Objectives:
Total arch replacement using the frozen elephant trunk technique remains the gold standard for a definite aortic arch repair. To facilitate surgical management of the left subclavian artery (LSA), a new hybrid frozen elephant trunk device was recently developed.
Methods:
A 62-year-old female patient presented with acute type A aortic dissection and underwent emergent aortic root and total arch replacement using the novel custom-made Evita Neo EDE hybrid arch device for frozen elephant trunk implantation. To facilitate the management of the LSA, a covered stent connected to the device was inserted into the LSA via guidewire prior to performing the distal anastomosis in zone two.
Results:
Postoperative computed tomographic angiography demonstrated excellent outcome and technical success with no signs of endoleak or device-related complications. The patient was discharged home 11 days after surgery in a stable clinical condition.
Conclusions:
The new Neo EDE hybrid arch device for frozen elephant trunk implantation is easy to use and simplifies surgical management of the LSA without adding technical complexity.
