BACKGROUND: Endovascular arch repair technology is driven in large part by the assumption that open arch operations are high-risk. We wanted to evaluate the clinical results of open arch reconstruction in the modern era in a large group practice. METHODS: From October 2003 to June 2014, 567 patients underwent aortic arch operations: hemiarch repair was performed in 429 patients (75.7%; group A), total arch repair in 129 (22.7%; group B), and patch repair in the remaining 9 (1...

Disorders associated with the hepatitis C virus (HCV) have been reported including cardiovascular, metabolic, and central nervous system diseases. Since chronic HCV infections may be curable, their identification as causal contributors to cardiovascular risk could offer new perspectives in the prevention of cardiovascular disease. The aim of this study is to investigate the association between HCV and aortic arch calcification (AAC) and corneal and conjunctival calcification (CCC) in maintenance hemodialysis (MHD) patients; further, we assessed the correlation of CCC with vascular calcification...

Laser speckle flowgraphy (LSFG) is an ophthalmologic equipment that qualitatively detects the blood flow of the optic nerve head, which is known to be related with cerebral microcirculation. LSFG can also measure the mean blur rate, which quantitatively calculates the blood flow. We aimed to assess the utility of LSFG in the evaluation of cerebral perfusion during aortic surgery under hypothermic circulatory arrest with retrograde and antegrade cerebral perfusion. Two patients underwent total arch replacement for aneurysm...

BACKGROUND: Bicuspid aortic valve (BAV) occurs both as an isolated cardiac lesion and in association with congenital heart defects (CHD). Their aim was to identify the incidence and morphology of BAV in patients with coexisting CHD and compare their disease progression to patients with isolated BAV. METHODS: The Mayo Clinic echocardiography database was retrospectively analyzed to identify pediatric and young adult patients (≤22 years) who were diagnosed with BAV from 1990 to 2015...

Traumatic injury of the left common carotid is rare but severe disease, and is an uncommon situation in emergency units. Thoracic aortic lesions are often associated with other injuries, making their treatment challenging. We report the case of a successful hybrid approach to treat this lesion using a total supra aortic vessels debranching and a thoracic endovascular graft to cover the rupture, in a 38 years old polytraumatized patient. After aortic, abdominal and orthopaedic surgery, the patient recovered well...

OBJECTIVE: To describe a total endovascular aortic repair with branched and fenestrated endografts in a young patient with Marfan syndrome and a chronic aortic dissection. Open surgery is the gold standard to treat aortic dissections in patients with aortic disease and Marfan syndrome. METHODS: In 2000, a 38-year-old man with Marfan syndrome underwent open ascending aorta repair for an acute type A aortic dissection. One year later, a redo sternotomy was performed for aortic valve replacement...

Aberrant left vertebral artery (LVA) origin off the aortic arch is an uncommon anatomic variant. Treatment of the thoracic aortic pathology that necessitates its coverage has not been described. We present a patient with an acute intramural hematoma with a dominant LVA originating from the aortic arch. A LVA-to-carotid artery transposition with shunt placement, carotid-to-subclavian bypass, and thoracic endovascular aortic repair were performed. The patient recovered uneventfully, without any evidence of stroke...

REVIEW
Michael Dattilo, Valérie Biousse, Nancy J Newman
Central retinal artery occlusion (CRAO) is caused by partial or complete occlusion of the central retinal artery, most commonly by an embolus from the ipsilateral carotid artery, aortic arch, or heart, and is the ocular equivalent of an acute cerebral ischemic event. The risk factors for a CRAO and acute cerebral ischemia are very similar, if not identical. Because no current therapeutic intervention has been shown to improve visual outcomes compared with the natural history of CRAO, management of CRAO should be focused on secondary prevention of vascular events, such as cerebral ischemia, myocardial infarction, and cardiovascular death...

Vascular mechanics assessed with two-dimensional speckle tracking echocardiography (2D-STE) could be used as a new imaging surrogate of vascular stiffening. The CHA2DS2-VASc score is considered accurate as an estimate of stroke risk in non-valvular AF, although many potential stroke risk factors have not been included in this scoring method. The purpose of this research is to study the feasibility of evaluating vascular mechanics at the descending aorta in non-valvular AF patients using transesophageal 2D-STE and to analyze the association between descending aortic mechanics and stroke...

BACKGROUND: Stanford type A acute aortic dissection (A-AAD) extends to the brachiocephalic branches in some patients. After ascending aortic replacement, a remaining re-entry tear in the distal brachiocephalic branches may act as an entry and result in a patent false lumen in the aortic arch. However, the effect of brachiocephalic branch re-entry concomitant with A-AAD remains unknown.Methods and Results:Eighty-five patients with A-AAD who underwent ascending aortic replacement in which both preoperative and postoperative multiple-detector computed tomography (MDCT) scans could be evaluated were retrospectively studied...

Young patients with bicuspid aortic valve disease and aortopathy remain a clinical challenge, with many requiring multiple corrective operations throughout their lifetimes. Innovative surgical approaches are often required to address complex aortic pathologic conditions but leave patients at risk for reintervention, lifelong anticoagulation, and suboptimal hemodynamics. We describe an active 44-year-old female triathlete with recurrent bicuspid aortic stenosis, a small aortic root, a hypoplastic aortic arch and complex distal arch, and a descending aortic aneurysm, who underwent a single-stage reconstruction with a combined Ross procedure, hybrid arch, and frozen elephant trunk reconstruction...

AIMS: Risk models that use a single aortic diameter threshold have failed to successfully predict acute type B aortic dissection (TBAD). We sought to identify meaningful age-indexed anatomical variables to predict TBAD risk. METHODS AND RESULTS: A geometric deformable model, consisting of virtual elastic balloons that inflate inside a vessel lumen, was developed to quantify thoracic aorta geometry. In the presence of TBAD, true and total artery lumen morphology were assessed...

BACKGROUND: Various techniques are described to facilitate stable stent implantation in aortic arch stenosis or coarctation. We describe an alternative technique, which due to its unique appearance during stent implantation, we have named "Dog Bone Technique" (DBT). TECHNIQUE: The stent/balloon assembly is placed across the stenosis, the long sheath is retrieved to uncover the distal 20-50% of the stent. The balloon is inflated with the pressure inflator just to expand slightly the stent...

It is challenging to evaluate aortopathy in congenital heart disease using conventional investigations such as brachial-ankle pulse wave velocity (baPWV). Therefore, we evaluated the cardio-ankle vascular index (CAVI), a dimension of the ascending aorta and plasma transforming growth factor-β1 (TGF-β1) level, in order to find novel noninvasive parameters of aortopathy in adults with repaired tetralogy of Fallot (TOF). Prospectively, we enrolled 42 consecutive adults with TOF (28 patients with repaired TOF were not on ARB, 8 patients with repaired TOF on ARB, 6 patients with no repair or only palliative repair) and 20 age-matched healthy controls...

PURPOSE: To describe the combined use of a tubular stent-graft for the ascending aorta and an inner-branched arch stent-graft for patients with acute type A aortic dissection. TECHNIQUE: The technique to deploy these modular, custom-made stent-grafts is demonstrated in 2 patients with acute DeBakey type I aortic dissections and significant comorbidities precluding open surgery. Both emergent procedures were made possible by the availability of suitable devices manufactured for elective repair in other patients...

Aortic arch aneurysm is a complex pathology which requires coverage of one or more aortic arch vessels. In this study we explore the hemodynamic behavior of the aortic arch in aneurysmatic and treated cases with three currently available treatment approaches: Surgery Graft, hybrid Stent-Graft and chimney Stent Graft. The analysis included four models of the time-dependent fluid domains of aneurysmatic arch and of the surgery, hybrid and chimney endovascular techniques. Dimensions of the models are based on typical anatomy, and boundary conditions are based on typical physiological flow...

AIMS/HYPOTHESIS: A recent large clinical study has shown that empagliflozin has a lower rate of cardiovascular and all-cause mortality when compared with placebo in patients with type 2 diabetes. We investigated the effect of empagliflozin (compared with glimepiride) on the progression of atherosclerosis, and its possible mechanisms of action. METHODS: Forty-eight 5-week-old male ApoE (-/-) mice were fed a western diet for 20 weeks and divided into four groups: control (saline, 154 mmol/l NaCl), glimepiride 0...
