The selection of transcatheter heart valves in transcatheter aortic valve replacement.

Transcatheter heart valve technology has rapidly progressed since initial approval in the United States. There are currently two widely available transcatheter heart valve delivery systems approved in the US; however limited data exist on optimal device selection for various patient populations. This review explores the characteristics of currently approved transcatheter heart valve systems and scenarios where one valve system may be favored over others.

Effect of a virtual self-management intervention for atrial fibrillation during the outbreak of COVID-19.

Background: As the pandemic continues to unfold, effective, technology-based solutions are needed to help patients with atrial fibrillation (AF) maintain their health and well-being during the outbreak of COVID-19.

Methods: This single-center, pilot study investigated the effects of a 4-week (eight sessions) virtual AF self-management program. Questionnaires were completed at baseline and 1 week after the intervention, and assessed AF knowledge, adherence to self-management behaviors, mental health, physical function, and disease-specific quality of life in patients with AF.
