Clinical Trial 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.

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.

8. Has renal insufficiency as determined by creatinine (S-Cr) level as = 1.5 mg/dl or endstage renal disease requiring chronic dialysis at screening visit

9. Has MRI or CT scan confirmed stroke, cerebrovascular accident (CVA) or transient ischemic attack (TIA) within 3 months (90 days) prior to planned valve surgery

10. Has acute myocardial infarction (Ml) within 30 days prior to planned valve surgery

11. Has life expectancy to less than 12 months

12. Diagnosed with hypertrophic obstructive cardiomyopathy (HOCM), except patients who have isolated subaortic muscular hypertrophy diagnosed at the time of surgery

13. Diagnosed with abnormal calcium metabolism and/or hyperparathyroidism

14. Echocardiographic left ventricular ejection fraction <25%

15. Echocardiographic evidence of an intra-cardiac thrombus or vegetation

16. Hemodynamic or respiratory instability requiring inotropic support, mechanical circulatory support, or mechanical ventilation within 30 days prior to planned valve surgery

17. Documented leukopenia (WBC < 4.0 x 103/µL), acute anemia (Hgb < 10.0 gm/dl or 6 mmol/L), thrombocytopenia (platelet count < 100 x103/µL) or history of bleeding diathesis or coagulopathy

18. Has prior organ transplant or is currently an organ transplant candidate

19. Current or recent participation (within 6 weeks prior to surgery) in another drug or device trial

20. Pregnant, lactating or planning to become pregnant during the duration of participation in trial

21. Currently incarcerated or unable to give voluntary informed consent

22. Documented history of substance (drug or alcohol) abuse within the last 5 years prior to implant

23. Requires concomitant left ventricular assist device (LVAD) placement, Impella placement, and/or intra-aortic balloon pump

24. Tests positive for an active infection with SARS-CoV-2 (COVID-19)

25. Currently diagnosed as uncontrolled diabetes mellitus (Random BLS > 300 mg/dl)

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	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
Primary	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	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
Secondary	Stroke	Assessment of patient experiencing a stroke verified by imaging and or physical exam	12 months following patient enrollment
Secondary	Transient Ischemic Attack	Assessment of patient having a TIA verified by imaging and or physical exam	12 months following patient enrollment
Secondary	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
Secondary	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
Secondary	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
Secondary	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
Secondary	Readmission	Patient readmission to the hospital post discharge measured by date/time	30 Days post procedure
