Effect of the Proximal Landing Zone Quality on TEVAR Outcomes—11-Year Real-World Experience with the Relay Stent Graft Family in Aortic Dissections

Proximal TEVAR landing in healthy aorta was associated with fewer peripheral ischemic complications, a lesser risk for stent graft movement >1.5 mm, a tendency for better aortic remodeling, and less proximal aneurysm formation during FU, even if survival differences were not significant. CAD was a major risk factor for long-term mortality and should therefore be taken into account preoperatively whenever possible.Clinical ImpactThe study results support proximal TEVAR landing in healthy aorta when treating aortic dissections(AD), showing fewer peripheral ischemic complications, a lesser risk for stent graft movement >1.5mm, a tendency for better aortic remodeling and less proximal aneurysm formation during long-term follow-up. The statistically non-significant trend for inferior long-term survival in patients with TEVAR landing in healthy aorta merits further investigation in contemporary cohorts. Finally, the results show that coronary artery disease is a major risk factor for long-term mortality after TEVAR for AD, highlighting the relevance of close monitoring and, whenever possible, preoperative cardiological patient work-up.
