INTRODUCTION: Cornelia de Lange syndrome (CdLS) is produced by mutations in genes that encode regulatory or structural proteins of the cohesin complex. Congenital heart disease (CHD) is not a major criterion of the disease, but it affects many individuals. The objective of this study was to study the incidence and type of CHD in patients with CdLS. MATERIAL AND METHOD: Cardiological findings were evaluated in 149 patients with CdLS and their possible relationship with clinical and genetic variables...

INTRODUCTION AND OBJECTIVES: Dilatation of the ascending aorta associated with bicuspid aortic valve is a major cause of morbidity and mortality in adults. The main objective was to recognize the aortic involvement in children, its characteristics and risk factors. METHODS: Aortic measures of all pediatric patients with bicuspid aortic valve followed in a tertiary pediatric hospital between 1997 and 2015 were retrospectively taken. Patients with syndromes associated with aortic dilatation were excluded (n=17)...

PURPOSE OF REVIEW: To provide an overview of current recommendations and techniques used to image coarctations of the aorta. RECENT FINDINGS: Imaging of coarctation of the aorta in adults is moving away from conventional techniques such as echocardiography and invasive angiography. Echocardiography may assist in making the diagnosis but is limited in its ability to quantify the severity of coarctations. Current guidelines recommend that every patient with a coarctation must undergo a computed tomography (CT) or MRI scan for accurate delineation of morphology...

Recurrent aortic arch obstruction (RAAO) remains a major cause of morbidity following surgical neonatal repair of coarctation of the aorta (CoA). Elucidating predictors of RAAO can identify high-risk patients and guide postoperative management. The Coarctation index (CoA-I), defined as the ratio of the diameter of the narrowest aortic arch segment to the diameter of the descending aorta, has been used to help diagnose RAAO in neonates following the Norwood Procedure. We sought to assess the predictive value of the CoA-I on RAAO after CoA repair in infants with biventricular circulation...

A 56-year hypertensive, multiparous woman presented to the cardiology unit with Canadian Cardiovascular Society (CCS) class-III angina and worsening dyspnea for the past few weeks. Her clinical examination showed high blood pressure and mid-systolic crescendo-decrescendo murmur radiating to carotids. However, there was no radio-femoral delay or significant blood pressure difference between her arms. Her transthoracic echocardiography (TTE) revealed moderate aortic stenosis (AS) and mid cavity left ventricular outflow (LVO) obstruction...

OBJECTIVES: Ventricular size disproportion is a marker for aortic coarctation (CoA) in fetal life, however, approximately 50% of fetuses do not develop CoA after birth. The aim of this study was to evaluate the postnatal outcome of cases with ventricular disproportion in the absence of CoA in this cohort. METHODS: All cases with prenatal isolated ventricular size disproportion in the period 2002-2015 were extracted from a prenatal congenital heart defects (CHD) registry of a regional cohort...

BACKGROUND: Hypertension following primary coarctation repair affects up to a third of subjects. A number of studies suggest that future hypertension risk is reduced if primary repair is performed at a younger age. OBJECTIVES: The objective of this study was to evaluate the risk of future medical treatment for hypertension depending on age of primary coarctation repair. METHODS: This study was carried out at a tertiary paediatric cardiology referral centre...

A 6-year-old boy (weight 15.5 kg) underwent pulmonary valve plasty using autologous pericardium. He received a diagnosis of aortic coarctation and ventricular septal defect. Total correction was performed at the age of 18 days ( weight 2.2 kg). Intraoperatively, to confirm the position of the ventricular septum defect, we needed to incise from the main pulmonary artery to right ventricle through a commissure part of pulmonary valve. Although he exhibited stable hemodynamics, pulmonary valve regurgitation progressed...

OBJECTIVES: To investigate survival and freedom from reintervention after aortic coarctation repair in Maltese patients and to compare cardiovascular mortality in coarctation repair survivors with that in the general population. DESIGN: All 72 aortic coarctation patients with any type of repair, born by end-1997 and logged in the local database were included. Trends in timing and type of repair were determined by comparing patients born before and after 1985. Kaplan-Meier analyses of survival and reintervention-free survival were performed on the 59 repair survivors with complete follow-up data (mean follow-up 26...

OBJECTIVES: To determine the early and late outcomes of patients undergoing aortic arch reoperations. METHODS: The follow-up of 70 patients undergoing a second arch operation (excluding univentricular physiology) between 1979 and 2015 was reviewed. Median age at initial arch operation and second operation was 9 days (interquartile range: 5-35) and 10 months (interquartile range: 3-64), respectively. The most common indication for initial arch operation was coarctation in 79% (55/70)...

We report stenting of coarctation of an angulated right circumflex aortic arch (RCAA) using four Cheatham Platinum stents in a child with Goldenhar syndrome. Difficulties in measuring the accurate length of the curved and narrowed transverse aortic arch marked discrepancy between the luminal diameters of the long narrow transverse arch and wide descending thoracic aorta, increased displacement force caused by the 90° bend between the two parts resulted in repeated stent migrations. We discuss the tips to avoid distal stent migration in the setting of an angulated RCAA...

BACKGROUND: Survival into adult life in patients with aortic coarctation is typical following surgical and catheter-based techniques to relieve obstruction. Late sequelae are recognised, including stroke, hypertension, and intracerebral aneurysm formation, with the underlying mechanisms being unclear. We hypothesised that patients with a history of aortic coarctation may have abnormalities of cerebral blood flow compared with controls. METHODS: Patients with a history of aortic coarctation underwent assessment of cerebral vascular function...

BACKGROUND: Despite successful repair in early life, patients with coarctation of the aorta (CoA) are predisposed to several cardiovascular complications in later life related to systemic hypertension or left ventricular (LV) dysfunction, or both, the pathogenesis of which is unclear. METHODS: Three-week-old Sprague-Dawley rats underwent transverse aortic constriction (TAC) or a sham operation, with release of the constriction 3 weeks later. Twenty-five weeks after the repair operation, animals underwent hemodynamic assessment, LV gene profiling, and histologic analysis...

PURPOSE: Postcoarctation thoracic aortic aneurysm formation is one of the most serious complications for coarctation of aorta. Open surgery to repair these aneurysms is associated with high morbidity and mortality. Endovascular therapy is an attractive alternative to open surgery. We have studied the efficacy and safety of endovascular therapy for postcoarctation thoracic aortic aneurysms, and will share our findings and experience through this document. METHODS: The data was retrospectively collected on consecutive patients who were presented with postcoarctation thoracic aortic aneurysms at our medical center...

Coarctation of aorta is a rare congenital malformation and is usually accompanied by other cardiac or vascular lesions. In this case we describe a 51-year-old patient presented with coarctation of the aortic arch and postcoarctation ectasia concomitant with a left subclavian artery aneurysm. Endovascular therapy included the deployment of an inverted wedge-shaped covered stent inserted by a long "chimney" stent and another cylinder-covered stent, forming a "sandwich"-like configuration. The symptoms were alleviated after surgery, and no perioperative or stent-graft-related complications were observed at a 2-year follow-up...

OBJECTIVES: We aimed to assess the results of various tailored management strategies for adults with coarctation in our centre. METHODS: : We reviewed all adults patients treated for aortic caorctation between January 2000 and December 2015 in our institution. The primary end point was a composite of death, perioperative stroke, paraplegia, need for unplanned reoperation or occurrence of pseudoaneurysm during the follow-up. The mean follow-up was 82 ± 5 months...
