About this study
Official title: A Prospective, Multicenter, Single-armed Trial That Aims to Evaluate the Safety and Efficacy of Transcatheter Artificial Aortic Valve and Transcatheter Artificial Heart Values Delivery System
The purpose of this study is to demonstrate that transcatheter artificial aortic valve and transcatheter artificial heart values delivery system is associated with a reduction of all-cause mortality in severe aortic stenosis or insufficiency patients who are high risk or ineligible for aortic valve replacement.
Read the detailed description
Aortic valve diseases is usually caused by rheumatic fever, congenital aortic valve structural abnormality or degenerative aortic valve calcification. Transcatheter aortic valve implantation (TAVI) has evolved as an alternative to surgical aortic valve replacement (SAVR) with now more than 50,000 implantations in patients with symptomatic severe aortic stenosis, who were considered to be at very high or prohibitive operative risk.
This project take the incidence of all-cause mortality at 12 months since TAVI as the primary endpoint to evaluate the safety and efficacy, then take the procedure success rate, device success rate, incidence of severe adverse events, device operative performance, prosthetic valve performance and quality of life to evaluate transcatheter artificial aortic valve and transcatheter artificial heart values delivery system of Ningbo Jenscare Biotechnology Co., Ltd. in clinical application.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Jenscare TAVIDevice
Jenscare TAVI and delivery system will implant a percutaneous bioprosthesis value, which is positioned in the native aortic valve, plays a role to control blood flow, and help your heart to work better. It may also shorten your recovery time to getting back to everyday activities.
| Study group | Role | What they receive |
|---|---|---|
| Jenscare TAVI | Experimental | Patients undergoing a Jenscare TAVI and delivery system Receives: Device: Jenscare TAVI |
What is being measured
The primary outcome is the main question the study is designed to answer.
All-cause mortality
Cumulative incidence of a combination of all cause death at 12 month after TAVI
Measured: 12 month
Secondary outcomes (10)
Procedure success rate
Documentation of no death occurred during or within 72 hours after TAVI, no conversion to conventional cardiopulmonary bypass, the value was placed in the correct anatomical position and achieve the desired effect

Device success rate
Documentation of the device was implanted successfully, placed in the correct anatomical position and achieve the desired effect
Measured: During the TAVI procedure
Incidence of severe adverse events
Documentation of the serious long-term complications, including mortality, stroke, transient ischemic stroke, myocardial infarction, dialysis and reinterventions
Measured: During the TAVI procedure and 3 days,7 days, 30 days, 3 months, 6 months, 12 months after TAVI
Assessment of device operative performance
Using the following measure (loading and releasing properties of artificial aortic valve; pushing, emptying, withdrawing, developing performance, fracture of the delivery system) that can be converted to utilities using an algorithm. Utilities range from 1 to 3, with 3 representing perfect performance, and 1 corresponding to the worst performance state.

Evaluation and improvement of quality of life
Measures 5 domains (mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) that can be converted to utilities using an algorithm. Utilities range from 0 to 1, with 1 representing perfect health, and 0 corresponding to the worst imaginable health state.
Measured: Preoperative and 30 days, 3 months, 6 months, 12 months after TAVI
Echocardiographic assessment of valve performance
Using the following measures: peak flow velocity
Measured: 30 days, 3 months, 6 months, 12 months after TAVI
Echocardiographic assessment of valve performance
Using the following measures: degree of aortic valve regurgitation
Measured: 30 days, 3 months, 6 months, 12 months after TAVI
