Carpentier-Edwards PERIMOUNT Magna Ease Pericardial Bioprosthesis, Model 3300TFX

Edwards Lifesciences283 enrolled

Overview

The purpose of the study is to demonstrate the long term safety and effectiveness of the Carpentier-Edwards PERIMOUNT Magna Ease Valves in patients undergoing aortic valve replacement with or without concomitant procedures requiring cardiopulmonary bypass.

This is a prospective, single-arm, multi-center, interventional study to be conducted in the US and outside the US (OUS). This study will enroll a minimum of 225 patients implanted with the study valve in order to achieve 101 aortic valve replacement subjects each followed for a minimum of 8 years. The study will include male and female patients, 18 years or older, requiring replacement for a diseased, damaged or malfunctioning natural or prosthetic aortic valve. Patients will be followed and assessed after implant at discharge, 6 months, one year, and annually for a minimum of 8 years.

Outcomes

Primary Outcomes

Subject's Percentage of Long Term Safety Performance

Long term safety performance will be evaluated by comparing the linearized yearly rates to the objective performance criteria (OPC) referenced in the Food and Drug Administration (FDA) 1994 Draft Heart Valve Guidance. Expressed as the Number of late events divided by the total number of late patient years times 100. Late patient years are calculated from 31 days post-implant to the date of the last contact (follow up or adverse event).

Time frame: 31 days through 8 years post-implant

Number of Subject's in NYHA Functional Class I or II at 8 Year Post-Implant

Time frame: 8 years post-implant

Subject's New York Heart Association (NYHA) Functional Class at 8 Years Post-Implant Compared to Baseline

The New York Heart Association (NYHA) functional classification system relates symptoms to everyday activities and the patient's quality of life. Class I. No limitation of physical activity. Ordinary physical activity does not cause undue fatigue, palpitation, dyspnea (shortness of breath). Class II. Slight limitation of physical activity. Comfortable at rest. Ordinary physical activity results in fatigue, palpitation, dyspnea (shortness of breath). Class III. Marked limitation of physical activity. Comfortable at rest. Less than ordinary activity causes fatigue, palpitation, or dyspnea. Class IV. Unable to carry on any physical activity without discomfort. Symptoms of heart failure at rest. If any physical activity is undertaken, discomfort increases.

Time frame: 8 Years post-implant

Number of early adverse events occurring within 30 days of procedure divided by the number of enrolled subjects times 100.

Time frame: Events occurring within 30 days of procedure

Percentage of Late Adverse Events

Number of late events divided by the total number of late patient years times 100. Late patient years are calculated from 31 days post-implant to the date of the last contact (follow up or adverse event).

Time frame: Events occurring >= 31 days and up through 8 years post-implant

Percent of Subjects With Freedom From Serious Adverse Events (SAE) Post-implant > 30 Days

Subject's freedom from Serious Adverse Events at \> 30 days post-implant. Time to events were estimated by Kaplan-Meier method.

Time frame: 1 Year, 2 Years, 3 Years, 4 Years, 5 Years, 6 Years, 7 Years, and 8 Years post-implant

Subject's Average Peak Systolic Gradient (mmHg) Measurements at 8 Years Post-implant

Peak systolic gradient is the maximum value measured of flow of blood through the aortic valve as measured in millimeters of mercury. The data summary will be stratified by valve size.

Time frame: 8 years post-implant

Subject's Average Mean Systolic Gradient (mmHg) Measurements at 8 Years Post-implant.

Mean systolic gradient is the average flow of blood through the aortic valve measured in millimeters of mercury. Mean gradient values depend on the size and type of valve. The data summary will be stratified by valve size.

Time frame: 8 years post-implant

Subject's Average Effective Orifice Area Measurements at 8 Years Post-implant.

Effective orifice area represents the cross-sectional area of the blood flow downstream of the aortic valve. The data summary will be stratified by valve size.

Time frame: 8 years post-implant

Subject's Average Effective Orifice Area Index (EOAI) Measurements at 8 Years Post-implant.

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. The data summary will be stratified by valve size.

Time frame: 8 years post-implant

Subject's Average Performance Index Measurements at 8 Years Post-implant.

Performance index is defined as the subject's effective orifice area (the cross-sectional area of the blood flow downstream of the aortic valve) divided by the subject's native orifice area. The data summary will be stratified by valve size.

Time frame: 8 years post-implant

Subject's Average Cardiac Index Measurements at 8 Years Post-implant.

Cardiac index is an assessment that divides the cardiac output from left ventricle in one minute by the person's body surface area (BSA), thus relating heart performance to the size of the individual. The data summary will be stratified by valve size.

Time frame: 8 years post-implant

Subject's Amount of Aortic Valvular Regurgitation at 8 Years Post-Implant.

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.
