Study Summary

The objective of this study is to evaluate the safety and performance of the V-LAP System in subjects with New York Heart Association (NYHA) functional class II and III HF, irrespective of left ventricular ejection fraction.

Eligibility Criteria

Inclusion

Inclusion Criteria:

  1. Ischemic or non-ischemic cardiomyopathy and documented heart failure for atleast 6 months (diagnosis of HF ≥ 6 months), regardless of ejection fraction.

  2. NYHA Class II heart failure (HF) subjects, documented at Baseline Visit regardlessof ejection fraction, meeting both inclusion criteria in subsections (2a) and (2b)or NYHA Class III heart failure (HF) subjects, documented at Baseline Visitregardless of ejection fraction, meeting at least one inclusion criteria insubsections (2a) and (2b).

  3. Have a minimum of one (1) HF hospitalization or equivalent (HF Emergency DepartmentVisit or HF Urgent Clinic Visit) within the last 12 months associated withsigns/symptoms of congestion requiring treatment with intravenous (IV) diuretic. IfCardiac Resynchronization Therapy (CRT) device previously implanted, the HFhospitalization or equivalent must be ≥ 30 days after CRT implantation.

  4. Have a corrected* elevated outpatient Brain Natriuretic Peptide (BNP) level of atleast 300 pg/ml or an N-terminal pro-BNP (NT-proBNP) level of at least 1,500 pg/ml,according to local measurement, within 90-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 subject is on ARNI, NT-proBNP should beused exclusively.

  1. Receiving maximally-tolerated medical therapy for heart failure as indicatedper ACC/AHA or ESC Heart Failure Guidelines (guideline-directed medical therapyor GDMT), in the absence of contraindications and lack of availability. GDMTrefers to those guideline-directed medical therapies having a Class Iindication for use.
  • For patient with heart failure and a reduced ejection fraction (HFrEF), GDMTincludes a diuretic as needed for volume control, angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) or angiotensin receptorneprilysin inhibitor (ARNI), beta-blocker (BB), mineralocorticoid receptorantagonist (MRA), and SGLT2 inhibitor for at least 3 months prior to theBaseline visit. Drug doses, with the exception of diuretics, should be stablefor at least 1 month, where stability is defined as no more than a 100%increase or 50% decrease in dose.

  • For patient with heart failure and a preserved ejection fraction (HFpEF), GDMTincludes a diuretic as needed for volume control and treatment of associatedconditions (e.g., hypertension, atrial fibrillation) for at least 3 monthsprior to the Baseline visit. Drug doses, with the exception of diuretics,should be stable for at least 1 month, where stability is defined as no morethan a 100% increase or 50% decrease in dose.

  • Patients should also receive Class I recommended cardiac rhythm managementdevice therapy. Specifically: if indicated by class I guidelines, cardiacresynchronization therapy (CRT), implanted cardioverter-defibrillator (ICD), ora pacemaker should be implanted at least 3 months prior to Baseline Visit.These criteria may be waived if a patient is clinically contraindicated forthese therapies or refuses them and must be attested to by the investigator.

  • GDMT may change over time; the most current versions of the ACC/AHA or ESCHeart Failure Guidelines will supersede the above guidelines.

  1. Provide informed consent for study participation and be willing and ableto comply with the required tests, treatment instructions, and follow-upvisits.

Study Description

The trial is designed to demonstrate that the V-LAP™ implant can be positioned in the interatrial septum.

The V- LAP™ System is intended for wirelessly measuring and monitoring LAP. The V-LAP™ System is indicated for subjects with chronic symptomatic ACC/AHA Stage C.

Pressure-guided medical management of study participants, with the goal of reducing hospitalizations and improving quality of life, will be implemented using a physician-directed patient self-management approach.

V-LAP-PSM (Patient Self-management), Patient Guidance Application is a smartphone application that guides the patient on how to self-adjust the treatment, according to physician prescription, and when to approach the study investigator.

Safety will be monitored by the occurrence of adverse events throughout the trial.
