Of 57 who underwent TARFET using FROZENIX, 9 were excluded (3 scheduled secondary thoracic endovascular aortic repair; 6 lost to CT follow-up), leaving 48 patients. The following CT parameters were measured at discharge and at 6 months, 1 year, and 2 years: distal landing zone level, stent migration, landing zone angle, and stent-to-aorta diameter ratio. Patients were classified as the shrinkage group (&amp;gt;10% diameter decrease) or the no-change group (\u226410% change or expansion).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Mean age was 75.6 years and mean aneurysm diameter was 58.1\u2009mm. In-hospital mortality was 0%; stroke and spinal cord injury (paraparesis) each occurred in 2 patients (4.2%). Type Ib endoleak occurred in 1 patient (2.1%). Aneurysm shrinkage was achieved in 31 patients (64.6%). The initial landing zone angle was clinically and statistically smaller in the shrinkage group than in the no-change group (15.1 \u00b1 11.5\u00b0 vs 26.8 \u00b1 21.1\u00b0, a difference of approximately 12\u00b0; P\u2009=\u20090.046). No significant differences were observed in angle change (P = 0.63), landing length (P = 0.95), diameter ratio (P = 0.91), or migration (P = 0.44).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>In this exploratory subgroup analysis, a larger initial stent graft landing zone angle was associated with failure of aneurysm shrinkage after TARFET for true degenerative distal arch aneurysms.
