Study: Small Annuli Randomized to Evolut™ or SAPIEN™
Descrizione riassuntiva dello studio
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.

Intervento studiato
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.

Malattie studiate
Patients with symptomatic heart disease due to severe native calcific aortic stenosis and a small annulus suitable for transcatheter heart valve replacement therapy. The products used in this study are CE marked and approved for public use in patients with aortic stenosis. The products are used according to the authorization in Switzerland. Product names - Medtronic Evolut™ PRO, Evolut™ PRO+ and Evolut™ FX* transcatheter aortic valve systems (TAV systems, Transcatheter Aortic Valve) - Edwards SAPIEN 3 and SAPIEN 3 Ultra transcatheter heart valve systems (THV systems, Transcatheter Heart Valve) * Note: The Evolut™ FX system is commercially available in the United States. The Evolut™ FX system may be used when commercially available in Canada.
(BASEC)
1. The patient's estimated operative mortality risk as assessed by the local cardiology team is <15% at 30 days. 2. The patient has been diagnosed with severe aortic stenosis. 3. The area of the patient's aortic valve annulus is ≤430 mm2. 4. The patient is suitable for treatment with both Medtronic Evolut TAV and Edwards TAV systems used within the conduct of the trial. 5. The patient is suitable for TAVR via vascular access through the femoral artery. 6. The patient and the treating physician agree that the patient will return to the study center for all required follow-up appointments after the procedure. (BASEC)
Criteri di esclusione
1. The patient's estimated life expectancy is less than 2 years. 2. The patient has multiple narrowed coronary vessels and/or the patient has an unprotected left main coronary artery. 3. The patient is participating in another study that could influence the outcome of this study. 4. The patient requires an emergency intervention for any reason. 5. Treatment with Medtronic Evolut and Edwards TAV systems according to the instructions for use cannot be performed on the patient. 6. Other medical, social, or psychological circumstances that, in the investigator's discretion, exclude the patient from providing appropriate informed consent or from complying with the follow-up examinations required by the protocol. 7. The patient is pregnant, breastfeeding, or planning a pregnancy. 8. The patient is a minor, legally incompetent, unable to provide informed consent, or otherwise vulnerable. 9. The patient has an active COVID-19 infection or relevant history of COVID-19. 10. The patient has previously received an aortic valve replacement. (BASEC)
