The standard approach is transthoracic.Calcinosis: Pathologic deposition of calcium salts in tissues.Catheterization: Use or insertion of a tubular device into a duct, blood vessel, hollow organ, or body cavity for injecting or withdrawing fluids for diagnostic or therapeutic purposes. It differs from INTUBATION in that the tube here is used to restore or maintain patency in obstructions.Constriction, Pathologic: The condition of an anatomical structure's being constricted beyond normal dimensions.Pyloric Stenosis: Narrowing of the pyloric canal with varied etiology. A common form is due to muscle hypertrophy (PYLORIC STENOSIS, HYPERTROPHIC) seen in infants.Severity of Illness Index: Levels within a diagnostic group which are established by various measurement criteria applied to the seriousness of a patient's disorder.Blood Vessels: Any of the tubular vessels conveying the blood (arteries, arterioles, capillaries, venules, and veins).Syphilis, Cardiovascular: Cardiovascular manifestations of SYPHILIS, an infection of TREPONEMA PALLIDUM.

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 ...

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.. ...

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). Mean RV ...

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.

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.

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 ...

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.

Keutel syndrome (KS) is a rare autosomal recessive genetic disorder characterized by abnormal diffuse cartilage calcification, hypoplasia of the mid-face, peripheral pulmonary stenosis, hearing loss, short distal phalanges (tips) of the fingers and mild mental retardation. Individuals with KS often present with peripheral pulmonary stenosis, brachytelephalangism, sloping forehead, midface hypoplasia, and receding chin. It is associated with abnormalities in the gene coding for matrix gla protein (MGP). Being an autosomal recessive disorder, it may be inherited from two unaffected, abnormal MGP-carrying parents. Thus, people who inherit two affected MGP genes will likely inherit KS. It was first identified in 1972 as a novel rare genetic disorder sharing similar symptoms with chondrodysplasia punctata. Multiple forms of chondrodysplasia punctata share symptoms consistent with KS including abnormal cartilage calcification, forceful respiration, brachytelephalangism, hypotonia, psychomotor delay, ...
Aortic stenosis means that your child has a heart valve that is too narrow or is blocked. The aortic valve is 1 of 4 heart valves that keep blood flowing through the heart. The valves make sure blood flows in only 1 direction. The aortic valve keeps blood flowing from the left ventricle to the aorta. Your child may be born with aortic stenosis (congenital). Or it may happen later (acquired). It occurs more often in boys than in girls.. A normal aortic valve has 3 cusps (leaflets) that act as a 1-way door. With aortic stenosis, the valve doesnt work as it should or has an abnormal number of leaflets that dont work correctly. That makes it harder for the leaflets to open and let blood flow from the left ventricle to the aorta.. Aortic stenosis may be mild, moderate, or severe. It depends on how much of the blood is blocked. The condition may get worse over time. It may also occur with other heart problems or conditions.. Moderate to severe aortic stenosis may affect the heart and blood vessels ...
The aorta, the bodys largest blood vessel, starts from the left ventricle of the heart and carries oxygen-rich blood to the body. Blood flows from the left ventricle into the aorta through the aortic valve, one of the four valves in the heart.. In aortic stenosis, the aortic valve is narrow. This decreases the amount of blood flowing into the aorta and out to the rest of the body. Aortic stenosis is most common in adults over 50, but can be present at birth (congenital).. Aortic stenosis makes the heart work harder to pump blood to the body. Over time, this added stress can weaken the heart and lead to life-threatening heart problems.. Aortic stenosis can be identified before birth, allowing babies born with severe cases to be treated right away. Babies with aortic stenosis can have trouble gaining weight, problems with feeding, and serious breathing problems that develop soon after birth. Older children also may have a heart murmur. These children may be sent for an echocardiogram, a type of ...

ndividuals with Williams syndrome typically show relatively poor visuospatial abilities in comparison to stronger verbal skills. However, individuals level of performance is not consistent across all visuospatial tasks. The studies assessing visuospatial functioning in Williams syndrome are critically reviewed, to provide a clear pattern of the relative difficulty of these tasks. This prompts a possible explanation of the variability in performance seen, which focuses on the processing demands of some of these tasks. Individuals with Williams syndrome show an atypical processing style on tests of construction, which does not affect tests of perception.. ...

Patients in the verum group will receive fluvastatin in a starting dose of 40 mg per day. The dose should be increased up to 80 mg per day. The treatment should be continued until the study end (24 months). Follow up investigations will be performed after 6, 12, and 18 months. After 24 months the final investigations will be performed ...
FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene contains five GTF2I-like repeats and each repeat possesses a potential helix-loop-helix (HLH) motif. It may have the ability to interact with other HLH-proteins and function as a transcription factor or as a positive transcriptional regulator under the control of Retinoblastoma protein. This gene plays a role in craniofacial and cognitive development and mutations have been associated with Williams-Beuren syndrome, a multisystem developmental disorder caused by deletion of multiple genes at 7q11.23. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2010 ...

This study was undertaken to assess the contribution of Doppler echocardiography to the quantification of aortic valve regurgitation. Ultrasound examination was performed by recording aortic arch blood flow from the suprasternal notch. A non-invasive index of valve regurgitation was obtained by calculating the ratio between the maximal amplitude of forward flow during systole and the amplitude of retrograde flow during diastole measured at the onset of the R wave of the electrocardiogram. This index was compared with semiquantitative data derived from supravalvular aortography in 93 patients. In pure aortic regurgitation (67 patients) the results showed a high correlation coefficient between Doppler and angiographic estimates. In cases of associated aortic valve stenosis there were problems in the accurate estimation of systolic blood flow which led to global overestimation in general of the degree of regurgitation and considerable lack of precision in individual patients. But in general Doppler ...
As the aortic valve narrows, the left ventricle has to work harder to pump blood out through the valve. To do this extra work, the muscles in the ventricle walls become thicker. This can lead to chest pain. As the pressure continues to rise, blood may back up into the lungs. Severe aortic stenosis can limit the amount of blood that reaches the brain and the rest of the body.. Aortic stenosis may be present from birth (congenital), but most often it develops later in life. Children with aortic stenosis may have other conditions present from birth.. Aortic stenosis mainly occurs due to the buildup of calcium deposits that narrow the valve. This is called calcific aortic stenosis. The problem mostly affects older people. Calcium buildup of the valve happens sooner in people who are born with abnormal aortic or bicuspid valves. In rare cases, calcium buildup can develop more quickly when a person has received chest radiation (such as for cancer treatment).. Another cause is rheumatic fever. This ...
Williams syndrome is characterized by a wide spectrum of symptoms and physical features that vary greatly in range and severity, even among affected family members. Individuals with Williams syndrome will not have all the symptoms listed below. Some affected individuals do not have heart (cardiac) abnormalities; others may not have elevated levels of calcium in the body (hypercalcemia). In addition, the severity of these symptoms often varies greatly from case to case.. Some children with Williams syndrome may have a low birth weight, feed poorly, and fail to gain weight and grow at the expected rate (failure to thrive). Symptoms such as vomiting, gagging, diarrhea, and constipation are common during infancy. Some affected infants may have elevated levels of calcium in their blood (hypercalcemia), leading to loss of appetite, irritability, confusion, weakness, easy fatigability, and/or abdominal and muscle pain. Calcium levels usually return to normal around the age of 12 months. However, in ...
Pathologists have long observed that early stages of human vascular calcification occur along the edges and frayed ends of elastin fibers.52 As noted earlier, elastin haploinsufficiency reduces the vascular calcification associated with MGP deficiency in mice.39 The authors interpreted this finding to mean that MGP either protects mineralization initiation sites on elastin or alters extracellular matrix. These findings suggest that, in the context of MGP insufficiency, elastin calcification is metabolic in origin and that metabolic mineralization may lead to osteochondrogenic differentiation. Results showed a reduction in calcification and an increase in life span.39 The potential importance of elastin in other forms of vascular calcification is supported by its role as the target of calcification in the hereditary human disease, pseudoxanthoma elasticum (PXE), described below.. Clues about the role of elastin in metabolic vascular calcification come from the hereditary human disorder, PXE, ...

Phase refers to angular position of a proton`s spinning vector. For PC imaging not the magnitude of the protons` spinning vector but their phase (angle) data are used. A bipolar gradient pulse pair (a pair of gradients with same field strength but opposite directions) is applied in the direction of flow. The phase difference induced by the first bipolar gradient in the static tissue is completely reversed by the second gradient (which is of same strength but opposite direction). Therefore protons in the static tissue have a net phase of zero after the bipolar gradient is applied. However since protons of flowing blood are moving along the gradient they are exposed to different gradient strengths during acquisition and their net phase is not zero. The net phase acquired by the flowing protons is proportional to their velocity and PC CMR imaging uses this principle to derive velocity of flow.. ...

Married to my college sweetheart Shawn for 14 years, we have six children - Jamie (11), Clare (9), Simon (7), Violet (5), Eliza (3), and Cecily (1). Our second child, Clare, was born with a rare genetic condition, Williams syndrome, severe congenital heart defects (pulmonary stenosis and aortic stenosis), a Chiari Malformation, mid-aortic syndrome, and kidney issues. She has undergone one open heart surgery and ten cardiac catheterizations to repair her cardiac and vascular defects and has also undergone a frenulectomy (tongue-tie release) and an angio-embolization of her radial artery to repair an A-V fistula and aneurysm. On May 1, she had her longest surgery yet - a bypass graft of her abdominal aorta, a bypass graft of her SMA vessel, and a kidney re-transplant (kidneys transplanted elsewhere in her body). I began this blog when Clare was an infant to chronicle our life on this new journey into Williams syndrome and raising a child with special needs and a chronic heart condition. As our ...
Regular checkups by a provider may be all that is needed if your symptoms are not severe. The provider should ask about your health history, do a physical exam, and perform an echocardiogram.. People with severe aortic stenosis may be told not to play competitive sports, even if they have no symptoms. If symptoms do occur, strenuous activity must often be limited.. Medicines are used to treat symptoms of heart failure or abnormal heart rhythms (most commonly atrial fibrillation). These include diuretics (water pills), nitrates, and beta-blockers. High blood pressure should also be treated. If aortic stenosis is severe, this treatment must be done carefully so blood pressure does not drop too far.. In the past, most people with heart valve problems were given antibiotics before dental work or a procedure such as colonoscopy. The antibiotics were given to prevent an infection of the damaged heart. However, antibiotics are now used much less often before dental work and other procedures. Check with ...
