Atherosclerosis and aneurysm of the aorta are relatively common pathological conditions that remain asymptomatic for a long period of time and have life-threatening and disabling complications. DNA methylation profiling in several regions (a dilated area, a nondilated area, and an atherosclerotic plaque) of the ascending aorta was carried out in patients with aortic aneurysm. DNA methylation was analyzed by reduced representation bisulfite sequencing (RRBS).

Department of Pharmacology, Xiangya School of Pharmaceutical Sciences, Central South University, Changsha 410078, Hunan, China; Hunan Provincial Key Laboratory of Cardiovascular Research, Central South University, Changsha 410078, Hunan, China. Electronic address:

Aortic aneurysm and dissection pose fatal threats but no effective drug therapies are available. Previous work has been directed to reduce risk factors or target key pathological events, but none of the translational efforts succeeds. Here, we attempt to repurpose dimethyl fumarate (DMF), an FDA-approved immunomodulatory drug for multiple sclerosis, for the treatment of aortic aneurysm and dissection.

Background: The aim of this study is to explore the value of different systemic inflammatory response indicators in the long-term prognosis of type B aortic dissection (TBAD) patients undergoing thoracic endovascular aortic repair (TEVAR).

Methods: This study retrospectively reviewed the case data of 540 patients with TBAD at our center from January 2013 to January 2019. Based on the occurrence of aorta-related adverse events (ARAEs) during follow-up, patients were divided into two groups: the ARAEs group and the non-ARAEs group.

December 2024

Department of Structural Heart Disease, National Center for Cardiovascular Disease, China & Fuwai Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College, Beijing, China.

Background: Abnormal blood flow patterns are known to contribute to the ascending aortic dilation in patients with bicuspid aortic valve (BAV). The present study elucidated the blood flow characteristics in the dilated ascending aorta before and after transcatheter aortic valve replacement (TAVR) using computational fluid dynamics (CFD) analysis.

Methods: We performed CFD analysis in three BAV patients with ascending aortic dilation (maximum diameter ≥ 45 mm) who underwent TAVR.

Effect of Statins on the Prognosis After Thoracic Endovascular Aortic Repair for Patients With Acute Type B Aortic Dissection.

J Endovasc Ther

December 2024

National Key Laboratory of Frigid Zone Cardiovascular Disease, Cardiovascular Research Institute and Department of Cardiology, General Hospital of Northern Theater Command, Shenyang, China.

Objective: To analyze the clinical efficacy of long-term statin therapy following thoracic endovascular aortic repair (TEVAR) in patients with acute type B aortic dissection (ATBAD).

Methods: We retrospectively analyzed data from 645 patients treated between January 2005 and June 2022, dividing them into Statin Group (n=330) and Non-statin Group (n=315) based on whether they received long-term postoperative statin therapy. Patients were further categorized based on median admission low-density lipoprotein cholesterol (LDL-C) levels into High and Low LDL-C Groups to assess the effect of statins on the prognosis of ATBAD patients after TEVAR.

Iatrogenic type A aortic dissection (IAAD) is a rare but life-threatening complication of percutaneous coronary intervention (PCI), often presenting significant therapeutic challenges. A looped guidewire between the right subclavian artery and brachiocephalic artery during coronary angiography (CAG) via right radial artery access can complicate catheter manipulation. This report discusses the case of a 58-year-old hypertensive female patient who developed aortic dissection during PCI, specifically due to wire manipulation at the brachiocephalic loop.

Contrast-enhanced CT is a primary tool in emergency departments for diagnosing acute aortic dissection, demonstrating high sensitivity and specificity. However, artifacts such as streak artifacts can mimic aortic dissection, leading to misdiagnosis. Here, we report a case involving a 21-year-old male who sustained traumatic injuries after a motor vehicle accident.

Acute aortic dissection is considered a contraindication to the use of intravenous thrombolysis in patients presenting with acute ischaemic stroke, but less has been described about previously repaired dissections. We present a case of a woman in her 50s presenting with acute left hemiparesis with a known history of aortic dissection within the thrombolysis window. After multidisciplinary discussion with cardiothoracic surgery and discussion with the patient, she was treated with intravenous thrombolysis without complication.

Research progress on the role of ferroptosis in aortic dissection.

Zhejiang Da Xue Xue Bao Yi Xue Ban

December 2024

Department of Vascular Surgery, Zhongshan Hospital, Fudan University (Xiamen Branch), Xiamen 361015, Fujian Province, China.

Recent studies have shown that iron metabolism dysregulation and lipid peroxidation-induced ferroptosis, triggered by oxidative stress, play a key role in the development of aortic dissection. Dysregulated iron metabolism leads to excessive production of hydroxyl radicals due to abnormal iron levels and heme metabolism, while lipid peroxidation is linked to Xc system dysfunction and accumulation of phospholipid hydroperoxides. These factors synergistically disrupt aortic homeostasis and drive ferroptosis of vascular cells, including endothelial and smooth muscle cells.
