Wall shear stress (WSS) disturbances are commonly expressed at sites of abnormal flow obstructions and may play an essential role in the pathogenesis of various vascular diseases. In laminar flows these disturbances have recently been assessed by the transverse wall shear stress (transWSS), which accounts for the WSS multidirectionality. Site-specific estimations of WSS disturbances in pulsatile transitional and turbulent type of flows are more challenging due to continuous and unpredictable changes in WSS behavior...

Coarctation of the aorta (CoA) is reported to be associated with an increased risk for migraine. We describe here the case of a 13-year-old female patient who presented migraine with aura after surgical repair of CoA with a stent. As possible reasons for her condition, we postulate host responses to stent placement and/or disturbed cerebral autoregulation related to intracranial hypertension before the surgical repair and hypotension afterward, leading to hypoperfusion. This case demonstrates that de novo migraine with aura can occur after surgical repair of CoA and should be recognized as a potential complication...

An 11-year-old boy presented with easy fatigability, multiple xanthomas, and absent pedal pulsations. Laboratory workup showed severe hypercholesterolaemia and non-invasive imaging revealed 'normally functioning' bicuspid aortic valve and tight aortic coarctation. Coronary angiography showed severe right coronary artery (RCA) stenosis. Medical treatment resulted in significant improvement of dyslipidaemia. We successfully performed balloon dilation and stenting of his coarctation, as well as percutaneous coronary intervention for RCA lesion...

Stent implantation using a Cheatham Platinum (CP) stent for coarctation of the aorta (CoA) is a promising treatment alternative to traditional surgical repair. However, there are no earlier reports in the literature focusing on use of this stent in a Taiwanese patient. Herein we report a 16-year-old boy with CoA presenting with heart murmur and exercise intolerance who underwent successful CP stent placement. However, severe hypertension with arterial blood pressure increasing to 207/104 mmHg occurred four hours after stent implantation...

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...

Coarctation of the aorta (CoA) is the most common ductal-dependent lesion missed on neonatal exam screening. Prenatal diagnosis of CoA improves outcomes through early initiation of prostaglandin. Fetal echocardiographic parameters including 2D and Doppler findings have been studied as predictive measures for fetal diagnosis of CoA, but diagnosis rates remain variable. A comprehensive set of predictor variables was applied to fetuses suspected of CoA to analyze which parameters were associated with postnatal CoA...

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...

Transposition of the great arteries occurs rarely in patients with mirror image dextrocardia and situs inversus, while the combination with severe coarctation of the descending aorta (CoA) makes the anatomy even more unusual. Therefore, it is not surprising that a case with such unusual and complicated anatomy presents unique problems when a primary definitive correction is attempted. We report a patient with situs inversus totalis and complex congenital heart disease including transposition of the great arteries and severe CoA who underwent successful complete, single-stage, anatomic correction...

PURPOSE: Umbilical cord hernia is poorly understood and often miscategorized as "omphalocele minor". Careless clamping of the cord leads to iatrogenic gut injury in the situation of umbilical cord hernia. This study aimed to determine the characteristics and outcomes of umbilical cord hernias. We also highlight an alternative repair method for umbilical cord hernias. METHODS: We recorded 15 cases of umbilical cord hernias over 10 years. The patients' data were retrospectively reviewed, and preoperative preparation of the newborn, gestational age, birth weight, other associated malformations, surgical technique used, enteral nutrition, and length of hospitalization were recorded...

BACKGROUND AND AIMS: Patients with coarctation of the aorta (CoA) have increased left ventricular (LV) afterload that has been shown to impact the LV and ascending aortic function. We aimed to examine the effect of coarctation on LV function and aorto-septal angle (AoSA) before and after surgical repair. METHODS: We retrospectively studied 21 patients with surgically repaired CoA at a median age of 9 (2-53) days at three time points: (1) just before intervention, (2) at short-term follow-up, and (3) at medium-term follow-up after intervention...

BACKGROUND: Infantile hemangioma (IH) with minimal or arrested growth (IH-MAG) is becoming increasingly recognized in the literature. It is important to be aware of their existence, because the correct diagnosis is essential for prognostication and treatment and, in the case of facial segmental lesions, the direction of further investigations if PHACE (posterior fossa abnormalities and other structural brain abnormalities; hemangioma(s) of the cervical facial region; arterial cerebrovascular anomalies; cardiac defects, aortic coarctation, and other aortic abnormalities; eye anomalies) syndrome or Sturge-Weber syndrome is suspected...

OBJECTIVE: Long-term sequelae and events after coarctation repair are well described. However, the predictive value of variables from clinical follow-up investigation for late events and survival has rarely been investigated. METHODS: All patients who participated in the prospective cross-sectional COALA Study in 2000 with a structural clinical investigation including blood pressure measurement and symptom-limited exercise test were contacted for reevaluation of survival, current clinical status and major cardiovascular events...

Congenital variants and anomalies of the aortic arch are important to recognize as they may be associated with vascular rings, congenital heart disease, and chromosomal abnormalities, and can have important implications for prognosis and management. The purpose of this article is to review cross-sectional imaging techniques used in the evaluation of the aortic arch, describe the embryology and anatomy of the aortic arch system, discuss aortic arch variants and anomalies, and review other malformations of the aortic arch, including interrupted aortic arch, hypoplastic aortic arch, and aortic coarctation...

OBJECTIVE: To assess medium-term effects of treatment for mild to moderate recoarctation in an adult population. DESIGN: We identified all patients who had coarctation repair between 1965 and 1985 in our institution. They were all (n = 156) invited to a thorough outpatient examination, which was accepted by 133. Eleven (median age 36 [28-53] years) were identified with isolated mild to moderate recoarctation and received reintervention. They comprise the patient population of the current study...

We present a case of 13-year-old female with Turner syndrome (TS), who presented with unexplained lower limbs swelling and ejection systolic murmur at the left second intercostal space. Suspicion of mild aortic coarctation was made by echocardiography. Computed tomography angiography (CTA) showed a complete interruption of the aortic arch (IAA) below the left subclavian artery with persistent left superior vena cava (PLSVC) and absent right SVC, defined as an isolated PLSVC. The patient underwent successful surgical correction after unsuccessful trial of transcatheter stent placement...

BACKGROUND: Left ventricular outflow tract obstruction (LVOTO) is a common complication following surgical repair of atrioventricular septal defect (AVSD). OBJECTIVE: We sought to determine predictors of LVOTO based on echocardiograms performed prior to initial repair of AVSD. METHODS: Of the 415 children that had repair of AVSD from 2003 to 2012, 17 children were identified with LVOTO that required surgical intervention. Thirty-four patients with repaired AVSD and no LVOTO served as controls...

In infants with a single right ventricle (RV), stage I palliation involves aortic reconstruction, systemic-to-pulmonary shunt placement, and atrial septectomy. Many require re-intervention for residual coarctation of the aorta (CoA). Doppler echocardiography can detect residual CoA in most infants, but its ability to predict severity has not been studied. This study compares gradients from Doppler interrogation to those from cardiac catheterization in infants with residual CoA. We performed a retrospective study of infants after stage I palliation from 2000 to 2014...

OBJECTIVE: Screening for critical congenital heart disease (CCHD) using pulse oximetry has been endorsed by the American Academy of Pediatrics and the American Heart Association. The recommended screening requires two saturation readings. We sought to determine the incidence of undetected CCHD in Tennessee for the 2 years following implementation of an algorithm that assigned an immediate pass to a single lower extremity saturation of 97% or higher. STUDY DESIGN: State Genetic Screening records and reports of missed cases from the Tennessee Initiative for Perinatal Quality Care were used to determine if CCHD cases were missed by the new screening algorithm...
