BACKGROUND: Unicuspid aortic valve (UAV) is a rare disorder, often difficult to distinguish from bicuspid aortic valve (BAV). BAV and UAV share valve pathology such as the presence of a raphe, leaflet fusion, aortic stenosis, aortic regurgitation, and/or ascending aortic dilatation, but a comprehensive echocardiographic comparison of patients with UAV and BAV has not been previously performed. METHODS: We investigated UAV and BAV patients at an early stage of disease included in GenTAC, a national registry of genetically related aortic aneurysms and associated cardiac conditions...

OBJECTIVES: We sought to evaluate outcomes of stent implantation (SI) for recurrent coarctation of the aorta (RC) following the Norwood operation. BACKGROUND: RC is common following the Norwood operation. Balloon angioplasty (BA) is standard treatment but may result in unsatisfactory relief of RC. SI may improve RC, but outcome data are limited. METHODS: We performed a multi-center retrospective study of patients who underwent SI for RC between the Norwood operation and Fontan completion...

Taussig-Bing anomaly and aortic arch obstruction are two types of complex congenital cardiac malformations. Almost 50% of patients with Taussig-Bing anomaly have aortic arch obstruction. This report assesses the surgical outcomes of single-stage correction in neonates with both defects. Between November 2006 and November 2015, 39 neonates with Taussig-Bing anomaly and aortic arch obstruction (28 patients with coarctation of the aorta and 11 patients with interrupted aortic arch) underwent a one-stage arterial switch operation and aortic reconstruction...

PURPOSE: Endovascular treatment of coarctation of aorta (CoA) by self-expandable Nitinol stents is one of the recognized treatment methods and may be an alternative to surgery or balloon-expandable stent implantation for CoA but there is little information about midterm to long term results of self-expandable stents. METHODS: Sixty-two patients with CoA (40 men), with a mean age of 30.7 ± 11 years, (range 17-63 years) underwent stent implantation with Optimed self-expandable Nitinol stents between 2005 and 2014...

Pseudocoarctation is an unusual anomaly mirroring true coarctation. Congenital kinking or pseudocoarctation of aorta was never a benign condition. Although surgical repair should be suggested for all symptomatic individuals. Regular follow-up is obligatory for all asymptomatic patients deprived of linked anomalies. We suggest CT-aortogram as a non-invasive imaging modality for the definitive diagnosis of pseudocoarctation.

Qingwang Hua, Zhiyong Lin, Xingti Hu, Qifeng Zhao
Congenital abnormalities of the aortic arch include interrupted aortic arch (IAA), coarctation of the aorta (CoA), and double aortic arch (DAA). Aortic arch repair is difficult and postoperative complications are common. However, postoperative tracheobronchial stenosis with respiratory insufficiency is an uncommon complication and is usually caused by increased aortic anastomotic tension. We report here a case of tracheal compression by a mediastinal hematoma following IAA surgery. The patient underwent a repeat operation to remove the hematoma and was successfully weaned off the ventilator...

A 36-year-old female was admitted to hospital exhibiting chest pain, dyspnea, and a heart murmur on the right upper sternal border, radiating to both carotid arteries. The blood pressure of the patient's right arm exceeded the pressure in the left by 25 mm Hg (Coanda effect). In spite of laboratory results that did not fall outside the expected range, the left ventricle was revealed to be hypertrophic following electrocardiography. Transthoracic echocardiography revealed a severe supravalvular aortic stenosis (SVAS) with a peak Doppler velocity of 6...

BACKGROUND Coarctation of the aorta is characterized by narrowing of the descending aorta. The narrowing typically is at the isthmus, the segment just distal to the left subclavian artery. Adults with undiagnosed aortic coarctation are asymptomatic or may present with nonspecific hypertension. We present a case that highlights the uncommon complication of aortic coarctation with spinal compression syndrome. CASE REPORT A 45-year-old male presented to the emergency department (ED) with acute-onset chest pain; he experienced urinary incontinence and bilateral lower limb weakness during his ED visit...

Anomalous origin of the left coronary artery from the right pulmonary artery in single ventricles is a very rare congenital anomaly. Failure to recognise it preoperatively may lead to adverse outcomes, including death. We report the case of a neonate with a univentricular heart in the form of a double-outlet right ventricle, mitral atresia with discrete coarctation of the aorta, and an incidental intraoperative finding of an anomalous origin of the left coronary artery from the right pulmonary artery. The patient underwent a successful repair with an uneventful postoperative course...

Coarctation of the aorta is an uncommon cause of treatment-resistant hypertension in adults. It is typically detected and treated in infancy or childhood with surgical or endovascular procedures. Most cases of recurrence of coarctation after repair occur in childhood or early adulthood; recurrence in older persons (>70 years) has rarely been reported. A 73-year-old woman was referred to us for the management of treatment-resistant hypertension accompanied by symptoms of claudication and headaches, which had resulted in multiple emergency room visits...

There has been tremendous growth in the population of adults with congenital heart disease (CHD) over the last few decades because of advances in medical care. Whereas some cases are cured during childhood, most patients instead undergo palliation, which leaves them at risk for late complications. Lifelong clinical follow-up involving serial multimodality imaging is helpful to monitor and guide the treatment of late complications. Imaging of these individuals is challenging because of their unique anatomy and therefore requires careful consideration on a case-by-case basis...

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...

Vascular events in patients with coarctation of the aorta have been extensively reported and account for the majority of morbidity and mortality in untreated patients. The exact mechanism for this association is not completely understood and may include acquired anomalies or congenital abnormalities of intracranial vessel. Here we report a case of intracranial internal carotid artery dissection with subsequent formation of acquired large carotid aneurysm in a child with severe systemic hypertension and coarctation of the aorta...
