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.

Background And Aims: Transcatheter aortic valve implantation (TAVI) has become a viable treatment option for patients with severe aortic valve stenosis across a broad range of surgical risk. The Nordic Aortic Valve Intervention (NOTION) trial was the first to randomize patients at lower surgical risk to TAVI or surgical aortic valve replacement (SAVR). The aim of the present study was to report clinical and bioprosthesis outcomes after 10 years.

Background: When implementing new interventions into clinical practice, it is of great importance to investigate the implementation process to better understand factors promoting and impeding the implementation to stimulate engagement and sustainability of the intervention. It is essential to consider perspectives both from the health professionals delivering the intervention and those receiving the intervention to be open to their suggestions for enhancing the dissemination and implementation of the intervention. The aim of the study was to evaluate adoption, acceptability and appropriateness of a person-centred group intervention (PCGI) from the perspectives of facilitators and participants with mental illness in mental health outpatient services right after delivery.

Background: Non-surgical management of rectal cancer relies on (chemo)radiotherapy as the definitive treatment modality. This study reports and evaluates the clinical high dose radiotherapy treatment plans delivered to patients with low resectable rectal cancer in a Danish multicenter trial.

Methods: The Danish prospective multicenter phase II Watchful Waiting 2 trial (NCT02438839) investigated definitive chemoradiation for non-surgical management of low rectal cancer.
