Elective frozen elephant trunk procedure using the E‐Vita Open Plus prosthesis in 94 patients: a multicentre French registry

OBJECTIVES Our goal was to evaluate the operative outcomes of the frozen elephant trunk technique using the E‐Vita Open Plus® hybrid prosthesis in chronic aortic arch diseases and report clinical and radiological outcomes at the 1‐year follow‐up. METHODS As determined from a prospective multicentre registry, 94 patients underwent frozen elephant trunk procedures using the E‐Vita Open Plus hybrid device for the treatment of chronic aortic conditions, including 50% chronic aortic dissections, 40% degenerative aneurysms and 10% miscellaneous indications. Fifty percent of the cases were reoperations. RESULTS The perioperative mortality rate was 11.7%. Spinal cord ischaemia and stroke rates were 4% and 9.6%, respectively. The mean cardiopulmonary bypass time was 252 ± 97 min, cardiac ischaemia time was 152 ± 53 min and cerebral perfusion time was 82 ± 22 min. Concomitant procedures were observed in 15% of patients. Among the 83 surviving patients, the survival rate after the 1‐year follow‐up was 98%. Eleven percent of patients underwent endovascular completion, whereas 4% of patients required aortic reintervention at 1 year. CONCLUSIONS The E‐Vita Open Plus hybrid device confirms the favourable short‐ and mid‐term outcomes offered by its predecessor in frozen elephant trunk procedures in patients with chronic aortic arch disease. Implantation of the E‐Vita Open Plus is associated with good 1‐year survival rates, good rates of favourable aortic remodelling in both chronic dissection and degenerative aneurysms and a reproducible technique in a multicentre registry. Continued follow‐up is required due to the risk of evolution at the downstream aorta.
