Ulrich Sigwart
Ulrich Sigwart (; born 9 March 1941) is a German retired cardiologist known for his pioneering role in the conception and clinical use of stents to keep blood vessels open, and introducing a non-surgical intervention, alcohol septal ablation for the treatment of hypertrophic obstructive cardiomyopathy. Sigwart received his medical degree in 1967 from the University of Münster before gaining his MD that same year from the University of Freiburg. In 1984, he performed the first coronary stent and 10 years later introduced percutaneous alcohol septal ablation, a non-surgical method for the treatment of hypertrophic obstructive cardiomyopathy, as an alternative to open heart surgery. Early life and education Ulrich Sigwart was born on 9 March 1941 in Wuppertal, Germany, the fifth child of August R. Sigwart, a Bayer Industries scientist, and his wife Elizabeth. He was an infant when his father died under suspicious circumstances in Nazi-occupied Europe. His family has its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wuppertal
Wuppertal (; ) is a city in North Rhine-Westphalia, in western Germany, with a population of 355,000. Wuppertal is the seventh-largest city in North Rhine-Westphalia and List of cities in Germany by population, 17th-largest in Germany. It was founded in 1929 by the merger of Elberfeld, Barmen, Ronsdorf, Cronenberg, Wuppertal, Cronenberg and Vohwinkel Schwebebahn, Vohwinkel, and was initially called "Barmen-Elberfeld" before adopting its present name in 1930. It is the capital and largest city of the Bergisches Land. The city straddles the densely populated banks of the River Wupper, a tributary of the Rhine. Wuppertal is located between the Ruhr (Essen) to the north, Düsseldorf to the west, and Cologne to the southwest, and over time has grown together with Solingen, Remscheid and Hagen. The stretching of the city in a long band along the narrow Wupper Valley leads to a spatial impression of Wuppertal being larger than it actually is. The city is known for its steep slope ...

Interventional Cardiology
Interventional cardiology is a branch of cardiology that deals specifically with the catheter based treatment of structural heart diseases. Andreas Gruentzig is considered the father of interventional cardiology after the development of angioplasty by interventional radiologist Charles Dotter. Many procedures can be performed on the heart by catheterization. This most commonly involves the insertion of a sheath into the femoral artery (but, in practice, any large peripheral artery or vein) and cannulating the heart under X-ray visualization (most commonly fluoroscopy). The radial artery may also be used for cannulation; this approach offers several advantages, including the accessibility of the artery in most patients, the easy control of bleeding even in anticoagulated patients, the enhancement of comfort because patients are capable of sitting up and walking immediately following the procedure, and the near absence of clinically significant sequelae in patients with a normal ...

Angiography
Angiography or arteriography is a medical imaging technique used to visualize the inside, or lumen, of blood vessels and organs of the body, with particular interest in the arteries, veins, and the heart chambers. Modern angiography is performed by injecting a radio-opaque contrast agent into the blood vessel and imaging using X-ray based techniques such as fluoroscopy. With time-of-flight (TOF) magnetic resonance it is no longer necessary to use a contrast. The word itself comes from the Greek words ἀνγεῖον ''angeion'' 'vessel' and γράφειν ''graphein'' 'to write, record'. The film or image of the blood vessels is called an ''angiograph'', or more commonly an ''angiogram''. Though the word can describe both an arteriogram and a venogram, in everyday usage the terms angiogram and arteriogram are often used synonymously, whereas the term venogram is used more precisely. The term angiography has been applied to radionuclide angiography and newer vascular ima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bad Oeynhausen
Bad Oeynhausen () is a spa town on the southern edge of the Wiehengebirge in the district of Minden-Lübbecke in the Ostwestfalen-Lippe, East-Westphalia-Lippe region of North Rhine-Westphalia, Germany. The closest larger towns are Bielefeld (39 kilometres southwest) and Hanover (80 km east). History In the village of Bergkirchen, which belongs to Bad Oeynhausen, a wellspring sanctuary existed in pre-Christian (Saxon) times at the local crossing of the Wiehengebirge, which was replaced in the 9th century by a church. Today's church is a subsequent building. On the church and the downhill-situated Widukind spring plates explain this further. A few metres from the church a 13th-century timbered homestead can still be found. In 753 Pepin the Short, according to the Royal Frankish Annals, stopped over ''ad locum qui dicitur Rimiae'', so that Rehme is commonly accepted as the oldest part of town. The origin myth of Bad Oeynhausen relates that in 1745 a local farmer named Sültem ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Theodore Dotter
Charles Theodore Dotter (14 June 1920 – 15 February 1985) was a pioneering American radiologist who is credited with developing interventional radiology. Dotter, with his trainee Dr Melvin P. Judkins, described angioplasty in 1964. Dotter received a bachelor of arts degree in 1941 from Duke University. He went to medical school at Cornell, where he met his future wife, Pamela Beattie, a head nurse at New York Hospital. They married in 1944. He completed his internship at the United States Naval Hospital in New York State, and his residency at New York Hospital. Dotter invented angioplasty and the catheter-delivered stent, which were first used to treat peripheral arterial disease. It was Dotter who, in 1950, developed an automatic X-Ray Roll-Film magazine capable of producing images at the rate of 2 per second. On January 16, 1964, at Oregon Health and Science University Dotter percutaneously dilated a tight, localized stenosis of the superficial femoral artery (SFA) in an 8 ...

Andreas Gruentzig
Andreas Roland Grüntzig (25 June 1939 – 27 October 1985) was a German radiologist and cardiologist, with foundational interest, training and research in epidemiology and angiology. He is known for being the first to develop successful balloon angioplasty for expanding lumens of narrowed arteries. He was born in Dresden. Early life Andreas Roland Gruentzig was born in Dresden, Germany on 25 June 1939, shortly before the start of World War II. His father, Dr. Wilmar Gruentzig (1902–1945), was a secondary-school science teacher with a PhD in chemistry. Wilmar was conscripted into the meteorological service of the Luftwaffe during World War II. He presumably died during the war. His mother was Charlotta (née Zeugner) Gruentzig (1907-1995) and a teacher. His older brother was Johannes Gruentzig. After his birth in Dresden, in 1940 the family moved to the house of a relative in the small town of Rochlitz in western Saxony. After the war, Charlotta and her sons moved to Leipzig al ...

Internship (medicine)
A medical (or surgical) intern is a physician in training who has completed medical school and has a medical degree, but does not yet have a license to practice medicine unsupervised. Medical education generally ends with a period of practical training similar to internship, but the way the overall program of academic and practical medical training is structured differs depending upon the country, as does the terminology used (see medical education and medical school for further details). Australia In Australia, medical graduates must complete one year in an accredited hospital post before they receive full registration. This year of conditional registration is called the intern year. An Medical education in Australia#Internship, internship is not necessarily completed in a hospital at the same state as the graduate's medical school. Austria In Austria, the sixth and final year of medical school is called "Klinisch-praktisches Jahr" or "KPJ" (literally translated: clinical practi ...
