Ki nem vehet részt
Szó szerint a(z) ClinicalTrials.gov forrásból, témák szerint csoportosítva. Hogy ki vehet részt, azt csak a vizsgálat csapata dönti el.
Korábbi kezelés
- Documented history of stroke or transient ischemic attack (TIA) within the prior 6 months, or any prior stroke with a permanent major disability or deficit (National Institute of Health Stroke Scale [NIHSS] >1 at baseline)
- Planned to undergo any other open cardiac surgical or left heart interventional procedure (e.g., concurrent coronary revascularization) during the TAVR procedure or within 30 days prior to the TAVR procedure. The need for a postoperative pacemaker implant after TAVR is not exclusionary.
- History of intolerance, allergic reaction, or contraindication to any of the study medications, including heparin, aspirin, clopidogrel, or a sensitivity to contrast media or anesthesia that cannot be adequately pre-treated
- Currently participating in another drug or device clinical study
Más betegség
- Acute myocardial infarction (MI) within 30 days of the planned index procedure
- History of bleeding diathesis or major coagulopathy
- Hepatic failure (Child-Pugh class C)
- Known allergy to any materials used in the EmStop system (e.g., nitinol)
Laborértékek
- Left ventricular ejection fraction <30%, cardiogenic shock, or hypotension requiring inotropes or mechanical circulatory support, within 3 months prior to index procedure
- Renal failure, defined as estimated glomerular filtration rate (eGFR) <30 mL/min
- Active endocarditis or ongoing systemic infection, defined as fever (>38°C) and/or WBC >15,000 IU
- Known or suspected to be pregnant, or is lactating; women of child bearing age must have a negative serum or urine pregnancy test within 48 hours prior to the index study procedure
Egyéb
- Requires use of a balloon-expandable transcatheter aortic valve for the index procedure
- Hypercoagulable state that cannot be corrected by additional periprocedural heparin
- Undergoing therapeutic thrombolysis
- Vulnerable subject populations (e.g., incarcerated or cognitively challenged adults)
- Any other clinical reasons deemed by the investigators of the study in which the patient would not be an appropriate candidate for the study
A regiszterben nem jelölt feltételek
- Clinical Inclusion Criteria
- Age ≥ 22 years at the time of consent
- Meets FDA-approved indications for elective transfemoral self-expanding transcatheter aortic valve replacement (TAVR) procedure on a native or non-native (valve-in-valve) aortic valve. Note: Due to Neurologist availability and importance of capturing the neurological assessments, procedures must be performed Monday-Thursday.
- Left ventricular ejection fraction ≥ 30% as confirmed by echocardiogram
- Willing and able to provide written informed consent and written HIPAA authorization prior to initiation of study procedures
- Willing and able to comply with the protocol-specified procedures and assessments
- Imaging Inclusion Criteria
- Echocardiogram including left ventricular ejection fraction ≥ 30% within 6 months (180 days) prior to the index procedure and prior to randomization to confirm adequate cardiac function.
- Subjects must undergo a computed tomography angiography (CTA) scan within 6 months (180 days) prior to the index procedure and prior to randomization to confirm anatomic compatibility with the study device and the control device. Subjects must meet the following anatomical inclusion criteria:
- EmStop Angiographic (CTA) Inclusion Criteria 1. Subject anatomy is compatible with correct device positioning with:
- Ascending aorta length ≥8 cm
- Femoral and iliac artery minimal lumen diameter of ≥ 8.0 mm
- Ascending aorta/aortic arch diameter is ≥25 or ≤40 mm.
- Ascending aorta or aortic arch exhibits ≤ Grade 1 atheromatous disease and limited wall calcification
- Sentinel Angiographic (CTA) Inclusion Criteria
- Subject anatomy, excluding bovine arch anatomy, is compatible with correct device positioning with:
- Artery diameter is 9-15 mm for the brachiocephalic artery and 6.5-10 mm in the left common carotid artery
- Arterial stenosis <70% in either the left common carotid artery or the brachiocephalic artery
- Brachiocephalic or left carotid artery without significant stenosis, ectasia, dissection, or aneurysm at the aortic ostium or within 3 cm of the aortic ostium
- Adequate blood flow to the right upper extremity
- Access vessels without excessive tortuosity
