EDITORIAL
Dhaval R Parekh, Zvonimir Krajcer
Recurrent coarctation postoperative Norwood is poorly tolerated in single ventricle patients. Although transcatheter balloon angioplasty is considered first line, it often leads to inadequate or non-durable relief of obstruction. Transcatheter stent implantation provides excellent relief of obstruction but necessitates staged redilation to account for somatic growth in children. Stent technology, delivery systems, and procedural techniques will need to evolve to obviate reported adverse events mainly due to patient size...

BACKGROUND: Children with major congenital heart defects are risking impaired cerebral growth, delayed cerebral maturation, and neurodevelopmental disorders. We aimed to compare the cerebral tissue oxygenation of fetuses with major heart defects to that of fetuses without heart defects as estimated by the magnetic resonance imaging modality T2*. T2* is low in areas with high concentrations of deoxyhemoglobin. METHODS AND RESULTS: At gestational age mean 32 weeks (early) and mean 37 weeks (late), we compared the fetal cerebral T2* in 28 fetuses without heart defects to that of 15 fetuses with major heart defects: transposition of the great arteries (n=7), coarctation of the aorta/hypoplastic aortic arch (n=5), tetralogy of Fallot (n=1), hypoplastic right heart (n=1), and common arterial trunk (n=1)...

BACKGROUND: Numerous studies indicate that statins have also multiple beneficial actions (known as 'pleiotropic actions') on cardiovascular system through the improvement of endothelial dysfunction, inflammation, oxidative stress, increased arterial thrombosis, and the stabilization of the atherosclerotic plaque. Aortic disease primarily consists of aortic valve stenosis, aortic valve regurgitation, aneurysm disease, and genetic disorders such as Marfan syndrome, bicuspid aortic valve and aortic coarctation...

Coarctation of the Aorta is a congenital narrowing of the aorta. Two commonly used treatments are resection and end-to-end anastomosis, and stent placements. We simulate blood flow through one-dimensional models of aortas. Different artery stiffnesses, due to treatments, are included in our model, and used to compare blood flow properties in the treated aortas. We expand our previously published model to include the natural tapering of aortas. We look at change in aorta wall radius, blood pressure and blood flow velocity, and find that, of the two treatments, the resection and end-to-end anastomosis treatment more closely matches healthy aortas...

An infant with coarctation of the aorta and Williams syndrome was noted to have petechiae in cardiology clinic prior to planned surgical intervention. Workup revealed acquired von Willebrand syndrome secondary to the high shear force generated by the aortic coarctation. He was treated with intra- and postoperative Humate P; there were no postoperative bleeding complications. His acquired von Willebrand syndrome resolved postoperatively.

Most patients with hypertension have no clear etiology and are classified as having primary hypertension. However, 5% to 10% of these patients may have secondary hypertension, which indicates an underlying and potentially reversible cause. The prevalence and potential etiologies of secondary hypertension vary by age. The most common causes in children are renal parenchymal disease and coarctation of the aorta. In adults 65 years and older, atherosclerotic renal artery stenosis, renal failure, and hypothyroidism are common causes...

In this article, we report on a newborn with hypoplastic left heart syndrome in whom recoarctation of the aorta was treated with a bare metal stent (Cook Formula 414 Stent) in the early postoperative period after a Norwood procedure. To reduce the risk for scarring and occluding the femoral artery the stent was implanted via 5F Glidesheath Slender sheath.

One of the most important problems in patients with aortic coarctation after aortic arch repair is future cardiovascular disease. We have previously reported that the enhancement of aortic pressure wave reflection in patients could be one of the causes of future cardiovascular diseases, because it results in an increase of the left ventricular workload and is disadvantageous for coronary circulation. Seventeen patients who had undergone aortic arch repair without pressure gradient in their aortic arch were enrolled...

OBJECTIVES: Late hypertension after coarctation repair is associated with high mortality, but its risk factors remain unclear. This study aims to determine early and late postoperative risk factors for late hypertension after coarctation repair. METHODS: A cross-sectional study including transthoracic echocardiogram and 24-h blood pressure (BP) monitoring was performed in 144 patients aged ≥10 years with previous coarctation repair. Median age at repair was 39 days (interquartile range 0-3 years)...

Stent placement is commonly used to treat aortic coarctation. Although invasive angiography remains the gold standard, follow-up is often performed using computed tomography, which allows rapid, noninvasive assessment of the aorta and surrounding tissues. The goal of this pictorial essay is to provide a guide to the interpretation of these examinations. Normal and abnormal computed tomographic appearance of different stent types is shown along with reconstructions that can help assess stent integrity and the stent position in relation to the aortic wall and branches...

The transposition of the great arteries (TGA) is a complex congenital heart disease which usually presents as cyanosis in neonates with limited mixing between the systemic and pulmonary circulatory systems. A delayed diagnosis of TGA can lead to ventricular failure. We report a six-week-old infant who was admitted to the paediatric Intensive Care Unit of the Royal Hospital, Muscat, Oman, in 2016 for bronchiolitis. During admission, she was incidentally diagnosed with TGA and coarctation of the aorta. Postnatal screening, including the use of pulse oximetry, plays a significant role in avoiding a late diagnosis of TGA; however, this screening tool is not widely used in Oman...

Children with acquired and congenital heart disease (CHD) are increasingly surviving to adulthood. Our aim was to determine the prevalence of coronary artery disease (CAD) risk factors in children at known risk for early CAD or with severe CHD. We recruited children (8-19 years) at risk for early CAD-Kawasaki disease (KD, N = 36) and coarctation (69) or severe CHD: > 1 cardiopulmonary bypass surgery (60), single ventricle (15), prosthetic valves (13). Anthropometric measurements, blood pressure, and fasting lipid data were compared with summaries from National Health and Nutrition Examination Survey (NHANES) publications (1999-2012)...

We herein report two cases of progressive left ventricular outflow obstruction after primary repair of arch obstruction and ventricular septal defect that was successfully resolved with Yasui conversion. Patients who require surgical reintervention for progressive left ventricular outflow tract (LVOT) obstruction after primary biventricular repair of interruption of the aortic arch or coarctation of the aorta complex are occasionally experienced. The modified Konno procedure and Ross operation are well recognized as useful for these cases...

Evidence indicates that patients with coarctation of the aorta (COA) suffer from increased cardiovascular morbidity and mortality in later life despite successful repair of COA in childhood. Systolic arterial hypertension is common, presenting in up to one-third of patients, and is regarded as the main driver of premature cardiovascular events in this group of patients. In this review, we discuss the prevalence and pathophysiology of hypertension in children following successful COA repair with no residual arch obstruction...
