Title: Brief History of Cardiac Catheterisation


1
Brief History of Cardiac Catheterisation
  • Gemma C. Ryder
  • g.c.ryder_at_qmul.ac.uk

2
Intra-cardiac catheter
  • A thin tube passed to the heart via a vein or
    artery
  • Used to withdraw blood
  • Measure pressure in heart chambers or great
    vessels
  • Inject contrast media
  • For diagnosis and evaluation of congenital
    conditions and coronary artery lesions
  • To evaluate systolic and diastolic cardiac
    function

3
4 Major Events in CC History
  • Development of techniques for measuring
    intracardiac physiologic events in animals
  • Application of these techniques to humans
  • Development of coronary angiography
  • Development of catheter-based procedures

4
Early catheterisation 1
  •  In 1711, Stephen Hales conducted the first
    cardiac catheterisation of a horse using brass
    pipes, a glass tube and the trachea of a goose.

5
Early catheterisation 2
  •  In 1844, Claude Bernard inserted a mercury
    thermometer into a horse carotid artery
  • Early chemotherapy required the injection of
    drugs directly into the central circulation.
    Bleichroeder inserted catheters into dog arteries
    and assessed the effects after leaving them in
    place for several hours. He reported no
    complications or clots.

6
First catheterisation in a human
  • In 1929, a German surgical trainee, Werner
    Forssmann, experimented on a human cadaver and
    realized how easy it was to guide a urological
    catheter from an arm vein into the right atrium
  • In the early 1940's, Cournand, working in New
    York,began utilizing
  • right heart catheterisation on a regular basis in
    the undertaking of a
  • comprehensive investigation of cardiac function
    in both normal and
  • diseased patients

7
Development of catheterisation
  • 1953 Seldinger developed a percutaneous approach
    for the introduction of catheters for both right
    and left heart catheterisation
  • In the 1950's, diagnostic catheterisation became
    established as the best method for confirmation
    of clinical findings prior to cardiac surgery for
    valvular or congenital heart disease.

8
Vascular Access
  • Prior to Seldinger vascular access via cutdown
  • Complications
  • Haemorrhage
  • Infection
  • Acute thrombosis
  • Distal embolisation

Cut Down
10
Seldinger Technique
  • Inject local anaesthetic
  • Locate artery
  • Puncture with 18G needle
  • Advance guidewire thru into artery
  • Remove needle and advance introducer sheath

Complications of Seldinger Technique
  • Haemorrhage
  • AV fistula
  • Dissection
  • Embolism/Thrombosis
  • Closure
  • Manual compression
  • Closure devices

Complications of Catheterisation
  • Thrombosis
  • Extrinsic - catheter material
  • Heparin
  • PTFE, coatings
  • Intrinsic - endothelial damage
  • Catheter design

17
Coronary Angiography
  • 1958 Accidental discovery by Sones
  • Involves injecting contrast agent into the
    coronary arteries
  • Cine-angiography
  • X-ray images taken in rapid succession to capture
    the dyes progression

Catheter-based procedures
  • Valvuloplasty to open stenotic valves
  • Pacemaker implantation
  • Angioplasty 1974 peripheral/1977 coronary
  • Atherectomy
  • Lasers
  • Stents

24
Catheter based interventions are now very common
  • 1997 over one million angioplasties performed
    worldwide, making angioplasty the most common
    medical intervention in the world
  • 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
