4/4/2014 Why is Stroke a marker for poor Late Outcomes after Carotid survival? Intervention • Peri-procedural MI is bad and Stoke is worse • Minor Stroke and even TIA substantially reduce long term survival • Unknown role for silent ischemia (DW-MRI) • A new era where we recognize that peri- procedural outcomes are only part of the cost of intervention. Brain uniquely susceptible to emboli 4
