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...

BACKGROUND: We evaluated selected birth defects over a 9-year period to assess prevalence trends by selected maternal and infant factors. METHODS: Data were pooled from 11 population-based birth defects surveillance programs in the United States for children born between 1999 and 2007. Overall prevalence, as well as 3-year interval prevalence, was calculated for 26 specific birth defects, stratified by maternal age, maternal race/ethnicity, and infant sex. Average annual percent change (AAPC) was calculated for each birth defect...

BACKGROUND: We sought to compare clinical outcomes and resource utilization for two surgical approaches for single-stage repair of coarctation of the aorta and ventricular septal defect (VSD). METHODS: This was a retrospective chart review of 21 consecutive neonates and infants undergoing single-stage repair of coarctation of the aorta and VSD. Group 1 included 13 patients with both arch repair and VSD repair completed via sternotomy. Group 2 included eight patients with off-pump arch repair via left thoracotomy followed by repositioning and VSD repair via sternotomy...

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...

Once considered a childhood disease, the number of adults living with congenital heart disease (CHD) has now exceeded the number of pediatric patients. The landscape of percutaneous intervention for adult congenital heart disease (ACHD) has evolved over the past decade and has yet to be characterized in Canada. The aim of this study was to begin to understand the current infrastructure underlying ACHD interventions in Canada and to characterize the type and number of interventions being carried out across the country...

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...

M Komiyama
A novel hypothesis proposes that "cardio-cephalic neural crest (NC) syndrome," i.e. cephalic NC including cardiac NC, contributes to the concurrent occurrence of vascular diseases in the cardio- and cerebrovascular regions. NC is a transient structure present in early embryogenesis. Cephalic NC provides mesenchymal cells to the vascular media in these regions. Concurrent cardio- and cerebrovascular lesions have been reported in PHACE syndrome, ACTA2 mutation syndrome, and less frequently in the spontaneous occlusion of the circle of Willis (so-called moyamoya disease)...
