Inclusion criteria
Inclusion criteria: Candidates for the study must meet ALL of the following inclusion criteria: 1. Chronic symptomatic heart failure (HF) documented by the following: a. Symptoms of HF requiring current treatment with diuretics for >= 30 days AND b. New York Heart Association (NYHA) class II if a prior history of > NYHA class II; OR NYHA class III, or ambulatory NYHA class IV symptoms (paroxysmal nocturnal dyspnea, orthopnea, dyspnea on mild or moderate exertion) at screening visit; or signs (any rales post cough, chest x-ray demonstrating pulmonary congestion,) within past 12 months; AND c. >= 1 HF hospital admission (with HF as the primary, or secondary diagnosis); or treatment with intravenous (IV); or the need for intensification of oral diuresis for HF in a healthcare 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. 2. Ongoing stable GDMT HF management and management of potential comorbidities according to the 2022 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 4 weeks prior to enrollment which is expected to be maintained for 6 months. Stable management includes a minimum period of 4 weeks post hospitalization for any cause, including treatment with IV diuretics. 3. Age >= 40 years old 4. Site determined echocardiographic LV ejection fraction >= 40% within the past 6 months, without documented ejection fraction = 25mm Hg, and greater than RAP by >= 5 mm Hg. 6. Site determined hemodynamic evidence of peak exercise PVR 4 cm; or b. Diastolic LA volume > 50 or LA volume index > 28 ml/m2 or c. Lateral e 10; or f. Septal E/e > 15 8. Subject has been informed of the nature of the study, agrees to its provisions and has provided written informed consent, approved by the IRB or EC 9. Subject is willing to comply with clinical investigation procedures and agrees to return for all required follow-up visits, tests, and exams 10. Trans-septal catheterization and femoral vein access to the right atrium is determined to be feasible by site interventional cardiology investigator.
