The AAA models used included periadventitial infrarenal aortic calcium chloride application in five studies, intraluminal infrarenal aortic elastase in three studies (including the addition of aortic balloon dilatation and juxta-renal stenosing cuffs in the pig study) [25], periadventitial infrarenal aortic elastase application in two studies and subcutaneous angiotensin II infusion in one study (Table 1). This evidence concerns the gene AGT and triple-A syndrome.
