iDataResearch data from 2017 indicates that about one third of the valve replacements were endovascular (60,000 out of 180,000), although this ratio is expected to expand in future years. Of the top hospitals that perform valve replacements on the Medicare population, some have “fully” embraced the TVR, such as Cedars Sinai, St. Francis Roslyn, and Morristown. These hospitals had over 55% of their valve replacement cases performed endovascularly. Others, such as Cleveland Clinic and the Mayo Clinic had fewer than 30% of their heart valve replacement cases as TVRs.
