V-LAP™ Left Atrium Monitoring systEm for Patients With Chronic sysTOlic & Diastolic Congestive heaRt Failure
V-LAP™ Left Atrium Monitoring systEm for Patients With Chronic sysTOlic & Diastolic Congestive heaRt Failure
The purpose of the trial is to evaluate the safety, usability and performance of the V-LAP™
 System in adult subjects with New York Heart Association (NYHA) Class III Heart Failure.
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.
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.
