BACKGROUND: In aortic coarctation, current guidelines recommend reducing pressure gradients that exceed given thresholds. From a physiological standpoint this should ideally improve the energy expenditure of the heart and thus prevent long term organ damage. OBJECTIVES: The aim was to assess the effects of interventional treatment on external and internal heart power (EHP, IHP) in patients with aortic coarctation and to explore the correlation of these parameters to pressure gradients obtained from heart catheterization...

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...

Interventional cardiac catheterization has a major place in the management of congenital heart disease. Since the Rashkind atrioseptostomy in mid-1960s, many techniques have been developed. For some, it is necessary to close a cardiac or extracardiac shunt using occluder (double disc system, plug, coil…): closure of atrial septal defect, ventricular septal defect or patent arterial duct. For others, it is necessary to treat a valvular or vascular stenosis using a balloon catheter: dilatation of the pulmonary or the aortic valve, dilatation of aortic coarctation...

PURPOSE: To present a case of mycobacterium infection transmitted through a heater-cooler unit during cardiac bypass surgery. CLINICAL FEATURES: A 63-yr-old woman with a past medical history of aortic coarctation repair in 1963 and a mechanical aortic valve replacement in 2010 was prescribed antibiotics and steroids at an outpatient care facility in September 2015 for symptoms of an upper respiratory tract infection. Four months later, she developed malaise and intermittent fever with anemia and acute kidney dysfunction...

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...

REVIEW
Luis E De León, E Dean McKenzie
The optimal treatment of patients with complex coarctation of the aorta and hypoplastic aortic arch is controversial. Children undergoing repair of obstructive arch lesions are at lifelong risk of recurrence. Multiple techniques have been described to address complex primary and recurrent coarctation. Our approach at Texas Children's Hospital (Houston, TX) has been to address these lesions in an anatomic fashion via median sternotomy, under cardiopulmonary bypass using the techniques of aortic arch advancement and ascending sliding arch aortoplasty...

Coarctation of the aorta (CoA) is defined as a congenital stenosis of the thoracic aorta and is one of the most common congenital cardiovascular diseases. Despite successful surgical treatment for CoA, arterial abnormalities, including refractory hypertension, aortic aneurysm, and proatherogenic phenotypic changes, frequently affect patients' quality of life. Emerging evidence from morphological and molecular biological investigations suggest that the area of CoA is characterized by phenotypic modulation of smooth muscle cells, intimal thickening, and impaired elastic fiber formation...

The aim was to investigate the impact of maternal hyperoxygenation (HO) on cardiac dimensions in fetuses with isolated Coarctation (CoA). Fetal echocardiography was performed serially in 48 fetuses with CoA and gestation age matched normal fetues. The Z-scores for the mitral valve (MV), tricuspid valve (TV), aortic valve (AV), ascending aorta (AAo), isthmus, pulmonary valve (PV), main pulmonary artery (MPA), and descending aorta (DAo) were measured and compared among normal fetuses, CoA fetuses with oxygen and CoA fetuses with air...

BACKGROUND: Shone complex consists of a constellation of left-sided, usually obstructive, cardiac lesions, including supravalvar mitral ring, parachute mitral valve, subaortic stenosis, and aortic coarctation. Incomplete Shone complex consists of a mitral valve anomaly associated with lesions involving the subaortic region, aortic valve, or thoracic aorta. There is a paucity of data regarding long-term outcomes in adults with Shone complex. METHODS: We reviewed records of adults with complete or incomplete Shone complex followed at the Montreal Heart Institute between 1982 and 2014...

INTRODUCTION: One of the most important problems in patients with an aortic coarctation after an aortic arch repair is future cardiovascular disease. We previously reported the enhancement of the aortic pressure wave reflection in patients and hypothesized that the enhancement was caused by a new pressure wave reflection generated from the repaired site. To prove the hypothesis, we analyzed the pressure waveform in the ascending and descending aorta and examined their pulse pressure (PP) amplification...

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...
