare facilities should take the necessary precautions and change the working conditions during the COVID-19 pandemic to prevent adverse events associated with PPE use and minimize harm to HCWs. The frequency of adverse
