The Functional Limits of the Aneurysmal Aortic Root: A Unique Pressure Testing Apparatus

Abstract

The aortic root has unique embryological development and is a highly sophisticated and complex structure. In studies that report on the biomechanical characteristics of the thoracic aorta, distinction between the aortic root and ascending aorta regions is non-existent. This study aimed to determine the maximal pressures at which dissection or tissue failure occur in both the aneurysmal aortic root and ascending aorta and to analyse any differences. This may help guide preoperative monitoring, diagnosis, and the decision for operative intervention for aortic root aneurysms in normal and susceptible populations.
