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].
