predominant aortic regurgitation >3+)

- A known contraindication or hypersensitivity to all anticoagulation regimens or
an inability to undergo anticoagulation for the study procedure

therapy is contraindicated, patients who will refuse transfusion, or havean
active peptic ulcer or upper GI bleeding within the prior 3 months

- Renal insufficiency, defined as a creatinine level > 221µmol/L and/or end-stage
renal disease requiring chronic dialysis at time of treatment

- Life expectancy < 12 months due to non-cardiac co-morbid conditions

- Evidence of active systemic or local groin infection

- Significant aortic disease, including abdominal aortic or thoracic aneurysm
defined as maximal luminal diameter 5cm or greater; marked tortuosity (hyperacute
bend), aortic arch atheroma or narrowing (especially with calcification and
surface irregularities) of the abdominal or thoracic aorta, severe "unfolding"
and tortuosity of the thoracic aorta
