Not Applicable

Active, not recruiting

• Conditions: Aortic Valve Calcification; Aortic Valve Disease; Aortic Valve Stenosis; Aortic Valve Insufficiency
• Interventions: Device: Foldax Tria Aortic Valve

• Registration Number: NCT06192706
• Lead Sponsor: Foldax, Inc

Brief Summary

The purpose of this study is to conduct a clinical investigation of the Foldax Tria Aortic Valve to collect evidence on the device's safety and performance.

Detailed Description

The Foldax Tria Aortic Heart Valve is indicated as a replacement for diseased, damaged, or malfunctioning native aortic heart valve via open heart surgery. The study is a single open are label non-randomized multi- center clinical trial. Up to 10 sites in the country of India will enroll up to 50 patients. These patients will follow the study schedule for 1 year after implantation.

Group	Intervention	Description
Tria Aortic Valve	Foldax Tria Aortic Valve	Patients receiving the Foldax Aortic Valve

Primary Outcome Measures

Name	Time	Method
Primary Safety Endpoints: Clinical Outcomes Event Assessment	12 months following patient enrollment completion	The rate of adverse events will be compared to clinical outcomes for surgically implanted heart valves reported in the literature: a) thromboembolism, b) valve thrombosis, c) major paravalvular leak, d) major hemorrhage, e) endocarditis, f) all-caused death, g) valve related death, h) valve related reoperation, i) valve explant, j) hemorrhage, k) all-cause reoperation
Primary Effectiveness Endpoint: Hemodynamic Performance Assessment	12 months following patient enrollment completion	Hemodynamic performance parameters are mmHG mean gradient and derived Effective Orifice Area (EOA). Success is defined as clinically significant improvement in hemodynamic performance (Effective Orifice Area (EOA)) at one year based on literature reports for surgical aortic valve replacement.
Primary Effectiveness Endpoint: New York Heart Association Improvement Assessment	12 months following patient enrollment completion	Clinically significant improvement (one grade) in the New York Heart Association (NYHA) functional classification status at 365 days compared to baseline. a. Class I - No symptoms and no limitations in ordinary physical activity, e.g. shortness of breath when walking, climbing stairs etc. b. Class II - Mild symptoms (mild shortness of breath and/or angina) and slight limitation during ordinary activity. c. Class III - Marked limitation in activity due to symptoms, even during less-than-ordinary activity, e.g. walking short distances (20-100m). Comfortable only at rest. d. Class IV - Severe limitations. Experiences symptoms even while at rest. Mostly bedbound patients.

Secondary Outcome Measures

Name	Time	Method
Stroke	12 months following patient enrollment	Assessment of patient experiencing a stroke verified by imaging and or physical exam
Ventilation Time	30 Days post procedure	Ventilation time in hours defined as arrival time/date in recovery in hours and minutes to date and time extubated in hours and minutes
Change in Quality of Life (QOL)	12 Months post procedure	Change in QOL as measured by the Kansas City Cardiomyopathy Questionnaire
Length of Stay in Hospital	30 Days post procedure	Post procedure length of stay defined as the date and time in hours and minutes documented for arrival in the recovery unit to date and time in hours and minutes of discharge in hours and minutes.
Readmission	30 Days post procedure	Patient readmission to the hospital post discharge measured by date/time
Transient Ischemic Attack	12 months following patient enrollment	Assessment of patient having a TIA verified by imaging and or physical exam
ICU Duration of Stay	30 days post procedure	Length of stay in the ICU post valve implantation defined as arrival time/date in hours and minutes to transfer to floor time/date in hours and minutes.
Six Minute Walk Test (6MWT)	12 months post procedure	Change in distance walked during a 6MWT
New Onset Atrial Fibrillation	12 Months post procedure	New/post-operative atrial fibrillation - confirmed on ECG after closure during initial or subsequent admission or at one-year review
Hemolysis screen	12 Months post procedure	Hemolysis screen is measured by blood tests including hemoglobin and liver enzyme assessments
