OBJECTIVES: Surgical repair of aneurysmal disease involving the ascending aorta, aortic arch and eventually the descending aorta is generally associated with significant morbidity and mortality. A less invasive approach with the ascending wrapping technique (WT), supra-aortic vessel debranching (SADB) and thoracic endovascular aneurysm repair (TEVAR) in zone 0 was developed to reduce the associated risk in these patients. METHODS: During a 10-year period, consecutive patients treated by the ascending WT, SADB and TEVAR in zone 0 were included...

Giant cell arteritis ( GCA) is an inflammatory vasculopathy affecting large and middle-sized vessels , specifically cranial arteries derived from carotid artery. Isolated extracranial vessel involvement can occur. Interest in extravascular manifestations is recently increasing because of diffusion of sensitive and specific imaging tools such as 18FDG PET TC . Patients have an increased relative risk of severe infection. Listeria monocytogenes infection risk is increased, and vascular system involvement and graft infection have been, even though rarely, reported...

We describe the case of a 23-year-old white female, 10-12 weeks pregnant, with a history of intravenous drug use and a recently diagnosed pneumonia, who was found deceased in her bed after a night of sleep. Although postmortem serum toxicology tested positive for alprazolam, tetrahydrocannabinol, and morphine, the ultimate cause of death was determined to be cardiac tamponade secondary to an isolated abscess in the ascending aorta. The patient had several risk factors for aortic rupture and cardiac tamponade including intravenous drug use, pneumonia, and pregnancy...

Aortic dissection is a life threatening cardiovascular catastrophy. Its incidence estimated to 5-6 cases per 100,000 patients/year. The intimal tear happens at the ascending aorta in Type A, meanwhile at the aortic isthmus in Type B, but entry point may develop anywhere alongside the entire aorta. All types may affect a short aortic segment resulting in a localized false aneurysm, others separate the intimal layer at longer extension down to the visceral segment and far beyond to the femoral arteries. Dissection of orifices of side branches may lead to cerebral, upper extremity, spinal, visceral, renal and lower extremity malperfusion...

Aortic dissection is a life-threatening condition in which early diagnosis, treatment and close follow up are critical for survival. Between 60% and 70% of patients with acute aortic dissection are affected at the ascending aorta, classified as Stanford type A (TAD). Preventive surgery of the aorta in asymptomatic patients on the basis of aortic size alone remains controversial among patient populations without known risk factors for aortic dissection. In fact, many dissection patients do not appear to have markedly dilated aortas at the time of presentation...

BACKGROUND: Alternative access for thoracic endovascular aortic repair (TEVAR) has been explored for patients with unsuitable femoral and iliac access, but few cases of transapical access have been described. We report our experience with transapical access for various aortic pathologies. METHODS: We reviewed six cases undergoing transapical access for endovascular repair of thoracic aortic pathology between December 2013 and August 2015. Five patients had an aortic arch aneurysm and 1 patient presented with Stanford type A subacute aortic dissection...

OBJECTIVE: The purpose of this case report was to describe chiropractic management of thoracic pain in a patient with a stable thoracic aortic aneurysm. CLINICAL FEATURES: An 89-year-old man presented with axial mid- and upper back pain localized predominantly at the T8 and T1 spinal segmental levels. A review of available imaging revealed a stable aneurysmal dilatation of the ascending aorta, which measured 4.3 cm. INTERVENTION AND OUTCOME: Because the thoracic pain was musculoskeletal in nature and the thoracic aortic aneurysm was stable, mechanical manipulation was provided using the Impulse adjusting instrument...

Transthoracic echocardiography ( TTE transthoracic echocardiography ) is a critical tool in the field of clinical cardiology. It often serves as one of the first-line imaging modalities in the evaluation of cardiac disease owing to its low cost, portability, widespread availability, lack of ionizing radiation, and ability to evaluate both anatomy and function of the heart. Consequently, a large majority of patients undergoing a cardiac computed tomography (CT) or magnetic resonance (MR) imaging examination will have a TTE transthoracic echocardiography available for review...

OBJECTIVE: Hemodynamics related to eccentric blood flow may factor into the development of bicuspid aortic valve aortopathy. We investigated wall shear stress distribution by means of magnetic resonance imaging-based computational fluid dynamics in patients with a bicuspid aortic valve. METHODS: Included were 12 patients with a bicuspid aortic valve (aortic stenosis, n = 11; root enlargement, n = 1). Three patients with a normal tricuspid aortic valve (arch aneurysm, n = 1; descending aortic aneurysm, n = 2) were included for comparison...

BACKGROUND: Bicuspid aortic valve (BAV) is associated with asymmetric dilatation of the proximal ascending aorta. We previously demonstrated increased susceptibility of smooth muscle cells to oxidative stress in the BAV-aneurysmal aorta and hypothesized that antioxidant expression is regionally defined and influenced by the BAV morphotype. METHODS: BAV valve morphology was defined according to number of raphes: type 0 (0 raphes), type 1 (1 raphe), or type 2 (2 raphes) and by the raphe location among the left (L), right (R) or non (N) coronary cusps...

Marfan syndrome commonly affects the skeletal, ocular, and cardiovascular systems. Involvement of the gastrointestinal system is known but uncommon. Intervention depends upon the system involved and the severity of symptoms. Special awareness is required for the diagnosis and management of gastrointestinal involvement in these patients. We report a rare case of simultaneous surgical repair of an ascending aortic aneurysm and a type IV hiatal hernia in a 35-year-old man with Marfan syndrome.

Bicuspid aortic valve (BAV)-associated ascending aneurysmal aortopathy (namely "bicuspid aortopathy") is a heterogeneous disease making surgeon predictions particularly challenging. Computational flow analysis can be used to evaluate the BAV-related hemodynamic disturbances, which likely lead to aneurysm enlargement and progression. However, the anatomic reconstruction process is time consuming so that predicting hemodynamic and structural evolution by computational modeling is unfeasible in routine clinical practice...

OBJECTIVE: Bicuspid aortic valve anatomy is associated with ascending aortic aneurysm in approximately 50% of individuals and may lead to severe aortic regurgitation with aortic dilatation. Both entities may be treated by valve repair and root remodeling. The objective was to review the cumulative experience of 20 years. METHODS: Between November 1995 and December 2015, 357 patients (324 male; age 10-80 years; mean, 49 ± 13 years) underwent combined bicuspid aortic valve repair and root remodeling...

REVIEW
Anitha Parthiban, Girish Shirali
Echocardiography is the primary modality for imaging the aorta for the diagnosis and serial evaluation of pathological conditions. In this article, we review the methodology for optimal echocardiographic imaging of the various segments of the aorta and discuss abnormalities of the aorta including stenosis, dilation including aortopathy and sinus of Valsalva aneurysms, and fistulous communications involving the ascending aorta including aortoventricular tunnel and ruptured sinus of Valsalva aneurysm. We review novel echocardiographic measurements of aortic functional properties of the aorta such as elasticity and stiffness, and review the literature on the potential additive value of such measurements for structural assessment alone...
