Biomechanical Evaluation of Ascending Aortic Aneurysms
The biomechanical properties of ascending aortic aneurysms were investigated only in the last decade in a limited number of studies. Indeed, in recent years, there has been a growing interest in this field in order to identify new predictive parameters of risk of dissection, which may have clinical relevance. The researches performed so far have been conducted according to the methods used in t...
متن کاملBiomechanical evaluation of the walls of abdominal aortic aneurysms
The development of an abdominal aortic aneurysm (AAA) is a long-lasting, gradual and, usually, asymptomatic process. Thus, the diagnostics of the aneurysm poses some difficulties and most cases are diagnosed by accident. An untreated aneurysm results in death when its walls are destroyed. The mortality rate in the case of the abdominal aortic aneurysms’ rupture ranges from 80% to 90% [1, 2]. A ...
متن کاملAscending Aneurysms in Bicuspid Aortic Valve
The bicuspid aortic valve (BAV), the most common congenital cardiac malformation, is associated with ascending thoracic aneurysms and appears to reflect a common developmental defect. (Hahn et al., 1992; Roberts, 1970) The average time of patients with BAV undergoing surgery (of the aortic valve and/or because of complications associated with it) is a decade earlier than patients with a normall...
متن کاملProximal aortic arch cannulation for proximal ascending aortic aneurysms
INTRODUCTION Different arterial inflow sites have been reported to date for particularly challenging cardiac operations. The ascending aorta, femoral artery, and subclavian artery are the most commonly used sites. Although its use has been reported, the aortic arch has not gained popularity in the performance of cannulation. According to a search performed in the PubMed database, aortic arch ca...
متن کاملBiaxial rupture properties of ascending thoracic aortic aneurysms.
UNLABELLED Although hundreds of samples obtained from ascending thoracic aortic aneurysms (ATAA) of patients undergoing elective surgical repair have already been characterized biomechanically, their rupture properties were always derived from uniaxial tensile tests. Due to their bulge shape, ATAAs are stretched biaxially in vivo. In order to understand the biaxial rupture of ATAAs, our group d...
