Reduced access to TAVR to treat aortic stenosis in Canada compared to the US may affect mortality risk

A new study has found substantial regional differences in access to transcatheter aortic valve replacement (TAVR) and patient outcomes between Ontario and New York State. New York residents had improved access to TAVR and improved outcomes compared to Ontario. Statistical modeling also indicated that the same New York residents would have had worse outcomes had they been treated in Ontario. Results are published in the Canadian Journal of Cardiology.
