简要总结

The purpose of this study is to conduct the initial clinical investigation of the Foldax Polymer Aortic Valve to collect evidence on the device's safety and performance. The study is anticipated to confirm successful clinical safety and clinical effectiveness with significant improvements in clinical hemodynamic performance.

详细描述

The Foldax Polymer Aortic Valve is indicated as a replacement for a diseased, damaged, or malfunctioning native aortic heart valve via open heart surgery. This is a first in human study conducted under US FDA's Early Feasibility Investigational Device Exemption and will enroll up to 40 patients. These patients will be followed up to 5 years after implantation.

入选标准

  • Is 18 years or older
  • Provide written informed consent prior to trial procedures after standard of care studies and tests indicate that the patient needs aortic valve replacement
  • Agrees to attend all follow-up assessments for up to 5 years and is willing to comply with specified follow-up evaluations for the FOLDAX Clinical trial
  • Diagnosed with symptomatic aortic valve disease (stenosis and/or regurgitation) where aortic valve replacement is recommended based on pre-operative evaluations

结局指标

主要结局

Primary Safety Endpoints: Surgical Valve Events Rate Assessment

时间窗: 12 months following patient enrollment completion

The rates of other events will be compared to clinical outcomes for surgically implanted heart valves reported in the literature. a. All-caused death b. Valve related death c. Valve-related reoperation d. Valve explant e. Hemorrhage f. All-cause reoperation g. Valve-related death

Primary Effectiveness Endpoint: New York Heart Association Improvement Assessment

时间窗: 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.

Primary Safety Endpoints: Objective Performance Criteria for Flexible Heart Valve Events Assessments

时间窗: 12 months following patient enrollment completion

The adverse events consistent with the Objective Performance Criteria (OPC), for flexible heart valves will be compared to those rates defined as acceptable levels in the standard. a. Thromboembolism b. Valve Thrombosis c. Major Paravalvular leak d. Major Hemorrhage e. Endocarditis

Primary Effectiveness Endpoint: Hemodynamic Performance Assessment

时间窗: 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.
