Aortic Valve Disease
Conditions
Brief summary
Collect real-world data on hemodynamic and clinical outcomes of the INSPIRIS RESILIA Aortic Valve, Model 11500A, in subjects requiring replacement of their native or prosthetic aortic valve as the only heart valve procedure during the index procedure, with or without other concomitant procedures.
Detailed description
Subjects in the INDICATE registry study will be enrolled at up to 20 sites in Germany. Up to 500 subjects will be implanted with the INSPIRIS RESILIA Aortic Valve in this registry.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Subject's average mean gradient measurement over time | Prior to discharge (an average of 7 to 10 days after surgery) and at 3 months | 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. |
| Subject's average peak gradient measurement over time | Prior to discharge (an average of 7 to 10 days after surgery) and at 3 months | 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 valve is considered worse, and a lower value is considered better, but the value is dependent on the size and type of valve. |
| Amount of aortic transvalvular regurgitation in subjects over time | Prior to discharge (an average of 7 to 10 days after surgery) and at 3 months | 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 by four categories, which are "no/trace leak", "a mild leak", "a moderate leak", and "a severe leak". A severe leak indicates a worsening outcome. |
| Amount of aortic paravalvular regurgitation in subjects over time | Prior to discharge (an average of 7 to 10 days after surgery) and at 3 months | 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 by four categories, which are "no/trace leak", "a mild leak", "a moderate leak", and "a severe leak". A severe leak indicates a worsening outcome. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Subject's New York Heart Association (NYHA) functional classification at 3 months as compared to baseline. | Baseline and 3 months | 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. |
