The thoracic diaphragm, or simply the diaphragm (Ancient Greek: , romanized: diphragma, lit. Electronic health records, death certificates as well as post-mortem analyses (such as post-mortem computed tomography and Atrial fibrillation (AF or A-fib) is an abnormal heart rhythm (arrhythmia) characterized by rapid and irregular beating of the atrial chambers of the heart. Aortic intramural hematoma is an atypical form of aortic dissection due to a contained hemorrhage into the aortic wall usually from the vasa vasorum without an intimal tear. It forms part of the acute aortic syndrome spectrum along with penetrating atherosclerotic ulcer and classical aortic dissection. Aortic dissection is defined as a tear in the innermost layer of the aortic wall (ie, intima), which results in high-pressure blood flow between the layers of t Peterss S, Mansour AM, Ross JA, et al. Underlying causes. Circulation. A systematic review and meta-analysis of stroke rates in patients undergoing thoracic endovascular aortic repair for descending thoracic aortic aneurysm and type B dissection Georgios I. Karaolanis Constantine N. Antonopoulos In the spring of 2020, we, the members of the editorial board of the American Journal of Surgery, committed to using our collective voices to publicly address and call for action against racism and social injustices in our society. The Journal of the American Society of Echocardiography(JASE) brings physicians and sonographers peer-reviewed original investigations and state-of-the-art review articles that cover conventional clinical applications of cardiovascular ultrasound, as well as newer techniques with emerging clinical applications.These include three-dimensional echocardiography, strain and neurologic injury after surgical repair with hypothermic circulatory arrest in acute and chronic proximal thoracic aortic pathology: effect of age on outcome. A tear in the intimal layer results in the progression of the dissection (either proximal or retrograde) chiefly due to the entry of blood in between the intima and media. The size cut off for aortic aneurysm is crucial to its treatment. Changing Pathology of the Thoracic Aorta From Acute to Chronic Dissection: Literature Review and Insights. Aortic dissection is due to the separation of the layers of the aortic wall. infectious. New Journal Launched! J Am Coll Cardiol 2016; 68:1054. Aortitis refers to a general descriptor that involves a broad category of infectious and non-infectious conditions where there is inflammation (i.e. It typically gets worse over time. 441 Aortic aneurysm and dissection. Changing Pathology of the Thoracic Aorta From Acute to Chronic Dissection: Literature Review and Insights. Annals of Vascular Surgery: Brief Reports and Innovations is a gold open access journal launched by Annals of Vascular Surgery. There is a long list of conditions that can cause cauda equina syndrome (some of these are very rare) aortic dissection; arteriovenous malformation; numerous other rare space-occupying lesions (e.g. Stepping Down When I became editor-in-chief of The American Journal of Cardiology in June 1982, I certainly did not expect to still be in that position in June 2022, forty years later.More. J Am Coll Cardiol 2016; 68:1054. (The term "necropsy" is generally reserved for non-human Pathology Etiology. The presentation is non-specific with fever, pain and weight loss. Symptoms often come on gradually with a decreased ability to exercise often occurring first. (8/20) of the FBN1 mutations in exons 59-65 are associated with a mild phenotype characterized by a lack of aortic root pathology. Oligometastasis - The Special Issue, Part 1 Deputy Editor Dr. Salma Jabbour, Vice Chair of Clinical Research and Faculty Development and Clinical Chief in the Department of Radiation Oncology at the Rutgers Cancer Institute of New Jersey, hosts Dr. Matthias Guckenberger, Chairman and Professor of the Department of Radiation Oncology at the University Hospital There are patient risks and potential life-threatening situations that may occur if a dilated aortic root progresses to the point of rupture, tear or dissection.

To improve our understanding of ATAA pathogenesis, we aimed to comprehensively characterize the cellular composition of the ascending aortic 26(8):942-5. The pericardial sac is composed of the thin visceral pericardium which consists of a single layer of cells adherent to the cardiac epicardium and the thicker, fibrous parietal pericardium composed of collagen and elastin which is adherent to the lungs, Carotid artery dissection is a separation of the layers of the artery wall supplying oxygen-bearing blood to the head and brain and is the most common cause of stroke in young adults. Adult:Video presenting the case of a 64-year-old female patient with Crawford Extent III TAAA who received TAAA open repair with a pre-sewn multi-branched aortic graft manufactured using two guides (visualization and marking guides) made with 3D printing technique.The process of constructing the aortic graft and TAAA open repair with it are shown. While uncommon, acute aortic dissection (AAD) is a rare but catastrophic disorder. vasculitis) of the aortic wall.. Clinical presentation. Ferroptosis is a new form of regulated cell death (RCD) driven by iron-dependent lipid peroxidation, which is morphologically and mechanistically distinct from other forms of RCD including apoptosis, autophagic cell death, pyroptosis and necroptosis. The aetiology of aortic aneurysm/dissection (AAD) derives from inability of vascular wall to withstand high intraluminal pressure, resulting in the dilation of aortic wall (aneurysm), disruption of medial layer (dissection), or in the worst case scenario, rupture of aneurysm and sudden death. The Journal of Cardiovascular Computed Tomography is a unique peer-review journal that integrates the entire international cardiovascular CT community including cardiologist and radiologists, from basic to clinical academic researchers, to private practitioners, engineers, allied professionals, industry, and trainees, all of whom are vital and interdependent members of our : 191, 204 The transition from ascending aorta to aortic Background: Ascending thoracic aortic aneurysm (ATAA) is caused by the progressive weakening and dilatation of the aortic wall and can lead to aortic dissection, rupture, and other life-threatening complications. It often begins as short periods of abnormal beating, which become longer or continuous over time. 441.0 Aortic Dissection; 441.3 Abdominal Aortic Aneurysm, ruptured; 441.4 Abdominal aortic Aneurysm, w/o rupture; 441.9 Abdominal Aortic Aneurysm, unspecified; 442 Other aneurysm; 443 Other peripheral vascular disease. Ferroptosis is a new form of regulated cell death (RCD) driven by iron-dependent lipid peroxidation, which is morphologically and mechanistically distinct from other forms of RCD including apoptosis, autophagic cell death, pyroptosis and necroptosis. Dissection may occur after physical trauma to A thoracic aorta greater than 4.5 cm is generally defined as aneurysmal, while a size greater than 6 cm is the distinction for treatment, which can be either endovascular or surgical, with the former reserved for pathology at the descending aorta. Aortic dissection is the prototype and most common form of acute aortic syndromes and a type of arterial dissection.It occurs when blood enters the medial layer of the aortic wall through a tear or penetrating ulcer in the intima and tracks longitudinally along with the media, forming a second blood-filled channel (false lumen) within the vessel wall. The major life-threatening cardiovascular complications--aneurysm of the aorta and aortic dissection--were reported in single cases by Baer et al. 'partition'), is a sheet of internal skeletal muscle in humans and other mammals that extends across the bottom of the thoracic cavity.The diaphragm is the most important muscle of respiration, and separates the thoracic cavity, containing the heart and lungs, from Changing Pathology of the Thoracic Aorta From Acute to Chronic Dissection: Literature Review and Insights. Aortic dissection-in pursuit of a serum marker. Montaner J et al. Pathology Etiology. AJOG's Editors have active research programs and, on occasion, publish work in the Journal. We have to be very careful with how were going to watch these aneurysms, states Dr. Castro. sarcoid) Risk factors. Abdominal aortic aneurysms (AAA) are focal dilatations of the abdominal aorta measuring 50% greater than the proximal normal segment, or >3 cm in maximum diameter. Aortic stenosis (AS or AoS) is the narrowing of the exit of the left ventricle of the heart (where the aorta begins), such that problems result. Oligometastasis - The Special Issue, Part 1 Deputy Editor Dr. Salma Jabbour, Vice Chair of Clinical Research and Faculty Development and Clinical Chief in the Department of Radiation Oncology at the Rutgers Cancer Institute of New Jersey, hosts Dr. Matthias Guckenberger, Chairman and Professor of the Department of Radiation Oncology at the University Hospital Radiology Across Borders Is delighted to be partnering with Diagnostic Imaging Pathways (DIP). A pericardial effusion refers to the accumulation of fluid in the pericardial sac surrounding the heart. Recently, ferroptosis has been found to participa If heart failure, loss of consciousness, or From the Editor in Chief (interim), Subhash Banerjee, MD. BAV is the most common cause of heart disease present at birth and affects approximately 1.3% of adults. An autopsy (post-mortem examination, obduction, necropsy, or autopsia cadaverum) is a surgical procedure that consists of a thorough examination of a corpse by dissection to determine the cause, mode, and manner of death or to evaluate any disease or injury that may be present for research or educational purposes. For example, larger patients will have larger aortic roots. Causes of death can be structured into immediate causes of death or primary causes of death, conditions leading to cause of death, underlying causes, and further relevant conditions that may have contributed to fatal outcome. J Am Coll Cardiol 2016; 68:1054. 2008/10. A panel of biomarkers including caspase-3 and D-dimer may differentiate acute stroke from stroke-mimicking conditions in the emergency department. Our doctors define difficult medical language in easy-to-understand explanations of over 19,000 medical terms. Aortic dissection occurs once per 10,000 patients admitted to the hospital; approximately 2000 new cases are reported each year in the United States. The Journal of Emergency Medicine is an international, peer-reviewed publication featuring original contributions of interest to both the academic and practicing emergency physician.JEM, published monthly, contains research papers and clinical studies as well as articles focusing on the training of emergency physicians and on the practice of emergency congenital or acquired spinal canal stenosis 3; The feared complication is rupture which is a surgical emergency due to its high mortality. x Primary focal hyperhidrosis (PFH) is a disorder characterized by regional sweating exceeding the amount required for thermoregulation [16]. Bicuspid aortic valve (aka BAV) is a form of heart disease in which two of the leaflets of the aortic valve fuse during development in the womb resulting in a two-leaflet (bicuspid) valve instead of the normal three-leaflet (tricuspid) valve. An acute aortic dissection is associated with very It may develop in multiple regions such as axillae, palms, soles and craniofacial [13] and usually appears during childhood with an estimated prevalence of 3% [2, 5]. ( Dissection is a blister-like de-lamination between the outer and inner walls of a blood vessel, generally originating with a partial leak in the inner lining.). It runs through a common pericardial sheath with the pulmonary trunk.These two blood vessels twist around each other, causing the aorta to start out posterior to the pulmonary trunk, but end by twisting to its right and anterior side. Aortic dissection is defined as a tear in the innermost layer of the aortic wall (ie, intima), which results in high-pressure blood flow between the layers of t Peterss S, Mansour AM, Ross JA, et al. It may also start as other forms of arrhythmia such as atrial flutter that then transform into AF. The new surgical journal seeks high-quality case reports, small case series, novel techniques, and innovations in all aspects of vascular disease, including arterial and venous pathology, trauma, arteriovenous syphilitic aortitis Imaging has a key role in active surveillance. DIP is an online suite of evidence-based and consensus-based imaging guidelines and an educational tool, developed in Western Australia with the aim guiding the appropriate choice of diagnostic imaging in clinical situations. It may occur at the aortic valve as well as above and below this level. Am J Emerg Med. Aortic dissection is defined as a tear in the innermost layer of the aortic wall (ie, intima), which results in high-pressure blood flow between the layers of t Peterss S, Mansour AM, Ross JA, et al. Dear Readers, Contributors, Editorial Board, Editorial staff and Publishing team members, From the Editor. The ascending aorta begins at the opening of the aortic valve in the left ventricle of the heart.
