Background And Aim Of The Study: To reveal a technical feasibility and safety of valve-sparing partial aortic root repair for spontaneous aortic dissection limited to the right coronary sinus of Valsalva.
Methods: A 68-year-old woman presented with chest pain. Twelve-lead electrocardiogram revealed atrioventricular dissociation and ST-segment elevation on II, III, and aVF. Enhanced computed tomography images showed aortic dissection limited to the right-coronary sinus and the other non-dilated sinuses of Valsalva. Localized aortic dissection was repaired by valve-sparing partial aortic root repair using a trimmed U-shaped Dacron graft and a felt strip, and the right coronary artery was revascularized by coronary artery bypass grafting using saphenous vein graft.
Results: The patient was discharged on postoperative day 12 with no complications.
Conclusion: Valve-sparing partial aortic root repair with the patch and coronary artery bypass grafting for aortic dissection limited to the right coronary sinus of Valsalva were technically feasible and safe.

Aortic dissection (AD) is one of the most dangerous diseases of the cardiovascular system, which is characterized by acute onset and poor prognosis, while the pathogenesis of AD is still unclear and may affect or even delay the diagnosis of AD. Anchorage-dependent cell death (Anoikis) is a special mode of cell death, which is programmed cell death caused by normal cells after detachment from extracellular matrix (ECM) and has been widely studied in the field of oncology in recent years. In this study, we applied bioinformatics analysis, according to the results of research analysis and Gene Ontology (GO), as well as Kyoto Encyclopedia of Genes and Genomes (KEGG), finally found 3 anoikis-related genes (ARGs) based on machine learning.

Background: Sporadic aortic aneurysm and dissection (AAD) is a critical condition characterised by the progressive loss of vascular smooth muscle cells (VSMCs) and the breakdown of the extracellular matrix. However, the molecular mechanisms responsible for the phenotypic switch and loss of VSMCs in AAD are not fully understood.
Methods And Results: In this study, we employed a discovery-driven, unbiased approach.

Aortitis, defined as inflammation of the aorta, can lead to aneurysms and dissections. Intra-operative sampling is essential for diagnosis, with many cases presenting asymptomatically as clinically isolated aortitis. Previous studies investigating aortitis in major aortic surgery have been limited by low intra-operative sampling.

Introduction: Balancing the well-documented benefits of regular exercise, particularly its positive impact on cardiovascular risk factors like hypertension, with the potential risks for patients with aortic aneurysms presents a significant challenge. This narrative review aims to summarize the current evidence and guidelines to assist clinicians in making informed exercise and sports recommendations for patients with aortic aneurysms or post-aortic repair.
Methods: Nine clinical trials on the effect of exercise on abdominal aortic aneurysms (AAAs) were identified, including one study on cardiopulmonary exercise testing (CPET) in AAA patients.
