Structural valve degeneration is a common, unpreventable, and untreatable consequence of BHV implantation and is frequently characterized by leaflet calcification. However, 25% of BHV reoperations attributed to structural valve degeneration occur with minimal leaflet mineralization. This review discusses the noncalcific mechanisms of BHV structural valve degeneration, highlighting the putative roles and pathophysiological relationships between protein infiltration, glycation, oxidative and mechanical stress, and inflammation and the structural consequences for surgical and transcatheter BHVs.Women who become pregnant again following miscarriage or stillbirth are in a particularly vulnerable position as they grapple with uncertainty about the current pregnancy's viability and outcomes. In this study, we examine the types of uncertainty that emerge in pregnancy after loss (PAL) and how women manage that uncertainty. Framed by the theory of communication and uncertainty management, we thematically analyzed threads (N = 636) from the online discussion board Reddit, focusing on the specific subreddit community r/PregnancyAfterLoss. Themes of physiological, emotional, and social uncertainty dominated the PAL experiences of these online community members. Uncertainty management and coping strategies included direct information seeking, bracing, mantras, and accepting uncertainty as part of the PAL experience. Theoretical contributions of this study include an initial conceptualization of emotional uncertainty in health comm
