Also in the PARTNER trial, patients with critical aortic stenosis after either surgical aortic valve replacement (SAVR) or TAVR showed decreased aortic valve gradients and increased effective orifice area (EOA) on echocardiography through 2 years of follow-up. [37] Univariate postimplantation echocardiographic predictors of death in the TAVR group were as follows:

  • Larger left ventricular systolic and diastolic volumes

  • Larger EOA

  • Greater aortic regurgitation

  • Decreased ejection fraction
