The New Niche: Transcatheter Aortic Valve Explantation and the Key Issues Concerning the Heart Team.

The volume of transcatheter aortic valve implantation (TAVI) for treatment of isolated aortic stenosis has far surpassed surgical aortic valve replacement (SAVR). There has been a consequent increase in TAVI explantation, now the fastest growing cardiac surgical procedure. Transcatheter heart valve explantation can be technically complex, with higher perioperative morbidity and mortality than routine SAVR or valve-in-valve TAVI.

Identifying Royal College-accredited simulation centre research priorities across Canada.

To advance the field of health sciences simulation, research must be of high quality and would benefit from multi-institutional collaboration where centres can leverage and share expertise as well as work together to overcome limits to the generalizability of research findings from single-institution studies. A needs assessment in emergency medicine simulation has illustrated the importance of identifying research priorities in Canada. The main purpose of this study was to identify simulation research priority directions for Canadian simulation centres.

Current and future transcatheter aortic valve replacement valves.

Purpose Of Review: This review analyzes currently available commercial transcatheter aortic valve replacement (TAVR) valves as well as valves in investigational status and those in preclinical testing. The design features and clinical outcomes of the Edwards SAPIEN S3 and Medtronic Evolut PRO+ are described and compared with highlight clinical circumstances where one may be favoured over the other.

Recent Findings: Multiple randomized and nonrandomized trials have compared commercial and investigational TAVR valves.
