Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Clinical indication for AVR for native valve predominant AR defined as:
  • Class I or II indication for AVR according to ACC/AHA or ESC/EACTS guidelines with moderate to severe or severe AR (Grade ≥3+) on transthoracic echocardiography, transesophageal echocardiography or cardiac MRI as assessed by the core laboratory OR
  • AR severity that remains indeterminate despite core laboratory review of all imaging including at least one advanced imaging modality (TEE or cardiac MRI) AND evidence of left ventricular damage\* from AR with unanimous agreement from the local heart team, an independent clinical evaluation committee and the CRB that the symptomatic subject (NYHA II or greater) will benefit from SAVR for AR
  • The subject is a candidate for TAVR using the Trilogy THV system and SAVR using a commercially approved bioprosthetic heart valve
  • Subject and the treating physician agree that the subject will return for all required post-procedure follow-up visits
  • Subject meets the legal minimum age to provide informed consent based on local regulatory requirements

You may not qualify if:

  • Confirmed moderate (2+) or less AR severity by core laboratory evaluation
  • Estimated life expectancy of less than 24 months due to associated non- cardiac comorbid conditions
  • Subject is high-risk for SAVR as determined by the local heart team
  • Subject refuses SAVR as a treatment option
  • Subject refuses a blood transfusion
  • Subject is selected for aortic valve repair or aortic surgery
  • Marfan syndrome or other known connective tissue disease that would necessitate aortic root replacement/intervention
  • Subject unable to undergo pre-procedure CT scan analysis for annular sizing
  • Mitral or tricuspid disease, considered clinically significant, such that if randomized to surgery, repair or replacement would be expected.
  • Subject has a known hypersensitivity or contraindication to all anticoagulation/antiplatelet medications (or inability to be anticoagulated for the index procedure), nitinol, or sensitivity to contrast media which cannot be adequately pre-medicated
  • Hostile chest or conditions or complications from a prior surgery that would preclude safe reoperation (i.e., mediastinitis, radiation damage, chest wall abnormalities, adhesion of aorta or internal mammary artery (IMA) to the sternum)
  • Need for emergency surgery or TAVR for any reason
  • Cardiogenic shock manifested by low cardiac output, vasopressor dependence, or need for mechanical circulatory support
  • Ongoing sepsis or active infective endocarditis with ongoing antibiotic (including suppressive) therapy or positive blood cultures within 6 weeks
  • Cardiac resynchronization therapy (CRT) device implantation within 30 days of randomization
  • +38 more criteria
