Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The trial is designed to demonstrate that the V-LAP™ implant can be positioned in the interatrial septum, and that Sensor pressure measurements correlate to standardized methods of intra-cardiac pressure measurements post-sensor implant and at the 3 month follow up visit. Safety will be monitored by the occurrence of adverse events throughout the trial.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Ischemic or non-ischemic cardiomyopathy and documented heart failure for at least 6 months.
2. ACC/AHA Stage C, NYHA Class III or ambulatory Class IV HF documented at Baseline Visit.
3. Receiving maximally tolerated medical therapy for heart failure as indicated per ACC/AHA or ESC Heart Failure Guidelines (guideline-directed medical therapy or GDMT), such as diuretic, angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB), beta-blocker (BB), and mineralocorticoid receptor blocker (MRB) for at least 3 months prior to the Baseline visit.
4. Receiving rhythm management device therapy as recommended by the ACC/AHA or ESC Guidelines. Specifically: cardiac resynchronization therapy (CRT) should be implanted for at least 90 days prior to enrollment; an implanted cardioverter-defibrillator (ICD) or a pacemaker should be implanted at least 30 days prior to enrollment. If subject is clinically contraindicated for these therapies this criterion may be waived.
5. Have a minimum of one (1) prior hospital admission within the last 12-months for acute worsening of HF associated with signs/symptoms of congestion of at least one (1) calendar date change duration requiring treatment with an intravenous diuretic. If CRT device previously implanted, the heart failure hospitalization must be ≥ 30 days after CRT implantation. Alternatively, if patients have not had a HF hospitalization within the prior 12-months, they must have a corrected\* elevated Brain Natriuretic Peptide (BNP) level of at least 300pg/ml or an N-terminal pro-BNP (NT-proBNP) level of at least 1,500pg/ml, according to local measurement, within 30-days of the Baseline Visit. \*Thresholds for NT-proBNP will be corrected for body mass index (BMI) using a 4% reduction per BMI unit over 20 kg/m2, If patient is on ARNI, NT-proBNP should be used exclusively.
6. Provide informed consent for study participation and be willing and able to comply with the required tests, treatment instructions and follow-up visits.
