Eligibility
Key inclusion criteria
1. Chronic symptomatic Heart Failure (HF) documented by the following:

1. New York Heart Association (NYHA) Class III/ambulatory class IV symptoms (Paroxysmal nocturnal dyspnea, Orthopnea, Dyspnea on mild or moderate exertion) at screening visit, and signs (e.g. any rales post cough, Chest x-ray demonstrating pulmonary congestion,) within past 12 months; AND
2. One hospital admission for which HF was a major component of the hospitalization within the 12 months prior to study entry (transient heart failure in the context of myocardial infarction does not qualify), or one emergency department visit with IV treatment for HF within the 12 months prior to study entry
2. Ongoing stable GDMT for HF (Class I, and IIa recommendations) according to the 2016 ACC/AHA Guidelines for the management of Heart Failure (with no significant changes [>100% increase or 50% decrease], excluding diuretic dose changes for a minimum of 3 months prior to screening), which is expected to be maintained without change for 6 months
3. Age = 18 years old
4. Reduced Left ventricular ejection fraction between 20% and 40% as documented by echocardiography, radio nuclide ventriculography, or MRI within the past 3 months
5. Elevated left atrial pressure with a gradient compared to right atrial pressure (RAP) documented by:

a. Resting end expiratory PCWP = 18 mmHg, and greater than RAP by = 5 mmHg
6. Subject has been informed of the nature of the study, agrees to its provisions and has provided written informed consent, as approved by the IRB
7. Subject is willing to comply with clinical investigation procedures and agrees to return for all required follow-up visits, tests, and exams
8. Trans-septal catheterization by femoral vein access is determined to be feasible
Minimum age
18 Years
Maximum age
No limit
Sex

2. NT-Pro BNP < 100 pg/mL (if in sinus rhythm), or <300 pg/mL (if in atrial fibrillation); or BNP < 70 pg/mL (if in sinus rhythm), or < 200 pg/mL (if in atrial fibrillation)
3. Myocardial infarction (MI) and/or percutaneous cardiac intervention within past 3 months; CABG in past 3 months, or current indication for coronary revascularization

4. Listed on transplant waiting list
7. Ability to perform the 6 minute walk Test >600m
8. Known clinically significant un-revascularized coronary artery disease, defined as: epi-cardial coronary artery stenosis associated with angina or other evidence of coronary ischemia.
9. History of stroke, transient ischemic attack (TIA), deep vein thrombosis (DVT), or pulmonary emboli within the past 6 months or recurrent DVT/pulmonary emboli
