Should we do Ascending Plus Hemiarch OR Prophylactic ET ? Managing Moderately Dilated Descending 69y/o Female, vague chest pain w/o CAD Ascending aorta 6.1cm and Descending aorta 4.6cm Should we do Ascending Plus Hemiarch OR Prophylactic ET ?
Objectives Characterize patients Assess risk vs benefit of prophylactic ET

Prophylactic 1st Stage ET Effective strategy for staged repair of moderately dilated descending aorta Should be considered in high risk pts with chronic dissection, connective tissue disorder, aortitis, etc. Offers long term benefit for treatment of late distal aortic disease progression and acute complications with EEC or OEC
