Acute aortic dissection

BACKGROUND: The prognostic impact of atrial fibrillation (AF) and oral anticoagulation (OAC) therapy in patients with type B acute aortic dissection (AAD) remains unclear. Therefore, we investigated the prognostic impact of AF and OAC therapy in patients with type B AAD. METHODS: Consecutive patients diagnosed with AAD were included in this single-center, retrospective study. Patients with type B AAD were selected from the study population and divided into three groups: AF(+)/OAC(+), AF(+)/OAC(-), and AF(-)/OAC(-)...

Intensive care physicians are tasked with managing patients with complex organ disorders, necessitating a broad skill set and ongoing education. While simulation training often focuses on equipment handling, this case report highlights a critical instance of acute aortic dissection initially missed on imaging during intensive care unit (ICU) admission. An 86-year-old woman with multiple comorbidities presented with respiratory symptoms and electrolyte imbalances, ultimately requiring ICU admission. Despite initial inconclusive imaging and treatment for suspected conditions, further evaluation revealed a dissecting aneurysm of the descending aorta...

Right ventricular failure is a mechanism of hemodynamic collapse in acute aortic dissection. Mostly RV failure happens as a result of coronary malperfusion secondary to compression of right coronary artery ostium by the false lumen of type A aortic dissection or the dissection flap involving this coronary artery. Another mechanism is compression of pulmonary artery and an acute rise of pulmonary pressure below the level of obstruction, which is rarely reported. Herein, we presented an 82-year-old man who was admitted with type A aortic dissection in whom echocardiographic examination revealed right pulmonary artery compression resulting in acute right ventricular failure...

BACKGROUND: Kampo, a Japanese herbal medicine, is approved for the treatment of various symptoms/conditions under national medical insurance coverage in Japan. However, the contemporary nationwide status of Kampo use among patients with acute cardiovascular diseases remains unknown.Methods and Results: Using the Japanese Diagnosis Procedure Combination database, we retrospectively identified 2,547,559 patients hospitalized for acute cardiovascular disease (acute myocardial infarction, heart failure, pulmonary embolism, or aortic dissection) at 1,798 hospitals during the fiscal years 2010-2021...

OBJECTIVE: The purpose of this study was to assess whether the presence of an aneurysmal or dissecting arterial disease was a risk factor of poor prognosis in patients presenting a dissection of the celiac trunk (CT). METHODS: All patients presenting a CT dissection between January 1, 2014 and June 30, 2022 were included. Patients with a CT dissection due to the extension of an aortic dissection were excluded. Les antécédents familiaux de dissection, de maladie anévrysmale, de maladie athéromateuse ou du tissu conjonctif, la pratique d'une activité physique ou sportive, un effort inhabituel les jours précédant la dissection ainsi qu'un traumatisme étaient recherchés...

BACKGROUND: The management of hemostasis in patients medicated with apixaban (Eliquis) undergoing emergency cardiac surgery is exceedingly difficult. The body's natural elimination pathways for apixaban prove ineffective in emergency situations, and the impact of hemodialysis is limited. The application of Cytosorb® may attenuate the concentration of apixaban, thereby facilitating the stabilization of these patients. CASE PRESENTATION: An 84-year-old man treated with apixaban, underwent emergency ascending aorta replacement surgery due to an acute type A aortic dissection...

BACKGROUND: Acute type A aortic dissection (ATAAD) complicated by mesenteric malperfusion is a critical and complicated condition. The optimal treatment strategy remains controversial, debate exists as to whether aortic dissection or mesenteric malperfusion should be addressed first, and the exact time window for mesenteric ischemia intervention is still unclear. To solve this problem, we developed a new concept based on the pathophysiological mechanism of mesenteric ischemia, using a 6-hour time window to divide newly admitted patients by the time from onset to admission, applying different treatment protocols to improve the clinical outcomes of patients with ATAAD complicated by mesenteric malperfusion...

The potential of adverse events (AEs) after thoracic endovascular aortic repair (TEVAR) in patients with type B aortic dissection (TBAD) has been reported. To avoid the occurrence of AEs, it is important to recognize high-risk population for prevention in advance. The data of 261 patients with TBAD who received TEVAR between June 2017 and June 2021 at our medical center were retrospectively reviewed. After the implementation of exclusion criteria, 172 patients were finally included, and after 2.8 years (range from 1 day to 5...

INTRODUCTION: Fenestrated and branched thoracic endovascular repair (f/bTEVAR) have been successfully applied in patients with diverse aortic arch pathologies. The aim of this study is to present the early and mid-term outcomes of patients with native proximal aortic landing (NPAL) managed with f/bTEVAR. METHODS: A single-center retrospective analysis of patients with NPAL, managed with f/bTEVAR, between September 1st , 2011, and June 30th , 2022, was conducted...

Aortic dissection (AD) is a rare but often lethal condition if not properly and urgently treated. Most often, patients arrive with acute hemodynamic instability and ripping chest agony. The patient's life depends critically on a correct diagnosis made as soon as possible. We describe a 60-year-old man who arrived at the emergency room with symptoms of a brain stroke, including poor consciousness, left-sided weakness, and speech disturbance associated with hemodynamic instability, and chest pain. Thoracic aortic arch dissection was observed on CT angiography (CTA)...

BACKGROUND: Recently the SVS and STS published contemporary guidelines clearly defining complicated vs uncomplicated acute type B aortic dissections (TBADs) with an additional high-risk grouping. Few studies have evaluated outcomes associated with "high-risk" TBADs. The objective of this study was to assess differences in demographics, clinical presentation, symptom onset, and outcomes in high-risk patients that underwent either thoracic endovascular aortic repair (TEVAR) or best medical management for acute TBAD compared to those with complicated and uncomplicated acute TBAD...

TEVAR for type IIIb aortic dissection achieves the disappearance of false lumen perfusion in the abdominal aorta in only about 20% of cases, with concern for expansion in the long term. Staged endovascular therapy with intervention on all re-entries can lead to complete false lumen thrombosis and remodelling of the entire aorta. This approach could be an option in cases where long-term expansion is anticipated.

BACKGROUND AND AIMS: Studies on the impact of syphilis on the cardiovascular system in large populations are limited. This study investigated the effects of syphilis on cardiovascular outcomes. METHODS: Medical records from 2010 to 2015 were retrieved from the Taiwan National Health Insurance Research Database, linked to the Notifiable Infectious Diseases database from the Taiwan Centers for Disease Control. Patients with syphilis were identified, excluding those with missing information, under 20 years of age, or with a history of human immunodeficiency virus infection, acute myocardial infarction, heart failure, aortic regurgitation, replacement of the aortic valve, aneurysm and/or dissection of the aorta, atrial fibrillation, ischaemic stroke, haemorrhagic stroke, and venous thromboembolism...

Acute aortic dissection in unusual/rare circumstances may become chronic and multi lumen. A high clinical acumen, examination and investigations in the acute setting, may help reduce late/misdiagnosis and complications in low resource settings.

BACKGROUND: Acute Type A aortic dissection (ATAAD) is a life-threatening cardiovascular disease associated with high mortality rates, where surgical intervention remains the primary life-saving treatment. However, the mortality rate for ATAAD operations continues to be alarmingly high. To address this critical issue, our study aimed to assess the correlation between preoperative laboratory examination, clinical imaging data, and postoperative mortality in ATAAD patients. Additionally, we sought to establish a reliable prediction model for evaluating the risk of postoperative death...

We aimed to evaluate the association between air pollutants and mortality risk in patients with acute aortic dissection (AAD) in a longitudinal cohort and to explore the potential mechanisms of adverse prognosis induced by fine particulate matter (PM2.5). Air pollutants data, including PM2.5, PM10.0, nitrogen dioxide (NO2 ), carbon monoxide (CO), sulfur dioxide (SO2 ), and ozone (O3 ), were collected from official monitoring stations, and multivariable Cox regression models were applied. Single-cell sequencing and proteomics of aortic tissue were conducted to explore the potential mechanisms...

Aortic pathologies encompass a heterogeneous group of disorders, including acute aortic syndrome, traumatic aortic injury , aneurysm, aortitis, and atherosclerosis. The clinical manifestations of these disorders can be varied and non-specific, ranging from acute presentations in the emergency department to chronic incidental findings in an outpatient setting. Given the non-specific nature of their clinical presentations, the reliance on non-invasive imaging for screening, definitive diagnosis, therapeutic strategy planning, and post-intervention surveillance has become paramount...
