BACKGROUND: Children with coarctation of the aorta (CoA) can have a hyperdynamic and remodeled left ventricle (LV) from increased afterload. Literature from an experimental model suggests the putative 20 mm Hg blood pressure gradient (BPG) treatment guideline frequently implemented in CoA studies may permit irreversible vascular changes. LV remodeling from pressure overload has been studied, but data are limited following correction and using a clinically representative BPG. MATERIALS AND METHODS: Rabbits underwent CoA at 10 weeks to induce a 20 mm Hg BPG using permanent or dissolvable suture thereby replicating untreated and corrected CoA, respectively...

OBJECTIVES: The aim of our prospective randomized study was to compare modified reverse aortoplasty (MRA) and extended end-to-end anastomosis (EEA). METHODS: We have assessed the operative correction results in 54 infants with coarctation of the aorta and distal aortic arch hypoplasia who underwent primary repair in our institute between July 2013 and February 2014. All of the patients were <12 months old when they had the operation. Patients were randomly assigned to 2 arms: modified reverse subclavian flap angioplasty (MRA group; n  = 27) or extended end-to-end anastomosis (EEA group; n  = 27)...

Atypical aortic coarctation (AAC) has been reported to occur anywhere along the aorta, except for the ascending aorta. The associated symptoms include hypotension in the lower half of the body, secondary hypertension in the upper half of the body, and heart failure. Here we present an 80-year-old Asian woman complaining of progressive exertional dyspnea. She was diagnosed with acute decompensated heart failure and kidney injury due to severely calcified stenosis of the thoracoabdominal aorta, the so called AAC...

OBJECTIVE: Women with repaired coarctation of the aorta (rCoA) are at risk of hypertensive disorders and other complications during pregnancy. Hypertensive disorders in pregnant women are associated with inadequate uteroplacental flow, which is related to adverse offspring outcome. The aim of this study was to investigate the relationship of maternal cardiac function, placental function and pregnancy complications in women with rCoA. METHODS: We included 49 pregnant women with rCoA and 69 controls from the prospective ZAHARA-studies (Zwangerschap bij Aangeboren HARtAfwijkingen, pregnancy in congenital heart disease)...

Severe ascending aorta disease includes aneurysms, pseudoaneurysms (ascending aorta pseudoaneurysms), penetrating aortic ulcers and Type A aortic dissections. Surgical replacement of the aortic root, ascending aorta or aortic arch is the common treatment for severe ascending aortic disease involving the root, the ascending aorta and/or the arch. Despite good surgical results, there is still a risk for morbidity and mortality following surgery for ascending aorta replacement when elderly patients or patients at high risk for surgery are concerned...

Bicuspid aortic valve (BAV) is the most common type of congenital heart defect (CHD) and is associated with clinically significant cardiovascular complications including valve calcification and ascending aortopathy (AscAo), predominantly occurring in adulthood. While a limited number of genetic etiologies for BAV have been defined, family members of affected individuals display BAV along with other left-sided CHD. This has led to guidelines from the American Heart Association and American College of Cardiology that recommend echocardiographic screening of first-degree relatives of affected adults...

BACKGROUND: Aortic coarctation (AC) is most commonly identified in pediatric patients; however, adults can present with late sequelae of untreated coarctation or complications of prior open repair. To date, there are limited data about the role of thoracic endovascular aortic repair (TEVAR) in this group of patients. The purpose of this analysis was to describe our experience with management of adult coarctation patients using TEVAR. METHODS: All TEVAR patients treated for primary coarctation or late sequelae of previous open repair (eg, pseudoaneurysm, recurrent coarctation or anastomotic stenosis related to index open coarctation repair) were reviewed...

BACKGROUND: Coarctation of the aorta (CoA) with aortic arch hypoplasia (AAH) is a relatively common congenital heart disease in clinical practice. Nonetheless, the corrective surgical technique for infants and children is a clinical problem that remains controversial. In this study, we sought to evaluate the surgical effects of aortic arch (AA) reconstruction with coarctation resection and aortoplasty with autologous pulmonary artery patch for infants and young children with CoA and AAH...

We present the case of a female adult with complex cyanotic congenital heart disease who had long-standing thoracic aortic obstruction due to scarring from earlier surgical procedures. She was symptomatic but felt to be too high risk for surgical intervention. With careful planning, she was able to undergo successful stenting of her aorta with subsequent clinical improvement. This case highlights some of the complexities of caring for adults with congenital heart disease and the importance of a thorough understanding of their anatomy and physiology and prior interventions before undertaking interventions...

Giant aortic aneurysm is defined as an aneurysm of the aorta of greater than 10 cm in diameter. This rare condition is associated with a high risk of morbidity and mortality and it may lead to fatal complications such as rupture and/or dissection if not managed with proper surgical planning and expertise. Other than atherosclerosis, the main causes of giant ascending aortic aneurysms include Marfan and Ehlers-Danhlos syndromes. Herein we report on a young male patient who had had an aortic valve replacement five years earlier due to a bicuspid aortic valve leading to aortic failure, accompanied by aortic coarctation...

The prevalence of congenital heart defects (CHD) in Kabuki syndrome ranges from 28% to 80%. Between January 2012 and December 2015, 28 patients had a molecularly proven diagnosis of Kabuki syndrome. Pathogenic variants in KMT2D (MLL2) were detected in 27 patients, and in KDM6A gene in one. CHD was diagnosed in 19/27 (70%) patients with KMT2D (MLL2) variant, while the single patient with KDM6A change had a normal heart. The anatomic types among patients with CHD included aortic coarctation (4/19 = 21%) alone or associated with an additional CHD, bicuspid aortic valve (4/19 = 21%) alone or associated with an additional CHD, perimembranous subaortic ventricular septal defect (3/19 = 16%), atrial septal defect ostium secundum type (3/19 = 16%), conotruncal heart defects (3/19 = 16%)...

A double-outlet left ventricle (DOLV) is a rare congenital cardiac malformation. Here, we describe a case of DOLV with bicuspid pulmonary valve, aortic coarctation, and a subpulmonary ventricular septal defect in which both ventricles were well developed. The anatomic features were observed with echocardiography, and the diagnosis was confirmed at surgery. Many variations of DOLV have been described. The features of our case expand the spectrum of this entity and may provide new insight into its complex anatomy...

Coarctation of the aorta is a condition that typically presents in childhood as a congenital malformation. This report describes a case of acute right middle cerebral artery ischemic stroke, which occurred in a patient with aortic coarctation that remained undiagnosed until her eighth decade. Complex anatomical variant presented a significant technical challenge in establishing endovascular access for mechanical thrombectomy using standard femoral, brachial, or radial artery approaches. Direct right common carotid puncture was performed successfully with subsequent reperfusion and full neurological recovery...

Intercostal artery aneurysms (ICAA) are very rare vascular complication of coarctation. The most cases are asymptomatic and could be found incidentally during thoracotomy for others vascular pathology or may present with fatal problems such as rupture that is leading to bleeding and hypovolemic shock. Intercostal artery aneurysm most commonly accompanies with neurofibromatosis, aortic coarctation, or in chest trauma. We report a 10-year-old girl who complained of lower extremities pain and hypertension for a few months...

OBJECTIVES: We sought to develop a hemodynamic model of aortic and ductal arches using computational fluid dynamics (CFD) and 3D/4D spatio-temporal image correlation (STIC) fetal echocardiography and to investigate the hemodynamics of coarctation of aorta (CoA) in human fetuses using this approach. METHODS: We obtained 3D/4D STIC fetal echocardiographic images of the aortic and ductal arches (DA) in five normal fetuses. Based on these images, we simulated the hemodynamics in the two arches using CFD...
