Atrial Switch
Atrial switch is a heart operation performed to treat dextro-Transposition of the great arteries. It involves the construction of an atrial baffle which redirects the blood coming into the atria to restore the connection between systemic and pulmonary circulation. Two variants of the atrial switch operation developed – the Senning procedure (1950s) which uses the patient's own tissue (pericardium) to construct the baffle, and the Mustard procedure (1960s), which uses a synthetic material. It has largely been replaced by the arterial switch operation Arterial switch operation (ASO) or arterial switch, is an open heart surgical procedure used to correct dextro-transposition of the great arteries (d-TGA). Its development was pioneered by Canadian cardiac surgeon William Mustard and it was na .... The operation is more commonly performed in developing countries, where the condition frequently presents late. References Cardiac surgery {{cardiology-stub ...

Cardiology
Cardiology () is a branch of medicine that deals with disorders of the heart and the cardiovascular system. The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology. Physicians who specialize in this field of medicine are called cardiologists, a specialty of internal medicine. Pediatric cardiologists are pediatricians who specialize in cardiology. Physicians who specialize in cardiac surgery are called cardiothoracic surgeons or cardiac surgeons, a specialty of general surgery. Specializations All cardiologists study the disorders of the heart, but the study of adult and child heart disorders each require different training pathways. Therefore, an adult cardiologist (often simply called "cardiologist") is inadequately trained to take care of children, and pediatric cardiologists are not trained to treat adult heart disease. Surgical aspects are not included in cardiology ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardiac Surgery
Cardiac surgery, or cardiovascular surgery, is surgery on the heart or great vessels performed by cardiac surgeons. It is often used to treat complications of ischemic heart disease (for example, with coronary artery bypass grafting); to correct congenital heart disease; or to treat valvular heart disease from various causes, including endocarditis, Rheumatic fever, rheumatic heart disease, and atherosclerosis. It also includes heart transplantation. History 19th century The earliest operations on the pericardium (the sac that surrounds the heart) took place in the 19th century and were performed by Francisco Romero (surgeon), Francisco Romero (1801) in the city of Almería (Spain), Dominique Jean Larrey (1810), Henry Dalton (1891), and Daniel Hale Williams (1893). The first surgery on the heart itself was performed by Axel Cappelen on 4 September 1895 at Rikshospitalet in Kristiania, now Oslo.

Dextro-Transposition Of The Great Arteries
dextro-Transposition of the great arteries (d-Transposition of the great arteries, dextro-TGA, or d-TGA) is a potentially life-threatening 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. Prenatally, a baby with d-TGA experiences no symptoms as the lungs will not be used until after ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Senning Procedure
The Senning procedure is an atrial switch heart operation performed to treat transposition of the great arteries. It is named after its inventor, the Swedish cardiac surgeon Åke Senning (1915–2000), also known for implanting the first permanent cardiac pacemaker in 1958. Brief History This procedure, a form of atrial switch, was developed and first performed by Senning in 1957 as a treatment for d-TGA (dextro-Transposition of the great arteries) before improvements in cardiopulmonary bypass made more curative surgical techniques feasible.Atrial Switch Operation: Past, Present, and Future. Konstantinov IE, Alexi-Meskishvili VV, Williams WG et al.Ann Thorac Surg 2004;77:2250 – 8 In this congenital heart defect, the venous circulation drains into the right ventricle but from this chamber, blood is directed towards the systemic circulation through the aorta. This is also expressed by the term ventriculoarterial discordance, that is the ventricles are connected to the wrong great ...

Pericardium
The pericardium, also called pericardial sac, is a double-walled sac containing the heart and the roots of the great vessels. It has two layers, an outer layer made of strong connective tissue (fibrous pericardium), and an inner layer made of serous membrane (serous pericardium). It encloses the pericardial cavity, which contains pericardial fluid, and defines the middle mediastinum. It separates the heart from interference of other structures, protects it against infection and blunt trauma, and lubricates the heart's movements. The English name originates from the Ancient Greek prefix "''peri-''" (περί; "around") and the suffix "''-cardion''" (κάρδιον; "heart"). Anatomy The pericardium is a tough fibroelastic sac which covers the heart from all sides except at the cardiac root (where the great vessels join the heart) and the bottom (where only the serous pericardium exists to cover the upper surface of the central tendon of diaphragm). The fibrous pericardiu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mustard Procedure
The Mustard procedure was developed in 1963 by Dr. William Mustard at the Hospital for Sick Children in Toronto, Ontario, Canada. Dr. Mustard, with support from the Heart and Stroke Foundation of Canada, developed an alternative and simplified technique to the Senning procedure which was used to correct a congenital heart defect that produced “ blue babies”. The technique was adopted by other surgeons and became the standard operation for d-TGA. In his autobiography, South African cardiac surgeon Christiaan Barnard claims to have been the first to perform the operation, with Mustard only following 'several years later'. Background The defect is called transposition of the great vessels, or transposition of the great arteries (TGV or TGA). Until the late 1950s, and Senning's operation, the condition was commonly fatal. The defect causes blood from the lungs to flow back to the lungs and blood from the body to flow back to the body. This occurs because the aorta and the pul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arterial Switch Operation
Arterial switch operation (ASO) or arterial switch, is an open heart surgical procedure used to correct dextro-transposition of the great arteries (d-TGA). Its development was pioneered by Canadian cardiac surgeon William Mustard and it was named for Brazilian cardiac surgeon Adib Jatene, who was the first to use it successfully. It was the first method of d-TGA repair to be attempted, but the last to be put into regular use because of technological limitations at the time of its conception. Use of the arterial switch is historically preceded by two atrial switch methods: the Senning and Mustard procedures. The atrial switch, which was an attempt to correct the physiology of transposition, had significant shortcomings. The arterial switch sought to address them. This has emerged as an anatomically as well as physiologically appropriate solution.Marathe SP, Talwar S. Surgery for transposition of great arteries: A historical perspective.
