Embol-X Embolic Protection Device

CardioGard Cannula

Standard Cannula

Arm Description

The surgeon may use either the EMBOL-X® Access Device/Aortic Cannula or a standard cannula with the EMBOL-X® filter deployed through a separate introducer sheath.

The Cardiogard embolic protection device is a curved tip 24-French aortic perfusion cannula.

Outcomes

Primary Outcome Measures

Percentage of Participants With Freedom From Clinical or Radiographic Central Nervous System (CNS) Infarction
freedom from CNS infarction, defined as brain, spinal cord, or retinal cell death attributable to ischemia based on neuropathological, neuroimaging, or clinical evidence of permanent injury based on symptoms persisting > 24 hours, with overt symptoms or no known symptoms. All patients will be assessed by 1.5 T (3.0 T is acceptable if 1.5 T not available) Diffusion-weighted imaging (DWI) at 7 (± 3) days post procedure for presence of brain lesions and to measure the number and volume of any present lesions.

Quality of Life - Physical Health Composite
Quality of Life - Physical Health Composite Assessed by Short Form-12 (SF-12). Score ranking from 0 (worst health) to 100 (best health) calculated as the weighted sum of the questions. health scores then transformed into a t-score on the assumption that each question carries equal weight and were standardized to have mean of 50 and standard deviation of 10.
Quality of Life - Mental Health Composite
Quality of life - Mental health composite Assessed by Short Form-12 (SF-12). Score ranking from 0 (worst health) to 100 (best health) calculated as the weighted sum of the questions. health scores then transformed into a t-score on the assumption that each question carries equal weight and were standardized to have mean of 50 and standard deviation of 10.
