Introduction
The frozen elephant trunk (FET) facilitates access to the ascending
aorta, aortic arch, and the descending thoracic aorta via a median
sternotomy, helping to address a wide range of aortic pathology. With
increasing in popularity, over 30,000 hybrid prosthesis has been
implanted across the globe [1]. The understanding of aortic
pathology and the pathophysiological mechanisms coupled with the
advancements in the techniques and technology has produced excellent
long term results of survival probability of 5 years for acute Type A
aortic dissection, chronic aortic dissection and thoracic aortic
aneurysm at 91%, 98% and 92% respectively [2].
