This research paper analyzes data from the STS/ACC TVT Registry, a large database that tracks transcatheter aortic valve replacement (TAVR) procedures in the United States, to examine trends in TAVR outcomes from 2019 to 2022. The study found that while unadjusted 30-day mortality remained stable during this period, risk-adjusted 30-day and in-hospital mortality increased modestly. This finding is concerning because it suggests that despite improvements in patient selection and procedural techniques, TAVR outcomes may not be continuously improving. Despite extensive investigation, the study was unable to identify any specific factors contributing to this trend. The authors suggest that future research is needed to identify the underlying causes and to ensure that these trends do not continue.
