Elastic and collagenous networks in vascular diseases. (1/33)

Supravalvular aortic stenosis (SVAS), Marfan syndrome (MFS) and Ehlers-Danlos syndrome type IV (EDS IV) are three clinical entities characterized by vascular abnormalities that result from mutations of structural components of the extracellular matrix (ECM). Analyses of naturally occurring human mutations and of artificially generated deficiencies in the mouse have provided insights into the pathogenesis of these heritable disorders of the connective tissue. SVAS is associated with haploinsufficiency of elastin, one of the two major components of the elastic fibers. SVAS is characterized by narrowing of the arterial lumen due to the failure of regulation of cellular proliferation and matrix deposition. Mutations in fibrillin 1 are the cause of dissecting aneurysm leading to rupture of the ascending aorta. Fibrillin-1 is the building block of the microfibrils that span the entire thickness of the aortic wall and are a major component of the elastic fibers that reside in the medial layer. The vascular hallmark of EDS IV is rupture of large vessels. The phenotype is caused by mutations in type III collagen. The mutations ultimately affect the overall architecture of the collagenous network and the biomechanical properties of the adventitial layer of the vessel wall. Altogether, these genotype-phenotype correlations document the diversified contributions of distinct extracellular macroaggregates to the assembly and function of the vascular matrix.  (+info)

Hypoplastic left heart syndrome. (2/33)

Hypoplastic left heart syndrome may be accurately diagnosed during fetal life. Prenatal diagnosis provides the opportunity for parents to make an informed choice about their options, including surgery, nonintervention postnatally or termination of pregnancy. Short to medium term survival continues to improve for a condition that was previously invariably lethal. There continues to be a significant mortality and morbidity associated with hypoplastic left heart syndrome, and the long-term prognosis is unknown. Knowledge of the condition prior to birth means that babies who are to undergo surgery present in optimal condition for such interventions. Parents who have had an affected fetus or child should be offered detailed fetal echocardiography to exclude a recurrence in subsequent pregnancies.  (+info)

Elastin: mutational spectrum in supravalvular aortic stenosis. (3/33)

Supravalvular aortic stenosis (SVAS) is a congenital narrowing of the ascending aorta which can occur sporadically, as an autosomal dominant condition, or as one component of Williams syndrome. SVAS is caused by translocations, gross deletions and point mutations that disrupt the elastin gene (ELN) on 7q11.23. Functional hemizygosity for elastin is known to be the cause of SVAS in patients with gross chromosomal abnormalities involving ELN. However, the pathogenic mechanisms of point mutations are less clear. One hundred patients with diagnosed SVAS and normal karyotypes were screened for mutations in the elastin gene to further elucidate the molecular pathology of the disorder. Mutations associated with the vascular disease were detected in 35 patients, and included nonsense, frameshift, translation initiation and splice site mutations. The four missense mutations identified are the first of this type to be associated with SVAS. Here we describe the spectrum of mutations occurring in familial and sporadic SVAS and attempt to define the mutational mechanisms involved in SVAS. SVAS shows variable penetrance within families but the progressive nature of the disorder in some cases, makes identification of the molecular lesions important for future preventative treatments.  (+info)

Connection between elastin haploinsufficiency and increased cell proliferation in patients with supravalvular aortic stenosis and Williams-Beuren syndrome. (4/33)

To elucidate the pathomechanism leading to obstructive vascular disease in patients with elastin deficiency, we compared both elastogenesis and proliferation rate of cultured aortic smooth-muscle cells (SMCs) and skin fibroblasts from five healthy control subjects, four patients with isolated supravalvular aortic stenosis (SVAS), and five patients with Williams-Beuren syndrome (WBS). Mutations were determined in each patient with SVAS and in each patient with WBS. Three mutations found in patients with SVAS were shown to result in null alleles. RNA blot hybridization, immunostaining, and metabolic labeling experiments demonstrated that SVAS cells and WBS cells have reduced elastin mRNA levels and that they consequently deposit low amounts of insoluble elastin. Although SVAS cells laid down approximately 50% of the elastin made by normal cells, WBS cells deposited only 15% of the elastin made by normal cells. The observed difference in elastin-gene expression was not caused by a difference in the stability of elastin mRNA in SVAS cells compared with WBS cells, but it did indicate that gene-interaction effects may contribute to the complex phenotype observed in patients with WBS. Abnormally low levels of elastin deposition in SVAS cells and in WBS cells were found to coincide with an increase in proliferation rate, which could be reversed by addition of exogenous insoluble elastin. We conclude that insoluble elastin is an important regulator of cellular proliferation. Thus, the reduced net deposition of insoluble elastin in arterial walls of patients with either SVAS or WBS leads to the increased proliferation of arterial SMCs. This results in the formation of multilayer thickening of the tunica media of large arteries and, consequently, in the development of hyperplastic intimal lesions leading to segmental arterial occlusion.  (+info)

Supravalvular aortic stenosis and peripheral pulmonary stenosis coexisting with a straight thoracic spine. (5/33)

Supravalvular aortic stenosis (SVAS) is recognized in cases of Williams syndrome and in sporadic cases not associated with other features of the syndrome. It is also well recognized as associated with peripheral pulmonary stenosis (PPS). A male patient was diagnosed as having PPS at the age of 1 year and 8 months, and was found at the age of 18 years to have SVAS. Cardiac catheterization showed that he had a localized type of SVAS and regression of the PPS. Chest X-ray showed that he did not have the normal thoracic curvature. His 19-year-old sister had also been diagnosed with PPS, and his 43-year-old mother was known to have a harsh systolic cardiac murmur of unknown etiology. Cardiac magnetic resonance imaging showed a localized type of SVAS in his mother also, though not in his sister, both of whom had a somewhat straight thoracic spine, most noticeably in the mother, though not to the degree observed in the patient. This case appears to be familial, though it is not clear whether this skeletal abnormality is an unknown phenotypic feature of this cardiovascular disease.  (+info)

Williams syndrome associated with complete atrioventricular septal defect. (6/33)

Williams syndrome is a genetic disorder associated with characteristic facies, supravalvar aortic stenosis, peripheral pulmonary stenosis, mental retardation, hypertension, premature aging of skin, and congenital cardiac defects. Many cardiac defects such as bicuspid aortic valve, mitral valve regurgitation, coarctation of the aorta, and ventricular or atrial septal defects are linked to the syndrome. Complete atrioventricular septal defect has rarely been associated with Williams syndrome and only one necropsy case has been reported in the literature. The long term follow up of Williams syndrome associated with complete atrioventricular septal defect is reported. During a 10 year follow up period, the pressure gradient in the ascending aorta did not increase despite narrowing of the ascending aorta as identified on an aortogram.  (+info)

Follow-up study of morphology and cardiac function in rats undergoing induction of supravalvular aortic stenosis. (7/33)

OBJECTIVE: To characterize the follow-up of an experimental model of left ventricular hypertrophy (LVH) induced by supravalvular ascending aortic stenosis in young rats. METHODS: Wistar rats were submitted to thoracotomy and aortic stenosis was created by placing a clip on the ascending aorta (AoS group, n=12). Age-matched control animals underwent a sham operation (C group, n=12). Cardiac function was analysed by echocardiograms performed 6, 12, and 21 weeks after aortic banding. Myocardial morphological features and myocardial hydroxyproline concentration (HOP) were evaluated 2, 6, 12, and 21 weeks after surgery in additional animals. RESULTS: Aortic banding promoted early concentric LVH and a progressive increase in HOP. Under light microscopy, we observed myocyte hypertrophy and wall thickening of the intramural branches of the coronary arteries due to medial hypertrophy. Cardiac function was supranormal after 6 weeks (percentage of fractional shortening - EAo6: 70.3 +/- 10.8; C6: 61.3 +/- 5.4; p<0.05), and depressed in the last period. Diastolic dysfunction was detected after 12 weeks (ratio of early-to-late filling velocity - EAo12: 4.20 +/- 3.25; C12: 1.61 +/- 0.16; p<0.05). CONCLUSION: Ascending aortic stenosis promotes concentric LVH with myocardial fibrosis and minimal histological changes. According to the period of evaluation, cardiac function may be improved, normal, or depressed. The model is suitable and useful for studies on pathophysiology and treatment of the different phases of cardiac hypertrophy.  (+info)

Williams-Beuren syndrome in the Hong Kong Chinese population: retrospective study. (8/33)

OBJECTIVE: To estimate the incidence and document the clinical characteristics of Williams-Beuren syndrome in the Hong Kong Chinese population. DESIGN: Cytogenetic analysis and retrospective study. SETTING: Clinical Genetic Service, Department of Health, Hong Kong. PATIENTS: Forty-one Chinese patients with Williams-Beuren syndrome. MAIN OUTCOME MEASURES: From 1 January 1995 to 30 June 2002, fluorescence in situ hybridisation was used to confirm diagnoses in 41 cases of Williams-Beuren syndrome by detecting chromosome 7q microdeletion. Case records were reviewed, the incidence of the condition in the local population was estimated, and the main clinical characteristics were determined. RESULTS: The minimal incidence of Williams-Beuren syndrome in this locality was estimated to be approximately 1 per 23500 live births. Common dysmorphic facial features included periorbital fullness (83%), full lips (80%), a long philtrum (51%), a flat nasal bridge (41%), and abnormal teeth (37%). No patients had a stellate iris. The majority (82%) had at least one documented cardiac anomaly; among these patients, peripheral pulmonary stenosis was diagnosed in 61% and supravalvular aortic stenosis in 45%. Nearly all (93%) of the study group exhibited developmental delay. CONCLUSION: As in the West, patients with Williams-Beuren syndrome in the Hong Kong Chinese population display craniofacial dysmorphism, cardiovascular anomalies, and mental deficiency. Supravalvular aortic stenosis-the cardiac defect most commonly associated with Williams-Beuren syndrome in western countries-is less common than peripheral pulmonary stenosis in this region. Studies involving periodic cardiovascular evaluation are needed to confirm if this difference is significant.  (+info)

The lesions of the aortic root, which are supravalvular aortic stenosis and coronary ostial stenosis, in familial hypercholesterolemia were studied using two-dimensional echocardiography. The subjects were 25 heterozygotes, six homozygotes and 30 control subjects. The internal diameters of the aortic ring, the sinus of Valsalva and the supravalvular aortic ring were measured. Measurement variation due to body size was avoided by normalizing the latter two values by the diameter of the aortic ring. Four heterozygotes and all homozygotes were judged to have stenosis of the supravalvular aortic ring; none of heterozygotes and four homozygotes had stenosis of the sinus of Valsalva. In three of the four patients with stenosis of both the supravalvular aortic ring and the sinus of Valsalva, a pressure gradient was demonstrated. The degree of supravalvular aortic stenosis correlated with the serum cholesterol level but not with patient age. All homozygotes, even very young ones, had a severe aortic ...
Supravalvular aortic stenosis (SVAS) is an uncommon vascular defect causing blood flow obstruction that usually develops in the first few years of life.. This defect is a narrowing (stenosis) of the large blood vessel that carries blood from the heart to the rest of the body (the aorta), especially at major branch points.. The condition is described as supravalvular because the section of the aorta that is narrowed is located just above the valve that connects the aorta with the heart (the aortic valve).. Isolated SVAS is caused by genetic changes in the elastin gene (ELN) that can be passed from parent to child. Elastin defects are associated with connective tissue abnormalities, such joint problems, hernias, and cardiovascular disease. In children with Williams syndrome, the elastin gene is deleted along with 25-27 other genes that cause developmental delays and hormone problems. The elastin gene provides instructions for making a protein called tropoelastin. Elastin is the major component of ...

William-Beuren Syndrome is named after John C.P. Williams, a cardiologist from New Zealand, and Alois J Beuren, a German physician and cardiac researcher. Initial investigation into Williams-Beuren Syndrome came from two apparently different disorders, idiopathic infantry hypercalcemia and Supravalvular Aortic Stenosis (SVAS). With further research, these abnormalities were identified as being aspects of this same syndrome. [5] The first cases related to Williams Syndrome were in relation to Infantile Hypercalcemia. In 1957 Stapleton and colleagues studied the effects of hypercalcemia in a number of infants and noted several consistencies between them including abnormal facial features, failure to thrive, developmental delay, and systolic murmurs of the heart, all of which have now been associated with Williams Syndrome. [6] [1] J.C.P Williams was one of the first to recognise some of the clinical factors associated with this syndrome. In a study conducted in 1961 of Supravalvular Aortic ...
The phenotype is variable, likely depending upon the size of the deletion. Cardiovascular disease, primarily hypertension and large vessel stenosis, are among the most important features. The elastin arteriopathy lead to thickened arterial walls with peripheral pulmonary stenosis and supravalvular aortic stenosis. The facies is considered unique with bitemporal narrowing, a wide mouth, full lips, malocclusion, small jaw, and prominent earlobes. The teeth are small and widely spaced. Connective tissue abnormalities include joint hyperextensibility, hernias, lax skin, hypotonia, and bowel/bladder diverticulae. Small birth size is common and infants often fail to thrive but at puberty patients can experience a growth spurt. Ultimate height in adults is usually in the third centile.. Vocal cord anomalies and paralysis can result in a hoarse voice. A sensorineural hearing loss is common among adults but hyperacusis is often present in young children.. Hypercalcemia and hypercalciuria are common and ...
A cardiovascular problem called Supravalvular Aortic Stenosis (SVAS) can be associated with Williams Syndrome. SVAS is the narrowing of the large blood vessel which carries blood from the heart to the rest of the body. This problem could cause shortness of breath, chest pain and ultimately heart failure if not treated. Decreased birth weight and failure to gain weight normally is also common. There can also be digestive and urinary tract difficulties.. ...
William-Beuren Syndrome is named after John C.P. Williams, a cardiologist from New Zealand, and Alois J Beuren, a German physician and cardiac researcher. Initial investigation into Williams-Beuren Syndrome came from two apparently different disorders, idiopathic infantile hypercalcemia and Supravalvular Aortic Stenosis (SVAS) . With further research, these abnormalities were identified as being aspects of this same syndrome. [7] The first cases related to Williams Syndrome involved Idiopathic Infantile Hypercalcemia. From as early as 1952, research into infantile hypercalcemia, by Falconi et.al, found that children with this disorder had common clinical characteristics such as a short stature and a variety of congenital malformations. [8] In the years that followed many other studies were conducted in this area revealing additional correlations. For example in 1957 Stapleton and colleagues studied the effects of hypercalcemia in a number of infants and noted several consistencies between them ...
My name is Marla Levy and I owe my life to Dr. Scot Merrick, Chief of Adult Cardiothoracic Surgery at UCSF. My story begins in Southern California when I was 21 and diagnosed with a congenital heart defect: supravalvular aortic stenosis or SVAS. SVAS develops before birth and causes narrowing of the aorta, the large blood vessel that carries blood from the heart to the rest of the body. At age 27, I had my first open heart surgery. My aorta was replaced with a human valve, and when doctors couldnt get my heart to start after the procedure, I received an emergency right coronary bypass.[...] ...

The Williams-Beuren syndrome (WBS) is a sporadic congenital disorder characterized by a multisystem developmental impairment. This syndrome is caused by a microdeletion in chromosome 7q11.23 that encompasses loss of the elastin locus.. Elastin, which is part of the extracellular matrix, controls proliferation of vascular smooth muscle cells (VSMCs) and stabilizes arterial structure. Loss of elastin gene in WBS patients has been claimed to provide a biological basis for the abnormal elastic fibre properties leading to cardiovascular abnormalities like supravalvular aortic stenosis (SVAS), hypertension, arteriosclerosis and stenosis in more than 50% of WBS children.. These cardiovascular pathologies result in important consequences and neither curative nor preventive medicinal treatments exist at this time. Surgery is needed in more than half cases, while it is often leading to complications.. Minoxidil is a well-known antihypertensive drug used in adults and children. Furthermore, according to ...
Williams syndrome (WS) is a developmental disorder that affects many parts of the body. Facial features frequently include a broad forehead, short nose, and full cheeks, an appearance that has been described as elfin. Mild to moderate intellectual disability with particular problems with visual spatial tasks such as drawing and fewer problems with language are typical. Those affected often have an outgoing personality and interact readily with strangers. Problems with teeth, heart problems, especially supravalvular aortic stenosis, and periods of high blood calcium are common. Williams syndrome is caused by a genetic abnormality, specifically a deletion of about 27 genes from the long arm of one of the two chromosome 7s. Typically this occurs as a random event during the formation of the egg or sperm from which a person develops. In a small number of cases it is inherited from an affected parent in an autosomal dominant manner. The different characteristic features have been linked to the loss ...
Murmur of subvalvular aortic stenosis is unlikely to radiate to the carotids. Murmur of supravalvar aortic stenosis may radiate more to the right carotid.
For initial dilations, baseline and postdilation values for systolic pulmonary artery pressure distal to a stenosis were measured in 20 vessels (18%) and a systolic pressure gradient across the segment was measured in 12 vessels (11%). For 8 successful dilations, the initial distal pressure was 20±10 mm Hg, postdilation pressure 47±29 mm Hg (P=0.03), initial gradient (available for 5 dilations) 76±37 mm Hg, and postdilation gradient 56±37 mm Hg (P=0.09). For 12 failed dilations, baseline pulmonary pressure was 22±7 mm Hg, postdilation pressure 29±12 mm Hg (P=0.02), initial gradient (available for 7 dilations) 42±18 mm Hg, and postdilation gradient 39±18 mm Hg (P=0.25).. Baseline and postdilation measurements of RV and aortic systolic pressures were available for 25 interventional procedures. Comparisons were not made in 14 procedures because of death (3 patients), presence of a nonrestrictive ventricular septal defect (2 patients), or an unavailable pressure value (9 procedures).

A hallmark feature of Williams-Beuren Syndrome (WBS) is a generalized arteriopathy due to elastin deficiency, presenting as stenoses of medium and large arteries and leading to hypertension and other cardiovascular complications. Deletion of a functi
This gene encodes a member of the osteocalcin/matrix Gla family of proteins. The encoded vitamin K-dependent protein is secreted by chondrocytes and vascular smooth muscle cells, and functions as a physiological inhibitor of ectopic tissue calcification. Carboxylation status of the encoded protein is associated with calcification of the vasculature in human patients with cardiovascular disease and calcification of the synovial membranes in osteoarthritis patients. Mutations in this gene cause Keutel syndrome in human patients, which is characterized by abnormal cartilage calcification, peripheral pulmonary stenosis and facial hypoplasia.

LUCY R. OSBORN, 2010. Abstract: In recent years, researchers have generated a variety of mouse models in an attempt to dissect the contribution of individual genes to the complex phenotype associated with Williams syndrome (WS).. The mouse genome is easily manipulated to produce animals that are copies of humans with genetic conditions, be it with null mutations, hypomorphic mutations, point mutations, or even large deletions encompassing many genes. The existing mouse models certainly seem to implicate hemizygosity for ELN, BAZ1B, CLIP2, and GTF2IRD1 in WS, and new mice with large deletions of the WS region are helping us to understand both the additive and potential combinatorial effects of hemizygosity for specific genes. However, not all genes that are haploinsufficient in humans prove to be so in mice and the effect of genetic background can also have a significant effect on the penetrance of many phenotypes. Thus although mouse models are powerful tools, the information garnered from their ...

The aorta is the largest artery in the body. It is the main blood vessel that serves as a passageway for oxygen-filled blood to pass from the left side of the heart to be distributed throughout the entire body. Aortic stenosis may be due to the malformation of the aorta or a defect in the left ventricle.

David Dobbs has an interesting article in The New York Times Magazine about Williams syndrome; a disorder characterized by verbosity and hypersociality in concert with abstraction capacities so attenuated that most suffers are mentally retarded. The piece juggles many phenomena, from general to domain specific intelligences and the interaction between environment and genetic biases which shape the minds developmental arc ...
Williams syndrome often goes undiagnosed, which means that some people with the disorder fail to get the support and treatment they need until later in life.
About a year ago, if you remember, Self, we were just coming out of kidney failure. Williams was pretty new to us. I was overwhelmed all of the time. I turned to that woman, and I just told her what she had wanted to know. I told her about having a new baby, who was born sick, and how long it was before I could hold him. We were living away from our family, and then we took our four month old and moved to Finland for a semester abroad. I told her how my husband spent all day in school and how I was in a concrete, unfurnished apartment sitting on a sleeping bag with a baby who screamed all day and all night, and clawed at his face until he bled because something was wrong and we didnt know what. I told her that as soon as we hit America we took him to a doctor where they did test after test after test, and finally it was determined that his severe heart problems, among other things, pointed toward a strange thing called WILLIAMS SYNDROME. And how after even more testing, it was determined that ...

Author Summary A fundamental question in current biomedical research is to establish a link between genomic variation and phenotypic differences, which encompasses both the seemingly neutral diversity, as well as the pathological variation that causes or predisposes to disease. Once the primary genetic cause(s) of a disease or phenotype has been identified, we need to understand the biochemical consequences of such variants that eventually lead to increased disease risk. Such phenotypic effects of genetic differences are supposedly brought about by changes in expression levels, either of the genes affected by the genetic change or indirectly through position effects. Thus, transcriptome analyses seem appropriate proxies to study the consequences of structural variation, such as the 7q11.23 deletion present in individuals with Williams-Beuren syndrome (WBS). Here, we present an approach that takes experimental data into account instead of relying solely on functional annotation, following the rationale
Aortic Valve Stenosis: A pathological constriction that can occur above (supravalvular stenosis), below (subvalvular stenosis), or at the AORTIC VALVE. It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA.

Anthrozoos, 29 (1), 35-46.. This exploratory study investigated the effect of visiting therapy dogs on college student perceived and physiological stress the week prior to final exams. Students (n=78) were randomly assigned to order of a therapy dog intervention and attention-control condition, each 15 minutes long. Students completed the Perceived Stress Scale (PSS), a stress visual analog scale (SVAS), and provided saliva for measuring nerve growth factor (sNGF) and alpha amylase (sAA) prior to randomization. Saliva samples and SVAS were again collected after each condition. There was no effect of group order on demographics, PSS, or initial SVAS. Repeated measures models were used to analyze the complete data sets of 57 students. There were no significant differences in sAA between or within students ...

1. Renin release from an intact, innervated kidney and from the contralateral denervated kidney was measured before and during a period of suprarenal aortic stenosis.. 2. Aortic stenosis of 10 min duration reduced renal perfusion pressure to 50 mmHg and increased renin release from both kidneys, but the response from the innervated kidney was greater.. 3. A study of the time-course of the response during 30 min of aortic stenosis showed that the difference in rate of renin release between the innervated and the denervated kidney is greatest during the first few minutes of aortic stenosis. ...

The 2012 ESC/EACTS guidelines for AS recommend replacement for Class I patients, i.e. those with severe AS and symptoms. TAVI is indicated in patients with severe symptomatic AS who are not suitable for AVR as assessed by a heart team and should be considered in high risk patients who may still be suitable for surgery, but in whom TAVI is favored by a heart team based on the individual risk profile.2 The 2008 ACC/AHA guidelines recommend that AVR should be performed in virtually all symptomatic patients with severe AS. Both guidelines stress that age is not a contraindication to surgery.2,3. Download Aortic Stenosis Brochure. ...
