History Flashcards
[year, person] discovered x-rays
1895, Roentgen
[year] x-rays of fractures had been obtained and published
1896
[person] observed the movements of the opaque mass in the stomach and subsequently mixing bismuth subnitrate described the nature and site of peristaltic activity in cats as seen on fluoro screen
Walter B. Cannon
[person, year] published the “The Rotgen Rays in Medical Work. New York:William Wood, [..]”
1898, Walsh
[person] reproduced a chest film that clearly showed the pos’n and dimensions of the heart and describe a no. of cardiac and aortic conditions that he visualized radiographically. exposure time:20m, tube 30 in (76 cm)
Walsh
[persons] published photograph of original roentgenogram that clearly showed the potential of the method for visualizing the vascular bed
Haschek and Lidenthal
[year, persons] introduced a suspension of bismuth and oil into the hearts of dogs and rabbits directly through the large veins and observed passage from heart to lungs
1910, Franek and Alwens
[year, person] a radiographic atlas devoted only to the systemic arteries of the body was pubished in England, “The X-rays atlas of the systemic arteries of the body. London: Balliere, Tindall, and Cox, [..],” by [..]
-Showed blood vessels in cadavers with great quality
1920, Orrin
[year, persons] used Lipidol, an early oil-based cm to study bronchial tree and the subarachnoid space
1922, Sicard and Forestier
[year, persons] injected 5ml of Lipidol into the femoral vein of a dog.
-Repeated on human subjects, patients coughed
1923, Sicard and Forestier
[year, persons] reported first arteriograms and venograms obtained in human subjects, using 20% strontium bromide
1923, Berberich and Hirsch
[year, person] described the intraarterial injection of sodium iodide as a means of showing vessels of the lower extremities in humans
1924, Brooks
[year, person] described carotid angiography and its application to the study of cerebral lesions.
1928, Edward Moniz
[date, person] remarked on his Nobel lecture, led us to a new understanding of cardiac function in humans
December 11, 1956, Andre Coutard
[year, person] performed and named cardiac catherization. The subject was a horse and both right and left ventricles were entered by retrograde approach from jugular vein and carotid artery
1844, Claude Bernard
[year, person] practiced on a cadaver, inserted a 65 cm catheter into his own antecubital vein until he felt that id had reached his right atrium
1928, Werner Forssmann
[year, person] reported 11 right heart catherizations, including passage to the right ventricle and measurement of cardiac output in two subjects
1932, Padillo and Coworkers
[year, persons] reported the firstretrograde left heart catherizations
1950, Zimmerman and others, Limon-Lason and Bouchard
[year, person] percutaneous technique was developed and soon applied to cardiac catherizations of both the left and right heart chambers
1953, Seldinger
[year, persons] trans-septal catherizations was first developed and quickly became accepted as a standard technique
1959, Ross and Cope
[year, persons] and [year, person]coronary angiography was modified for percutaneous approach
1962, Ricketts and Abrams
1967, Judkins
[year, persons] introduced a practical balloon-tipped, flow guided catheter technique enabling the application of catherization outside laboratory. Batter rad technique and less toxic contrast agents
1970, Swan and Ganz
[year, person] introduced the technique of Balloon Angioplasty known as Percutaneous Transluminal Coronary Angioplasty (PTCA)
1977 Gruntzig and others
