Objective: This study aimed to evaluate the serum gamma-glutamyltransferase (GGT) levels as an indirect marker of elevated oxidative stress in patients with dilated ascending aorta.
Methods: The study was designed as an observational cross-sectional controlled study. One hundred consecutive patients with dilated ascending aorta and 50 consecutive controls with normal ascending aorta diameter were selected for the study by comprehensive transthoracic echocardiography (TTE). The aortic dilatation group was divided into two subgroups, according to the literature as the ectasia group (3.8-4.3 cm, 53 patients, 24 male and 29 female, mean age: 62.9±10.9 years) and the aneurysm group (≥4.4 cm, 47 patients, 18 male and 29 female, mean age: 65.5±11.1 years). The control group consisted of patients demonstrating no ascending aorta dilatation (≤3.7 cm, 50 patients, 24 male and 26 female, mean age: 62.7±9.2 years). ANOVA, Mann-Whitney U test, Pearson's correlation analysis, multivariate logistic regression analysis, and receiver-operator curve analysis were used for statistical analysis.
Results: Regarding the comparison of laboratory parameters between the patient and control groups, serum gamma-glutamyltransferase (GGT) levels were found to be statistically significantly higher in both of the aortic dilatation subgroups than in the control group (p<0.001). In the correlation analysis between the ascending aorta diameter and GGT, a statistically significant positive correlation was found (r=0.282, p<0.001). The multivariate regression analysis revealed a significant relationship between GGT and the proximal ascending aorta diameter (β=0.131, odds ratio: 1.140, 95% CI: 1.060-1.225, p<0.001).
Conclusion: GGT as a marker of oxidative stress may play a role in the pathogenesis of aneurysm of the ascending aorta.

Adverse aortic remodeling increases the risk of aorta-related adverse events (AAEs) after thoracic endovascular aortic repair (TEVAR) and affects the overall prognosis of aortic dissection (AD). It is imperative to delve into the exploration of prognostic indicators to streamline the identification of individuals at elevated risk for postoperative AAEs, and therapeutic targets to optimize the efficacy of TEVAR for patients with AD. Here, we perform proteomic and single-cell transcriptomic analyses of peripheral blood and aortic lesions, respectively, from patients with AD and healthy subjects.

Background: We investigated the effects of C-reactive protein (CRP) deposition on the vessel walls in abdominal aortic aneurysm (AAA) by analyzing spatially resolved changes in gene expression. Our aim was to elucidate the pathways that contribute to disease progression.
Methods: AAA specimens from surgically resected formalin-fixed paraffin-embedded tissues were categorized into the AAA-high CRP [serum CRP ≥ 0.

Objective: Berry syndrome is a group of rare congenital cardiac malformations including aortopulmonary window (APW), aortic origin of the right pulmonary artery (AORPA), interruption of the aortic arch (IAA), patent ductus arteriosus (PDA) (supplying the descending aorta) and intact ventricular septum. This paper will analyze the clinical data of 7 patients with Berry syndrome who underwent surgical treatment in our institution and discuss the one-stage surgical correction of Berry syndrome in combination with the literature.
Methods: From January 2013 to July 2024, a total of 7 children with Berry syndrome were admitted to the Cardiac Surgery Department of Beijing Children's Hospital.

The patient an 85-year-old female resided in a care facility where she maintained an independent daily activity level. She was discovered hunched over a table in her room, displaying reduced responsiveness and prompting an emergency call. Initially, her blood pressure was within 60 mmHg, and she was transported by ambulance to our hospital.
