History of Angioplasty and PCI DevicesHistory of Angioplasty and PCI DevicesHistory of Angioplasty and PCI DevicesHistory of Angioplasty and PCI Devices

•3000 B.C. – Ultra-thin metal pipes employed by Egyptians to perform bladder catheterizations

•400 B.C. – Hollow reeds and pipes used as catheters to study function of cardiac valves in cadavers

•1711 – Hales performs the first cardiac catheterization on a horse using brass pipes, a glass tube

and the trachea of a goose

•1844 – French physiologist Bernard coins the term “cardiac catheterization” and

employs catheters to record intra-cardiac pressures in animals

•1929 – Dr. Werner Forssmann performs the first documented human cardiac catheterization

in Germany

•1941 – Two physicians at Columbia University, André Cournand and Dickinson Richards,

use the cardiac catheter as a diagnostic tool to measure cardiac output

•1956 – Forssmann, Richards and Cournand receive the Nobel Prize with Cournand

noting that the “cardiac catheter was. . . the key in the lock.”

•1958 – Dr. Mason Sones of the Cleveland Clinic conducts an imaging procedure of a child’s

aortic valve, accidentally engaging the right coronary artery and injecting dye. When the patient’s heart did not display the expected fibrillation, Sones realized he had discovered the key to selective imaging of the heart – the diagnostic coronary angiogram.

•1964 – Dr. Charles Dotter with Dr. Melvin Judkins introduces the concept of remodeling arteries, known as

transluminal angioplasty, by applying the earlier findings to open blocked peripheral arteries with atherosclerosis

•1967 – Dr. Rene Favaloro performs the first saphenous vein graft (bypass) surgery

•1967 – Judkins creates his own system of diagnostic imaging, introducing a series of

specialized catheters and perfecting the transfemoral approach (introducing the catheter via

a groin puncture rather than the more complex procedure used by Sones of introducing the catheter via

surgical opening of the brachial artery in the arm)

•1974 – Dr. Andreas Gruentzig performs the first human peripheral balloon angioplasty

•1976 – Gruentzig presents the results of animal studies involving coronary angioplasty at the

American Heart Association meeting

•1977 – Gruentzig with Dr. Richard Myler performs the first human coronary angioplasty

intraoperatively during bypass surgery in San Francisco

•1977 – First cath lab balloon angioplasty performed on an awake patient by Gruentzig in Zurich,

and the first case entered into a worldwide registry

•1978 – Myler and Stertzer perform the first US PTCA cases
