Acute Aortic Dissection Type A : Age-related Management and Outcomes Reported in the German Registry for Acute Aortic Dissection Type A (GERAADA) of …

2013

To determine the association between age and clinical presentation, management and surgical outcomes in a large contemporary, prospective cohort of patients with acute aortic dissection type A (AADA).AADA is one of the most life-threatening cardiovascular diseases, and delayed surgery or overly conservative management can result in sudden death.The perioperative and intraoperative conditions of 2137 patients prospectively reported to the multicenter German Registry for Acute Aortic Dissection Type A were analyzed.Of all patients with AADA, 640 (30%) were 70 years or older and 160 patients (7%) were younger than 40 years. The probability of aortic dissection extension to the supra-aortic ves…

Detection of dissection of the aortic intima and media after angioplasty of coarctation of the aorta. An angiographic, computer tomographic, and echo…

1990

Balloon coarctation angioplasty (BCA) was performed in eight patients (five male and three female) who were 14-49 years old (mean, 27.3 years) with isolated discrete unoperated coarctation of the aorta (n = 7) and postoperative recoarctation (n = 1). BCA was successful in seven of eight patients, resulting in a decrease in the gradient (64 +/- 19 to 16 +/- 13 mm Hg, p less than 0.01), an increase in the diameter at the coarctation site (0.9 +/- 0.4 to 1.6 +/- 0.4 mm, p less than 0.01). Follow-up (6 months) has demonstrated continued gradient relief (6 +/- 9 mm Hg) and diameter increase (1.6 +/- 0.2 cm). Monitoring was performed by transesophageal echocardiography (TEE) during BCA, and befor…

Assessment of chronic aortic dissection: contribution of different ECG-gated breath-hold MRI techniques.

2004

Our objective was to evaluate the impact of different rapid MRI techniques for the assessment and follow-up of chronic aortic dissections.Fifty-three patients (41 postoperative Stanford type A, 12 type B dissections) were scanned at 1.5 T during a 3-year period. The study reviewed ECG-gated breath-hold black blood sequences and 3D contrast-enhanced MR angiography of the thoracic aorta supplemented by segmented cine and phase-contrast imaging as well as abdominal contrast-enhanced MR angiography. A retrospective separate analysis of black blood acquisitions and contrast-enhanced MR angiograms from a total of 72 examinations was performed by two radiologists to evaluate detection of intimal f…

Echocardiography in diagnosis of aortic dissection.

1989

In a multicentre study the accuracy of echocardiography was measured in 164 consecutive patients with suspected aortic dissection. The diagnosis was subsequently proven (82 patients) on the basis of transthoracic and transoesophageal echocardiography and additional diagnostic procedures, including computed tomography (CT), aortic angiography, and surgery and/or necropsy. The sensitivity and specificity of echocardiography were 99% and 98%, respectively, with positive and negative predictive values of 98% and 99%. For CT sensitivity was 83%, specificity 100%, and positive and negative predictive values 100% and 86%, respectively. For aortography sensitivity and specificity were 88% and 94%, …

COMPUTATIONAL FLUID DYNAMICS OF TYPE B AORTIC DISSECTION

2014

Type B aortic dissection (AoD) is a disease connected to high blood load on the aortic wall and to a reduced aortic wall resistance. Nowadays, prognosis on type B AoD results to be particularly difficult with an high incidence of patients treated with medical therapy which manifest complication connected with dissection and which should have been treated with surgical repair immediately. This work aims to study those haemodynamical and morphological proprieties of dissected aorta, which can influence the progression or stability of type B AoD. Computational fluid-dynamic analyses were performed on twenty-five patients with type B AoD, whose nine presented an aneurysm evolution and sixteen p…

Aneurysms and dissections - What is new in the literature of 2019/2020 - a European Society of Vascular Medicine annual review

2020

Summary: More than 6,000 publications were found in PubMed concerning aneurysms and dissections, including those Epub ahead of print in 2019, printed in 2020. Among those publications 327 were selected and considered of particular interest.

RUPTURE OF AN AORTIC DISSECTION INTO THE RIGHT ATRIUM IN A PATIENT WITH PREVIOUS AORTIC VALVE REPLACEMENT: A CASE REPORT

2005

We report the case of a 73-year-old man with a history of previous aortic valve replacement in 1990 and rupture of an aortic dissection into the right atrium. The patient was admitted to the emergency room because of chest pain, stopped not long after. The electrocardiogram did not show any signs of ischemia and myocardial enzymes were not increased. Transthoracic echocardiography revealed aortic root dilation (maximum diameter 60 mm) extended to the aortic arch, and the presence of a flow from the ascending aorta to the right atrium (evocative of a fistula between the two chambers). The aortic valvular prosthesis function was good. Transesophageal echocardiography confirmed an aorta-right …

Thoracic Endovascular Aortic Repair (TEVAR) for the treatment of aortic diseases: a position statement from the European Association for Cardio-Thora…

2012

Thoracic endovascular aortic repair (TEVAR) is an emerging treatment modality, which has been rapidly embraced by clinicians treating thoracic aortic disease.1–4 Fundamentally, it is a far less invasive approach than open surgery and its availability and relative ease of application has changed and extended management options in thoracic aortic disease, including in those patients deemed unfit or unsuitable for open surgery. In the operating room, this requires considerable perceptual, cognitive and psychomotor demands on the operators. The dramatic expansion of TEVAR activity has necessarily prompted a requirement to systematically consider the indications, appropriateness, limitations and…

Acute aortic dissection type A

2012

Abstract Background Acute aortic dissection type A (AADA) is a life-threatening vascular emergency. Clinical presentation ranges from pain related to the acute event, collapse due to aortic rupture or pericardial tamponade, or manifestations of organ or limb ischaemia. The purpose of this review was to clarify important clinical issues of AADA management, with a focus on diagnostic and therapeutic challenges. Methods Based on a MEDLINE search the latest literature on this topic was reviewed. Results from the German Registry for Acute Aortic Dissection Type A (GERAADA) are also described. Results Currently, the perioperative mortality rate of AADA is below 20 per cent, the rate of definitive…
