Reduction in baroreflex cardiovascular responses due to venous infusion in the rabbit. (1/10763)

We studied reflex bradycardia and depression of mean arterial blood pressure (MAP) during left aortic nerve (LAN) stimulation before and after volume infusion in the anesthetized rabbit. Step increases in mean right atrial pressure (MRAP) to 10 mm Hg did not result in a significant change in heart rate or MAP. After volume loading, responses to LAN stimulation were not as great and the degree of attenuation was propoetional to the level of increased MRAP. A change in responsiveness was observed after elevation of MRAP by only 1 mm Hg, corresponding to less than a 10% increase in average calculated blood volume. after an increase in MRAP of 10 mm Hg, peak responses were attenuated by 44% (heart rate) and 52% (MAP), and the initial slopes (rate of change) were reduced by 46% (heart rate) and 66% (MAP). Comparison of the responses after infusion with blood and dextran solutions indicated that hemodilution was an unlikely explanation for the attenuation of the reflex responses. Total arterial baroreceptor denervation (ABD) abolished the volume-related attenuation was still present following bilateral aortic nerve section or vagotomy. It thus appears that the carotid sinus responds to changes inblood volume and influences the reflex cardiovascular responses to afferent stimulation of the LAN. On the other hand, cardiopulmonary receptors subserved by vagal afferents do not appear to be involved.  (+info)

Quantification of baroreceptor influence on arterial pressure changes seen in primary angiotension-induced hypertension in dogs. (2/10763)

We studied the role of the sino-aortic baroreceptors in the gradual development of hypertension induced by prolonged administration of small amounts of angiotensin II (A II) in intact dogs and dogs with denervated sino-aortic baroreceptors. Short-term 1-hour infusions of A II(1.0-100 ng/kg per min) showed that conscious denervated dogs had twice the pressor sensitivity of intact dogs. Long-term infusions of A II at 5.0 ng/kg per min (2-3 weeks) with continuous 24-hour recordings of arterial pressure showed that intact dogs required 28 hours to reach the same level of pressure attained by denervated dogs during the 1st hour of infusion. At the 28th hour the pressure in both groups was 70% of the maximum value attained by the 7th day of infusion. Both intact and denervated dogs reached nearly the same plateau level of pressure, the magnitude being directly related both the the A II infusion rate and the daily sodium intake. Cardiac output in intact dogs initially decreased after the onset of A II infusion, but by the 5th day of infusion it was 38% above control, whereas blood volume was unchanged. Heart rate returned to normal after a reduction during the 1st day of infusion in intact dogs. Plasma renin activity could not be detected after 24 hours of A II infusion in either intact or denervated dogs. The data indicate that about 35% of the hypertensive effect of A II results from its acute pressor action, and an additional 35% of the gradual increase in arterial pressure is in large measure a result of baroreceptor resetting. We conclude that the final 30% increase in pressure seems to result from increased cardiac output, the cause of which may be decreased vascular compliance. since the blood volume remains unaltered.  (+info)

Blocking very late antigen-4 integrin decreases leukocyte entry and fatty streak formation in mice fed an atherogenic diet. (3/10763)

Atherosclerotic lesion development is characterized by the recruitment of leukocytes, principally monocytes, to the vessel wall. Considerable interest has been focused on the adhesion molecule(s) involved in leukocyte/endothelial interactions. The goal of the present study was to determine the role of the very late antigen-4 (VLA-4) integrin/ligand interaction in fatty streak development using murine models. Because alpha4 null mice are not viable, a peptidomimetic was used to block VLA-4-mediated leukocyte binding. The ability of a synthetic peptidomimetic of connecting segment-1 (CS-1 peptide) to block the recruitment of leukocytes and the accumulation of lipid in the aortic sinus of either wild-type mice (strain C57BL/6J) or mice with a low-density lipoprotein null mutation (LDLR-/-) maintained on an atherogenic diet was assessed. The active (Ac) CS-1 peptide or scrambled (Sc) CS-1 peptide was delivered subcutaneously into mice using a mini osmotic pump. Mice were exposed to the peptide for 24 to 36 hours before the onset of the atherogenic diet. In C57BL/6J mice, leukocyte entry into the aortic sinus, as assessed by en face preparations, was inhibited by the active peptide (Ac=28+/-4, Sc=54+/-6 monocytes/valve; P=0.004). Additionally, frozen sections stained with Oil Red O were analyzed to assess lipid accumulation in the aortic sinus. C57BL/6J mice that received the (Ac) compound demonstrated significantly reduced lesion areas as compared with mice that received the (Sc) peptide (Ac=4887+/-4438 microm2, Sc=15 009 +/-5619 microm2; P<0.0001). In a separate study, LDLR-/- mice were implanted with pumps containing either the (Ac) or (Sc) peptide before initiation of the atherogenic diet. Because LDLR-/- mice fed a chow diet displayed small lesions at 14 weeks, the effects of the peptide seen in these animals represented a change in early lipid accumulation rather than initiation. By using whole-mount preparations, the (Ac) but not the (Sc) peptide significantly reduced the area of lipid accumulation in the aortic sinus, resulting in an approximate 66% decrease. Plasma analysis from all studies revealed concentrations of peptide to be present at levels previously determined by in vitro analysis to block adhesion. (Ac) CS-1 peptide, which blocks VLA-4 on the leukocyte surface, is effective in reducing leukocyte recruitment and lipid accumulation in the aortic sinus. The present study provides in vivo evidence that the VLA-4 integrin plays an important role in the initiation of the atherosclerotic lesion and lipid accumulation, and it suggests a potential therapeutic strategy for this disease.  (+info)

Role of nitric oxide-cGMP pathway in adrenomedullin-induced vasodilation in the rat. (4/10763)

We previously reported that adrenomedullin (AM), a potent vasodilator peptide discovered in pheochromocytoma cells, stimulates nitric oxide (NO) release in the rat kidney. To further investigate whether the NO-cGMP pathway is involved in the mechanisms of AM-induced vasodilation, we examined the effects of E-4021, a cGMP-specific phosphodiesterase inhibitor, on AM-induced vasorelaxation in aortic rings and perfused kidneys isolated from Wistar rats. We also measured NO release from the kidneys using a chemiluminescence assay. AM (10(-10) to 10(-7) mol/L) relaxed the aorta precontracted with phenylephrine in a dose-dependent manner. Denudation of endothelium (E) attenuated the vasodilatory action of AM (10(-7) mol/L AM: intact (E+) -25.7+/-5.2% versus denuded (E-) -7. 8+/-0.6%, P<0.05). On the other hand, pretreatment with 10(-8) mol/L E-4021 augmented AM-induced vasorelaxation in the intact aorta (-49. 0+/-7.9%, P<0.05) but not in the denuded one. E-4021 also enhanced acetylcholine (ACh)-induced vasorelaxation in the rat intact aorta (10(-7) mol/L ACh -36.6+/-8.4% versus 10(-8) mol/L E-4021+10(-7) mol/L ACh -62.7+/-3.1%, P<0.05). In perfused kidneys, AM-induced vasorelaxation was also augmented by preincubation with E-4021 (10(-9) mol/L AM -15.4+/-0.6% versus 10(-8) mol/L E-4021+10(-9) mol/L AM -23.6+/-1.2%, P<0.01). AM significantly increased NO release from rat kidneys (DeltaNO: +11.3+/-0.8 fmol. min-1. g-1 kidney at 10(-9) mol/L AM), which was not affected by E-4021. E-4021 enhanced ACh-induced vasorelaxation (10(-9) mol/L ACh -9.7+/-1.7% versus 10(-8) mol/L E-4021+10(-9) mol/L ACh -18.8+/-2.9%, P<0.01) but did not affect ACh-induced NO release from the kidneys. In the aorta and the kidney, 10(-4) mol/L of NG-nitro-L-arginine methyl ester, an NO synthase inhibitor, and 10(-5) mol/L of methylene blue, a guanylate cyclase inhibitor, reduced the vasodilatory effect of AM. These results suggest that the NO-cGMP pathway is involved in the mechanism of AM-induced vasorelaxation, at least in the rat aorta and kidney.  (+info)

Different contributions of endothelin-A and endothelin-B receptors in the pathogenesis of deoxycorticosterone acetate-salt-induced hypertension in rats. (5/10763)

We investigated the involvement of actions mediated by endothelin-A (ETA) and endothelin-B (ETB) receptors in the pathogenesis of deoxycorticosterone acetate (DOCA)-salt-induced hypertension in rats. Two weeks after the start of DOCA-salt treatment, rats were given ABT-627 (10 [mg/kg]/d), a selective ETA receptor antagonist; A-192621 (30 [mg/kg]/d), a selective ETB receptor antagonist; or their vehicle for 2 weeks. Uninephrectomized rats without DOCA-salt treatment served as controls. Treatment with DOCA and salt for 2 weeks led to a mild but significant hypertension; in vehicle-treated DOCA-salt rats, systolic blood pressure increased markedly after 3 to 4 weeks. Daily administration of ABT-627 for 2 weeks almost abolished any further increases in blood pressure, whereas A-192621 did not affect the development of DOCA-salt-induced hypertension. When the degree of vascular hypertrophy of the aorta was histochemically evaluated at 4 weeks, there were significant increases in wall thickness, wall area, and wall-to-lumen ratio in vehicle-treated DOCA-salt rats compared with uninephrectomized control rats. The development of vascular hypertrophy was markedly suppressed by ABT-627. In contrast, treatment with A-192621 significantly exaggerated these vascular changes. In vehicle-treated DOCA-salt rats, renal blood flow and creatinine clearance decreased, and urinary excretion of protein, blood urea nitrogen, fractional excretion of sodium, and urinary N-acetyl-beta-glucosaminidase activity increased. Such damage was overcome by treatment with ABT-627 but not with A-192621; indeed, the latter agent led to worsening of the renal dysfunction. Histopathologic examination of the kidney in vehicle-treated DOCA-salt rats revealed tubular dilatation and atrophy as well as thickening of small arteries. Such damage was reduced in animals given ABT-627, whereas more severe histopathologic changes were observed in A-192621-treated animals. These results strongly support the view that ETA receptor-mediated action plays an important role in the pathogenesis of DOCA-salt-induced hypertension. On the other hand, it seems likely that the ETB receptor-mediated action protects against vascular and renal injuries in this model of hypertension. A selective ETA receptor antagonist is likely to be useful for treatment of subjects with mineralocorticoid-dependent hypertension, whereas ETB-selective antagonism alone is detrimental to such cases.  (+info)

AMP-activated protein kinase phosphorylation of endothelial NO synthase. (6/10763)

The AMP-activated protein kinase (AMPK) in rat skeletal and cardiac muscle is activated by vigorous exercise and ischaemic stress. Under these conditions AMPK phosphorylates and inhibits acetyl-coenzyme A carboxylase causing increased oxidation of fatty acids. Here we show that AMPK co-immunoprecipitates with cardiac endothelial NO synthase (eNOS) and phosphorylates Ser-1177 in the presence of Ca2+-calmodulin (CaM) to activate eNOS both in vitro and during ischaemia in rat hearts. In the absence of Ca2+-calmodulin, AMPK also phosphorylates eNOS at Thr-495 in the CaM-binding sequence, resulting in inhibition of eNOS activity but Thr-495 phosphorylation is unchanged during ischaemia. Phosphorylation of eNOS by the AMPK in endothelial cells and myocytes provides a further regulatory link between metabolic stress and cardiovascular function.  (+info)

RNA antisense abrogation of MAT1 induces G1 phase arrest and triggers apoptosis in aortic smooth muscle cells. (7/10763)

The human MAT1 gene (menage a trois 1) is an assembly factor and a targeting subunit of cyclin-dependent kinase (CDK)-activating kinase. The novel mechanisms by which MAT1 forms an active CDK-activating kinase and determines substrate specificity of CDK7-cyclin H are involved in the cell cycle, DNA repair, and transcription. Hyperplasia of vascular smooth muscle cells (SMC) is a fundamental pathologic feature of luminal narrowing in vascular occlusive diseases, and nothing is yet known regarding the cell cycle phase specificity of the MAT1 gene in its involvement in SMC proliferation. To investigate such novel regulatory pathways, MAT1 expression was abrogated by retrovirus-mediated gene transfer of antisense MAT1 RNA in cultured rat aortic SMCs. We show that abrogation of MAT1 expression retards SMC proliferation and inhibits cell activation from a nonproliferative state. Furthermore, we have demonstrated that these effects are due to G1 phase arrest and apoptotic cell death. Our studies indicate a link between cell cycle control and apoptosis and reveal a potential mechanism for coupling the regulation of MAT1 with G1 exit and prevention of apoptosis.  (+info)

Endogenous plasma endothelin concentrations and coronary circulation in patients with mild dilated cardiomyopathy. (8/10763)

OBJECTIVE: To determine whether increased plasma concentrations of endothelin-1 (ET-1) and big endothelin (BET) play a role in the regulation of coronary circulation in patients with idiopathic dilated cardiomyopathy (IDCM). SETTING: Tertiary referral centre for cardiac diseases. PATIENTS: Fourteen patients (eight male/six female; mean (SD) age 59 (9) years) with IDCM (ejection fraction 36 (9)%) and five normotensive subjects (two male/three female; age 52 (7) years) serving as controls were studied. METHODS: Functional status was classified according to New York Heart Association (NYHA) class. Endogenous ET-1 and BET plasma concentrations from the aorta and the coronary sinus were determined by radioimmunoassay. Coronary blood flow, using the inert chromatographic argon method, myocardial oxygen consumption, and coronary sinus oxygen content under basal conditions were determined. RESULTS: In the aorta, mean (SD) concentrations of ET-1 (IDCM 0.76 (0.25) v controls 0.31 (0.06) fmol/ml; p = 0.002) and BET (IDCM 3.58 (1.06) v controls 2.11 (0.58) fmol/ml; p = 0.014) were increased in patients with IDCM. Aortic ET-1 concentrations correlated positively with NYHA class (r = 0. 731; p < 0.001), myocardial oxygen consumption (r = 0.749; p < 0. 001), and coronary blood flow (r = 0.645; p = 0.003), but inversely with coronary sinus oxygen content (r = -0.633; p = 0.004), which was significantly decreased in IDCM patients (IDCM 4.68 (1.05) v controls 6.70 (1.06) vol%; p = 0.003). CONCLUSIONS: The coronary circulation in patients with IDCM is exposed to an increased endothelin load. ET-1 concentrations correlate with functional deterioration. A decrease of the coronary sinus content of oxygen suggests a mismatch between coronary blood flow and metabolic demand. Thus, ET-1 might be a marker of a disequilibrium between myocardial oxygen demand and coronary blood flow in IDCM.  (+info)

The SphygmoCor® CP System The SphygmoCor CP system includes pulse wave analysis (PWA) software only. During a PWA measurement, a 10-second snapshot of the radial arterial pressure wave is measured using a tonometer. The SphygmoCor software derives the ascending aortic pressure wave, substantially equivalent to the pressure wave measured by an invasive catheter. From the aortic pressure wave, a number of valuable cardiovascular measurements are determined, including central aortic systolic pressure, aortic augmentation index and central pulse pressure ...
The compliance of the aorta, which is a function of the wall properties, e.g. material, thickness and geometry, is a hallmark of cardiovascular flows. Expansion and contraction of the aortic wall is believed to considerably influence the flow features. The compliance characteristics are associated with aging which is one of the primary causes of arterial stiffening. A three-dimensional pulsatile aortic flow in a human ascending aorta is studied to investigate the effect of the aortic stiffness on the flow field and turbulent fluctuating velocities in the ascending aorta. A non-intrusive optical measurement technique, 3D Particle Tracking Velocimetry (3D-PTV), has been applied to anatomically accurate phantoms under clinically realistic conditions. A compliant silicon phantom was used to mimic the healthy aorta and a rigid model was used to imitate the pathological case that appears in aortas for example as a result of aging. Our results revealed that the aortic stiffness leads to an increase in ...
In the present study, we addressed 2 questions that are pertinent to vascular aging. First, we determined whether aging is associated with the lengthening or elongation of the aorta and large conduit arteries. We found that the length of the ascending aorta increased significantly with advancing age, whereas the descending aorta did not demonstrate age-associated lengthening. The age-related elongation of the ascending aorta was associated with the corresponding increase in central arterial stiffness and pulse wave amplification, suggesting that the reduction in the elastic property as well as local pulsatile pressure might play a causative role. Second, we determined what impact the aortic elongation has on PWV, which is 1 of the most established measures of arterial stiffness. We found that age-related aortic elongation has little impact on PWV measurement because the segment of the ascending aorta is omitted from the arterial length measurements for carotid-femoral PWV. Moreover, the most ...
Fluid flow induced significant increases in the FGF-2 content in the circulating medium and in the pericellular region. At a shear stress level of 25 dyne/cm2, there was a 1.5-fold increase in the pericellular FGF-2 content, which represents release of 15% of the total FGF-2 in the cell (Figure 4⇑). The release was rapid in view of the fact that it occurred at ≤15 minutes and thus did not depend on the de novo synthesis of FGF-2. This release was not sustained, as seen by the decay in medium levels with time (Figure 1⇑), which can be explained by the adsorption of FGF-2 to the surfaces of the experimental system. The half-life of FGF-2 in the flow system (Figure 2⇑) is ≈4 hours. This means that FGF-2 will adsorb to surfaces after prolonged contact, and data points beyond 4 hours represent significant loss due to this adsorption. Because the release response found in the present study was rapid, adsorption did not represent a significant loss in the first 15 minutes. Furthermore, FGF-2 ...
The aorta is a large artery with a thick wall. This is necessary for it to handle a large volume of blood exiting the heart and contend with high pressure. However, there are several reasons why the inner lining of the wall can be compromised. This can cause the inner lining to tear. The blood under high pressure may then enter the wall of the aorta and create a channel for the blood between the inner and middle layer.. It is more likely to occur if the blood pressure rises to levels that are too high. Another factor is that wall of the aorta may be weakened. However, in most cases the blood may not extend beyond the middle layer of the aortic wall. Fortunately this middle layer is significantly strong to withstand the high pressure for a period of time. Eventually the blood can penetrate through the middle layer and lead to a rupture of the aorta.. Blood may then pour out of the aorta from where it bursts. As a result the blood pressure cannot be maintained at normal levels and oxygen-rich ...

Our understanding of aortic biomechanics is customarily limited by lack of information on the axial residual stretches of the vessel in both humans and experimental animals that would facilitate the identification of its actual zero-stress state. The aim of this study was thus to acquire hitherto unreported quantitative knowledge of axial opening angle and residual stretches in different segments and quadrants of the human aorta according to age and gender. Twenty-three aortas were harvested during autopsy from the aortic root to the iliac bifurcation and were divided into ≥12 segments and 4 quadrants. Morphometric measurements were taken in the excised/curled configuration of rectangular strips considered to be under zero-stress using image-analysis software to study the axial/circumferential variation of axial opening angle, internal/external residual stretch, and thickness of the aortic wall. The measured data demonstrated: (1) an axial opening angle peak at the arch branches, decreasing ...

Aims - Aortic adaptive immunity plays a crucial role in atherosclerosis; however, the precise mechanisms leading to T cell activation in the arterial wall remain poorly understood. Methods and Results - Here we have identified naïve T cells in the aorta of wild-type and TCR transgenic mice and we demonstrate that naïve T cells can be primed directly in the vessel wall with a similar activation profile to splenic and lymphoid T cells. Aortic homing of naïve T cells is regulated at least in part by the P-selectin glycosylated ligand-1 (PSGL-1) receptor. In experimental atherosclerosis the aorta supports CD4+ T cell activation selectively driving Th1 polarization. By contrast, secondary lymphoid organs display Treg expansion. Conclusions - Our results demonstrate that the aorta can support T cell priming and that naïve T cells traffic between the circulation and vessel wall. These data underpin the paradigm that local priming of T cells specific for plaque antigens contributes to atherosclerosis
Each primitive aorta receives anteriorly a vein the vitelline vein from the yolk-sac, and is prolonged backward on the lateral aspect of the notochord under the name of the dorsal aorta. The dorsal aortae give branches to the yolk-sac, and are continued backward through the body-stalk as the umbilical arteries to the villi of the chorion. The two dorsal aortae combine to become the descending aorta in later development[WP].. ...

The aorta originates from the left ventricle of the heart. It ends in the abdomen where it branches into the two common iliac arteries. The aorta has five separate segments. The descending aorta begins at the arch of the aorta (where it loops over the heart to begin its descent).
OBJECTIVE: To evaluate blood-volume flow-rate measurement in the fetal descending thoracic aorta using a non-invasive, non-Doppler, ultrasound technique. METHODS: This was a cross-sectional, observational study. Volume flow measurements were obtained from the descending thoracic aorta in 59 human fetuses between 20 and 40 weeks gestation. These were uncomplicated pregnancies that resulted in the live births of appropriately grown infants. The measurements were obtained using a time domain processing technique: color velocity imaging quantification (CVI-Q). RESULTS: The blood-volume flow rate increased consistently from the second trimester until term. The mean values ranged between 100 mL/min at 20 weeks gestation and approximately 350 mL/min at term. The normalized (weight-adjusted) volume flow rates decreased with increasing gestation, from a maximum of 626 mL/min/kg at 23 weeks to a minimum of 45.6 mL/min/kg at 37 weeks. CONCLUSIONS: The regular measurement of blood-volume flow in the ...
The functions of resident CD11c+ myeloid cells in healthy mouse aorta and in the initiation of atherosclerosis. In atherosclerotic lesions, myeloid cells (macrophages and dendritic cells) and oxidatively-modified lipids accumulate underneath the endothelium in the arterial intima (the inner layer of the artery facing the lumen). Previously, we showed that in the normal mouse aorta CD11c+ myeloid cells reside preferentially in regions predisposed to atherosclerosis. Upon feeding a high cholesterol diet to atherosclerosis-susceptible low-density lipoprotein receptor deficient (LDLR-/-) mice, intimal CD11c+ cells accumulate intracellular lipid even prior to the recruitment of blood monocytes. Collectively, our studies showed that the low-grade monocyte recruitment in lesion-prone regions of the aorta accounts for resident intimal CD11c+ myeloid cell accumulation in the steady state, and that these cells promote atherosclerotic lesion formation and monocyte recruitment to the aortic intima in the ...
The air-filled ring was initially placed around the ascending aorta through a small tunnel in the periaortic fat. Extreme care was taken to avoid, as far as possible, damage of the penetrating vasa vasorum.1 When the hemodynamic condition of the animal was considered stable, the filling pressure of the ring was adjusted to be 60 mm Hg at diastole; this filling pressure was in every case below the aortic diastolic pressure of the animal, so that the ring would be in gentle contact with the aortic wall. At systole, the filling pressure of the ring increased by approximately 5 mm Hg because of the distension of the aorta (the exact value depended on the amount of distension of the aorta). Conditions of contact between the ring and the aortic wall were stable throughout the experiment. After placement of the ring, changes of the aortic diameter were recorded simultaneously with the ECG and the aortic pressures at a paper speed of 50 mm/s. To evaluate the data of each experimental subject, 10 ...

We thank Dr. Nelson and colleagues for their interest in our recent work concerning the effect of age on the biomechanical properties of the human aorta (1). We observed the greatest age-related difference in the aortic pulse wave velocity in the distal abdominal aorta, and the least in the aortic arch, suggesting that the distal aorta stiffened most with age. As we noted in our discussion, and as Dr. Nelson and colleagues reiterate, others have reported the converse, that is, that the ascending aorta stiffens most with age (2,3). No doubt, there are several explanations for these discrepant observations, not least the very small sample sizes reported by some authors (2,3), the use of differing techniques to estimate regional stiffness, methodological issues such as the use of nonsimultaneous, peripheral pressure when calculating distensibility/compliance (3), and technical issues such as inaccurate edge detection with cardiac magnetic resonance with varying sequences (4). Interestingly, a ...

Causes of Coarctation of aorta dominant including triggers, hidden medical causes of Coarctation of aorta dominant, risk factors, and what causes Coarctation of aorta dominant.
Coarctation of the aorta is a small narrowing of the big artery that pumps blood from the heart to the rest of body (the aorta). This makes it hard for the blood to flow from the heart to the lower part of the body. The blood backs up above the narrow area, causing higher blood pressure in the arms and in the blood vessels going to the head than in the legs. In severe cases, no blood can get through the narrow area. Severe coarctation of the aorta in a newborn infant is a medical emergency that can result in death if it’s not treated.. ...

Anevrismul aortic reprezinta o zona slabita si „umflata in peretele aortei. Aorta este vasul de sange de dimensiuni mari, care transporta sangele bogat in oxigen de la inima la restul organismului. Aorta anevrismala este slabita si se poate rupe, determinand o hemoragie ce poate pune in pericol viata. Ruperea anevrismului aortic este pe locul 15 in lista cauzelor de deces si apare la una din 12 persoane in varsta. Exista 2 tipuri de anevrism aortic: anevrismul aortic abdominal si anevrismul aortic toracic. Aceasta clasificare se bazeaza pe localizarea anevrismului de-a lungul traiectului aortei. Regiunea toracica a aortei traverseaza partea de sus (toracica) a corpului si furnizeaza sange bogat in oxigen in aceasta regiune. Regiunea abdominala a aortei este in continuarea celei toracice, de-a lungul abdomenului si asigura aportul de sange bogat in oxigen in partea de jos a corpului. Anevrismele pot aparea in orice zona a aortei, dar cel mai frecvent apar in partea abdominala.. #gallery-1 { ...

Double aortic arch is a common form of a group of defects that affect the development of the aorta in the womb. These defects cause an abnormal formation called a vascular ring (a circle of blood vessels).. Normally, the aorta develops from one of several curved pieces of tissue (arches). As babies develop in the womb, the arches split into several parts. The body breaks down some of the arches, while others form into arteries. A normally developed aorta is a single arch that leaves the heart and moves leftward.. In double aortic arch, some of the arches that should have disappeared are still present at birth in addition to the normal arch. Babies with a double aortic arch have an aorta that is made up of two vessels instead of one. The two parts to the aorta have smaller arteries branching off of them. As a result, the two branches go around and press down on the windpipe and the tube (esophagus) that carries food from the mouth to the stomach. A double aortic arch may occur in other congenital ...

  • Preductal coarctation results when an intracardiac anomaly during fetal life decreases blood flow through the left side of the heart, leading to hypoplastic development of the aorta. (wikipedia.org)
  • Postductal coarctation is most likely the result of the extension of a muscular artery (ductus arteriosus) into an elastic artery (aorta) during fetal life, where the contraction and fibrosis of the ductus arteriosus upon birth subsequently narrows the aortic lumen. (wikipedia.org)
  • Some children born with coarctation of the aorta have other heart defects too, such as aortic stenosis, ventricular septal defect, patent ductus arteriosus or mitral valve abnormalities. (wikipedia.org)
  • When someone has coarctation (pronounced: ko-ark-TAY-shun) of the aorta , that person's aorta is narrowed at some point. (kidshealth.org)
