A bluish or purplish discoloration of the skin and mucous membranes due to an increase in the amount of deoxygenated hemoglobin in the blood or a structural defect in the hemoglobin molecule.
The presence of methemoglobin in the blood, resulting in cyanosis. A small amount of methemoglobin is present in the blood normally, but injury or toxic agents convert a larger proportion of hemoglobin into methemoglobin, which does not function reversibly as an oxygen carrier. Methemoglobinemia may be due to a defect in the enzyme NADH methemoglobin reductase (an autosomal recessive trait) or to an abnormality in hemoglobin M (an autosomal dominant trait). (Dorland, 27th ed)
Symmetrical osteitis of the four limbs, chiefly localized to the phalanges and the terminal epiphyses of the long bones of the forearm and leg, sometimes extending to the proximal ends of the limbs and the flat bones, and accompanied by dorsal kyphosis and joint involvement. It is often secondary to chronic conditions of the lungs and heart. (Dorland, 27th ed)
Diversion of the flow of blood from the entrance to the right atrium directly to the pulmonary arteries, avoiding the right atrium and right ventricle (Dorland, 28th ed). This a permanent procedure often performed to bypass a congenitally deformed right atrium or right ventricle.
Developmental abnormalities involving structures of the heart. These defects are present at birth but may be discovered later in life.
A congenital heart defect characterized by downward or apical displacement of the TRICUSPID VALVE, usually with the septal and posterior leaflets being attached to the wall of the RIGHT VENTRICLE. It is characterized by a huge RIGHT ATRIUM and a small and less effective right ventricle.
Abnormal formation of blood vessels that shunt arterial blood directly into veins without passing through the CAPILLARIES. They usually are crooked, dilated, and with thick vessel walls. A common type is the congenital arteriovenous fistula. The lack of blood flow and oxygen in the capillaries can lead to tissue damage in the affected areas.
A combination of congenital heart defects consisting of four key features including VENTRICULAR SEPTAL DEFECTS; PULMONARY STENOSIS; RIGHT VENTRICULAR HYPERTROPHY; and a dextro-positioned AORTA. In this condition, blood from both ventricles (oxygen-rich and oxygen-poor) is pumped into the body often causing CYANOSIS.
Abnormal thoracoabdominal VISCERA arrangement (visceral heterotaxy) or malformation that involves additional CONGENITAL HEART DEFECTS (e.g., heart isomerism; DEXTROCARDIA) and/or abnormal SPLEEN (e.g., asplenia and polysplenia). Irregularities with the central nervous system, the skeleton and urinary tract are often associated with the syndrome.
A procedure in which total right atrial or total caval blood flow is channeled directly into the pulmonary artery or into a small right ventricle that serves only as a conduit. The principal congenital malformations for which this operation is useful are TRICUSPID ATRESIA and single ventricle with pulmonary stenosis.
The short wide vessel arising from the conus arteriosus of the right ventricle and conveying unaerated blood to the lungs.
A compound consisting of dark green crystals or crystalline powder, having a bronze-like luster. Solutions in water or alcohol have a deep blue color. Methylene blue is used as a bacteriologic stain and as an indicator. It inhibits GUANYLATE CYCLASE, and has been used to treat cyanide poisoning and to lower levels of METHEMOGLOBIN.
The veins that return the oxygenated blood from the lungs to the left atrium of the heart.
The venous trunk which returns blood from the head, neck, upper extremities and chest.
A surface anesthetic that acts by preventing transmission of impulses along NERVE FIBERS and at NERVE ENDINGS.
An infant during the first month after birth.
A FLAVOPROTEIN oxidoreductase that occurs both as a soluble enzyme and a membrane-bound enzyme due to ALTERNATIVE SPLICING of a single mRNA. The soluble form is present mainly in ERYTHROCYTES and is involved in the reduction of METHEMOGLOBIN. The membrane-bound form of the enzyme is found primarily in the ENDOPLASMIC RETICULUM and outer mitochondrial membrane, where it participates in the desaturation of FATTY ACIDS; CHOLESTEROL biosynthesis and drug metabolism. A deficiency in the enzyme can result in METHEMOGLOBINEMIA.
A syndrome characterized by the clinical triad of advanced chronic liver disease, pulmonary vascular dilatations, and reduced arterial oxygenation (HYPOXEMIA) in the absence of intrinsic cardiopulmonary disease. This syndrome is common in the patients with LIVER CIRRHOSIS or portal hypertension (HYPERTENSION, PORTAL).
The pathologic narrowing of the orifice of the PULMONARY VALVE. This lesion restricts blood outflow from the RIGHT VENTRICLE to the PULMONARY ARTERY. When the trileaflet valve is fused into an imperforate membrane, the blockage is complete.
Absence of the orifice between the RIGHT ATRIUM and RIGHT VENTRICLE, with the presence of an atrial defect through which all the systemic venous return reaches the left heart. As a result, there is left ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR) because the right ventricle is absent or not functional.
Developmental abnormalities in any portion of the ATRIAL SEPTUM resulting in abnormal communications between the two upper chambers of the heart. Classification of atrial septal defects is based on location of the communication and types of incomplete fusion of atrial septa with the ENDOCARDIAL CUSHIONS in the fetal heart. They include ostium primum, ostium secundum, sinus venosus, and coronary sinus defects.
Radiography of blood vessels after injection of a contrast medium.
An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES. An A-V fistula usually leads to the formation of a dilated sac-like connection, arteriovenous aneurysm. The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.
The determination of oxygen-hemoglobin saturation of blood either by withdrawing a sample and passing it through a classical photoelectric oximeter or by electrodes attached to some translucent part of the body like finger, earlobe, or skin fold. It includes non-invasive oxygen monitoring by pulse oximetry.
A congenital cardiovascular malformation in which the AORTA arises entirely from the RIGHT VENTRICLE, and the PULMONARY ARTERY arises from the LEFT VENTRICLE. Consequently, the pulmonary and the systemic circulations are parallel and not sequential, so that the venous return from the peripheral circulation is re-circulated by the right ventricle via aorta to the systemic circulation without being oxygenated in the lungs. This is a potentially lethal form of heart disease in newborns and infants.
Developmental abnormalities in any portion of the VENTRICULAR SEPTUM resulting in abnormal communications between the two lower chambers of the heart. Classification of ventricular septal defects is based on location of the communication, such as perimembranous, inlet, outlet (infundibular), central muscular, marginal muscular, or apical muscular defect.

Decreased left ventricular filling pressure 8 months after corrective surgery in a 55-year-old man with tetralogy of Fallot: adaptation for increased preload. (1/188)

A 55-year-old man with tetralogy of Fallot underwent corrective surgery. Left ventricular filling pressure increased markedly with increased left ventricular volume one month after surgery, then decreased over the next 7 months, presumably due to increased left ventricular compliance.  (+info)

Left ventricle to pulmonary artery conduit in treatment of transposition of great arteries, restrictive ventricular septal defect, and acquired pulmonary atresia. (2/188)

Progressive cyanosis after banding of the pulmonary artery in infancy occurred in a child with transposition of the great arteries and a ventricular septal defect, and a Blalock-Taussig shunt operation had to be performed. At the time of correction a segment of pulmonary artery between the left ventricle and the band was found to be completely occluded so that continuity between the left ventricle and the pulmonary artery could not be restored. A Rastelli type of operation was not feasible as the ventricular septal defect was sited low in the muscular septum. Therefore, in addition to Mustard's operation, a Dacron conduit was inserted from the left ventricle to the main pulmonary artery to relieve the obstruction. Postoperative cardiac catheterization with angiocardiography indicated a satisfactory haemodynamic result. The patient remains well 11 months after the operation. This operation, a left ventricle to pulmonary artery conduit, may be used as an alternative procedure in patients with transposition of the great arteries, intact interventricular septum, and obstruction to the left ventricular outflow, if the obstruction cannot be adequately relieved.  (+info)

The myocardial profile of the cytosolic isozymes of creatine kinase is apparently not related to cyanosis in congenital heart disease. (3/188)

BACKGROUND: CKMB, the cardiac-specific heterodimer of cytosolic creatine-kinase (CK), is developmentally and physiologically regulated, tissue hypoxia being a proposed regulator. In patients with cyanotic heart disease the myocardium is perfused with partially saturated blood. We questioned whether the myocardium of cyanotic subjects contains higher proportions of CKMB. MATERIALS AND METHODS: CK activity, the distribution of cytosolic CK isozymes, activity of lactic dehydrogenase (LDH), and tissue protein content were determined in obstructive tissues removed at corrective surgery of patients with congenital heart defects. Cyanotic (n = 13) and acyanotic (n = 12) subjects were compared. RESULTS: In cyanotic and acyanotic patients, CK activity was 8.4 +/- 0.6 and 7.6 +/- 0.6 IU/mg protein and the proportion of CKMB was 21 +/- 1.4 and 22 +/- 2. 0% (mean +/- S.E.M), respectively. In the two groups of patients, the activity related to the B subunit corresponded to the steady-state level of the CKBmRNA. The tissue content of protein and the activities of CK and LDH were similar in cyanotic and acyanotic subjects and increased with the age. CONCLUSIONS: The lack of difference in CKMB distribution between the cyanotic and acyanotic patients may either indicate that hypooxygenation is not a regulator of CK isozyme expression, or may be attributed to the already high proportion of this isozyme in hypertrophied, obstructive tissues. Recruitment of additional CKMB, in the cyanotic hearts, may thus not be required.  (+info)

Controlled study of preschool development after surgery for congenital heart disease. (4/188)

AIM: Research into intellectual impairment among children with congenital heart disease has focused mainly on older children. This study was designed to determine whether previous findings are applicable to preschool children. METHODS: Three groups of children under 31/2 years old were assessed immediately before treatment and 12 months later: a group with congenital heart disease awaiting surgery, another awaiting bone marrow transplantation, and a healthy comparison group. RESULTS: Although the means of the three groups were within the normal range, preoperatively the cardiac and transplant groups showed deficits compared with the healthy controls. Postoperatively, continuing developmental deficits were significant only in the children with cyanotic lesions. CONCLUSIONS: Conclusions about intellectual development in older children with congenital heart disease do not apply to preschool children. Before corrective surgery, chronic illness itself appears to be the predominant influence on development. Postoperatively, cyanotic and acyanotic lesions are associated with different short term outcomes.  (+info)

Malnutrition and growth failure in cyanotic and acyanotic congenital heart disease with and without pulmonary hypertension. (5/188)

AIM: To investigate the effect of several types of congenital heart disease (CHD) on nutrition and growth. PATIENTS AND METHODS: The prevalence of malnutrition and growth failure was investigated in 89 patients with CHD aged 1-45 months. They were grouped according to cardiac diagnosis: group aP (n = 26), acyanotic patients with pulmonary hypertension; group ap (n = 5), acyanotic patients without pulmonary hypertension; group cp (n = 42), cyanotic patients without pulmonary hypertension; and group cP (n = 16), cyanotic patients with pulmonary hypertension. Information on socioeconomic level, parental education status, birth weight and nutrition history, number of siblings, and the timing, quality, and quantity of nutrients ingested during weaning period and at the time of the examination were obtained through interviews with parents. RESULTS: There was no significant difference between groups in terms of parental education status, socioeconomic level, duration of breast feeding, and number of siblings (p > 0.05). Group cP patients ingested fewer nutrients for their age compared to other groups. 37 of the 89 patients were below the 5th centile for both weight and length, and 58 of 89 patients were below the 5th centile for weight. Mild or borderline malnutrition was more common in group aP patients. Most group cp patients were in normal nutritional state, and stunting was more common than wasting. Both moderate to severe malnutrition and failure to thrive were more common in group cP patients. CONCLUSION: Patients with CHD are prone to malnutrition and growth failure. Pulmonary hypertension appears to be the most important factor, and cyanotic patients with pulmonary hypertension are the ones most severely affected. This study shows the additive effects of hypoxia and pulmonary hypertension on nutrition and growth of children with CHD.  (+info)

Use of self expanding stents in stenotic aortopulmonary shunts in adults with complex cyanotic heart disease. (6/188)

OBJECTIVE: To describe the use of self expanding stents in treating long segment stenosis of aortopulmonary shunts (APS) in adults. DESIGN: Clinical records, catheterisation data, cineangiograms, and operation notes of four consecutive patients undergoing stent implantation since December 1994 were studied retrospectively. SETTING: A tertiary referral centre for cardiac disease. SUBJECTS: Four patients underwent cardiac catheterisation because of clinical deterioration. Their age ranged between 23 and 32 years. The underlying diagnosis was complex cyanotic heart disease in all. Three had a stenotic interposition graft, and one had a classic Blalock shunt. RESULTS: There was one technical failure owing to migration of the stent distal to an ostial stenosis. The ability index, resting oxygen saturation, and exercise tolerance improved in the remainder. Their medium term results have been excellent. CONCLUSIONS: This technique may further palliate adult patients with complex congenital heart disease, though the long term patency of stents is unknown.  (+info)

A case of methemoglobinemia after ingestion of an aphrodisiac, later proven as dapsone. (7/188)

Methemoglobin (MetHb) is an oxidation product of hemoglobin in which the sixth coordination position of ferric iron is bound to a water molecule or to a hydroxyl group. The most common cause of acquired MetHb-emia is accidental poisoning which usually is the result of ingestion of water containing nitrates or food containing nitrite, and sometimes the inhalation or ingestion of butyl or amyl nitrite used as an aphrodisiac. We herein report a case of MetHb-emia after ingestion of an aphrodisiac, later identified as dapsone by gas chromatograph/mass selective detector (GC/MSD). A 24-year old male was admitted due to cyanosis after ingestion of a drug purchased as an aphrodisiac. On arterial blood gas analysis, pH was 7.32, PaCO2 26.8 mmHg, PaO2 75.6 mmHg, and bicarbonate 13.9 mmol/L. Initial pulse oxymetry was 89%. With 3 liter of nasal oxygen supplement, oxygen saturation was increased to 90-92%, but cyanosis did not disappear. Despite continuous supplement of oxygen, cyanosis was not improved. On the fifth hospital day, MetHb was 24.9%. Methylene blue was administered (2 mg/kg intravenously) and the patient rapidly improved. We proved the composition of aphrodisiac as dapsone by the method of GC/MSD.  (+info)

Occlusion of azygos vein via direct percutaneous puncture of innominate vein following cavopulmonary anastomosis. (8/188)

A 2-year-10-month-old boy was diagnosed with a complex congenital heart disease: right atrial isomerism, left superior vena cava (LSVC), complete atrioventricular septal defect, secundum type atrial septal defect, transposition of the great arteries with pulmonary atresia, patent ductus arteriosus, absence of a right superior vena cava (RSVC), and dextrocardia. He had received a left Blalock-Taussig (BT) shunt at the age of 3 months and a left bidirectional Glenn shunt one year after BT shunt. Progressive cyanosis was noted after the second operation and cardiac catheterization showed a functional Glenn shunt with an engorged azygos vein, which was inadvertently skipped for ligation. Because of the absence of RSVC, transcatheter occlusion of the azygos vein was performed successfully via direct puncture of the innominate vein.  (+info)

Acyanotic congenital heart disease comprises numerous aetiologies, which can be divided into those with increased pulmonary vascularity (pulmonary plethora) and those with normal vascularity: increased pulmonary vascularity ventricular septal d...
Some congenital heart defects cause cyanosis, or low oxygen levels in the blood, which can give children a bluish appearance. In many cases, the cyanotic heart defect is repaired in childhood, and oxygen levels return to normal. Sometimes, a complete repair isnt possible and the cyanosis is present for life.. Cyanotic Heart Disease is a heart defect, or group of heart defects that are present at birth. Under normal circumstances, an infants blood contains ample oxygen that flows throughout the body. When cyanosis is present, blood flows abnormally (called right-to-left shunt), resulting in too little oxygen in the blood flow and causing the childs skin to take on a bluish appearance. This bluish discoloration is most often seen on the fingers, lips, and toes. Several types of congenital heart disease may cause cyanosis, including:. - Pulmonary Valve Atresia. - Tetralogy of Fallot. - Tricuspid Atresia. - Hypoplatic Left Heart Syndrome. - Truncus Arteriosus. - Total Anomalous Pulmonary Venous ...
TY - JOUR. T1 - Central aorta-pulmonary artery shunts in neonates with complex cyanotic congenital heart disease. AU - Barragry, T. P.. AU - Ring, W. S.. AU - Blatchford, J. W.. AU - Foker, J. E.. PY - 1987. Y1 - 1987. N2 - Methods of palliating critical pulmonary oligemia in neonates with complex cyanotic congenital heart disease continue to evolve. Pulmonary artery distortion and other complications of the use of native vessels to increase pulmonary blood flow has led to the more frequent use of polytetrafluorethylene shunts either in a central position or as a modified Blalock-Taussig shunt. Central aorta-pulmonary artery shunts have largely fallen into disfavor because of previously reported unacceptably high incidences of complications such as shunt thrombosis, congestive heart failure, and pulmonary artery distortion. This report details our experience palliating 23 neonates with pulmonary atresia or severe pulmonary stenosis by placing central aorta-pulmonary artery shunts utilizing a ...
A 54-year-old man was admitted with a 4-year history of recurrent urinary tract infections. He had a history of osteoarthritis of the left hip and benign prostatic enlargement. Physical examination showed clubbing with cyanosis (figure), and a grade 4/6 systolic murmur throughout the praecordium. Electrocardiogram showed right ventricular hypertrophy with features of pressure overload (appendix). His haemoglobin was raised at 200 g/L, with a haematocrit of 0·53. A CT scan of the genitourinary system showed multiple large urinary bladder stones (figure), urinary bladder wall thickening, trabeculations and diverticulae, and bilateral hydroureters and hydronephrosis.. ...
It is well known that malnutrition accompanies and contributes to morbidity in CHD. Controversy exists regarding the relative roles of low caloric intake, type of cardiac lesion, malabsorption, and hypermetabolism.1-4 Patients with CHD and cyanosis, pulmonary hypertension, and congestive heart failure appear to have an increased prevalence of growth failure and malnutrition.1 4-6 Optimising nutritional status improves surgical outcome and contributes to reduced morbidity. In a large survey of 890 children with various CHD, 55% were below the 16th centile for height, 52% were below the 16th centile for weight, and 27% were below the 3rd centile for both length and weight.7 In our study malnutrition appears to be more prevalent and more severe, as 65% of the children were below the 5th centile for weight, and 41% were below the 5th centile for both weight and height. Fifty six of 89 patients (63%) were underweight for their length. This might have been because most of the patients referred to our ...

Editor,-I welcome Thornes editorial1 reiterating the pitfalls of overzealous venesection in adults with cyanotic congenital heart disease. As she states there is now a body of opinion highlighting the detrimental effects of inappropriate venesection. The evidence these conclusions are based on, however, is sparse and retrospective. This will unfortunately be a feature of a relatively new field such as adult congenital disease practice until multicentred collaboration and prospective studies are planned. Despite these limitations the work we have at present points towards the principles expounded by Thorne. A recent paper by Ammash and Warnes,2 not mentioned in Thornes editorial, provides further evidence regarding the lack of association between stroke and a high haematocrit. This study of cyanotic patients followed for 3135 patient-years did not identify an association between red cell mass and stroke. Of particular interest was the finding that iron deficiency and recurrent venesection were ...
A number of widely held misconceptions result in inappropriate venesection. First, that it is performed to prevent the risk of stroke, therefore secondly, that it should be done routinely to keep the haematocrit , 65% regardless of symptoms, and thirdly that volume replacement is not required.. The idea that hyperviscosity is a risk factor for cerebral arterial thrombosis in adults with cyanotic heart disease has arisen from studies in other patient groups. This, along with the observation that symptoms of reduced cerebral blood flow secondary to hyperviscosity are transiently relieved by venesection, has led to the widespread belief that haematocrit levels in patients with cyanotic heart disease should not be allowed to rise too high.. The risk of vascular occlusion in patients with primary polycythaemia rubra vera relates both to degree of erythrocytosis and to thrombocytosis, and treatment guidelines in this disease recommend venesection to maintain a haematocrit ⩽ 45.2 6Haematologists ...
Semantic Scholar extracted view of Hematogenous brain abscess in cyanotic congenital heart disease. Report of three cases, with complete transposition of the great vessels. by R M Shahler et al.
Cyanosis: is another common symptom which concern children with particular types of heart diseases that are defined cyanotic. The cyanosis consist in blue-purple color of skin and mucous membrane (lips, tongue) due to the fact that blood that t reached the organs and tissues through the arteries is not sufficiently oxygenated. Blood adequately oxygenated has a red color where as the less is the content in oxygen the more the color becomes blue. There are two major causes of cyanosis: heart causes in which venous blood because of a cardiac defect by-passes the lungs and goes down the aorta and the arteries without being oxygenated; lung causes in which the lung functions are impaired. There are numerous congenital cyanotic heart diseases the most frequent of which are Tetralogy of Fallot, complete Transposition of the Great Arteries and pulmonary atresia. Cyanosis determines a lack of oxygen for organs and tissues with the consequences that the child will have a reduce tolerance to exercise, ...
Congenital - a disease or physical abnormality present from birth. Cyanosis - Clinical term referring to a blue coloration of the skin and mucous membranes due to the presence of deoxygenated hemoglobin. One cause of cyanosis is cyanotic heart disease.

Whether phlebotomy is efficacious in polycythemic patients with cor pulmonale is controversial23. Adults with cyanotic congenital heart disease and erythrocytosis are frequently phlebotomized and occasionally anticoagulated. The rationale for phlebotomy assumes an inherent increase in the risk of cerebral arterial thrombotic stroke, a risk that has not withstood scrutiny in a study of 112 adults with cyanotic congenital heart disease observed for a total of 748 patients years24.. 1998: An article in Heart Journal stated that: Polycythemic cyanotic patients experience symptoms caused by the detrimental effects of hyperviscosity on tissue oxygen delivery rather than by a high hematocrit itself. There is no evidence that venesection alone (without myelosuppressive treatment) reduces the risk of thrombosis in polycythemia rubra vera; on the contrary, patients who undergo frequent venesection have a higher incidence of vascular occlusion. The risk of cerebral infarction in cyanotic children ...
Congenital heart diseases (CHDs) are the most common congenital defects that child is having at birth.. Pediatric cardiac interventions has been increased dramatically both in number as well as type of procedures performed. CHDs are classified according to their physiological characteristics. Most common is left-to-right shunt CHDs (e. g. ASD, VSD, PDA); others are right-to-left shunt/obstructive lesions (pulmonary stenosis, right ventricular outflow tract obstruction); left heart stenotic diseases (aortic stenosis, coarctation of the aorta).. Child may have pink colour (acyanotic congenital heart defects) or may have bluish discolouration of lips and fingers (cyanotic congenital heart defects).. Majority of acyanotic CHDs can be managed without open heart surgery i.e. by doing non-surgical closure of holes in heart etc (pediatric cardiac interventions). Few cyanotic CHDs can also be palliated in cath lab by cardiac interventions.. Cardiac interventions are done in cath lab under fluoroscopic ...

with the aim of determining, in children with cyanotic congenital heart disease, which of three different pulse oximeter sensors is the most accurate at lower blood oxygen saturation levels, when compared to the gold standard of arterial blood gas analysis with CO-oximetry. The three sensors were Masimo SET® with LNCS® sensor (Masimo Standard), Masimo SET® with Blue sensor (Masimo Blue), and Nellcor™ N-600 with MAX-I sensor (Nellcor). In the study, published in the journal Pediatric Critical Care Medicine, Dr. Harris and colleagues collected data from 50 infants and children weighing 3-20 kg with baseline saturations under 90% (measured by pulse oximetry at the time of clinical assessment) undergoing surgical or catheterization procedures. Following standard care monitoring, which included placement of the Masimo Standard sensor, the Masimo Blue and Nellcor MAX-I sensors were placed on a thumb or great toe, or alternatively on a finger.

The treatment of choice for most congenital heart diseases is surgery to repair the defect. There are many types of surgery, depending on the kind of birth defect. Surgery may be needed soon after birth, or it may be delayed for months or even years.. Your child may need to take water pills (diuretics) and other heart medicines before or after surgery. Be sure to follow the correct dosage. Regular follow-up with the doctor is important.. Many children who have had heart surgery must take antibiotics before, and sometimes after having any dental work or other medical procedures. Make sure you have clear instructions from your childs heart doctor. Ask your childs doctor before getting any immunizations. Most children can follow the recommended guidelines for childhood vaccinations. ...
There are many types of congenital heart defects. If the defect lowers the amount of oxygen in the body, it is called cyanotic. If the defect doesnt affect oxygen in the body, it is called acyanotic. What are cyanotic heart defects?. Cyanotic heart defects are defects that allow oxygen-rich blood and oxygen-poor blood to mix.. In cyanotic heart defects, less oxygen-rich blood reaches the tissues of the body. This results in the development of a bluish tint (cyanosis) to the skin, lips, and nail beds.. Cyanotic heart defects include:. ...
DefinitionCyanotic heart disease refers to a group of many different heart defects that are present at birth (congenital). They result in a low blood oxygen level.
Congenital heart defects (CHDs) are the most commonly reported major birth defect. Severe CHDs, the forms requiring early treatment at a cardiac center, have an incidence of approximately 3 per 1000 live births; the majority of these are cyanotic lesions. Although the overall incidence has climbed over the years, perhaps because of improved diagnostic methods such as echocardiography, the incidence of the major cyanotic types has remained fairly stable. ...

Right atrial appendages were obtained from: 1) 19 patients (9 male and 10 female; age range 3 months to 21 years) with acyanotic congenital heart disease who underwent open-heart surgery because of a ventricular septal defect (n = 8) or atrial septal defect (n = 11). Their parents had given informed, written consent. The study was approved by the local Ethics Committee. None of the children or young adults had acute heart failure or had been treated with sympathomimetic or sympatholytic agents for at least three weeks before the operation. Anesthesiologic premedication and surgery were carried out exactly as recently described (14,15). Right atrial appendages were removed immediately after installation of the cardiopulmonary bypass. 2) Twenty-three adult patients with coronary artery disease (18 male and 5 female; age range 45 to 76 years) undergoing coronary artery bypass graft surgery without apparent heart failure (New York Heart Association [NYHA] functional class 0/I: n = 5; class II: n = ...
The bidirectional Glenn procedure is an integral step in the optimal palliation for single ventricular physiology in many forms of complex congenital heart disease. An increasing number of women who have undergone this connection in childhood are now reaching childbearing years. Low pulmonary blood flow and volume over load on the single ventricle pose several problems during pregnancy. We are reporting a 33-year-old lady with congenital tricuspid atresia and mild pulmonary stenosis who had late Bidirectional Glenn procedure with pulmonary forward flow and later underwent six successful pregnancies, with delivery of six low birth weight babies with no reported complications.
Cyanosis is the bluish or purplish discolouration of the skin or mucous membranes due to the tissues near the skin surface having low oxygen saturation. Based on Lundsgaard and Van Slykes work,[1] it is classically described as occurring if 5.0 g/dL of deoxyhemoglobin or greater is present.[2] This was based on an estimate of capillary saturation based on a mean of arterial versus peripheral venous blood gas measurements.[3] Since estimation of hypoxia is usually now based either on arterial blood gas measurement or pulse oximetry, this is probably an overestimate, with evidence that levels of 2.0 g/dL of deoxyhemoglobin may reliably produce cyanosis.[4] Since, however, the presence of cyanosis is dependent upon there being an absolute quantity of deoxyhemoglobin, the bluish color is more readily apparent in those with high hemoglobin counts than it is with those with anemia. Also, the bluer the color, the more difficult it is to detect on deeply pigmented skin. When signs of cyanosis first ...
Cyanosis is a physical sign causing bluish discoloration of the skin and mucous membranes. It is caused by a lack of oxygen in the blood, and is associated with cold temperatures, heart failure, lung diseases, and smothering. Cyanosis is seen in infants at birth as a result of heart defects, respiratory distress syndrome, or lung and breathing problems.. Blood contains a red pigment (hemoglobin) in its red blood cells. Hemoglobinpicks up oxygen from the lungs, then circulates it through arteries and releases it to cells through tiny capillaries. After giving up its oxygen, blood circulates back to the lungs through capillaries and veins. Hemoglobin, as well as blood, is bright red when it contains oxygen, but appears dark or bluish after it gives up oxygen.. The blue discoloration of cyanosis is seen most readily in the beds of the fingernails and toenails, and on the lips and tongue. It often appears transiently as a result of slowed blood flow through the skin due to the cold. As such, it is ...
Do symptoms like cyanosis go away quickly - Do symptoms like cyanosis go away quickly? Depends. Cyanosis is only relieved with oxygen. Total body cyanosis, like from COPD or pneumonia may need supplemental oxygen. If local to a finger like in reynauds, then will improve when vascular spasm ends and oxygenated blood flow resumes.

Acrocyanosis is a painless disorder that affects the arteries supplying blood to the skin of the hands and feet. These small arteries carry oxygen and nutrients through the blood to the skin of the extremities. Spasms in the arteries block blood flow in people with this condition. Without adequate blood supply, the skin lacks oxygen, which changes the skin color to a dark blue to purple color. This characteristic color is called cyanosis ...

Venous blood lactic acid and pyruvic acid concentrations and lactate-pyruvate ratio were studied in 42 normal adults, 16 normal children and 18 children with congenital heart disease. There was elevation of resting values in children as compared with adults, but no significant change of values of resting children with congenital heart disease as compared with normal children. Following a standard exercise test, children with patent ductus arteriosus showed a time curve comparable to normal children, but children with cyanotic heart disease showed a persisting elevation of all values. The lactate-pyruvate ratio varied inversely with calculated mean capillary blood pO2.. ...
INTRODUCTION. According to the Baltimore-Washington Infant Study, tetralogy of Fallot (TOF) is the most common form of cyanotic congenital heart disease and accounts for 6.7% of all live babies born with congenital heart disease.1 Tetralogy of Fallot comprises four heart defects: a large ventricular septal defect (VSD), overriding aorta, right ventricular (RV) hypertrophy, and RV outflow tract obstruction (RVOTO). This latter abnormality determines the clinical course of the patient; for example, patients with minimal obstruction will have physiological signs, such as a VSD with a net left-to-right shunt and mild to no cyanosis (referred to as a pink tet), whereas those with severe obstruction will be severely cyanotic and require early intervention. Approximately 80% of patients with TOF will have degrees of pulmonary stenosis, and 20% will have pulmonary atresia.1. Patients with TOF typically undergo VSD closure and relief of the RVOTO within the first 6 months of life. The type of surgery ...
Red blood cells provide oxygen to body tissues. Most of the time, nearly all red blood cells in the arteries carry a full supply of oxygen. These blood cells are bright red and the skin is pinkish or red.. Blood that has lost its oxygen is dark bluish-red. People whose blood is low in oxygen tend to have a bluish color to their skin. This condition is called cyanosis.. Depending on the cause, cyanosis may develop suddenly, along with shortness of breath and other symptoms.. Cyanosis that is caused by long-term heart or lung problems may develop slowly. Symptoms may be present, but are often not severe.. When the oxygen level has dropped only a small amount, cyanosis may be hard to detect.. In dark-skinned people, cyanosis may be easier to see in the mucous membranes (lips, gums, around the eyes) and nails.. People with cyanosis do not normally have anemia (low blood count). Anemia is a condition in which the body does not have enough healthy red blood cells ...

An 18 year-old man presented with gradually progressive dyspnea. Examination revealed grade 3 clubbing and cyanosis of all extremities except the right upper limb (A). Left parasternal heave and palpable second heart sound, but no murmur, were observed. Electrocardiogram showed right ventricular (RV) hypertrophy (B). Chest radiograph showed dilated pulmonary artery and decreased lung vascularity (C). Contrast echocardiography (D and E) (Online Videos 1, 2, and 3) and computed tomography imaging (F and G) revealed large (18 mm) type B patent ductus arteriosus (PDA) with pulmonary-to-systemic shunting. The RV and pulmonary arteries were dilated with severe pulmonary hypertension (Online Figs. 1, 2, and 3). The patient was managed medically.. Differential cyanosis and clubbing is typical of PDA with Eisenmengers syndrome. Shunt reversal causes deoxygenated blood from the RV to be shunted to the aorta (Ao) distal to left subclavian artery (LSCA). This leads to selective affection of lower ...

N2 - Tetralogy of Fallot (ToF) is the most common cyanotic congenital heart disease, for which patients require surgical intervention at a very young age. Although these patients have long survival rates, they are at risk of chronic complications and frequently require re-operations with the most common being pulmonary valve replacement (PVR). However, the decision for surgical intervention is currently based on clinical indications and the right timing for PVR remains ambiguous [1,2]. The overall objective of this work is to identify a computational metric that will help assess the right timing for surgical intervention in adults with repaired tetralogy of Fallot. This current study concerns a preliminary computational analysis of blood flow in ...

Cyanotic congenital heart disease comprises a diverse spectrum of anatomical pathologies. Common to all, however, is chronic hypoxia before these lesions are operated upon when cardiopulmonary bypass is initiated. A range of functional and structural adaptations take place in the chronically hypoxic heart, which, whilst protective in the hypoxic state, are deleterious when the availability of oxygen to the myocardium is suddenly improved. Conventional cardiopulmonary bypass delivers hyperoxic perfusion to the myocardium and is associated with cardiac injury and systemic stress, whilst a normoxic perfusate protects against these insults.

Cardiovascular disease is a leading cause of mortality in all ages worldwide. Tetralogy of Fallot (TOF) is the most common cyanotic congenital heart disease (CHD) accounting for 10%. There have been several reports of neurological complications associated with TOF. Although it is known, brain abscess (BA) is a serious complication in patients with uncorrected CHD mostly in the age of 4-7 years-old. We report a case of a 7 year old male who presented with a 3 month history of left sided body weakness and a 3 week history of a headache and fever. Patient was chronically unwell since birth where he would experience occasional episodes of exertional dyspnoea which was never investigated. Chest xray showed a globular-shaped heart. CT scan brain showed a 1,8 x 1,3 x 1,5 cm ring-enhancing lesion in the right parietal region with minimal perilesional vasogenic edema communicating with the body of the lateral ventricle, with enhancement of the ependymal lining of the ventricle; echocardiography revealed

The bluish coloration of skin and mucous membranes, called as cyanosis, could be explained by high reduced hemoglobin in the capillaries, or the presence of elevated methemoglobin concentration. It is important to think of methemoglobinemia as a differential diagnosis in a cyanotic patient who does not respond to oxygen administration once cardiorespiratory causes are discarded; since it requires other diagnostic methods and specific treatment.

Tetralogy of Fallot (ToF) is the most common cyanotic congenital heart disease and the population of ToF repair survivors is growing rapidly. Adults with repaired ToF develop late complications. The aim of this study was to describe and analyze long-term follow-up of patients with repaired ToF. This is a retrospective cohort study. Consecutive 83 patients with repaired ToF who did not undergo pulmonary valve replacement were included. Mean age of all patients was 30.5 ± 10.7. There were 49 (59%) male. Patients were divided into two groups according to the time since the repair (| 25 years and ≥ 25 years). The electrocardiographic (ECG), cardiopulmonary exercise testing (CPET), echocardiographic and cardiac magnetic resonance (CMR) data were reviewed retrospectively. In CPET values were not significantly different in the two groups. In CMR volumes of left and right ventricles were not significantly different in the two groups. There were no differences between the groups in ventricular ejection

dextro-Transposition of the great arteries (d-Transposition of the great arteries, dextro-TGA, or d-TGA), sometimes also referred to as complete transposition of the great arteries, is a birth defect in the large arteries of the heart. The primary arteries (the aorta and the pulmonary artery) are transposed. It is called a cyanotic congenital heart defect (CHD) because the newborn infant turns blue from lack of oxygen. In segmental analysis, this condition is described as ventriculoarterial discordance with atrioventricular concordance, or just ventriculoarterial discordance. d-TGA is often referred to simply as transposition of the great arteries (TGA); however, TGA is a more general term which may also refer to levo-transposition of the great arteries (l-TGA). Another term commonly used to refer to both d-TGA and l-TGA is transposition of the great vessels (TGV), although this term might have an even broader meaning than TGA. In a normal heart, oxygen-depleted (blue) blood is pumped from the ...

Click picture to show/hide bloodflows). Pathophysiology. Tricuspid insufficiency or stenosis and right ventricular impairment limit blood flow through the right heart and into the pulmonary artery. Increased right atrial pressure due to limited outflow leads to right-to-left shunting through the patent foramen ovale. This shunting causes a variable degree of cyanosis and cardiomegaly which is present at birth and is sometimes accompanied by tachypnea. Both pulmonary arterial resistance and right-to-left shunting decrease in the days and weeks after birth which may lessen the cyanosis initially present in infancy. With severe insufficiency of the tricuspid valve, the right ventricle might not generate pressures high enough to open the pulmonary valve, thus causing functional atresia and ductal dependency.. Therapy. During infancy, Ebstein's anomaly is typically managed by administering prostaglandins and/or nitrous oxide to increase pulmonary blood flow and control cyanosis. Complex surgical ...
During a breath-holding spell, your child holds his or her breath for a while before briefly losing consciousness. Breath-holding spells often happen after a trauma or an emotional upset. They occur most often in children under age 3. Breath-holding spells can be scary for both parents and children. But they are not usually a serious problem. And they often stop by the time your child is 5 or 6 years old.
The shape of your foot molds the cast. It lets your ulcer heal by distributing weight and relieving pressure. If you have Charcot foot, the cast controls your foots movement and supports its contours if you dont put any weight on it. To use a total contact cast, you need good blood flow in your foot. The cast is changed every week or two until your foot heals. A custom-walking boot is another way to treat your Charcot foot.

Tetralogy of Fallot (TOF) is one of the most common congenital heart disorders (CHDs). This condition is classified as a cyanotic heart disorder, because tetralogy of Fallot results in an inadequate flow of blood to the lungs for oxygenation (right-to-left shunt) (see the following image).

In the past, children with right-to-left shunt lesions such as Tetralogy of Fallot defects were palliated with a systemic to pulmonary artery shunt. This prevented cyanosis while the child grew to a size where complete repair could be undertaken. With the improvements in surgical technique and critical care, there is a push to do a primary complete repair for these defects at younger and younger ages. These operations should be delayed as long as possible to allow for growth but not so long that there is unnecessary cyanosis and hypoxemia.. Study Design and Methodology:.

mutations 5,6,7,8 . Most patients are asymptomatic and account for 13% to 55% of patients in different series 4,5,6,7,8,9,10,11 .The classic triad of dyspnea, cyanosis, and clubbing is present in only 10% of patients with PAVMs 4 . The direct communication between the pulmonary and systemic circulation bypasses the capillary bed and this right-to-left-shunt causes hypoxemia and the absence of a filtering capillary bed allows embolism that can reach the systemic arteries inducing clinical sequelae, especially in the cerebral circulation with brain abscesses and stroke. These processes account for clinical features such as dyspnea, fatigue, hemoptysis, cyanosis and polycythemia 12 . The most common presenting symptom is dyspnea on exertion (31% to 67% of patients), and severity of dyspnea is related to the degree of hypoxemia and magnitude of the right-to-left shunt. Majority of the patients with PAVMs tolerate hypoxemia well and are relatively asymptomatic unless the arterial oxygen pressure is ...
