ENVISION IDE Trial: Safety and Effectiveness of NAVITOR in Transcatheter Aortic Valve Implantation

NCT05932615 | Enrolling By Invitation DMC FDA Device

• 1 other identifier: ABT-CIP-10487
• Study Type: interventional
• Target: 1,500
• Locations: 2 countries
• Sites: 66

Brief Summary

The objective of ENVISION is to evaluate the safety and effectiveness of the Navitor Transcatheter Aortic Valve Implantation (TAVI) System for treating patients with symptomatic, severe native aortic stenosis who are considered intermediate or low risk for surgical mortality. The trial will also evaluate the safety and effectiveness of the Navitor TAVI System in a valve-in-valve (ViV) application in patients with symptomatic heart disease due to failure of a surgical or transcatheter bioprosthetic aortic valve who are at high or greater surgical risk.

Conditions

Aortic Valve Stenosis; Heart Valve Diseases; Aortic Valve Disease; Heart Disease Structural Disorder

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Subject who is deemed to be at intermediate or low risk for open surgical aortic valve replacement:
• Intermediate risk: estimated risk of overall surgical mortality ≥ 3% and \< 8% at 30 days
• Low risk: estimated risk of overall surgical mortality \< 3% at 30 days Estimated risk of overall surgical mortality includes consideration of the Society of Thoracic Surgeons (STS) risk score, overall clinical status, and other clinical co-morbidities unmeasured by the risk calculator
• New York Heart Association (NYHA) Functional Classification of II, III, or IV
• Degenerative aortic valve stenosis

You may not qualify if:

• In the opinion of the Investigator, life expectancy is less than 2 years
• Evidence of an acute myocardial infarction \[defined as ST-segment elevation myocardial infarction (STEMI) or non-ST-segment elevation myocardial infarction (NSTEMI) with acute ischemia symptoms and troponin elevation\] within 30 days prior to index procedure
• Untreated clinically significant coronary artery disease requiring revascularization
• Any percutaneous coronary or peripheral interventional procedure performed within 30 days prior (except pacemaker or implantable cardioverter defibrillator (ICD) implant) to index procedure or planned within 30 days following the index procedure
• Blood dyscrasias as defined: leukopenia (WBC \< 3000 mm3), acute anemia (Hb \< 9 g/dL), thrombocytopenia (platelet count \< 50,000 cells/mm³); history of bleeding diathesis or coagulopathy
• Active peptic ulcer or upper GI bleeding within 3 months prior to index procedure that would preclude anticoagulation
• Recent (within 6 months prior to index procedure date) cerebrovascular accident (CVA) or a transient ischemic attack (TIA)
• Renal insufficiency (creatinine \> 3.0 mg/dL or eGFR \< 30 ml/min/1.73m2) and/or end stage renal disease requiring chronic dialysis
• Hostile chest or conditions or complications from prior surgery that would make the subject be considered high surgical risk (i.e., mediastinitis, radiation damage, abnormal chest wall, porcelain aorta, adhesion of aorta or internal mammary artery to sternum, etc.)
• Significant frailty as determined by the heart team (after objective assessment of frailty parameters) that would indicate high or extreme surgical risk
• Mixed aortic valve disease (aortic stenosis and aortic regurgitation with predominant aortic regurgitation 3-4+)
• Aortic valve is a unicuspid or bicuspid valve as verified by echocardiography or CT.
• Severe ventricular dysfunction with LVEF \< 30% as measured by resting echocardiogram
• Pre-existing prosthetic heart valve or other implant (such as prosthetic ring or transcatheter edge-to-edge repair (TEER) clip) in any valve position
• Severe circumferential mitral annular calcification (MAC) which is continuous with calcium in the left ventricular outflow tract (LVOT)
