Zusammenfassung der Studie

The aortic valve of a heart can narrow due to deposits (e.g., calcium, etc.) (aortic stenosis), making it difficult for blood to flow from the heart. An intervention to replace the diseased aortic valve is the standard treatment for aortic stenosis. This can be performed, among other methods, through a transcatheter aortic valve replacement (TAVR). In such an intervention, a flexible tube (catheter) containing the artificial heart valve is inserted through an incision in the skin at the groin and pushed through a blood vessel to the heart. No open-heart surgery is required. Patients for whom a TAVR is to be performed due to their aortic stenosis may participate in this study under certain conditions. If a patient is eligible for participation, they will receive either a commercially available self-expanding (SE) TAV from Medtronic or a balloon-expandable (BE) TAV from Edwards. The patient will be assigned to one of the two study groups (randomized). One group receives the self-expanding (SE) TAV from Medtronic and the other the balloon-expandable (BE) TAV from Edwards. Randomization means that a computer randomly assigns the patient to a group. Neither the patient nor the doctors can decide which group the patient will be in. For this study, data/information from the treatment routine will be collected. Additionally, electrocardiograms (recording of the electrical activities of the heart muscle fibers) and transthoracic echocardiograms (examination of the heart using a transducer placed on the chest) may be performed, and questionnaires may be administered that do not conform to the treatment routine but do not impose any additional burden on the patient.

Untersuchte Intervention

The purpose of this study is to obtain clinical insights into the valve safety and performance of the balloon-expandable (BE) compared to a self-expanding (SE) transcatheter aortic valve replacement (TAVR) in patients with a small aortic annulus and symptomatic severe native aortic stenosis.

Approximately 700 treated study participants at about 90 study centers in Canada, the European Economic Area, the Middle East, Africa, and the United States are expected to participate in the study.

Data from study patients will be collected at the following time points:

- Screening

- Baseline

- TAVR procedure

- Discharge

- 30 days and annually up to 5 years after the procedure

Data will primarily come from routine treatment. Additionally, electrocardiograms (recording of the electrical activities of the heart muscle fibers) and transthoracic echocardiograms (examination of the heart using a transducer placed on the chest) may be performed, and questionnaires may be administered that do not conform to the treatment routine but do not impose any additional burden on the patient.
