BACKGROUND: Idiopathic aortitis became recognized relatively recently, and the body of knowledge concerning this condition is scarce. We aimed to determine the frequency of idiopathic aortitis in aortic specimens, the clinical, laboratory and radiologic characteristics at diagnosis and during follow-up, and the approach to investigation, treatment and monitoring taken by the treating physicians. METHODS: We identified cases of aortitis diagnosed on pathological specimens of the aorta between Jan...

Aortic dissection is a life threatening condition. Hybrid repair has been described for the treatment of complex aortic pathology such as thoracoabdominal aortic aneurysms (TAAA) and type A and B dissections, although open and total endovascular repair are also possible. Open surgery is still associated with substantial perioperative morbi-mortality rates, thus less invasive techniques such as endovascular repair and hybrid procedures can achieve good results in centers with experience. We present the case of a patient with a chronic type B dissection and TAAA degeneration that was treated in a single stage hybrid procedure with antegrade supra-aortic and renovisceral debranching from the ascending aorta and TEVAR...

REVIEW
José María González-Santos, María Elena Arnáiz-García
Dilatation of the ascending aorta (AA) is a common finding in patients with aortic valve disease. The clinical practice guidelines recommend replacing the AA whenever the diameter exceeds 45 mm. However, no consensus has been reached regarding the approach when the aorta is only moderately dilated. Although the risk in aorta replacement is generally low, it may be higher when associated with other complex surgical procedures or it is carried out in elderly patients or patients with significant comorbidity. This would justify the use of alternative surgical techniques, which reduce surgical risk and guarantee a durable correction of the aortic pathology...

OBJECTIVES: To explore whether the serum concentration of adrenaline (AD) and noradrenaline (NA) elevate and its correlation with oxygenation index (OI) in the patients of acute aortic dissection (AAD). METHODS: From April 2013 to December 2013, clinical data were collected from three groups of patients (38 cases of AAD in Group A, 28 cases of ascending aortic aneurysm in Group B, and 22 cases of angina in Group C). All patients received the measurement of serum concentrations of AD, NA and endotoxin (ET)...

OBJECTIVE: In patients presenting with aortic valvulopathy with concomitant ascending aortic aneurysm, surgical management of the sinus of Valsalva segment remains undefined, especially for moderately dilated aortic roots. In patients with this pathology undergoing aortic valve replacement with supracoronary ascending aorta replacement, we assessed the fate of the remnant preserved sinus of Valsalva segment stratified by aortic valve morphology and pathology. METHODS: From 2002 to 2015, 428 patients underwent elective aortic valve replacement with supracoronary ascending aorta replacement...

BACKGROUND: In this study, the effect of aortic valve (AV) pathology on local hemodynamic conditions was evaluated as a potential trigger for the onset of acute type A and B aortic dissection. METHODS: A time- and pressure-related four-dimensional (4-D) computed fluid dynamic model of the aorta was established. In an experimental setup, AV stenosis and AV insufficiency were created. 4-D pressure-related geometry of the aortic root (AR) with valve insufficiency and valve stenosis were determined by high-fidelity (200 Hz) microsonometric crystals...

Thoracic aortic pseudoaneurysms are a recognized complication following aortic arch replacement. The established first line treatment is surgical repair; however, this may not be feasible in all patients. Percutaneous treatment of ascending thoracic pseudoaneurysms has been described as an alternative for nonsurgical candidates. Utilization of multimodality imaging can prove invaluable in minimizing the risk of potentially fatal intra-procedural complications. We present a case of successful embolization using computer tomography-guided direct percutaneous puncture of the pseudoaneurysm, with concomitant endovascular treatment under fluoroscopic and intravascular ultrasound guidance in a patient with challenging vascular anatomy...

OBJECTIVES: Our aim was to report outcome of patients with acute non-A non-B aortic dissection involving the aortic arch but not the ascending aorta. METHODS: Dissection extension and entry location were analysed in patients with acute aortic dissection admitted between 2001 and 2016 at a tertiary centre. Non-A non-B dissection was classified as descending-entry type with entry distal to the left subclavian artery and dissection extending into the aortic arch, and arch-entry type with entry between the innominate and left subclavian arteries...

A 44-year-old woman was admitted for chest distress. Computed tomography angiography showed a 3.6-cm IAA arising from the aortic arch and compressing the trachea. A median sternotomy was performed with the patient under general anesthesia, and the IAA was found to involve the origin of the innominate artery and the bifurcation of the right subclavian artery and common carotid artery; however, the aorta was intact...

Mutations in lysyl oxidase (LOX) are associated with thoracic aortic aneurysm and dissection (TAAD). Mice that do not express Lox (Lox(-/-)) die soon after birth and have 60% and 40% reductions in elastin- and collagen-specific crosslinks, respectively. LOX inactivation could also change the expression of secreted factors, structural matrix, and matrix-associated proteins that constitute the aortic matrisome. We hypothesize that the absence of Lox will change the mechanical behavior of the aortic wall due to reduced elastin and collagen crosslinking and alter the expression levels of matrisome and smooth muscle cell (SMC) genes in a vascular location-specific manner...

Spontaneous rupture of the aorta through an atherosclerotic lesion without preexisting aortic aneurysm, dissection, or history of trauma is very rare. Without prompt aortic repair, all cases result in sudden death with a definitive diagnosis made only intraoperatively or during autopsy. The phenomenon has been uniformly found in individuals with hypertension. The author reports a sudden unexpected death caused by spontaneous rupture of the ascending aorta in a 57-year-old man with a history of hypertension...

Bicuspid aortic valve is traditionally considered an innocuous congenital anomaly. Due to a better and widespread availability of non-invasive imaging techniques, it has come to the fore that 30% of these cases develop complications, viz., valve abnormality (aortic regurgitation and stenosis), and aneurysm of aortic root and ascending aorta. Sinus of Valsalva aneurysm is an uncommon complication of bicuspid aortic valve and more so those arising from the left coronary sinus are the rarest. These complications generally occur in the third or fourth decade of life...

BACKGROUND: The ascending aorta is an uncommon site for non-infective thrombus. In non-aneurysmal and non-atherosclerotic vessels this condition becomes extremely rare, while it represents a source of potential cerebral and peripheral embolic events. Currently, there is no consensus in the guidelines on how to treat a free floating thrombus in ascending aorta, therefore we present our decision making process and therapeutic strategy. CASE PRESENTATION: A healthy 48-year-old man was hospital admitted with acute abdominal pain...

BACKGROUND: Ascending thoracic aortic aneurysm (aTAA) is a heterogeneous group of disorders that involve impaired endothelial function. The nitric oxide (NO) synthase inhibitor asymmetric dimethylarginine (ADMA) serves as an endothelial dysfunction marker. Thus, we investigated ADMA levels in patients with aTAA. METHODS: Eighty-six patients with aTAA and 18 healthy individuals were enrolled. All patients underwent echocardiography. Plasma ADMA levels were measured using high-performance liquid chromatography...

INTRODUCTION: Epiaortic ultrasound scanning (EAS) extended the use of ultrasound to the intraoperative diagnosis of aortic pathology. Surgical palpation of the ascending aorta underestimates the presence and severity of atherosclerotic plaques. Epiaortic ultrasound scanning has been used as an adjunct to transesophageal echocardiography (TEE) or as a primary direct diagnostic tool for imaging the ascending aorta as well as the aortic arch, which gained prominence as part of a multipronged intraoperative strategy to reduce atherosclerotic emboli...

Homozygous or compound heterozygous mutations in fibulin-4 (FBLN4) lead to autosomal recessive cutis laxa type 1B (ARCL1B), a multisystem disorder characterized by significant cardiovascular abnormalities, including abnormal elastin assembly, arterial tortuosity, and aortic aneurysms. We sought to determine the consequences of a human disease-causing mutation in FBLN4 (E57K) on the cardiovascular system and vascular elastic fibers in a mouse model of ARCL1B. Fbln4(E57K/E57K) mice were hypertensive and developed arterial elongation, tortuosity, and ascending aortic aneurysms...
