About this study

Official title: A Randomized Comparison of the EDWARDS INTUITY Valve System anD commErcially Available Aortic Bioprostheses in Subjects uNdergoing surgiCal Aortic Valve replacEment

The study purpose is to compare the EDWARDS INTUITY valve system with commercially available stented aortic bioprostheses, in patients requiring aortic valve replacement surgery with coronary artery bypass.

Read the detailed description

This is a randomized study comparing the cross-clamp time (XCT) and cardiopulmonary bypass time (CPBT) of the EDWARDS INTUITY valve system with any commercially available stented aortic bioprosthesis, in patients with logistic EuroSCORE 1 ≥ 6 undergoing elective surgical aortic valve replacement surgery with concomitant coronary bypass grafts.

Additionally, the aim is to gather sufficient data to quantify the effect size of short term patient benefit outcomes previously identified from literature and finally to explore additional healthcare resource utilization or health economic endpoints.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Average Subject Time Spent on Cardiopulmonary Cross Clamp

    Cardiopulmonary cross clamp time is the amount of time that the patient's aorta (blood vessel) is clamped by a surgical instrument used in cardiac surgery. This allows the normal blood flow to be sent to an artificial heart and lung machine to keep it at a constant temperature and oxygen level.

    Measured: At time of surgery, an average of 1.5 hours

  2. Average Amount of Time Subject Spent on Cardiopulmonary Bypass

    Cardiopulmonary bypass time is the amount of time that the patient's blood circulates through an artificial heart and lung machine during cardiac surgery.

    Measured: At time of surgery, an average of 2 hours

Secondary outcomes (25)
  1. Number of Participants With Change From Baseline in New York Heart Association (NYHA) Class at 2 Years.

    The New York Heart Association (NYHA) functional classification system relates symptoms to everyday activities and the patient's quality of life. Class I. Patients with cardiac disease but without resulting limitation of physical activity.

    Class II. Patients with cardiac disease resulting in slight limitation of physical activity. They are comfortable at rest.

    Class III. Patients with cardiac disease resulting in marked limitation of physical activity. They are comfortable at rest.

    Class IV. Patients with cardiac disease resulting in inability to carry on any physical activity without discomfort.

    Symptoms of heart failure or the anginal syndrome may be present even at rest.

    Measured: Baseline and 2 Years

  2. Subject's Average Mean Gradients (mmHg) Measurements Over Time.

    Mean gradient is the average flow of blood through the aortic valve measured in millimeters of mercury. Gradients are evaluated by echocardiography over time. Mean gradient values depend on the size and type of valve.

    Measured: 30 days, 3 Months, 6 Months, 1 Year, 2 Years.

  3. Subject's Average Peak Gradients (mmHg) Measurements Over Time.

    Peak gradient is the maximum value measured of flow of blood through the aortic valve as measured in millimeters of mercury. Gradients are evaluated by echocardiography over time.

    Measured: 30 days, 3 months, 6 months, 1 year, 2 year

  4. Subject's Effective Orifice Area (EOA) Measurement Over Time.

    Effective orifice area represents the cross-sectional area of the blood flow downstream of the aortic valve. Effective orifice area is evaluated by echocardiography over time.

    Measured: 30 days, 3 months, 6 months, 1 year, 2 year

  5. Subject's Effective Orifice Area Index (EOAI) Measurement Over Time.

    Effective orifice area index represents the minimal cross-sectional area of the blood flow downstream of the aortic valve divided by the person's body surface area. Effective orifice area index is evaluated by echocardiography over time.

    Measured: 30 days, 3 months, 6 months, 1 year, 2 year

  6. Amount of Aortic Valvular Regurgitation Over Time.

    Aortic valvular regurgitation occurs when the aortic valve in the heart does not close tightly allowing some of the blood that was pumped out of the heart to leak back into it. Aortic valvular regurgitation is evaluated by echocardiography over time. It is assessed on a scale from 0 to 4, where 0 represents no regurgitation and 4 represents severe regurgitation.

    Measured: 30 days, 3 months, 6 months, 1 year, 2 year

  7. Conversion of Edwards INTUITY Surgical Aortic Valve to Control During Surgery.

    Subjects randomized to the Edwards INTUITY group that were converted to the control group and received commercially available surgical aortic heart valves during surgery.

    Measured: Prior to Surgery

  8. Subjects Who Required a Thoracic Resternotomy Over Time

    Number of Subjects who had a surgical opening of their chest after their initial aortic heart valve surgery shown over various time points.

    Measured: 30 days, 3 Months, 6 Months, 1 Year, 2 Years.

  9. Subjects Who Received a Permanent Pacemaker Over Time.

    Number of Subjects who received a Permanent Pacemaker shown over various time points.

    Measured: 30 days, 3 Months, 6 Months, 1 Year, 2 Years.

  10. Subjects With a Major Paravalvular Leak (OPC) Over Time

    Number of subjects who experienced a Major Paravalvular Leak (OPC) shown over various time points.

    Paravalvular leak refers to blood flowing through a channel between the implanted artificial valve and the cardiac tissue as a result of inappropriate sealing.

    Paravalvular leak is evaluated by echocardiography over time. It is assessed on a scale from 0 to 4, where 0 = no leak, 1 = a trace leak, 2 = a mild leak, 3 = a moderate leak, and 4 = a severe leak. A major paravalvular leak (OPC)are any events of leak that required surgical intervention or were considered an serious adverse event.

    Measured: 30 days, 3 Months, 6 Months, 1 Year, 2 Years.

    Number of subjects who experienced Major Bleeding shown over various time points.

    Measured: 30 days, 3 Months, 6 Months, 1 Year, 2 Years.

  12. Subjects Who Experienced Respiratory Failure Over Time

    Number of subjects who experienced a Respiratory Failure shown over various time points. Respiratory failure happens when not enough oxygen passes from your lungs to your blood.

    Measured: 30 days, 3 Months, 6 Months, 1 Year, 2 Years.

  18. Subjects With a Thromboembolism Over Time

    The EQ-5D is a standardized questionnaire that asks subjects to rate themselves (no problems, some problems, extreme problems) on mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The scale is indexed and ranges from a minimum of 0.275 and a maximum of 1.000.
