Apposition of the stent-graft to the outer aortic wall of the newly created common aortic lumen with elimination of retrograde false lumen flow was achieved in all cases. This is the first description using the laser technology to optimize the distal landing zone for cTBAD. This new technique is safe and reproducible, with excellent controllability to achieve aortic septotomy at the desired target aorta segment.

Racial minority and female trainees undergo residency attrition at significantly higher rates than their counterparts. We hypothesize that racial minority, and female trainees will report significantly different training experiences from non-minority and male trainees, respectively. Further, we hypothesize that thoughts of withdrawal and summative description of residency experience will be significantly impacted by access to mentorship and feelings of isolation. A link to a Qualtrics survey was sent to program officials from all residency programs registered with the ACGME to be distributed to their trainees. It was live from June through August of 2019 and collected data about respondent's demographics and posed questions addressing some of the key elements of the residency experience. Minority trainees reported lower scores for ease of execution of orders placed compared to non-minority trainees 2.12 vs. 2.28 (p=0.030). Females reported more frequently being mistaken for staff at lower training levelse trainees. Thoughts of withdrawal and overall residency experience are significantly impacted by acces
