Current clinical intervention criteria for ascending thoracic aneurysms (ATAAs) are based on the maximum diameter value, however rupture may occur even at smaller dilatation levels. Moreover, the presence of the bicuspid aortic valve complication (BAV) increases the rupture risk. The aim of this study is to investigate and identify additional potential morphological features and to correlate them with histomechanical findings, with particular attention on the BAV complication compared with the TAV cases
