Key Points

  • The research focuses on the treatment of hemolytic paravalvular leak using anatomy-guided valve oversizing and overexpansion.
  • Anatomy-guided valve oversizing
  • Intentional overexpansion
  • Assessment of procedural success
  • Application in high-risk patients
  • Anatomy-guided valve oversizing improves treatment outcomes
  • Overexpansion contributes to procedural success
  • Demonstrated effectiveness in high-risk patient population

Abstract

Anatomy-guided valve oversizing, combined with intentional overexpansion, is pivotal to procedural success. This approach may be a viable treatment option for high-risk patients with recurrent PVL.
