This brief timeline is intended to give an overview of the history of interventional cardiology. More in-depth information can be accessed through the links provided, as well as from the reference sources listed at the bottom of the page.

* 3000 B.C. — Egyptians perform bladder catheterizations using metal pipes.

* 400 B.C. — Catheters fashioned from hollow reeds and pipes are used in cadavers to study the function of cardiac valves.

Hales performs catheterization on horse
* 1711 — Hales conducts the first cardiac catheterization of a horse using brass pipes, a glass tube and the trachea of a goose.

* 1844 — French physiologist Bernard coins the term "cardiac catheterization" and uses catheters to record intracardiac pressures in animals.

Werner Forssmann performs self-catheterization
* 1929 — First documented human cardiac catheterization is performed by Dr. Werner Forssmann in Eberswald, Germany. (Click to see video)

* 1941 — Cournand and Richards employ the cardiac catheter as a diagnostic tool for the first time, utilizing catheter techniques to measure cardiac output.


* 1956 — Forssmann, Cournand and Richards share the Nobel Prize. Cournand states in his acceptance speech "the cardiac catheter was...the key in the lock."

Mason Sones at Cleveland Clinic
* 1958 — The diagnostic coronary angiogram — the key to selective imaging of the heart is discovered by Dr. Mason Sones


* Charles Dotter 1964 — Transluminal Angioplasty, the concept of remodeling the artery, is introduced by Dr. Charles T. Dotter

* 1967 — Dr. Rene Favaloro conducts first saphenous vein graft (bypass) surgery in Cleveland

Melvin Judkins in lab

* 1974 — Andreas Gruentzig performs first peripheral human balloon angioplasty

Gruentzig's Poster Exhibit at 1976 AHA
* 1976 — Gruentzig presents results of animal studies of coronary angioplasty at American Heart Association meeting


* 1st intraoperative angioplasty performed in San Francisco 1977 — First human coronary balloon angioplasty performed intraoperatively by Gruentzig, Myler and Hanna in San Francisco


* before / after of 1st PTCA patient 1977 — Andreas Gruentzig performs first cath lab PTCA on awake patient in Zurich; starting with this case, all PTCA data is entered into a worldwide registry


* Myler, Stertzer and Gruentzig in Zurich 1978 — First PTCA cases performed in America by Myler in San Francisco and Stertzer in New York; Gruentzig conducts first demonstration course in Zurich, Switzerland, attended by 28 pioneering physicians; International Dilatation Society is established


* Last PTCA course (1980) in Zurich 1980 — Gruentzig conducts the last of five demonstration courses in Zurich with Sones, Judkins and Dotter in attendance; he then moves to Atlanta, GA where be becomes Director of Interventional Cardiology at Emory University; National Heart, Lung & Blood Institute begins support of the existing PTCA registry; first 1000 angioplasties are performed worldwide; guiding catheters are introduced



* 1982 — over-the-wire coaxial balloon systems introduced, brachial guiding catheters & steerable guide wires are developed

* 1985 — A year of loss in the history of interventional medicine: Dotter, Sones, Judkins and Gruentzig all pass away nine months of each other; Gruentzig dies in a plane crash on Sunday night, October 27; on Monday, October 28, Richard Schatz, co-inventor of the Palmaz-Schatz stent, has an appointment to meet with Gruentzig

* 1986 — coronary atherectomy devices are introduced; Jacques Puel and Ulrich Sigwart implant the first coronary Wallstents in Toulose, France

IVUS imaging
* 1987-1993 — a large number of new interventional devices are invented and perfected; some, like lasers, are less effective than hoped for; others are approved and used worldwide; these devices include rotational atherectomy devices (Rotablator), intravascular ultrasound (IVUS) and stents

* 1994 — the Palmaz-Schatz stent is approved by the F.D.A. for use in the United States

* 1994-1997 — stents become commonplace and eliminate many complications

* 2001 — almost two million angioplasties were performed worldwide, with an estimated increase of 8% annually

* 2002 — the 25th anniversary of the first angioplasty performed in an awake patient

* 2003 — the first drug-eluting stent, the Cypher, manufactured by Johnson & Johnson / Cordis, is approved by the F.D.A., marking a major advance in the battle to reduce restenosis to single digits

* 2004 — Boston Scientific gets its Taxus drug-eluting stent approved; many studies are published demonstrating the vastly improved outcomes from drug-eluting stents

Answer 2

Coronary angioplasty, also known as "percutaneous transluminal coronary angioplasty (PTCA)", was first developed in 1977 by Andreas Gruentzig. The procedure was quickly adopted by numerous cardiologists, and by the mid-1980's, many leading medical centers throughout the world were adopting the procedure as a method to avoid bypass surgery.
