The technique for successful surgical correction of an anomalous origin of the right coronary artery from the opposite aortic cusp with an aberrant course between the aorta and pulmonary artery is illustrated in a symptomatic 62-year-old woman. The intramural course of the right coronary artery traversed the tip of the commissure between the anterior and posterior leaflets, and its repair entailed unroofing of the intramural segment from inside the aortic intima. This technique required resuspension of the overlying commissure to maintain optimal aortic valve leaflet coaptation and prevent aortic insufficiency...

OBJECTIVE: Stroke caused by cerebral embolization constitutes a principal risk during arch manipulation and thoracic endovascular aortic repair (TEVAR). This study investigates the incidence of cerebral embolization during catheter placement in the aortic arch, and compares robotic and manual techniques. METHODS: Intra-operative transcranial Doppler (TCD) was performed in 11 patients undergoing TEVAR. Wire and catheter placement in the arch was performed by two experienced operators...

OBJECTIVE/BACKGROUND: Matrix metalloproteinases (MMPs) have already been identified as key players in the pathogenesis of abdominal aortic aneurysm (AAA). However, the current data remain inconclusive. In this study, the expression of MMPs at mRNA and protein levels were investigated in relation to the degradation of collagen I and collagen III. METHODS: Tissue samples were obtained from 40 patients with AAA undergoing open aortic repair, and from five healthy controls during kidney transplantation...

Tetralogy of Fallot (TOF) is the most frequently diagnosed congenital cyanotic heart disease. It is often associated with additional findings, such as atrial septal defect (i.e., pentalogy of Fallot) or right sided aortic arch. Association of this pentalogy of Fallot with situs inversus totalis is rarely reported in paediatric literature and it can cause technical challenges to intracardiac repair. We report the case of pentalogy of Fallot with dextrocardia and situs inversus presenting as parieto-occipital abscess in a 12-year-old child...

Heart failure is a growing epidemic in the United States and throughout the world. The utilization of continuous-flow left ventricular assist devices (LVADs) has greatly increased over the last decade. In addition, a limited supply of organ donors has led to a rise in the use, and duration, of LVADs for destination therapy. The increased use of LVAD therapy has led to the observation of mechanical complications such as device thrombosis, de novo aortic insufficiency, and outflow graft stenosis, all of which are associated with prolonged LVAD support...

INTRODUCTION: Bilateral common iliac artery (CIA) aneurysm (CIAA) is a rare entity. In the past decade, different endovascular approaches have been adopted for patients with several comorbidities or unfit for open repair (OR). Recently, the use of iliac branch stent graft has been proposed, resulting in satisfactory patency rates and decrease in morbidity. Currently, according to instruction for use, the iliac branch stent graft is to be used with aortobi-iliac stent graft conjunction...

PURPOSE: To report the outcomes of fenestrated endovascular aneurysm repair (FEVAR) and compare early and midterm results in relation to stent-graft complexity. METHODS: Between August 2006 and December 2014, 141 consecutive patients (mean age 72±7.6 years, range 50-89; 120 men) were treated electively with FEVAR for short-neck, juxtarenal, or suprarenal aortic aneurysms. Forty-five patients treated with stent-grafts featuring renal-only fenestrations were assigned to group A, while 96 patients receiving additional fenestrations for the superior mesenteric and/or celiac arteries were assigned to group B...

W Randolph Chitwood
Localized ventricular septal hypertrophy, also known as idiopathic hypertrophic subaortic stenosis or idiopathic hypertrophic subaortic septal obstruction (IHSS), can create severe ventricular outflow obstruction. This often results in a high sub-aortic pressure gradient with potentially lethal symptoms. In 1960, Braunwald described the hemodynamic characteristics of IHSS, and thereafter, Morrow developed a trans-aortic approach to resect a large part of the ventricular septum, enlarging the outflow tract. The Morrow operation has remained the gold standard for surgically treating this pathology...

BACKGROUND: Robotic mitral valve (MV) repair is the least invasive surgical approach to the MV and provides unparalleled access to the valve. We sought to assess technical aspects and clinical outcomes of robotic MV repair for isolated posterior leaflet prolapse by examining the first 623 such cases performed in a tertiary care center. METHODS: We reviewed the first 623 patients (mean age 56±9.7 years) with isolated posterior leaflet prolapse who underwent robotic primary MV repair from 01/2006 to 11/2013...

BACKGROUND: The surgical treatment of Crawford extent II aneurysms after thoracic endovascular aortic repair (TEVAR) remains challenging, because of the need to remove the failed endograft and the complexity of the aortic reconstruction. We retrospectively reviewed our experience with surgical management of Crawford extent II aneurysms after TEVAR using thoracoabdominal aortic replacement (TAAR). METHODS: Eleven patients (10 males, 1 female) with Crawford extent II aneurysm after TEVAR were treated with TAAR between August 2012 and May 2015...

Behçet's disease (BD) is an autoimmune disorder affecting multiple organs. Aortic pseudoaneurysm is the most catastrophic lesion in BD. This lesion type is considered as a complicated and challenging pathology by surgeons because of the technical operative difficulties and frequent recurrence. So, the endovascular repair of inflammatory aortic pseudoaneurysm has been used as an alternative to open surgical repair. It is particularly important in patients who are high-risk surgical candidates because of comorbidities...

INTRODUCTION: Understanding the relationship between patient risk factors, postoperative complications, and morbidity and mortality is important when considering elective endovascular aortic aneurysm repair (E-EVAR) performed to prevent aneurysm rupture mortality. We aimed to stratify complications in E-EVAR and explore their relationship with postoperative death. METHODS: E-EVAR cases from 2012 NSQIP were identified. 30-day complications were categorized as major (MAJCX) or minor (MINCX) using the Clavien-Dindo classification...

BACKGROUND: Increasing numbers of older patients are undergoing vascular surgery. Inadequate preoperative assessment and optimization may contribute to increased postoperative morbidity and mortality. METHODS: Patients aged at least 65 years scheduled for elective aortic aneurysm repair or lower-limb arterial surgery were enrolled in an RCT of standard preoperative assessment or preoperative comprehensive geriatric assessment and optimization. Randomization was stratified by sex and surgical site (aorta/lower limb)...

BACKGROUND: Aortic aneurysm (AA) is one of the most common causes of sudden death among elderly people. Although AA can be detected by non-invasive imaging techniques, there are no pharmacological treatments currently available to prevent progression at any stage of the disease. In this study we will explore the expression of IKKε in AA and its potential underlying molecular mechanism in AA. Material s and methods: Human aortic tissue was taken from 14 patients who underwent surgical repair of AA for the AA group and another 11 patients with normal aorta who underwent aortic valve replacement surgery for the control group...

Blood transfusions have still been used as a standard therapy to treat severe anemia. Current evidences point to both excessive allogeneic blood consumption and decreased donations, which result in reduced stocks in blood banks. Several studies have increasingly suggested a more restrictive transfusion practice for blood products. Currently, a number of autologous blood conservation protocols in surgeries have been noted. We report a case of severe anemia with 2.9 g/dL hemoglobin, which was successfully handled without using the standard therapy to treat anemia with hemotransfusions...

Formation of an abdominal aortic aneurysm is a complex process involving aortic wall degradation. The matrix metalloproteinases (MMPs) mainly involved in this process are MMP-2 and MMP-9. Most aneurysms contain an intraluminal thrombus. It is suggested that the thrombus' thickness correlates with the risk of aneurysm rupture and may be a new prognostic factor. The purpose of the present study was to investigate enzyme protein levels in thick (A1) and thin (B1) segments of the thrombus and aneurysm wall sections A (adjacent to A1) and B (adjacent to B1)...
