The standard treatment for ruptured type A aortic dissection is open surgical repair. We have described the case of a frail patient with home oxygen-dependent chronic obstructive pulmonary disease and prior free vein circumflex coronary artery bypass who had presented with a ruptured type A aortic dissection and was deemed too high risk for open surgery. On July 7, 2017, the patient underwent emergent endovascular ruptured ascending thoracic aortic aneurysm repair with a chimney stent graft to a free vein coronary bypass that originated from the ascending thoracic aorta. The procedure was uneventful, and the patient was discharged home on postoperative day 1.

Predicting the evolution of ascending aortic aneurysm (AscAA) growth is a challenge, complicated by the intricate interplay of aortic geometry, tissue behavior, and blood flow dynamics. We investigate a flow-structural growth and remodeling (FSG) model based on the homogenized constrained mixture theory to simulate realistic AscAA growth evolution. Our approach involves initiating a finite element model with an initial elastin insult, driven by the distribution of Time-Averaged Wall Shear Stress (TAWSS) derived from computational fluid dynamics simulations.

Background: Adults with spinal deformity (ASD) are known to have spinal malalignment, which can impact their quality of life and their autonomy in daily life activities. Among these tasks, ascending and descending stairs is a common activity of daily life that might be affected.
Research Question: What are the main kinematic alterations in ASD during stair ascent and descent?
Methods: 112 primary ASD patients and 34 controls filled HRQoL questionnaires and underwent biplanar X-from which spino-pelvic radiographic parameters were calculated.

Background: Individuals harbouring pathogenic variants are at risk for aneurysms/dissections throughout the arterial tree. Based on prior reports of sex differences in thoracic aortic aneurysm/dissection, we investigated the sexual dimorphism for vascular events in variant-harbouring patients.
Methods: We analysed two large pedigrees comprising 84 individuals segregating pathogenic missense variants affecting the same p.

Background: Takayasu arteritis is a large-vessel vasculitis, in addition to giant cell arteritis. Various post-operative complications associated with the cardiac macrovasculature have been reported. Detachment of the prosthetic valve, pseudoaneurysm formation, and dilatation of the aortic root are well-known post-operative complications associated with vasculitis syndromes, including Takayasu arteritis.
