Early outcomes of the Frozenix J-graft with exclusion of the non-stent part at a single center.

J Thorac Dis 2022 Apr;14(4):1031-1041

Department of Cardiovascular Surgery, Osaka City University Graduate School of Medicine, Osaka, Japan.

Background: The frozen elephant trunk technique is useful in aortic arch repair; however, some adverse events are associated with the Frozenix J-graft. We designed a technique to prevent these adverse events and achieve easy anastomosis (Total Exclusion of the Non-Stent part of Frozenix using an Everting anastomosis [TENSE]), and we assessed the outcomes of this technique in the present study.

Methods: From April 2017 to May 2021, 44 patients with aortic arch disease underwent TENSE, in which the proximal stump of the stent part of Frozenix was matched to the distal anastomosis end between the left common carotid and left subclavian arteries. Read More

Regional and directional variations in the layer-specific resistance to tear propagation in ascending thoracic aortic aneurysms.

J Biomech 2022 May 10;138:111133. Epub 2022 May 10.

Laboratory of Biomechanics, Center of Clinical, Experimental Surgery, and Translational Research, Biomedical Research Foundation of the Academy of Athens, Athens, Greece. Electronic address:

Aortic dissection often initiates a few centimeters distal to the coronary ostia in the right lateral wall, with an intimal-medial tear that tends to be transversely directed and occupy half of the aortic circumference, sometimes less, but seldom the entire circumference. To elucidate these clinical observations, tear tests were presently used to determine the layer-specific resistance to tear propagation in ascending thoracic aortic aneurysms, assessing variations over the four circumferential quadrants and two directions. Aneurysmal tissue strips of standardized dimensions from sixteen patients were anatomically separated into layers (seven hundred and twelve) and an incision made along one-third of their length.

Research progress on the pathogenesis of aortic dissection.

Curr Probl Cardiol 2022 May 11:101249. Epub 2022 May 11.

Department of Cardiovascular Surgery, Shenzhen People's Hospital (The Second Clinical Medical College, Jinan University); The First Affiliated Hospital, Southern University of Science and Technology, Shenzhen, 518020, Guangdong, China. Electronic address:

Aortic dissection (AD) is a critical cardiovascular disease due to the separation of media and adventitia caused by the rupture of vascular wall intima. The disease has a high mortality rate of about 1% to 3% for each additional hour, since the adventitia of the aorta can rupture and bleed to death at any time. Although great progress has been made in clinical treatment of aortic dissection, and the mortality rate has been significantly reduced, the pathogenesis is still not very clear. Read More

Int J Environ Res Public Health 2022 May 6;19(9). Epub 2022 May 6.

School of Automation, Central South University, Changsha 410083, China.

Aortic dissection (AD) is a rare and high-risk cardiovascular disease with high mortality. Due to its complex and changeable clinical manifestations, it is easily missed or misdiagnosed. In this paper, we proposed an ensemble learning model based on clustering: Cluster Random under-sampling Smote-Tomek Bagging (CRST-Bagging) to help clinicians screen for AD patients in the early phase to save their lives.

The Predictive Role of Plasma Biomarkers in the Evolution of Aortopathies Associated with Congenital Heart Malformations.

Int J Mol Sci 2022 Apr 30;23(9). Epub 2022 Apr 30.

Department of Pediatrics III, Faculty of Medicine in English, George Emil Palade University of Medicine, Pharmacy, Science, and Technology of Targu Mures, 540136 Târgu Mureș, Romania.

Dilatation of the aorta is a constantly evolving condition that can lead to the ultimate life-threatening event, acute aortic dissection. Recent research has tried to identify quantifiable biomarkers, with both diagnostic and prognostic roles in different aortopathies. Most studies have focused on the bicuspid aortic valve, the most frequent congenital heart disease (CHD), and majorly evolved around matrix metalloproteinases (MMPs). Read More

The Role of Telocytes and Telocyte-Derived Exosomes in the Development of Thoracic Aortic Aneurysm.

Int J Mol Sci 2022 Apr 25;23(9). Epub 2022 Apr 25.

Department of General Surgery, Medical University of Vienna, 1090 Vienna, Austria.

A hallmark of thoracic aortic aneurysms (TAA) is the degenerative remodeling of aortic wall, which leads to progressive aortic dilatation and resulting in an increased risk for aortic dissection or rupture. Telocytes (TCs), a distinct type of interstitial cells described in many tissues and organs, were recently observed in the aortic wall, and studies showed the potential regulation of smooth muscle cell (SMC) homeostasis by TC-released shed vesicles. The purpose of the present work was to study the functions of TCs in medial degeneration of TAA. Read More

Usefulness of 18F-FDG PET/computed tomography in differentiating between subacute and chronic aortic dissection: initial investigation.

Nucl Med Commun 2022 May 13. Epub 2022 May 13.

Department of Radiology, Mie University Hospital, Edobashi, Tsu.

Objectives: In the selection of thoracic endovascular repair for aortic dissection (AD), it is important to distinguish between the subacute and chronic phases, but there is no reliable way to distinguish between them in patients with unknown onset of AD. The purpose of this study was to assess the diagnostic performance of 2-[18F] fluoro-2-deoxy-d-glucose (18F-FDG)-PET/computed tomography (PET/CT) for discriminating subacute AD from chronic AD.
