Blalock–Thomas–Taussig Shunt
The Blalock–Thomas–Taussig shunt (BTT shunt), previously known as the Blalock–Taussig Shunt (BT shunt), is a surgical procedure used to increase blood flow to the lungs in some forms of congenital heart disease such as pulmonary atresia and tetralogy of Fallot, which are common causes of blue baby syndrome. The procedure involves connecting a branch of the subclavian artery or carotid artery to the pulmonary artery. In modern practice, this procedure is temporarily used to direct blood flow to the lungs and relieve cyanosis while the infant is waiting for corrective or definitive surgery when their heart is larger. The BTT shunt is used in the first step of the three-stage palliation (the Norwood procedure). __TOC__ Alternatives While the originally described Blalock–Thomas–Taussig shunt directly connected the subclavian and pulmonary arteries, in contemporary practice a modified version of the procedure, the mBTT shunt, is more commonly used. In the modified Blalock ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polytetrafluoroethylene
Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is chemically inert. The commonly known brand name of PTFE-based composition is Teflon by Chemours, a corporate spin-off, spin-off from DuPont (1802–2017), DuPont, which originally invented the compound in 1938. Polytetrafluoroethylene is a fluorocarbon solid, as it is a high-molecular-weight polymer consisting wholly of carbon and fluorine. PTFE is hydrophobic: neither water nor water-containing substances Wetting, wet PTFE, as fluorocarbons exhibit only small London dispersion forces due to the low polarizability, electric polarizability of fluorine. PTFE has one of the lowest Friction#Coefficient of friction, coefficients of friction of any solid. Polytetrafluoroethylene is used as a non-stick coating for Cookware and bakeware, pans and other Cookware and bakeware, cookware. It is Chemically inert, non-reactive, partly because of the strength of car ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Something The Lord Made
''Something the Lord Made'' is a 2004 American made-for-television biographical drama film about the black cardiac pioneer Vivien Thomas (1910–1985) and his complex and volatile partnership with white surgeon Alfred Blalock (1899–1964), the "Blue Baby doctor" who pioneered modern heart surgery. Based on the National Magazine Award-winning '' Washingtonian'' magazine article "Like Something the Lord Made" by Katie McCabe, the film was directed by Joseph Sargent and written by Peter Silverman and Robert Caswell. Plot ''Something the Lord Made'' tells the story of the 34-year partnership that begins in Depression Era Nashville in 1930 when Blalock (Alan Rickman) hires Thomas (Mos Def) as an assistant at his Vanderbilt University lab, expecting him to perform janitorial work. Thomas' remarkable manual dexterity and intellectual acumen confound Blalock's expectations, and Thomas rapidly becomes indispensable as a research partner to Blalock in his forays into heart surgery.

Denton Cooley
Denton Arthur Cooley (August 22, 1920 – November 18, 2016) was an American cardiothoracic surgeon famous for performing the first implantation of a total artificial heart.

Anastomosis
An anastomosis (, : anastomoses) is a connection or opening between two things (especially cavities or passages) that are normally diverging or branching, such as between blood vessels, leaf veins, or streams. Such a connection may be normal (such as the foramen ovale in a fetus' heart) or abnormal (such as the patent foramen ovale in an adult's heart); it may be acquired (such as an arteriovenous fistula) or innate (such as the arteriovenous shunt of a metarteriole); and it may be natural (such as the aforementioned examples) or artificial (such as a surgical anastomosis). The reestablishment of an anastomosis that had become blocked is called a reanastomosis. Anastomoses that are abnormal, whether congenital or acquired, are often called fistulas. The term is used in medicine, biology, mycology, geology, and geography. Etymology Anastomosis: medical or Modern Latin, from Greek ἀναστόμωσις, anastomosis, "outlet, opening", Greek ana- "up, on, upon", stoma "mouth" ...

Robert Edward Gross
Robert Edward Gross (July 2, 1905 – October 11, 1988) was an American surgeon and a medical researcher. He performed early work in pediatric heart surgery at Boston Children's Hospital. Gross was president of the American Association for Thoracic Surgery, a member of the National Academy of Sciences and a fellow of the American Academy of Arts and Sciences. Biography The National Academies Press called him "one of America's great pioneers of surgery". ''The New York Times'' said that he did "pioneering work in the field of cardiac surgery". According to his obituary in ''The New York Times'', in 1938 Gross "performed the first surgical correction of one of the most common congenital heart disorders in children", referring to the ligation of the patent ductus. Ten years later he performed the first surgery to graft artery tissue from one person into another, thus making a leap in methods of repairing of damaged arteries. He also developed a method of cutting into a heart with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patent Ductus Arteriosus
Patent ductus arteriosus (PDA) is a medical condition in which the ''ductus arteriosus'' fails to close after childbirth, birth: this allows a portion of oxygenated blood from the left heart to flow back to the lungs from the aorta, which has a higher blood pressure, to the pulmonary artery, which has a lower blood pressure. Symptoms are uncommon at birth and shortly thereafter, but later in the first year of life there is often the onset of an increased work of breathing and Failure to thrive, failure to gain weight at a normal rate. With time, an uncorrected PDA usually leads to pulmonary hypertension followed by right-sided heart failure. The ''ductus arteriosus'' is a Fetal circulation, fetal blood vessel that normally closes soon after birth. This closure is caused by vessel constriction immediately after birth as circulation changes occur, followed by the occlusion of the vessel’s lumen in the following days. In a PDA, the vessel does not close, but remains ''patent'' (ope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vivien Thomas
Vivien Theodore Thomas (August 29, 1910 – November 26, 1985) was an American laboratory supervisor who, in the 1940s, played a major role in developing a procedure now called the Blalock–Thomas–Taussig shunt used to treat blue baby syndrome (now known as cyanotic heart disease) along with surgeon Alfred Blalock and cardiologist Helen B. Taussig. He was the assistant to Blalock in Blalock's experimental animal laboratory at Vanderbilt University in Nashville, Tennessee, and later at Johns Hopkins University in Baltimore, Maryland. Thomas was unique in that he did not have any professional education or experience in a research laboratory; however, he served as supervisor of the surgical laboratories at Johns Hopkins for 35 years. In 1976, Johns Hopkins awarded him an honorary doctorate and named him an Instructor of Surgery for the Johns Hopkins School of Medicine. Without any education past high school, Thomas rose above poverty and racism to become a cardiac surgery pi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alfred Blalock
Alfred Blalock (April 5, 1899 – September 15, 1964) was an American surgeon most noted for his work on the medical condition of shock as well as tetralogy of Fallot – commonly known as blue baby syndrome. He created, with assistance from his research and laboratory assistant Vivien Thomas and pediatric cardiologist Helen Taussig, the Blalock–Thomas–Taussig shunt, a surgical procedure to relieve the cyanosis from tetralogy of Fallot. This operation ushered in the modern era of cardiac surgery. He worked at both Vanderbilt University and Johns Hopkins University, where he studied medicine and later served as chief of surgery. He is known as a medical pioneer who won various awards, including Albert Lasker Clinical Medical Research Award. Blalock was also nominated several times for the Nobel Prize in Medicine. Early life and education Blalock was born in Culloden, Georgia, the son of Martha "Mattie" (Davis) and George Zadock Blalock, a merchant. At the age of 14, he ...
