The Prelieve Trial - Pilot Study to Assess Safety and Efficacy of a Novel Atrial Flow Regulator (AFR) in Heart Failure Patients
The Prelieve Trial - Pilot Study to Assess Safety and Efficacy of a Novel Atrial Flow Regulator (AFR) in Heart Failure Patients
This study aims to investigate safety and efficacy of the Occlutech® AFR device in patients
 with HFrEF (Heart failure with reduced ejection fraction) and HFpEF (Heart failure with
 preserved ejection fraction)
This study will enroll subjects with HFrEF or HFpEF, until a maximum of 100 patients have
 undergone implantation with the Occlutech® AFR device.

 Enrolled patients will be stratified according to their ejection fraction as either HFrEF
 (ejection fraction > 15% and <40 %) or HFpEF ( ejection Fraktion > 40 % to 70 %). It is
 planned to enroll at least 100 patients per stratification subgroup.
Inclusion criteria. Each patient must fulfill ALL of the following criteria and details:

 1. Age ≥18 years

 2. Heart failure resulting in NYHA class III or IV ambulatory

 3. Ongoing management of heart failure according to ESC (European Society of Cardiology)
 (15) -guidelines during previous ≥6 months

 4. Control with Arrhythmia with heart rate <110bpm

 5. Life expectancy of at least 1 year

 6. The patient should have the ability to fluently speak and understand the language in
 which the study is being conducted

 7. Written, informed consent by the patient for participation in the study and agreement
 to comply with the follow-up schedule

 8. Patient has had a successful Balloon Atrial Septostomy (BAS) procedure and is in a
 stable hemodynamic state, as assessed by the investigator

 9. LVEF > 15% and < 70%, EF measured via Echocardiography 9.1. And for LVEF > 40%
 (HFpEF): elevated NT-pro-BNP of > 125 pg/ml

 10. Elevated left ventricular filling pressure documented by 10.1. Either Pulmonary
 capillary wedge pressure (PCWP) or left ventricular end-diastolic pressure at rest >
 15 mmHg and greater then central venous preassure (CVP) 10.2. Or: End-expiratory
 >25mmHg at Exercise and CVP < 20 mm Hg

 11. Transseptal catheterization and femoral vein access is determined to be feasible

 Exclusion Criteria:

 1. Local or generalized sepsis or other acute infection(s)

 2. Any coagulation disorder, if clinically relevant in the opinion of the operator.

 3. Allergy to nickel and/or titanium and/or nickel/titanium-based materials, if not
 medically manageable

 4. Allergy to anti-platelet, -coagulant, or -thrombotic therapy, if not medically
 manageable

 5. Intolerance to contrast agents, if not medically manageable

 6. Participation in another medical trial testing a therapy less than 30 days before the
 intended AFR implantation procedure

 7. Trans-oesophageal echocardiography and / or use of general anaesthetic is
 contraindicated

 8. Breast feeding women

 9. Pregnancy

 Processes which would technically disturb the safe intervention as planned:

 10. Occluded inferior vena cava access

 11. History of ASD and/or atrial septal repair or closure device in place

 12. Intracardiac thrombus

 Clinical conditions:

 13. Moderate valvular diseases requiring therapy according to current ESC guidelines.
 Patients are eligible in case therapy is formally indicated but cannot be performed
 due to technical or medial reasons if the latter is confirmed in writing by the PI in
 mutual agreement with the heart team and Severe aortic stenosis with valve area <
 1.5cm² and Severe AR, TR or MR. Classification of severity of regurgitation should
 follow the definition provided in Lancelotti et al, Eur Heart J Cardiovasc Imaging
 2013 [22]

 14. Patients who has unstable and intractable angina pectoris

 15. Evidence of right heart failure defined as (by ECHO)

 1. Severe Right Ventricular Dysfunction (TAPSE < 14 mm)

 2. Severe Right Ventricular Dilatation (RV volume ≥ LV volume)

 3. Severe pulmonary hypertension (PASP > 60 mm Hg)

 16. Active malignancy

 17. Severe valve disease, or implanted mechanical valve prosthesis

 18. Congenital heart defect

 19. Large PFO with significant atrial septal aneurysm (bubble test shows more than 20
 bubbles)

 20. Inability to perform 6-minutes walking test

 21. Clinically relevant thrombocytopenia, thrombocytosis, leukopenia, or anemia

 22. Symptomatic carotid artery disease

 23. Mitral valve stenosis

 24. Has any condition that, in the opinion of the Investigator, might interfere with the
 Implantation, might affect the patients well-being thereafter or might interfere with
 the conduct of the study

 25. Systolic blood pressure of >170 mmHg, despite medical therapy

 26. Severe lung disease (causing PHT with systolic PAP >60mmHg)

 27. Pulmonary Hypertension (Systolic PAP >60mmHg)

 28. TIA or stroke within the last 6 months

 29. Scheduled for heart transplantation

 30. Bleeding disorders (INR > 2.0, Thrombocytes < 100.000, Hemoglobin <8.0 gr/dl)

 31. Myocardial infarction or percutaneous intervention or CABG (all within the last 3
 month) or indication for a coronary intervention

 32. Resyncronization therapy started within the last 6 months

 33. Aneurysm of the septum

 34. Hypertrophied Inter Atrial Septum (IAS) > 10mm depth

 35. Hypertrophic Obstructive Cardiomyopathy (HOCM) or infiltrative CM as cause of HF
