Abstract:
Aortic stenosis has a high mortality rate in patients who do not receive aortic valve replacement. Previously, transcatheter aortic valve replacement (TAVR) was an intervention reserved for individuals deemed high-risk for surgery. Since that time, TAVR has increasingly been offered to lower risk patients, yet it is unclear whether TAVR will meet an acceptable cost-effectiveness threshold in this group. In this cost-effectiveness study, we employed a decision tree model with Monte Carlo probability sensitivity analysis to determine the incremental cost (in US$) per quality-adjusted life year (QALY) and life year (LY) of performing the TAVR procedure using the resource-intensive approach versus the minimally invasive strategy in high-risk surgical patients.
