BACKGROUND: Simulation is frequently used to recreate many of the crises encountered in patient care settings. Teams learn to manage these crises in an environment that maximizes their learning experiences and eliminates the potential for patient harm. By designing simulation scenarios that include conditions associated with diagnostic errors, teams can experience how their decisions can lead to errors. The purpose of this study was to assess how trauma teams (TrT) and pediatric rapid response teams (RRT) managed scenarios that included a diagnostic error...

BACKGROUND: One indication for intervention in coarctation of the aorta is a peak-to-peak gradient >20 mmHg. Gradients may be masked in patients under general anaesthesia and may be higher during exercise. Isoproterenol was given during cardiac catheterisation to simulate a more active physiologic state. OBJECTIVES: We aimed to describe the haemodynamic effects of isoproterenol in patients with coarctation and the impact of intervention on the elicited gradients...

Stent grafting for complex aortic anatomy remains a challenge. In particular, stent graft collapse (i.e. infolding) is possible when an excessive oversized device is needed. We describe a case of preoperative stent grafting simulation using a three-dimensional (3D) printed model for extensive aortic arch repair in a 69-year-old woman with multiple aneurysms combined with coarctation. The patient was scheduled to undergo staged hybrid repair. A stent graft larger than 28 mm in diameter was needed to deploy into a coarctation of 15 mm in diameter during the 2nd stage of the operation...

Coarctation of the aorta (CoA) is a congenital cardiac malformation that is well understood. Despite being well characterized, CoA is a commonly missed congenital heart disease (CHD) during the newborn period. We report a full-term nine-day-old male who presented to the pediatric emergency department (ED) with isolated tachypnea. After an initial sepsis workup, subsequent investigations revealed critical CoA. Because the primary workup focused on sepsis, there was a significant delay in prostaglandin E1 (PGE1 ) initiation...

BACKGROUND: Coarctation of the aorta (CoA) is one of the most common congenital heart defects. Due to improved surgical techniques, most patients live into adulthood. However, late complications including hypertension, recoarctation and arrhythmias are common. The autonomic nervous system (ANS) might play a role in the pathology. The aim of this study was to evaluate cardiac ANS activity and cardiac function in children after CoA repair and investigate the relationship between the two...

PURPOSE: To develop a rapid segmentation-free method to visualize and compute wall shear stress (WSS) throughout the aorta using 4D Flow MRI data. WSS is the drag force-per-area the vessel endothelium exerts on luminal blood; abnormal levels of WSS are associated with cardiovascular pathologies. Previous methods for computing WSS are bottlenecked by labor-intensive manual segmentation of vessel boundaries. A rapid automated segmentation-free method for computing WSS is presented. THEORY AND METHODS: Shear stress is the dot-product of the viscous stress tensor and the inward normal vector...

Spontaneous regression of severe aortic coarctation with ductus dependency has not been reported. We experienced a case of trisomy 18 with spontaneous regression of severe aortic coarctation complicated by ventricular septal defect and patent ductus arteriosus. The aortic isthmus diameter was 1.2 mm at birth. After 5 months, it increased to 4.5 mm, and the shape of the isthmus was fully normalised.

A 45 year-old-man who had undergone ventricular septal defect repair during childhood presented with hoarseness. He was diagnosed as having a distal aortic arch aneurysm by using computed tomography, and was referred to our hospital for surgical treatment. The operation was performed via a 4th intercostal thoracotomy in the right lateral position. The aortic aneurysm occupied the upper pleural cavity. The aortic arch was pressed up by the aortic aneurysm, so visual identification and clamping of the proximal aorta and the left subclavian artery were extremely difficult...

Endothelial cells (ECs) are located at the interface between flowing blood and the vessel wall, and abnormal EC proliferation induced by pathologic environments plays an important role in vascular remodeling in hypertensive conditions. Exchanges of information between blood components and ECs are important for EC function. Hence, the present study sought to determine how platelets induce EC dysfunction under hypertensive conditions. EC proliferation was increased in renal hypertensive rats established by abdominal aortic coarctation compared with control rats and that elevated thrombin in plasma promoted platelet activation, which may induce the release of platelet-derived microparticles (PMPs)...

OBJECTIVE AND METHODS: The use of conventional metal stents in infants is severely limited by subsequent somatic growth. The use of a breakable balloon expandable stent (BS) designed for initial implant at small diameters but with properties that allow unlimited dilation in line with growth has potential advantages in this patient group. This study reports our experience with this stent between 2010 and 2014. A total of 17 BS were implanted in 14 infants (mean age 4.8 months). All but one stent was placed into the aorta to treat coarctation...

AIM: To assess the acute results of the first human use of the Optimus covered stent in complex coarctation of the aorta. METHODS AND RESULTS: We successfully implanted the Optimus covered stent in eight cases in patients whose preprocedural anatomy looked challenging for currently available covered stents. Six of the patients had native coarctation with one recoarctation following surgical repair. There were no significant complications with reduction in the mean invasive gradient from 22 to 1 mm Hg...

Coarctation of the aorta is a congenital cardiac malformation that can go undiagnosed until old age with only hypertension as a marker of its presence because clinical signs can be subtle and overlooked if a complete physical exam is not performed. Long-term survival is exceptional in patients with untreated aortic coarctation. In this case report, we present a late diagnosis of aortic coarctation in a 45-year-old male. Our patient was relatively asymptomatic until he presented with exertional dyspnea and fatigue in his fourth decade of life in Bangabandhu Sheikh Mujib Medical University (BSMMU), on the month of August, 2016...

PURPOSE: Coarctation of the aorta (CoA) in adolescents and adults is relatively rare. Several operative techniques for CoA in adolescents and adults have been reported, but there is still no consensus. This study aims to highlight the use of individual patient characteristics to select optimal treatment strategies for CoA in adolescents and adults. METHODS: Surgical repair of CoA was performed in five patients (mean age: 34 ± 14 years, range: 13-58 years). All patients had primary CoA, and one had aneurysm above the CoA...

Children with single ventricle physiology have complete mixing of the pulmonary and systemic circulations, requiring staged procedures to achieve a separation of these circulations, or Fontan circulation. The single ventricle physiology significantly increases the risk of mortality in children undergoing non-cardiac surgery. As liver transplantation for patients with single ventricle physiology is particularly challenging, only a few reports have been published. We herein report a case of successful LDLTx for an 8-month-old pediatric patient with biliary atresia, heterotaxy, and complex heart disease of single ventricle physiology...

An 11-month-old girl with an unbalanced atrioventricular septal defect, coarctation of the aorta and an interrupted inferior vena cava with hemiazygos continuation post-surgical status of coarctation repair and pulmonary artery banding underwent a Kawashima operation. Severe hypoxia occurred immediately after she was weaned from cardiopulmonary bypass, which was successfully resolved by the ligation of the hemiazygos vein. Postoperative enhanced computed tomography detected significant venovenous malformation from the hemiazygos vein to the left renal vein...

Congenital aortic anomalies are uncommon causes of secondary hypertension and are seldom suspected in the adult age group. We present a case of aortic interruption unexpectedly diagnosed on autopsy in a 38-year-old male who presented with cardiovascular collapse. Apart from interruption, a finding unique to our case was aneurysmal dilation of the proximal descending aorta just before the obstruction with thrombosis. We also attempt to review the literature for interrupted aortic arch in adults and clarify the nomenclature of interruption versus coarctation...

Berry syndrome is a rare congenital cardiac malformation. We describe 4 cases of Berry syndrome diagnosed by fetal echocardiography. Based on our experience, the three-vessel view is important for diagnosing the aortopulmonary window and aortic origin of the right pulmonary artery. Furthermore, the true cross-sectional and sagittal views obtained by continuously scanning from the three-vessel-trachea view to the long-axis view of the aortic arch are required to image the interruption or coarctation of the aortic arch...

Interrupted aortic arch is a rare congenital anomaly in newborns and infants and is commonly associated with other cardiovascular anomalies. Here, we report an unusual case of type A interrupted cervical aortic arch associated with long segment coarctation of the descending thoracic aorta. Patent ductus arteriosus reconstituted the descending thoracic aorta. Proximal segments of the left common carotid and left subclavian arteries were atretic. Echocardiography-gated multidetector CT angiography not only identified the type of aortic arch interruption in the neonate but also delineated the exact anatomical details...
