| Summary: | Aortic stenosis is a type of heart valve disease in which the aortic valve narrows and reduces blood flow to the heart. Without intervention, severe aortic stenosis can be fatal. Surgical aortic valve replacement (SAVR) is currently the recommended treatment for individuals with aortic stenosis who are low or intermediate surgical risk. For those who are at high surgical risk, transcatheter aortic valve implantation (TAVI) is standard care. However, improvements in the devices (catheters, balloons, and valves) used in TAVI have contributed to reduced risks of complications and improved outcomes. As result, there is growing interest in the use of TAVI in populations with severe, symptomatic aortic stenosis who are at low or intermediate surgical risk. As these persons would be potentially eligible for TAVI and for SAVR, the expanding use of TAVI in these populations introduces additional considerations about supporting patients' treatment decision making. The purpose of this report is to describe patients' and health care providers' experiences with and perspectives on TAVI, in particular issues relating to communication, treatment decision making, and reflections on experiences post-TAVI. Two sets of research questions guided this review: 1. How do people with aortic stenosis experience transcatheter aortic valve implantation (TAVI)? What are their perspectives on, expectations of, and preferences for TAVI? When making a decision about TAVI, what is involved and what do patients consider? What is their understanding of their health condition and the procedure? 2. How do health care providers who care for people with aortic stenosis experience TAVI? What are their perspectives on, expectations of, and preferences for communicating and supporting decision making around TAVI?
