Impact of Mandatory Preoperative Dental Screening on Infective Endocarditis in Patients Undergoing Surgical Valve Replacement.

Background: Guidelines recommend preoperative dental screening (PDS) prior to surgical valve replacement (SVR) to reduce risk of prosthetic valve infective endocarditis (IE). Nonetheless, limited data support these recommendations.

Objectives: The objective of this study was to investigate the impact of mandatory preoperative dental screening (MPDS) on risk of IE in patients undergoing SVR.

Antithrombotic therapy following transcatheter aortic valve implantation: a Danish nationwide study.

Background: Antithrombotic therapy post-transcatheter aortic valve implantation (TAVI) has been widely debated in the past two decades. Data describing practice patterns of antithrombotic therapy are warranted. This study examined the trends in use of antithrombotic therapy post-TAVI in Denmark.

Bacteraemia after transcatheter aortic valve implantation: a nationwide cohort study.

Background: Bacteraemia and infective endocarditis (IE) are rare but severe complications of transcatheter aortic valve implantation (TAVI). Limited data exist on the incidence and microbiological profile of early bacteraemia in this population. This study aimed to evaluate the 6-month incidence of bacteraemia, IE and associated mortality following TAVI.

Randomized comparison of TAVI valves: The Compare-TAVI trial.

Introduction: Based on technical advancements and clinical evidence, transcatheter aortic valve implantation (TAVI) has been widely adopted. New generation TAVI valve platforms are continually being developed. Ideally, new valves should be superior or at least non-inferior regarding efficacy and safety, when compared to best-in-practice contemporary TAVI valves.

Effects of litter amount and seed sowing position on seedling emergence and growth of hemiparasitic Rhinanthus species under drought stress.

Roadside vegetation in Central Europe is mostly species-poor and dominated by a few grass species. Hemiparasitic plant species, including Rhinanthus spp., might effectively restrict grass growth, thereby making space for light-dependent herb species.
