JACC Cardiovasc IntervPublished

  • Registry-based cohort study
  • propensity score adjustment
  • multivariable logistic regression

Findings consistent after propensity score adjustment and multivariable logistic regression

Authors' conclusion

Both SASEV and IASEV provide favorable and similar hemodynamic and clinical outcomes following ViV-TAVR.
