Walton Lillehei
Clarence Walton Lillehei (October 23, 1918 – July 5, 1999), was an American surgeon who pioneered open-heart surgery, as well as numerous techniques, equipment and prostheses for cardiothoracic surgery. Background Clarence (often called "Walt") Lillehei was born in Minneapolis, Minnesota, the son of Dr. Clarence Ingvald Lillehei (1892-1973) and Elizabeth Lillian (Walton) Lillehei (1891-1973). He attended West High School in Minneapolis in 1935. He attended the University of Minnesota at the age of 17. He earned 4 degrees at the University of Minnesota, including his B.S. (with distinction) in 1939, his M.D. (Alpha Omega Alpha) in 1942, his M.S. in physiology in 1951, and his Ph.D. in surgery in 1951. Career In 1944, Alfred Blalock at Johns Hopkins University Hospital had begun successfully performing surgery on the great vessels around the heart to relieve the symptoms of tetralogy of Fallot, demonstrating that heart surgery could be possible. Lillehei participated in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minneapolis, Minnesota
Minneapolis () is the largest city in Minnesota, United States, and the county seat of Hennepin County. The city is abundant in water, with thirteen lakes, wetlands, the Mississippi River, creeks and waterfalls. Minneapolis has its origins in timber and as the flour milling capital of the world. It occupies both banks of the Mississippi River and adjoins Saint Paul, the state capital of Minnesota. Prior to European settlement, the site of Minneapolis was inhabited by Dakota people. The settlement was founded along Saint Anthony Falls on a section of land north of Fort Snelling; its growth is attributed to its proximity to the fort and the falls providing power for industrial activity. , the city has an estimated 425,336 inhabitants. It is the most populous city in the state and the 46th-most-populous city in the United States. Minneapolis, Saint Paul and the surrounding area are collectively known as the Twin Cities. Minneapolis has one of the most extensive public par ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doctor Of Philosophy
A Doctor of Philosophy (PhD, Ph.D., or DPhil; Latin: or ') is the most common Academic degree, degree at the highest academic level awarded following a course of study. PhDs are awarded for programs across the whole breadth of academic fields. Because it is an earned research degree, those studying for a PhD are required to produce original research that expands the boundaries of knowledge, normally in the form of a Thesis, dissertation, and defend their work before a panel of other experts in the field. The completion of a PhD is often a requirement for employment as a university professor, researcher, or scientist in many fields. Individuals who have earned a Doctor of Philosophy degree may, in many jurisdictions, use the title ''Doctor (title), Doctor'' (often abbreviated "Dr" or "Dr.") with their name, although the proper etiquette associated with this usage may also be subject to the professional ethics of their own scholarly field, culture, or society. Those who teach at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artificial Pacemaker
An artificial cardiac pacemaker (or artificial pacemaker, so as not to be confused with the natural cardiac pacemaker) or pacemaker is a medical device that generates electrical impulses delivered by electrodes to the chambers of the heart either the upper atria, or lower ventricles to cause the targeted chambers to contract and pump blood. By doing so, the pacemaker regulates the function of the electrical conduction system of the heart. The primary purpose of a pacemaker is to maintain an adequate heart rate, either because the heart's natural pacemaker is not fast enough, or because there is a block in the heart's electrical conduction system. Modern pacemakers are externally programmable and allow a cardiologist, particularly a cardiac electrophysiologist, to select the optimal pacing modes for individual patients. Most pacemakers are on demand, in which the stimulation of the heart is based on the dynamic demand of the circulatory system. Others send out a fixed rate of ...

Catheterization
In medicine, a catheter (/ˈkæθətər/) is a thin tube made from medical grade materials serving a broad range of functions. Catheters are medical devices that can be inserted in the body to treat diseases or perform a surgical procedure. Catheters are manufactured for specific applications, such as cardiovascular, urological, gastrointestinal, neurovascular and ophthalmic procedures. The process of inserting a catheter is ''catheterization''. In most uses, a catheter is a thin, flexible tube (''soft'' catheter) though catheters are available in varying levels of stiffness depending on the application. A catheter left inside the body, either temporarily or permanently, may be referred to as an "indwelling catheter" (for example, a peripherally inserted central catheter). A permanently inserted catheter may be referred to as a "permcath" (originally a trademark). Catheters can be inserted into a body cavity, duct, or vessel, brain, skin or adipose tissue. Functionally, they all ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Morris J
The Morris Commercial J-type is a 10 cwt (0.5 ton) van launched by Morris Commercial in 1949 and produced until 1961. After the formation of the British Motor Corporation in 1952, by the merger of Morris' parent company, the Nuffield Organization, and Austin, the Commercial name was dropped and the van was marketed as the Morris J-type. The van followed the emerging trend of having forward controls and sliding doors on each side. It was made in both left and right hand drive versions. As well as complete vehicles, the J-type was also supplied in chassis form to external body makers and it appeared, amongst other uses, as a pick-up, tipper truck, ice cream van and milk float. Many were bought by the British Post Office and these differed from standard in having rubber front and rear wings. The J type is fitted with a 1476 cc four-cylinder side-valve engine based on the one used in the contemporary Morris Oxford MO car. Drive to the rear wheels is through a three-speed g ...

Litchfield, Minnesota
Litchfield is a city in and the county seat of Meeker County, Minnesota, United States. The population was 6,624 at the 2020 census. History Immigration to the county was slow until the St. Paul, Minneapolis and Manitoba Railroad, later the called St. Paul and Pacific and then the Great Northern, started coming through the area in 1869. The first train to arrive was a construction train on August 13, 1869. The town site was laid out in 1869 with agriculture and agriculture related industries making up a large base of the economy. The town's first post office opened in a home in September 20, 1869. It later moved to the northwest corner of Sibley Avenue and Second Street, to a clothing store owned by the town's first official postmaster. Town name The settlers living in the area that is now Litchfield, named their settlement Ness on April 5, 1858, after many of the first settlers’ home - the parish of ''Næs'' in the traditional region of Hallingdal, Norway.

Atrioventricular Canal
The proper development of the atrioventricular canal into its prospective components (The heart septum and associated valves) to create a clear division between the four compartments of the heart and ensure proper blood movement through the heart, are essential for proper heart function. When this process does not happen correctly, a child will develop atrioventricular canal defect which occurs in 2 out of every 10,000 births. It also has a correlation with Down syndrome because 20% of children with Down syndrome have atrioventricular canal disease as well. This is a very serious condition and surgery is necessary within the first six months of life for a child.Brown, David MD "Atrioventricular Canal Defect" Children's Hospital Boston 20120 http://www.childrenshospital.org/az/Site521/mainpageS521P0.html Half of the children who are untreated with this condition die during their first year due to heart failure or pneumonia.

Pneumonia
Pneumonia is an inflammatory condition of the lung primarily affecting the small air sacs known as alveoli. Symptoms typically include some combination of productive or dry cough, chest pain, fever, and difficulty breathing. The severity of the condition is variable. Pneumonia is usually caused by infection with viruses or bacteria, and less commonly by other microorganisms. Identifying the responsible pathogen can be difficult. Diagnosis is often based on symptoms and physical examination. Chest X-rays, blood tests, and culture of the sputum may help confirm the diagnosis. The disease may be classified by where it was acquired, such as community- or hospital-acquired or healthcare-associated pneumonia. Risk factors for pneumonia include cystic fibrosis, chronic obstructive pulmonary disease (COPD), sickle cell disease, asthma, diabetes, heart failure, a history of smoking, a poor ability to cough (such as following a stroke), and a weak immune system.

Congenital Defects
A birth defect, also known as a congenital disorder, is an abnormal condition that is present at birth regardless of its cause. Birth defects may result in disabilities that may be physical, intellectual, or developmental. The disabilities can range from mild to severe. Birth defects are divided into two main types: structural disorders in which problems are seen with the shape of a body part and functional disorders in which problems exist with how a body part works. Functional disorders include metabolic and degenerative disorders. Some birth defects include both structural and functional disorders. Birth defects may result from genetic or chromosomal disorders, exposure to certain medications or chemicals, or certain infections during pregnancy. Risk factors include folate deficiency, drinking alcohol or smoking during pregnancy, poorly controlled diabetes, and a mother over the age of 35 years old. Many are believed to involve multiple factors. Birth defects may be visib ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypothermia
Hypothermia is defined as a body core temperature below in humans. Symptoms depend on the temperature. In mild hypothermia, there is shivering and mental confusion. In moderate hypothermia, shivering stops and confusion increases. In severe hypothermia, there may be hallucinations and paradoxical undressing, in which a person removes their clothing, as well as an increased risk of the heart stopping. Hypothermia has two main types of causes. It classically occurs from exposure to cold weather and cold water immersion. It may also occur from any condition that decreases heat production or increases heat loss. Commonly, this includes alcohol intoxication but may also include low blood sugar, anorexia and advanced age. Body temperature is usually maintained near a constant level of through thermoregulation. Efforts to increase body temperature involve shivering, increased voluntary activity, and putting on warmer clothing. Hypothermia may be diagnosed based on either a person ...

Tetralogy Of Fallot
Tetralogy of Fallot (TOF), formerly known as Steno-Fallot tetralogy, is a congenital heart defect characterized by four specific cardiac defects. Classically, the four defects are: *pulmonary stenosis, which is narrowing of the exit from the right ventricle; * a ventricular septal defect, which is a hole allowing blood to flow between the two ventricles; * right ventricular hypertrophy, which is thickening of the right ventricular muscle; and * an overriding aorta, which is where the aorta expands to allow blood from both ventricles to enter. At birth, children may be asymptomatic or present with many severe symptoms. Later in infancy, there are typically episodes of bluish colour to the skin due to a lack of sufficient oxygenation, known as cyanosis. When affected babies cry or have a bowel movement, they may undergo a "tet spell" where they turn cyanotic, have difficulty breathing, become limp, and occasionally lose consciousness. Other symptoms may include a heart murmur, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
