  1. A potted history of cardiac surgery Chris Munsch Yorkshire Heart Centre, Leeds

  2. Christian Bilroth 1897 • “Surgery of the heart has probably reached the limits set by nature to all surgery…” • “Any surgeon who wishes to preserve the respect of his colleagues would never attempt to suture the heart”

  3. DanielHale-Williams, 1893

  4. Problems and solutions (1) • Surgery on the heart will impair the circulation • Use a temporary artificial circulation • The lungs get in the way • Use temporary artificial oxygenation • Cardiopulmonary bypass

  5. Problems and solutions (2) • The heart is full of blood, it beats and is difficult to operate on. • Cross clamp the aorta and deprive the heart of its blood supply

  6. Problems and solutions (3) • The beating heart will only tolerate 15 minutes of ischaemia at normothermia • Arrest the heart and make it hypothermic, and preserve its energy supplies • Hypothermic cardioplegic arrest

  7. 1977 - 2003 1977

  8. Its not all about us!

Joseph Priestley – 1733 -1804 • Born in Birstall Leeds. • Linguist,anatomist, astronomist, grammarian,, historian, preacher and scientist. • Identified new gas as an element and named it “Oxygen” also identifying eight distinct gases in air • Blamed for the Priestley Riots in Birmingham due to his support for French and American revolutions.
