A detailed , open and stimulating discussion of a presentation in the AATS . The presenter responds to peer questioning on the technical aspects of the evolution of hubrid interventions collated under the mantle of B-SAFER (Branched stented anastomosis frozen elephant trunk repair.
The unredacted discussion is available on https://www.aats.org/resources/branched-stented-anastomosis-frozen-eleph…
Important points raised : no oversizing, semantics in temperature control( differences between nasopharyngeal and urinary bladder readings)  , and of course, the concept of achieving a complete seal between surgical graft, stent and aortic wall.
