Clinical Investigation for the Foldax Tria Aortic Heart Valve India

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.

Study Overview

• Status: Active, not recruiting
• Conditions: Aortic Valve Stenosis; Aortic Valve Disease; Aortic Valve Insufficiency; Aortic Valve Calcification
• Intervention / Treatment: Device: Foldax Tria Aortic Valve

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Primary Effectiveness Endpoint: Hemodynamic Performance Assessment	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.	12 months following patient enrollment completion
Primary Effectiveness Endpoint: New York Heart Association Improvement Assessment	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.	12 months following patient enrollment completion
Primary Safety Endpoints: Clinical Outcomes Event Assessment	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	12 months following patient enrollment completion

Secondary Outcome Measures

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