Many models, including nongenetic and genetic models, were compared using likelihood methods. 2 The pathogenesis of AAA remains poorly understood, however significant evidence has emerged in recent years to suggest a chronic inflammatory process. The primary cardiovascular abnormality is an aneurysm of the aortic root, which often extends into the proximal portion of the tubular ascending thoracic aorta to create a pear-shaped aortic dilatation that is sometimes referred to as annuloaortic ectasia.
