BACKGROUND: Left-sided cardiac obstructions represent 15% of congenital heart disease (CHD). The treatment in adults is surgical; however, balloon dilation by interventional catheterization can alleviate the symptoms in pediatric patients to allow them to reach the target height. The aim was to determine the survival and the factors associated with reintervention in patients with CHD with left-sided obstruction treated with balloon angioplasty. METHODS: A cohort study was conducted in patients aged 4 to 17 years with left-sided heart obstruction (valvular stenosis [VS], supravalvular aortic stenosis [SAS], coarctation of the aorta [CA]) successfully treated with balloon angioplasty...

Isolated Unilateral hypoplasia or agenesis of a branch of pulmonary artery is very rare. It is usually seen associated with congenital heart diseases such as tetralogy of Fallot, atrial septal defect, coarctation of the aorta, right aortic arch, truncus arteriosus, patent ductus arteriosus and pulmonary atresia. It occurs as a result of lack of embryological development of either the left or right sixth aortic arch and has been found to present itself with various clinical manifestations as during childhood it presents as contralateral pulmonary hypertension and in adults as haemoptysis...

Calcified atheromatous aortic lesion causing significant narrowing of the aorta is an uncommon clinical entity. This calcified atheroma leads to obstruction of the lumen of the aorta simulating acquired coarctation of aorta causing impaired perfusion of lower limbs, visceral ischemia, and hypertension. We report a case of 58-year-old patient who presented with dyspnea on exertion, orthopnea, paroxysmal nocturnal dyspnea, 25-lb weight gain, lower extremity edema, and chest pain. Extensive workup including computed tomography and magnetic resonance imaging revealed a large calcific mass in the aortic arch causing his presenting symptoms...

We describe a 54-year-old male with history of type II DM, hypertension and dyslipidemia during admission for bronchopneumonia discovered to have coarctation of the aorta and a persistent left superior vena cava (PLSVC) draining into the left atrium through the left superior pulmonary vein. The latter was thought to contribute to a transient ischemic attack and an episode of chest pain resulting in ST-segment elevation in the inferior leads. He was treated with coarctation stenting and percutaneous exclusion of the PLSVC with a vascular plug...

Coarctation of aorta (CoA) is a critical congenital heart defect (CCHD) that requires accurate and immediate diagnosis and treatment. Current newborn screening methods to detect CoA lack both in sensitivity and specificity, and when suspected in a newborn, it must be confirmed using specialized imaging and expert diagnosis, both of which are usually unavailable at tertiary birthing centers. We explore the feasibility of applying machine learning methods to reliably determine the presence of this difficult-to-diagnose cardiac abnormality from ultrasound image data...

Coarctation of the aorta is a congenital cardiac defect that results in a variable degree of obstruction to the left side of the heart. It can present with either acute shock in the neonatal period as a critical lesion or it can appear more insidiously with hypertension or other findings later in life. This article summarises aspects of outpatient care of patients with this lesion, including clinical history and physical examination, ancillary testing, and issues associated with long-term follow-up and management...

: Aim Echocardiography is the modality of choice for the diagnosis and serial follow-up of aortic arch pathology. In this article, we review the types of obstruction of the aortic arch, various classification schemes of coarctation of the aorta and interrupted aortic arch, methodology for optimal echocardiographic imaging of the aortic arch, and key echocardiographic measurements for accurate diagnosis of obstruction and hypoplasia of the aortic arch. Finally, we will discuss the limitations of echocardiography in optimal imaging of the aortic arch and the use of other non-invasive imaging modalities such as CT or MRI to provide additional information in these cases...

Patients with repaired coarctation of the aorta are thought to have increased afterload due to abnormalities in vessel structure and function. We have developed a novel cardiovascular magnetic resonance protocol that allows assessment of central hemodynamics, including central aortic systolic blood pressure, resistance, total arterial compliance, pulse wave velocity, and wave reflections. The main study aims were to (1) characterize group differences in central aortic systolic blood pressure and peripheral systolic blood pressure, (2) comprehensively evaluate afterload (including wave reflections) in the 2 groups, and (3) identify possible biomarkers among covariates associated with elevated left ventricular mass (LVM)...

A 57-year-old female presenting with acute-onset paraplegia was referred for magnetic resonance imaging (MRI) of cervico-dorsal spine. On MRI, multiple tortuous dilated vessels were noted in the epidural space with long segment cord compression and imaging features of compressive myelopathy. Associated small acute cervico-dorsal epidural hematoma was also noted in the same region. Computed tomography (CT) angiography was performed subsequently which revealed post-ductal coarctation of aorta with multiple arterial collaterals in the chest wall and spinal canal...

BACKGROUND: In the patients with longer-segment aortic arch hypoplasia or interruption with ventricular septal defect, surgery with homograft vessel or autologous pericardial patch to augment descending aortic arch will not result in adverse reactions caused by end-to-end anastomosis. In this study, we retrospectively analyzed primary experience of surgical correction of complicated aortic arch anomaly with autologous main pulmonary artery. METHODS: From July 2010 to March 2016, the twenty-one cases of aortic arch complex anomalies were reconstructed with autologous main pulmonary artery...

A 56-year-old female patient was transferred due to the presence of a left supraclavicular pulsatile mass. Further work-up was performed to confirm diagnosis. Angiography and computed tomography were also performed. The anatomy of the thoracic aorta suggested an unknown and untreated aortic coarctation. A second aortic narrowing was identified at the aortic arch, a result of elongation of the aorta. Endovascular approach was not possible, due to complexity of the aortic anatomy, and tortuosity. Open surgical repair was successfully performed...

AIMS: Models of blood flow in the left ventricle (LV) and aorta are an important tool for analysing the interplay between LV deformation and flow patterns. Typically, image-based kinematic models describing endocardial motion are used as an input to blood flow simulations. While such models are suitable for analysing the hemodynamic status quo, they are limited in predicting the response to interventions that alter afterload conditions. Mechano-fluidic models using biophysically detailed electromechanical (EM) models have the potential to overcome this limitation, but are more costly to build and compute...

OBJECTIVES: Coarctation of the aorta (CoA) in adolescents and adults is often complicated by other cardiac or aortic problems and may carry additional surgical difficulties. Limited studies have reported the surgical outcomes of CoA repair in this particular patient population. We reviewed our contemporary experience of open surgical management of CoA in adolescents and adults. METHODS: From 2008 to 2016, a total of 60 adolescents and adults (mean age, 32 years) underwent CoA repair at our centre...
