Patients at Intermediate Surgical Risk Undergoing Isolated Interventional or Surgical Aortic Valve Implantation for Severe Symptomatic Aortic Valve Stenosis

Patients at intermediate risk undergoing TAVR differ significantly from those treated with SAVR with regard to age and baseline characteristics. Isolated TAVR and SAVR were associated with an in-hospital mortality rate of 3.6%. In the propensity score analysis, there was no significant difference in 1-year mortality between patients with TAVR and SAVR.
