Primary Outcome Measures

Name	Time	Method
Percentage of Subject's With Freedom From Device or Procedure Related Death and/or Reoperation at 1-year Post-implant.	1-year post-implant	Subject's freedom from device or procedure related death and/or reoperation at 1-year post-implant. Time to events were estimated by Kaplan-Meier method. A higher number means a better outcome.

Secondary Outcome Measures

Name	Time	Method
Percentage of Early Adverse Events	Percentage of events occurring within 30 days of procedure	Number of early adverse events occurring within 30 days of procedure divided by the total number of enrolled subjects times 100.
Subject's Average Mean Gradient Measurements Over Time.	Baseline, 30 days, 3 months, and annually thereafter for up to 5 years	Mean gradient is the average flow of blood through the aortic valve measured in millimeters of mercury. Gradients are evaluated by echocardiography over time. In general, a higher value is considered worse, and a lower value is considered better but the value is dependent on the size and type of valve.
Amount of Paravalvular Pulmonary Regurgitation in Subjects Over Time by Valve Size	Discharge, 30 days, 3 months, and annually thereafter for up to 5 years	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 represents no regurgitation/leak (a better outcome) and 4 represents severe regurgitation/leak (a worse outcome).
Number of Late Adverse Events Divided by Late Patient Years (Expressed as a Percentage) for the Trial Valve Cohort.	Events occurring ≥ 31 days and up through 5 years post implant.	Late patient years are calculated from 31 days post-implant to the date of the last follow-up visit (or contact) or adverse event. Late patient year calculation: \[(Number of late events/sum of late patient years) x 100\]
Subject's Average Peak Gradient Measurements Over Time.	Baseline, 30 days, 3 months, and annually thereafter for up to 5 years	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. In general, a higher value is considered worse, and a lower value is considered better but the value is dependent on the size and type of valve.
Subject's Average Doppler Velocity Index (DVI)	Baseline, 30 days, 3 months, and annually thereafter for up to 5 years	The Doppler Velocity Index (DVI) is a calculation of the ratio of the sub valvular velocity obtained by pulse wave Doppler and the maximum velocity obtained by continuous wave Doppler across the prosthetic valve, i.e. Time velocity interval (TVI) of the pulmonic valve / TVI of the RVOT. There are no normal ranges issued by the American Society of Echocardiography's Guidelines and Standards Committee for the pulmonary valve, however the expectation is that DVI should remain relatively steady over time but will generally decrease as the degree of stenosis (narrowing or constriction of the valve opening) worsens.
Change in Subject's New York Heart Association (NYHA)/Modified Ross Heart Failure Functional Class	Baseline, 30 days, 3 months, and annually thereafter for up to 5 years	The New York Heart Association (NYHA)/Modified Ross 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, shortness of breath. Class II. Slight limitation of physical activity. Comfortable at rest. Ordinary physical activity results in fatigue, palpitation, shortness of breath. Class III. Marked limitation of physical activity. Comfortable at rest. Less than ordinary activity causes fatigue, palpitation, or shortness of breath. 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. Changes in NYHA/Modified Ross HF classification from the preoperative baseline to the respective completed follow-up visits are shown as the number of subjects in each class who improved, worsened, or stayed the same.
Subject's Average Tricuspid Regurgitation (TR) Gradient Measurement Over Time.	Baseline, 30 days, 3 months, and annually thereafter for up to 5 years	Tricuspid regurgitation (TR) gradient (peak systolic) is defined as the maximum value measured of blood flowing back through the tricuspid valve during systole as measured in millimeters of mercury. In general, a higher value is considered worse, and a lower value is considered better but the value is dependent on the size and type of valve.
Subject's Average Peak Velocity Measurement Over Time	Baseline, 30 days, 3 months, and annually thereafter for up to 5 years	Peak velocity is defined as the maximum speed in meters per second that the blood is flowing through the pulmonic heart valve in a given direction. In general, a higher value is considered worse, and a lower value is considered better but the value is dependent on the size and type of valve.
Subject's Average Transvalvular Velocity Time Interval (VTI)	Baseline, 30 days, 3 months, and annually thereafter for up to 5 years	Transvalvular regurgitation velocity time interval (VTI) is defined as the measurement in centimeters of the blood flowing backwards through the tricuspid valve, averaged over time. There are no defined normal ranges for VTI. The VTI value is dependent on the function of the right ventricle of the heart (chamber within the heart that is responsible for pumping oxygen-depleted blood to the lungs) and the expectation is the value should be relatively steady over time.
Amount of Transvalvular Pulmonary Regurgitation in Subjects Over Time by Valve Size	Discharge, 30 days, 3 months, and annually thereafter for up to 5 years	Valvular regurgitation occurs when the 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. Valvular regurgitation is evaluated by echocardiography over time. It is assessed on a scale from 0 to 4, where 0 represents no regurgitation (a better outcome) and 4 represents severe regurgitation (a worse outcome).
