We have shown that late clinical arrhythmia in patients with the Mustard procedure for transposition of great arteries relates to impaired systemic right ventricular function.. Our radionuclide angiographic data reinforce previous studies showing systemic right ventricular dysfunction in patients undergoing the Mustard procedure for transposition of great arteries.4 5 18 Many of our adult patients were asymptomatic at follow up. However, during exercise stress, their cardiac limitations became apparent, as manifested by their decreased maximum workload, diminished anaerobic threshold andV˙o 2max, and lower systemic ventricular ejection fraction.19-21 Maximum oxygen uptake of 17.5 ml/kg/min at a mean of 23.4 years after the Mustard procedure in our adult cohort was significantly lower than the mean of 27 ml/kg/min at 10.3 years after Mustard operation in a report on young adolescents.22 Right ventricular ejection fraction from the present series, both at rest (44.5%) and during exercise (49.3%), ...
D-TGA is one of the most common forms of congenital heart disease, constituting 5% to 7% of cardiac malformations. Since the original description of the arterial switch operation in 1975 by Jatene et al,9 the arterial switch operation has become the procedure of choice for repair of D-TGA with intact ventricular septum or ventricular septal defect. Because of the rapid decline in the work capacity of the left ventricle after birth in children with D-TGA with an intact ventricular septum or a small ventricular septal defect, anatomic correction with the arterial switch operation must be performed during the first weeks of life.10 This practice provides a uniformity of age at repair that is rare among congenital heart defects. Furthermore, the arterial switch operation is performed with extremely low early mortality rates, negligible late mortality rates, and infrequent need for reoperation.1,11 We previously reported that neurocognitive performance in children with D-TGA has been below expected ...
TY - JOUR. T1 - Pregnancy Outcomes After Atrial Repair for Transposition of the Great Arteries. AU - Canobbio, Mary M.. AU - Morris, Cynthia D.. AU - Graham, Thomas P.. AU - Landzberg, Michael J.. PY - 2006/9/1. Y1 - 2006/9/1. N2 - Increasingly, women born with complete transposition of the great arteries who have undergone atrial repair by either the Senning or the Mustard procedure are reaching childbearing age. This study reports on pregnancy outcomes after the atrial repair of transposition of the great arteries. Record review and standardized questionnaires were used to ascertain the outcomes of 70 pregnancies reported in 40 women (36 Mustard procedures, 4 Senning procedures). Of the 70 pregnancies, 54 resulted in 56 live births, 10 in miscarriages, and 6 in therapeutic abortions. At pregnancy, 31 women were in New York Heart Association class I, 8 were in class II, and 1 was in class III. Thirty-nine percent of the infants were delivered prematurely and weighed 2,714 ± 709 g; 28% were ...

N2 - Mitral valve anomalies can occur with S,D,D-transposition of the great arteries (d-TGA). Their influence on surgical technique and outcome after an arterial switch operation (ASO) has not been well described. Patients with d-TGA who underwent ASO from February 1990 to January 2011 were identified. Echocardiograms, operative reports, hospital course, and latest follow-up evaluation were reviewed. A total of 218 infants underwent ASO at a median age of 15.8 days. Survival was 95 % during a mean follow-up period of 60 months. Nine patients (4 %) were found to have similar mitral valve anomalies including anterior malalignment conoventricular septal defect, anterior displacement of ...
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 ...
Retraining the morphological left ventricle in transposition of the great arteries has been successfully reported in infancy, while older age seems to be a contraindication. A 23-year-old woman with ¿S,D,D¿ transposition of the great arteries and ventricular septal defect developed severe right systemic ventricular dysfunction 22 years after Mustard procedure and ventricular septal defect closure. Hemodynamic investigation revealed moderate pulmonary hypertension and preserved left ventricular function. A pulmonary artery band was applied to obtain a left-right ventricular pressure ratio of 0.91. Her postoperative course was characterized by biventricular failure, treated effectively with inotropic support. Six months later, she underwent a Mustard baffle takedown and arterial switch procedure. Her postoperative course was uneventful. She was discharged home on postoperative day 15. At 24-months follow-up, she is in excellent clinical condition; echocardiographic evaluation shows good left ventricular
BACKGROUND: There is no clinical evidence supporting medical treatment for the failing systemic right ventricle in patients with transposition of the great vessels with atrial switch. Cardiac magnetic resonance studies have shown a significant degree of myocardial fibrosis in right ventricles in the systemic position, which predisposes to systolic and diastolic dysfunction. Aldosterone is a widely recognized neurohormonal marker involved in the formation of myocardial fibrosis and the treatment with aldosterone antagonists has shown a decrease in ventricular mass in hypertensive patients, presumably related to reduction of myocardial fibrosis.. HYPOTHESIS: Low dose of eplerenone, a selective mineralocorticoid receptor blocker, in patients with systemic right ventricle can reduce the ventricular mass by means of a reduction in myocardial fibrosis, resulting in improved systolic function.. PATIENTS AND METHODS: Randomized, double blind, parallel clinical trial comparing eplerenone (50mg daily) ...
The Mustard procedure was largely replaced in the late 1980s by the Jatene procedure (arterial switch), in which the native arteries were switched back to normal flow, so that the RV (right ventricle) would be connected to the pulmonary artery and the LV (left ventricle) would be connected to the aorta. This surgery had not been possible prior to 1975 because of difficulty with re-implanting coronary arteries which perfuse the actual heart muscle itself (myocardium), and even after it was first performed the excellent results from the Mustard operation meant that it was a long time before the Jatene procedure took over. ...
Perspective: Systemic right ventricles are at high risk of contractile dysfunction, the cause of which is still unclear. The chronic exposure of the morphological right ventricle to systemic pressure leads to significant hypertrophy. Ischaemia has been postulated to contribute to the right ventricular systolic dysfunction by a number of mechanisms. Supply demand mismatch from an inadequate coronary circulation to support the hypertrophied right ventricle may contribute. In addition, systemic arterial hypoxaemia in the preoperative period and the cardiopulmonary bypass for correction may damage the RV myocardium1, 2, 3. Small numbers of paediatric and adult patients with systemic right ventricles have been studied using myocardial perfusion single photon emission tomography (SPECT) with Sestamibi. A variety of fixed and inducible perfusion defects have been described and believed to be associated with the degree of right ventricular dysfunction and the delay to corrective surgery 2, 3. Myocardial ...
The coronary arteries are a major concern in anatomical correction of d-transposition of the great arteries. The necropsy study was undertaken to assess the feasibility of direct bilateral reimplantation as described by Fatene et al. This seemed possible in only 30 per cent of 100 cases, and furthermore was related to the type of coronary artery pattern. ...

This is a randomized, controlled, prospective trial on the safety of physical training in TGA patients after atrial switch operation.. In transposition patients after atrial switch operation, the morphological right ventricle serves as the systemic ventricle. These patients often develop signs of heart failure. It is not known, whether physical training can safely be recommended in these patients- like heart failure guidelines recommend training in patients with normal anatomy. Furthermore it is not known, whether these TGA-patients benefit from training with respect to cardiopulmonary exercise capacity.. Primary endpoints are Systemic Ventricle Ejection Fraction and Volumes, Exercise Capacity.. Secondary endpoints are Echo Diastolic Function, as well as laboratory markers of heart failure. ...
The hippocampus is vulnerable to perinatal hypoxic/ischaemic insults with potential memory impairment in later life. We measured memory and hippocampal integrity in survivors of the Arterial Switch Operation (ASO) for Transposition of Great Arteries (TGA).. Methods We recruited 35 neurodevelopmentally normal children [mean (SD) age 10.9 (0.4) years] who had ASO and 21 age-matched healthy controls [11.6 (0.3) years]. Preterms and those with genetic syndromes and additional heart abnormalities were excluded. Clinical and intra-operative variables were analysed. All had standardised tests of intelligence, general memory and learning, academic achievements, and a special test of episodic memory (Rivermead Behavioural Memory Test). Hippocampal volumes (mm3) were measured using MRI corrected for intracranial volume.. Results In the 35 studied, 2 groups were identified: 25 with intact ventricular septum (TGA-IVS) and 10 with ventricular septal defect (TGA-VSD); median (IQR) age at ASO was 13 (9.5, ...
In this study, we present the results of 40 consecutive patients who underwent Senning procedure between September 1983 - March 1992. Mean age at operation was 28 months (range 4 months to 9 years). Early postoperative mortality was 9.5% (2/21, 70% confidence limit; 3,1% - 21%) in the patients with simple TGA. Seven of 19 patients with complex TGA (TGA + VSD + PH/PS) died in the early postoperative period. Persistant pulmonary hypertention was the main reason for early deaths in the patients with TGA + VSD + PH (5/9,55%, 70% CI:38%-75%). In the group of TGA + VSD + PS, 2 patients were died (20%, 70% CI; 7%-40%). Mean follow up is 44 months (2 to 102 months). Only one late death was happened due to endocarditis. All surviving 30 patients are doing well. Their periodical examinations and Doppler echocardiographic controls showed neither systemic nor pulmonary venous obstruction. They are in NYHA functional class I or II. Because of the decreased early mortality rates and the satisfying medium / ...

Helpful, trusted answers from doctors: Dr. Batlivala on how long is the recovery for a baby with transposition of the great vessels: The most common type of transposition of the great vessels (also known as transposition of the great arteries) is d-transposition or d-tga. Infants with d-tga only are usually discharged from the hospital less than one week following surgery. The often require medication for a few weeks after surgery. The breast bone, which is divided to perform the surgery, fully heals in 6 weeks.
Cases of TGA can be more complicated than this description. In some cases the arterial switch operation cannot be performed, and other kinds of surgery can be offered (Rastelli, Senning, Fontan).. After surgery it is not uncommon for a baby to pick up an infection, such as a chest infection or infected wound, while undergoing treatment. Some children react badly to some kinds of medicines. The kind of surgery needed can sometimes cause a very fast pulse rate (called tachycardia), which may need medication to keep it stable. But most babies are completely well, pink, active, and gaining weight a few days after surgery. He or she will have a scar down the middle of the chest, and there may be small scars where drain tubes were used. These fade very rapidly, but they will not go altogether. Smaller scars on the hands and neck usually fade away to nothing. A child who has had an arterial switch operation will be monitored as there can be problems in the development of the arteries to the lungs ...
We performed the Senning operation and pulmonary valvotomy in an 11-month-old baby with transposition of the great arteries (TGA) with an intact ventricular septum (IVS), and bicuspid pulmonary valvular stenosis associated with pulmonary hypertension (PH). Preoperative catheterization showed a pressure gradient (PG) between the left ventricle (LV) and main pulmonary artery (MPA) of 35mmHg, mean pulmonary artery pressure (MPAP) of 56mmHg, and pulmonary vascular resistance (PVR) of 11.2 unit m2. The pure oxygen inhalation test showed a decrease in MPAP from 56 to 38mmHg, and a decrease in PVR from 11.2 to 5.5 unit m2. We could not perform lung biopsy to determine the surgical indications in terms of PH due to preoperative progressive congestive heart failure in this patient. Postoperative catheterization (28 days after the Senning operation) showed a decrease in PG between the LV and MPA to 8 mmHg, and MPAP also decreased to 17 mmHg. Two radical operations were possible in this patient. One was ...
A randomized controlled trial was performed at three centers. The patient population included adults with congenitally corrected as well as surgically palliated transposition of the great arteries (TGA). Patients with New York Heart Association (NYHA) functional class III or IV were excluded. The exercise protocol consisted of 32 minutes of step aerobics interval training three times per week for 10 consecutive weeks. Patients exercised to 90% of maximum heart rate based on prerandomization exercise testing. Perceived health status was measured with the short form-36 (SF-36) instrument, while quality of life was measured with the TAAQOL instrument, which was specifically designed to study quality of life in adults with congenital heart disease. Patients underwent exercise testing, measurement of NT-proBNP, and assessment of quality of life at enrollment and after the study period.. ...

Dr. Matos-Cruz responded: Depends on anatomy. Goal if possible is to achieve, atrioventricular and ventriculoarterial concordance as best possible. Some transpositions of the great arteries are congenitally corrected if baby born with atrioventricular and ventriculoarterial discordance. Is it d or l tga, how many concomitant anomalies are present. If d-tga, no vsd, good valves, no coronary anomalies, good lv and rv, ASD closure and jatene best.
Transposition of the Great Arteries (TGA) D-TGA is when aorta arises from RV And PA arises from LV. Most common form of transposition. Important associated defects for surgical planning are malalignment septal defects. Anterior (rightward) defects are associated w/ varying degrees of overriding of pulmonary annulus onto RV. Posterior (leftward) malalignment defects are
Prepare a smoker to run at 225 degrees with around 4 chunks of apple wood and 4 chunks of cherry wood so that the wood will smolder throughout the cooking. Remove the ribs from the refrigerator, unwrap, and repeat the rub and mustard procedure, massaging them in. Dont get it too thick or paste-like, as this will give you a dark appearance when cooked. Place the ribs in the smoker meat side up and cook for 2 hours. Remove the ribs from the smoker and increase the temperature to 250 degrees. Apply rub and mustard to both sides of the ribs as before. On the top sides, slather approximately 1 tablespoon of honey over the surface, then sprinkle heavily with Turbinado sugar. Lay the ribs meat side up on a piece of heavy-duty aluminum foil and fold up the edges. Pour approximately 1 to 2 ounces of purple grape juice into the bottom of the foil, then finish wrapping the ribs but dont crimp the edges-you want steam to be able to escape. ...

The most common hemodynamic problem encountered in this cohort was SAVV regurgitation in the setting of impaired SV function. Of the 68% of patients who required surgical intervention, all needed SAVV replacement as part of the surgical repair. The relation between SAVV regurgitation and SV dysfunction in CTGA is complex and is not completely understood (9,10,13-15). In the majority of patients with CTGA, the SAVV is morphologically abnormal (16). With time, the valve deteriorates, and there is increasing regurgitation (11). This chronic volume load on the SV, in turn, leads to annular and ventricular dilation, resulting in malcoaptation and worsening regurgitation (17). In a study with a mean follow-up of 20 years (13), the presence of a morphologically abnormal SAVV was the only predictor of severe SAVV regurgitation, and severe SAVV regurgitation was the only independent predictor of long-term survival in both operated and unoperated patients with CTGA..

In transposition of the great vessels, the major blood vessels attached to the heart-the aorta and the pulmonary artery-are reversed. This reversal results in the blood going to the wrong places. This leads to low oxygen levels in the body. The aorta, which normally carries oxygen-rich blood from the left side of the...
A normal heart is divided into two sides. The right side pumps blood from the body into the lungs. The left side pumps the blood from the lungs out to the body. Each side has an atrium and a ventricle. The atrium acts like a "waiting room" for the blood. The ventricle does the hard work of pushing the blood out to the lungs or body. At the entrance and exit from each ventricle is a valve, which acts like a door. These valves allow the ventricle to fill with blood from one side, and then push it out the other.. Each ventricle and valve is designed to do its specific job. The right ventricle is designed to give the blood a gentle push to send it to the lungs. It is bigger than the left ventricle and does not have as much muscle. The left ventricle is designed to give the blood a strong push out to the body. It has less space inside because its thick walls take up more space. The valve between the left atrium and ventricle, the mitral valve, is the bodys strongest valve. It is designed to stay ...

The duodenal switch procedure is a relatively new type of bariatric surgery that many people are using to great benefit. Sometimes abbreviated BPD/DS, duodenal switch surgery is so named because it has two major components to the procedure. What Exactly is a Duodenal Switch Procedure? The first portion of the small intestine is known as the duodenum. This part of the body is located just outside the stomach outlet. In a duodenal switch procedure, the duodenum is divided into two pieces where the small intestine meets the stomach. A small portion of the small intestine is connected to the stomach that is just been created. This redirects food through the artificially created stomach pouch, emptying the stomach directly into the last part of the small intestine. The purpose of the surgery is to bypass as much of the small intestine as possible, and in a successful surgery, up to three-forths of the small intestine will be bypassed. What Does Duodenal Switch Surgery Do? The duodenal switch procedure is
Bulboventricular foramen obstruction nay complicate the management of patients with single left ventricle. Bulboventricular foramen size was measured in 28 neonates and infants ,5 months old and followed up for 2 to 5 years in those patients whose only sytemic outflow was through the foramen. The bulboventricular foramen was measured in two planes by two-dimensional echocardiography, its area calculated and indexed to body surface area. One patient died before surgical treatment. The mean initial bulboventricular foramen area index was 0.94 cm2/m2in 12 patients (Group A) in whom the foramen was bypassed as the first procedure in early infancy. The remaining 15 patients underwent other palliative operations but the bulboventricular foramen continued to serve as the systemic outflow tract. There was one surgical death. Six (Group B) of the 14 survivors developed bulboventricular foramen obstruction during follow-up (mean initial bulboventricular foramen area index 1.75 cm2/m2). The remaining eight ...

In some congenital heart defects (CHDs), the sinus node is missing or does not work properly. It can also be damaged during heart surgery. This is especially common in operations that place sutures or patches in the sinus node area. These include the Fontan, Senning, or Mustard procedures. Sometimes tubing for the bypass machine can damage the sinus node or its blood supply. If this happens, your heart may beat slower (bradycardia). Regardless of the reason, if your sinus node is not working well for any reason, your adult congenital heart disease (ACHD) cardiologist may prescribe medications or recommend a pacemaker to help increase your heart rate.. The second major part of the electrical system in the heart is the AV node. The AV node is located in the middle of the heart between the upper and lower chambers. Its main job is to help manage the electrical activity as it travels from the atrium to the ventricles. The AV node slows down the electrical message slightly. This delay allows time for ...
... : Transposition of great arteries is a birth defect of the heart in which aorta originates from the right ventricle (instead of the normal left ventricle) and pulmonary artery arises from the left ventricle (instead of the normal right ventricle). This results in deoxygenated blood from the right ventricle reaching the body instead of the lungs. Hence these babies are blue at birth (cyanotic congenital heart disease).. ...
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, ...

The increasing survival to adulthood of patients with congenital heart disease (CHD) has changed the epidemiology of adult CHD (ACHD) patients and has led to an increment in hospitalization rates due to heart failure (HF). ACHD patients hospitalized for HF have a five-fold higher risk of death than those compensated. HF occurs predominantly in patients with tetralogy of Fallot, single ventricles, and after the Mustard operation for transposition of the great arteries. Diagnostic strategies applied in acquired HF patients are usually used to evaluate ACHD patients, but sometimes this can postpone the identification of HF that can become manifest with unusual and peculiar signs or symptoms. In the same way, therapeutic management resembles the acquired HF one, even if no large randomized clinical trials have been conducted in ACHD patients. Therefore, a close monitoring in dedicated units is mandatory in order to identify in time HF manifestations and manage them adequately.. ...
The first clue came with a murmur.. At a mere week old, Joe LaRocca was diagnosed with an extraordinarily rare heart defect. Both ventricles were reversed.. Fortunately, with this particular defect, the arteries are reversed too, essentially "correcting" the abnormality. Thats where it gets its name - congenitally corrected transposition of the great arteries (CCTGA).. In a normal heart, the demanding duty of pumping oxygenated blood into the body is handled by the left ventricle, and the right ventricle pumps blood a short distance into the lungs. But Joes heart was far from normal.. "The right ventricle is not meant to do the harder work," says Dr. Elizabeth Blume, Heart Failure and Heart Transplant Program medical director at Boston Childrens Hospital. "Since the ventricles are reversed in patients with CCTGA, over time, this muscle tires out.". For the past three decades, the team at Boston Childrens Heart Center has medically and surgically managed Joes condition. And at 33, his heart ...

One of the most important things I have learned on rotations is to look at patients as a whole and individualize their treatment. This concept is even more critical in pediatrics. In adults, slightly overestimating a dose, in most cases, will not have fatal consequences. In children, it very well can. Children cannot be treated as miniature adults. When I was working up patients on the PSICU, there were many things that I had to take into account in addition to the normal parameters, lab values, etc in an adult workup. The most basic was the patients size ie weight, height, and head circumference and the percentiles they fit into compared with others of their age. Secondly, it was important to collect an extensive maternal history, given that the patient him/herself does not a considerable past medical history. Thirdly, the normal ranges for many lab values (ie potassium, T. bili, albumin, serum creatinine) and vital signs (ie blood pressure, heart rate) changes with age. Lastly, there was a ...
The great vessels of the heart are a collection of arteries and veins which drain blood into the atria, and take blood away from the ventricles. These are different from the coronary vessels of the heart - which vascularise the heart muscle itself.

A 15-year-old girl with D-transposition of the great arteries presented with combined neo-pulmonary stenosis and regurgitation following arterial switch operation as a neonate and neo-pulmonary valvectomy at 6 years of age. Echocardiography revealed right ventricular enlargement and severe neo-pulmonary regurgitation and stenosis with a mean Doppler gradient of 47 mm Hg. Right ventricular end-diastolic volume by cardiac magnetic resonance was 201 ml/m2. She underwent cardiac catheterization with 3-dimensional (3D) DynaCT rotational angiography and 3D reconstruction (Siemens, Munich, Germany) (Figure 1A, Online Videos 1 and 2). Catheterization demonstrated a peak-to-peak pulmonary gradient of 38 mm Hg. The right ventricular outflow tract (RVOT) measured 16 mm angiographically. Sequential placement of a 26-mm ev3 IntraStent LD Max (ev3-Endovascular, Plymouth, Minnesota) and a Palmaz-XL-3110 stent (Cordis, Johnson & Johnson, Bridgewater Township, New Jersey), both delivered over a 22-mm × 4-cm ...

La transposición de las grandes arterias (D-TGA) es una de las cardiopatías congénitas más comunes que requieren una intervención quirúrgica en la etapa neonatal. En neonatos muy afectados por una D-TGA, la hipoxemia, la acidemia y la insuficiencia cardiaca congestiva secundaria se mejora a menudo con una atrioseptostomía con balón (ASB). Los métodos actuales empleados para evaluar el aporte y el consumo de oxígeno tisular, con frecuencia no son específicos. La espectroscopia cercana al infrarrojo o near infrared spectroscopy (NIRS) permite una medición continua no invasiva de la oxigenación tisular, reflejando el estado de la perfusión tisular en tiempo real. Debido a que se sabe poco sobre el efecto directo de la ASB en el cerebro neonatal y en la oxigenación cerebral de los mismos, nosotros medimos la eficacia de la ASB en 2 pacientes con D-TGA utilizando el NIRS antes y después de la ASB. Concluimos que la ASB mejora la saturación cerebral de oxígeno en neonatos con ...

N2 - Background: Due to increasing success with repair or palliation in childhood, there is a rapidly growing population of adult patients with complex congenital heart disease who may require transplantation. There remains little data on outcomes of cardiac transplantation in this group. Methods: 38 orthotopic cardiac transplants were performed in 37 patients (18 men) ≥18 years of age with congenital heart disease (CHD) from 1988 to 2009 in our institution. Outcomes were reviewed using medical records and transplant databases. Results: 15 patients (41%) had univentricular and 22 (59%) biventricular physiology. The biggest group was transposition of the great arteries following atrial switch in ...
We present data on the relationship between the rate of transposition and copy number in the genome for the copia and Doc retrotransposons of Drosophila melanogaster. copia and Doc transposition rates were directly measured in sublines of the isogenic 2b line using individual males or females, respectively, with a range of copia copy numbers from 49 to 103 and Doc copy numbers from 112 to 235 per genome. Transposition rates varied from 3 x 10(-4) to 2 x 10(-2) for copia and from 2 x 10(-4) to 2 x 10(-3) for Doc. A positive relationship between transposition rate and copy number was found both for copia and for Doc when the data were analysed across all the 2b individuals; no significant correlation was found when the data were analysed across the subline means for both retrotransposons tested. Overall, correlation between copia and Doc transposition rate and their copy number in the genome, if any, was not negative, which would be expected if transposable elements (TEs) self-regulate their copy number.

Transposition of the great arteries or TGA is a potentially fatal congenital heart malformation where the pulmonary artery and the aorta are switched. The switch means that the aorta, which normally carries oxygenated blood, carries deoxygenated blood. There are two types of the malformation, d-TGA where no oxygen reaches the body and l-TGA where some oxygenated blood circulates. In the US, the Centers for Disease Control estimate that about 1,901 infants are born each year with TGA, or about one for every 2,000 births.. Format: Articles Subject: Disorders ...

In September 2012, 24-year-old Brooke Stone had her second lifesaving heart surgery, this time at Lucile Packard Childrens Hospital. When people ask about her chest scar, she gives them the simplest answer she can: I tell them I was born with my heart attached backwards.. As a newborn in 1988, Stone was diagnosed with a condition known as transposition of the great arteries, and underwent a complex surgery at UCSF to correct her blood flow. In TGA, the two main arteries that come out of the heart - the pulmonary artery and aorta - are connected to the wrong chambers of the heart. As a result, blood from the lungs flows back to the lungs and blood from the body flows back to the body without ever getting the oxygen it needs.. Transposition of the great arteries was almost 100 percent fatal before the late 1950s, said Frank Hanley, MD, director of the Childrens Heart Center at Packard Childrens and a professor of cardiothoracic surgery at the School of Medicine.. Stones first surgery - a ...

We found out Nate has a Ventricular Septum Defect (VSD) or hole in his heart where the left and right ventricles meet. That in itself could devastate a parent. However, the doctor said that wasnt all they found. Thats when our hearts dropped. She went on to explain Nates situation. He has Corrected Transposition of the Great Arteries. It is a congenital heart defect that would have happened at about 5 weeks gestation. You can google it to find out more about it, but basically the pulmonary artery and the aorta are around the wrong way, but it has been corrected by the fact that the ventricles are also around the wrong way. It would appear that the blood is going to the right places, but there are many other complications that arise from the weaker ventricle doing the hard work and the stronger ventricle pumping blood at a higher pressure to the lungs. They include surgery to repair the VSD, surgery to correct the arteries and ventricles, inserting a pacemaker, etc. We got a crash course in ...
Transposition Buffer: Added 1.0165mg to each mL of NEB2 (MgCl2 tetrahydrate is 203.3g/mol and were attempting to copy a transposition buffer that contains 150mM of MgCl2). We added 36.6mg of MgCl2 to 32.4mL of water and 3.6mL of 10xNEB2 to make 150mM MgCl2 NEB2. We also added 5 drops of diluted HCl (tube labeled diluted HCl... we made it my dipping a pasteur pipette in the 12M HCL and then in 50mL of mgH20) to bring the pH from 7.8 to 7.6 or so. Spun down all 5mLs of cells and 1uL of control cells (no ara). Resuspended in NEB2+MgCl2 buffer. Transferred control into a tube. Combined all 5mL resuspended cells into one tube, and then separated into 5 tubes. Added 1uL of atc and 10uL of arabinose to each mL of cells at 1:05pm. Put in 37deg shaker. Started adding DNA at 1:40pm. For DNA, we mixed two minipreps of 9145-1144. Well, we mixed them after adding DNA from one of the MPs to the 1uL tubes and the 13 .5uL tube (Whoops). Somehow, we ran out of MP, so were only adding up to 10uL of DNA. Time ...

The common heart diseases resulting in a brain abscess are associated with a right to left shunt and include tetralogy of Fallot and transposition of great vessels. Atrial septal defect (ASD) is almost always associated with the left to right shunt and therefore is not a commonly considered risk factor for brain abscess. We report the case of a 29-year-old male, with no symptoms of cardiac disease, who presented with the left posterior frontal pyogenic abscess which led to the detection of a silent ASD. Our case emphasizes the need for a careful evaluation of the source of infection in patients with a brain abscess ...
In normal hearts, blood that returns from the body goes through the right side of the heart and pulmonary artery to the lungs to get oxygen. The blood then comes back to the left side of the heart and travels out the aorta to the body.. In TGA, venous blood returns normally to the heart through the right atrium. But, instead of going to the lungs to absorb oxygen, this blood is pumped out through the aorta and back to the body. This blood has not been recharged with oxygen and leads to cyanosis.. Symptoms appear at birth or very soon afterward. How bad the symptoms are depends on the type and size of additional heart defects (such as atrial septal defect, ventricular septal defect, or patent ductus arteriosus) and how much the blood can mix between the two abnormal circulations. ...
