Aortic dissection is a life threatening cardiovascular catastrophy. Its incidence estimated to 5-6 cases per 100,000 patients/year. The intimal tear happens at the ascending aorta in Type A, meanwhile at the aortic isthmus in Type B, but entry point may develop anywhere alongside the entire aorta. All types may affect a short aortic segment resulting in a localized false aneurysm, others separate the intimal layer at longer extension down to the visceral segment and far beyond to the femoral arteries. Dissection of orifices of side branches may lead to cerebral, upper extremity, spinal, visceral, renal and lower extremity malperfusion...

BACKGROUND: Re-entrant atrial arrhythmias are common in patients after cardiac surgery. To date, however, no studies have reported the safety and efficacy of radiofrequency (RF) ablation of macro-re-entrant atrial arrhythmias in a unique, homogeneous group of patients after surgical replacement of the aortic valve and single right atriotomy. METHODS: Among over 4,000 RF catheter ablations performed at the authors' center between 2008 and 2014, eight patients (seven males, one female; mean age 55...

A 77-year-old man with a descending thoracic aneurysm associated with pseudocoarctation of the aorta underwent thoracic endovascular aortic repair (TEVAR). Computed tomography demonstrated kinking of the descending thoracic aorta. The aneurysm was located distal to a kinking and constricting aortic isthmus. TEVAR was performed because of the patient's comorbidity such as valvular heart diseases and postradiation status for the thoracic Hodgkin disease. TEVAR was successful but small aortic dissection was occurred distal to the stentgraft...

BACKGROUND: Aortic arch abnormalities represent 5% to 8% of all congenital heart disease. Measurements of the aortic arch dimensions on two-dimensional echocardiographic images remain of critical importance in the diagnosis of aortic arch pathology. To define aortic hypoplasia or coarctation, measured dimensions must be compared with normal values. Normal values have been described for children of all ages in earlier studies. However, normative data for premature infants are not yet available...

INTRODUCTION: Substernal goiters are characterized by the protrusion of at least 50% of the thyroid mass below the level of the thoracic inlet. Still their definition is controversial. CASE PRESENTATION: The case refers to a 44year old male who presented to our department due to swelling and a feeling of 'heaviness' of his left upper extremity for the past 6 months. CT scan revealed a massive substernal goiter extending to the great vessels. Intraoperatively, a median sternotomy was performed due to the size of the gland and the close adhesion of the isthmus and lower left thyroid lobe to the brachiocephalic vein...

OBJECTIVE: To analyze the findings of aortic floating thrombus (AFT) on computed tomography angiography (CTA) for a definitive, timely diagnosis and to select a reasonable management course to improve prognosis. METHOD: We retrospectively analyzed imaging findings of 5 patients with AFT detected by CTA, including location, morphology, size, involved aortic segment, concomitant embolism, stent, and dynamic changes during the follow-up. RESULTS: Seven lesions were detected in the initial CTA studies of the 5 patients: 5 aortic intraluminal floating thrombi (3 patients) and 2 aortic in-stents floating thrombi (ASFTs; 2 patients)...

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...

OBJECTIVES: Endovascular repair of traumatic injury of the aortic isthmus is a safe technique that has shown good short-term results. However, the future of these stent grafts remains unexamined, especially in relation to young patients. METHOD: Between January 2000 and December 2014, 60 patients were treated with endovascular aortic stent graft for injury of the aortic isthmus. Follow-up was done by computed tomography scans with intravenous contrast or magnetic resonance imaging associated with a chest X-ray in order to control the stent graft...

BACKGROUND: Prenatal diagnosis of coarctation of the aorta (CoA) is still challenging and affected by high rates of false-positive diagnoses. The aim of this study was to ascertain the strength of association and to quantify the diagnostic accuracy of different ultrasound signs in predicting CoA prenatally. METHODS: Medline, Embase, CINAHL, and Cochrane databases were searched. Random-effects and hierarchical summary receiver operating characteristic model meta-analyses were used to analyze the data...

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...

OBJECTIVES: Since postnatal identification of accelerated idioventricular rhythm (AIVR) is essentially based on specific electrocardiographic patterns, its prenatal diagnosis is challenging and its genuine incidence undetermined. Therefore the objectives of this study are: 1) To evaluate the performance of specific ultrasonographic approaches in intrauterine identification of cardiocirculatory events linked to electrocardiographic signs of AIVR, including its left or right ventricular origin, and 2) To assess the prenatal prognosis of the arrhythmia...

Aortic rupture and transection are constituents of the acute aortic syndrome. Injury to the thoracic aorta during motor vehicle crashes is associated with blunt chest trauma and rapid deceleration mechanisms. Type A dissections and/or rupture of the aorta at the level of the aortic isthmus are the more common presentations of aortic injuries associated with motor vehicle crashes. We present the case of atypical echocardiographic findings of a nearly complete circumferential transection of the proximal ascending aorta injury after a motorcycle crash...

OBJECTIVE: Global racial variability in human development can lead to differences in size of fetal cardiac structures during gestation. Our objective is to establish normal reference ranges of fetal cardiac dimensions between 20 and 34 weeks from fetal echocardiograms recorded at a single center in China. METHODS: A prospective cross-sectional study was undertaken on single pregnancies with normal fetuses of varying gestational ages (GAs). A total of 4396 normal fetuses were divided into 15 groups from 20 to 34 weeks according to the GA...

Aortic coarctation rarely occurs after an arterial switch operation for D-transposition of the great arteries with intact ventricular septum. We report the case of a neonate patient in whom aortic coarctation developed 28 days after an uncomplicated arterial switch operation. Preoperatively, the aorta was noted to have an irregular shape, but there was no pressure gradient across the lesion. The patient underwent successful reoperation to correct the coarctation. We hope that our report raises awareness of a rare early complication after arterial switch operation with intact ventricular septum, and the need to carefully monitor the aortic isthmus in patients who have aortic irregularities, even in the absence of a pressure gradient...

OBJECTIVE: Vein of Galen aneurysmal malformation (VGAM) is a rare anomaly in which an adequate perinatal management may warrant good neurological outcome. However, most fetal series are too scant to allow reliable statistical assessment of poor prognostic factors. Aim of this paper is to assess, in a two-center series of 49 cases, the prognostic value of several prenatal variables. The primary endpoint of the analysis is to identify possible prenatal indicators of poor outcome, in terms of mortality and cerebral disabilities...

Traumatic aortic rupture is rupture of all or part of the aortic wall, mostly resulting from blunt trauma to the chest. The most common site of rupture is the aortic isthmus. Traumatic rupture of the ascending aorta is rare. A 62-year-old man with a family history of ascending aortic aneurysm was referred to our hospital after a motor vehicle accident. He had symptoms of cardiogenic shock. A contrast-enhanced computed tomographic scan revealed rupture of the proximal ascending aorta and an ascending aortic aneurysm with a diameter of 55 mm at the level of the sinuses of Valsalva...

Prenatal diagnosis of tetralogy of Fallot remains less frequent compared to other major congenital heart defects. In this study, we examined how often the 3-vessel and trachea view was abnormal in a large series of prenatally diagnosed cases of tetralogy of Fallot. In addition, we compared its sensitivity to that of the traditional outflow tract views for detection of tetralogy of Fallot. We found that both views were abnormal in all fetuses with tetralogy of Fallot, showing reversed aortic-to-pulmonary valve and aortic arch isthmus-to-ductus arteriosus ratios in the outflow tract and 3-vessel and trachea views, respectively...

The aortic isthmus (AoI) is a unique fetal watershed with a waveform reflecting its complex haemodynamic physiology. The systolic component represents left and right ventricular systolic ejection, and the diastolic component represents comparative downstream vascular impedance between the brachiocephalic and subdiaphragmatic fetal circulations. Several indices have been devised to quantify different components of the waveform, including the pulsatility index, resistance index, isthmic flow index, and recently the isthmic systolic index...
