Conclusions: AD and CVD are frequently associated. Further studies are needed in order to understand the effect of CVD and its risk factors on AD in order to better comprehend the effects of subclinical and clinical CVD on the brain. Finally, we need to clarify the impact of the underlying hypothesized mechanisms of this association and to investigate gender issues. PMID: 32454996 [PubMed]

Recent evidence shows that THV prostheses anchoring occurs at the raphe-level, known as LIRA plane, in raphe-type bicuspid aortic valve (BAV) disease. The purpose of this study was to evaluate the application of a novel supra-annular sizing method, known as Level of Implantation at the RAphe (LIRA) method, to optimize transcatheter heart valve (THV) prosthesis sizing in raphe-type BAV disease.

Rheumatic heart disease (RHD) still affects more patients globally than degenerative valve disease. The vast majority of these patients live in low- to middle-income countries. Once symptomatic, they will need heart valve surgery. Unfortunately, prosthetic valves perform poorly in these patients given their young age, the high incidence of multi-valve disease, late diagnoses and often challenging socio-economic circumstances.Notwithstanding the fact that better valve designs would ideally be available, ill-informed decision making processes between bioprosthetic and mechanical valves are contributing to the poor results.

ConclusionThese results demonstrate the establishment of a novel in vitro model for bacterial biofilm growth on porcine aortic roots mimicking IE. The model will allow to identify predilection sites of valves for bacterial adhesion and biofilm growth and it may serve as baseline for further research on IE therapy and prevention, e.g. the development of antimicrobial transcatheter approaches to IE.Graphic abstract

Transcatheter aortic valve implantation (TAVI) has revolutionized the management of patients with symptomatic severe aortic stenosis. Recently, the role of TAVI has expanded from the high surgical risk to low surgical risk patients.1-4 There are two commercially available transcatheter heart valve systems: self-expanding and balloon-expanding valves. In the pivotal trials comparing TAVI with surgical aortic valve replacement (SAVR), only one system was utilized in the individual trials.1,2,5-8 Studies providing a direct comparison between both devices are scarce.
