About this Study:

The purpose of this study is to evaluate initial clinical safety, device functionality and effectiveness of the Edwards Transcatheter Atrial Shunt System.
Eligibility Criteria:

  • Signed and dated IRB approved study consent form prior to study related procedures
  • ≥ 18 years old
  • Chronic symptomatic Heart Failure (HF) documented by the following:
    • NYHA class II with a history of NYHA class > II; NYHA class III; or ambulatory NYHA class IV AND
    • ≥ 1 HF hospital admission (with HF as the primary, or secondary diagnosis); or treatment with intravenous (IV) or intensification of oral diuresis for HF in a healthcare facility (emergency department/acute care facility) within the 12 months prior to study entry; OR an NT-pro BNP value > 150 pg./ml in normal sinus rhythm, > 450 pg./ml in atrial fibrillation, or a BNP value > 50 pg./ml in normal sinus rhythm, > 150 pg./ml in atrial fibrillation within the past 6 months.
  • In the judgment of the investigator, subject is on stable Guideline Directed Medical Therapy (GDMT) for heart failure and management of potential comorbidities according to current ACCF/AHA Guidelines and that is expected to be maintained without change for 3 months
  • Elevated LA (or PCWP) pressure of > 15 mmHg at rest or > 25 mmHg during supine ergometer exercise stress test, as measured at end-expiration; AND the LA (or PCWP) exceeds right atrial pressure (RAP) by > 5 mmHg at rest or > 10 mmHg during supine ergometer exercise stress test as measured at end-expiration
  • Willing to attend study follow-up assessments for up to 5 years
