Brief summary

The objective of this study is to compare the safety and effectiveness of the F2 Cerebral Protection System (CPS) to a standard of care control group in patients undergoing Transcatheter Aortic Valve Replacement (TF TAVR)

Detailed description

The study is designed to demonstrate that the F2 Cerebral Protection System (CPS) performs in a consistent manner as the control group in terms of safety, and the F2 Cerebral Protection System (CPS) will be superior in performance when compared to the control group in terms of effectiveness in patients undergoing Transcatheter Aortic Valve Replacement (TF TAVR).

Interventions

Use of the F2 Filter and Delivery System in conjunction with a Transcatheter Aortic Valve Replacement (TAVR) procedure

PROCEDURETranscatheter Aortic Valve Replacement (TAVR)

Transcatheter Aortic Valve Replacement (TAVR) with commercially available Transcatheter Aortic Valve Replacement (TAVR) device

Primary

MeasureTime frameDescription
Major Adverse Cardiac and Cerebrovascular Events (MACCE)30 days post procedureMACCE includes the composite of death, all stroke, acute kidney injury (AKI) stage 3 or 4 within 7 days post-index procedure Valve Academic Research Consortium 3 (VARC-3) and any major vascular complication (VARC-3)
Total New Lesion Volume8-72 hours post procedureTotal new lesion volume (TNLV) in the brain assessed by diffusion weighted magnetic resonance images (DW-MRI)

Secondary

MeasureTime frameDescription
Stroke30 days post procedureIncidence of all stroke events

Other

MeasureTime frameDescription
Average Lesion Size8-72 hours post procedureMeasure average lesion size in the brain, assessed by diffusion weighted magnetic resonance images (DW-MRI)
Neurological Outcomes-National Institute of Health Stroke Scale (NIHSS)30 days post procedureUse National Institute of Health Stroke Scale (NIHSS) to measure stroke severity on a scale of 0-41 (low score is better outcome).
Neurological Outcomes-Montreal Cognitive Assessment (MoCA)30 days post procedureUse Montreal Cognitive Assessment (MoCA) to measure cognitive impairment on a scale of 0-30 (high score is better outcome).
Neurological Outcomes-Modified Rankin Scale (MRS)30 days post procedureUse Modified Rankin Scale (MRS) to measure neurological disability on scale of 0-6 (Low score is better outcome)
Major Vascular Complication & BleedingDuring procedureMeasure major vascular complications (as defined by VARC-3) & major bleeding (Type 3, Type 4 as defined by VARC- 3)
PerformanceDuring procedureTechnical success (% of patients with successful device deployment, position and retrieval) and procedure success (% of patients with technical device success and no device-related safety events)
Index Hospital Length of Stay (LOS)Through 30 daysMeasure Index hospitalization LOS
Index Hospitalization ICU Length of Stay (LOS)Through 30 daysMeasure Index hospitalization ICU length of stay
Kansas City Cardiomyopathy Questionnaire (KCCQ)30 days post procedureThe Kansas City Cardiomyopathy Questionnaire (KCCQ) is a self-reported questionnaire that measures physical function, symptoms, social function, and quality of life, on a scale from 0 to 100 (higher score is better outcome).
Short Form (SF-12) Questionnaire30 days post procedureThe Short Form (SF-12) Questionnaire is a self-reported questionnaire that assess the impact of health on an individual's everyday life, on a scale from 0 to 100 (higher score is better health).
Hospital Readmissions30 days post procedureMeasure number of hospital readmissions at 30 days and number of ICU readmissions during hospital stay and 30 days
Mortality & Stroke Rates30 days post procedureIncidences of all-cause mortality, major stroke, minor stroke events
Freedom from Lesions8-72 hours post procedureMeasure presence or absence of new lesions in the brain, assessed by diffusion weighted magnetic resonance images (DW-MRI)
