Conditions studied: Heart Failure

In brief

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.

Who can join

Age: 22 and older, up to 88. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• General Inclusion Criteria:
• Ischemic or non-ischemic cardiomyopathy and documented heart failure for at least 6 months (diagnosis of HF ≥ 6 months), regardless of ejection fraction.
• NYHA Class II heart failure (HF) subjects, documented at Baseline Visit regardless of ejection fraction, meeting both inclusion criteria in subsections (2a) and (2b) or NYHA Class III heart failure (HF) subjects, documented at Baseline Visit regardless of ejection fraction, meeting at least one inclusion criteria in subsections (2a) and (2b).
• Have a minimum of one (1) HF hospitalization or equivalent (HF Emergency Department Visit or HF Urgent Clinic Visit) within the last 12 months associated with signs/symptoms of congestion requiring treatment with intravenous (IV) diuretic. If Cardiac Resynchronization Therapy (CRT) device previously implanted, the HF hospitalization or equivalent must be ≥ 30 days after CRT implantation.
• Have a corrected* elevated outpatient Brain Natriuretic Peptide (BNP) level of at least 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 be used exclusively.
• Receiving maximally-tolerated medical therapy for heart failure as indicated per ACC/AHA or ESC Heart Failure Guidelines (guideline-directed medical therapy or GDMT), in the absence of contraindications and lack of availability. GDMT refers to those guideline-directed medical therapies having a Class I indication for use.
• For patient with heart failure and a reduced ejection fraction (HFrEF), GDMT includes a diuretic as needed for volume control, angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) or angiotensin receptor neprilysin inhibitor (ARNI), beta-blocker (BB), mineralocorticoid receptor antagonist (MRA), and SGLT2 inhibitor for at least 3 months prior 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 more than a 100% increase or 50% decrease in dose.
• For patient with heart failure and a preserved ejection fraction (HFpEF), GDMT includes a diuretic as needed for volume control and treatment of associated conditions (e.g., hypertension, atrial fibrillation) for at least 3 months prior 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 more than a 100% increase or 50% decrease in dose.
• Patients should also receive Class I recommended cardiac rhythm management device therapy. Specifically: if indicated by class I guidelines, cardiac resynchronization therapy (CRT), implanted cardioverter-defibrillator (ICD), or a pacemaker should be implanted at least 3 months prior to Baseline Visit. These criteria may be waived if a patient is clinically contraindicated for these 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 ESC Heart Failure Guidelines will supersede the above guidelines.
• Provide informed consent for study participation and be willing and able to comply with the required tests, treatment instructions, and follow-up visits.

You may not qualify if…

• 1. Age less than 22 (<22) or greater than 88 (>88) years old. 2. Subjects who are NYHA class IV and ACC/AHA stage D. 3. Subjects with evidence/history of a major cardiovascular or neurovascular event, such as an intra-cardiac thrombus or history of stroke, transient ischemic attack, systemic or pulmonary thromboembolism, deep vein thrombosis (DVT), within the last 6 months of Baseline Visit.
• Subjects with a resting systolic blood pressure <90 or >180 mmHg. 5. Left ventricular end-diastolic diameter (LVEDD) > 8cm. 6. Have an atrial septal defect or patent foramen ovale with more than trace shunting on color Doppler or intravenous bubble study or surgical or interventional correction of congenital heart disease involving atrial septum, including placement of a PFO or ASD closure device, and have a hypermobile septum or a septal aneurysm.
• Subjects with untreated severe valve lesions, which are indicated for surgical or percutaneous intervention, active valvular vegetations, atrial myxoma, hypertrophic cardiomyopathy with significant resting or provoked subaortic gradient, acute myocarditis, tamponade, or large pericardial effusion, constrictive pericarditis, infiltrative cardiomyopathy (including cardiac sarcoidosis, amyloidosis, and hemochromatosis), or congenital heart disease, as a cause of HF.
• Uncontrolled tachyarrhythmia or bradycardia (heart rate <45). 9. Intractable HF with resting symptoms despite maximal medical therapy (ACC/AHA HF Stage D), including subjects receiving continuous or intermittent outpatient IV vasoactive medications (e.g., IV inotropes, IV vasodilators), subjects treated with a ventricular assist device (VAD).
• Intolerant to ACE-I, ARB, or ARNI and beta-blocker medical therapy for subjects classified as HFrEF (EF ≤40%).
• The presence of an acute coronary syndrome (ACS), percutaneous coronary intervention (PCI), rhythm management system revision, lead extraction, or cardiac or other major surgery within the preceding 90 days.
• Subjects not eligible for emergency open-heart, thoracic or vascular surgery.
• Women of childbearing age. 14. Subjects with a life expectancy that is shorter than 12 months, or those who have received a cardiac transplant or are listed for cardiac transplantation and likely to be transplanted within 12 months of Baseline Visit.

• Subjects contraindicated for trans-septal puncture, TEE or ICE.
• Intra Procedural Exclusion Criteria:
• (Intra Procedural Exclusion Criteria will be determined immediately after intracardiac echocardiography or transesophageal echocardiography determination of left atrial anatomy and just before transseptal puncture) 26. Anatomical anomaly on TEE or ICE that precludes implantation of the V-LAPIM across the interatrial septum (Fossa Ovalis) including: Septal thickness at fossa > 5 mm, FO Dimension <16mm, ASD or PFO with more than a trace amount of shunting, intra-cardiac thrombus felt to be acute and not present on prior exams and abnormal septum, e.g., a hypermobile septum or a septal aneurysm.
