  4. 4. Contents <ul><li>Introduction </li></ul><ul><li>History </li></ul><ul><li>Evolution & Advancement </li></ul><ul><li>Procedure & Conduct </li></ul><ul><li>Types of Facilities </li></ul><ul><li>Physical Arrangement & Space Requirement </li></ul><ul><li>Equipment </li></ul><ul><li>Human Resource </li></ul><ul><li>Performance Evaluation </li></ul><ul><li>Quality Assurance </li></ul>
  5. 5. Introduction <ul><li>The Cardiac Catheterisation Lab is one of the Biggest Advances of this century in Cardiology. </li></ul><ul><li>The expansion & widespread application of this technology throughout the world today could hardly have been imagined by Wenner Frossman, when in 1929, he was the first to pass a catheter into the heart of a living person himself. </li></ul><ul><li>Procedures in the Cardiac Cath Lab have evolved from purely diagnostic & research techniques to potentially life-saving interventional procedure </li></ul>
  6. 6. How It All Began ! <ul><li>1941 – Right Heart Catheterisation in Humans to study cardiac physiology </li></ul><ul><li>1950 – First retrograde left heart catheterisation, by Zimerman & co-workers </li></ul><ul><li>1950s(Late) – Advent of selective coronary angiography </li></ul><ul><li>1960s(Late) – Development of aorto-pulmonary bypass surgery </li></ul>
  7. 7. <ul><li>1970 – Balloon tipped flow directed catheters introduced by Swan & Ganz </li></ul><ul><li>1977 – Percutaneous transluminal balloon angioplasty, by Gruntzig </li></ul><ul><li>1970s(Late) – Dr. Mason Sones introduced Brachial approach. </li></ul><ul><li>Safe & expeditious catheterisation from femoral route- Dr Judkins & Amplatz </li></ul>How It All Began !
  8. 8. & Here We Are ! <ul><li>In the 1980s , the scope of interventional Cardiology increased with the introduction of new therapeutic modalities( Valvuloplasty,Stent etc. ) </li></ul><ul><li>ACC/AHA guidelines for Cardiac Catheterisation Labs published in 1991 </li></ul><ul><li>Cath Labs have now evolved into multipurpose facilities, by performing ‘non-cardiac’ vascular investigations involving peripheral, renal & carotid vasculature. </li></ul>
  9. 9. How It Works ! <ul><li>Cardiac Catheterisation is the insertion & passage of small plastic tubes ( catheters ) into the arteries & veins upto the heart to obtain X-ray pictures of coronary arteries & cardiac chambers as well as to measure pressures in the heart ( intra-cardiac haemodynamics ) </li></ul><ul><li>Locate & identify irregularities within the heart & its vasculature, in the aorta ad venacava and to define size & severity of the lesions. </li></ul>
  10. 11. Procedures 1. Diagnostic <ul><li>Coronary Angiogram </li></ul><ul><li>Right & Left heart Catheterisation </li></ul><ul><li>Electrophysiological Procedures </li></ul><ul><li>Intravascular Ultrasound </li></ul>2. Therapeutic <ul><li>Coronary angioplasty with stenting </li></ul><ul><li>Rotablator Atherectomy </li></ul><ul><li>Percutaneous Transluminal Valvuloplasty </li></ul><ul><li>Pacemaker Implantation </li></ul><ul><li>Implantation of Cardioverter Defibrillator </li></ul><ul><li>Retrieval of Broken Catheters </li></ul><ul><li>Deployment of various devices for closure of septal defects </li></ul><ul><li>Laser Angioplasty </li></ul>
  11. 12. Conduct Patient Preparation Informed Consent from patient/guardian Strictness of Sterile Techniques Special Clothing For workers Hepatitis B vaccination for Employees Following SOP Adequate post-procedural Holding area, proper nursing care and monitoring
  12. 13. Types of facilities ! <ul><li>Hospital-Based Labs with in-house thoracic surgical programmes </li></ul><ul><li>In-Hospital labs without Cardiac surgery capability </li></ul><ul><li>Free Standing Labs </li></ul><ul><li>Mobile Labs </li></ul>
  13. 14. Goals of Free-standing / Mobile Labs <ul><li>To reduce cost </li></ul><ul><li>Convenience of Location </li></ul><ul><li>Used in case of low-risk patients </li></ul><ul><li>Mostly used for diagnostic purposes. </li></ul>However the setting up of such labs is still controversial and a matter of debate
  14. 15. Design Elements The following facilities are required when the cath lab is a stand-alone entity <ul><li>Main Divisions </li></ul><ul><li>Procedure Room – Should be constructed to contain radiation and provide electrical safety </li></ul><ul><li>Control/Console Room – Should be of a size & configuration to allow ready and unencumbered access to X-ray controls, image recording devices ( video tapes, discs and digital controls) and physiological monitors & recorders </li></ul><ul><li>Equipment Rooms – Proper temperature control for computers and data storage </li></ul><ul><li>Clean Utility Room – For clean & sterile supplies and disposables </li></ul>
  15. 16. Other Important Facilities 5. Patient Holding Room ( preferably equipped with ECG monitors ) 6. Patient Recovery Room 7. Technician’s Work Room 8. Dark room for 35mm film ( if necessary ) 9. Chemistry Lab ( for blood gas analysis ) or Electrophysiology Labs 10. Scrub Facilities 11. Storage space for case carts 12.

  24. 25. Precious Human Resource # Chief Cardiologist # Assistant Angiographer # Laboratory Director # Cardiovascular Trainee # Nursing Personnel - Scrub Nurse Float/Circulating Nurse # Technical Staff – Radiation Technologist Radiation Physicist Lab Technologist Dark Room Technician Computer Technician Monitoring Technician # Non-Technical Staff – Medical Transcriber Clerks, Aides
  25. 26. Precious Human Resource The department staff is responsible for procuring necessary supplies as well as preparing the room and the patient before the procedure and for monitoring patient’s recovery. Important Qualification and Experience are of prime importance while recruiting personnel for the cardiac catheterisation laboratory All members of catheterisation team must complete a basic course in CPR
  26. 27. Radiation Safety Radiation Exposure Recommendations <ul><li>Measuring Radiation Exposure </li></ul><ul><li>Film Badges </li></ul><ul><li>Thermo-Luminescent Dosimeter ( TLD ) badge </li></ul><ul><li>Dosimeter badge should be worn with the front of the badge in direct line </li></ul><ul><li>of the scattered x-rays. </li></ul>Average background radiation exposure - 0.1 rem/year Average operator exposure ( per procedure ) - 0.004-0.016 rem Maximum Annual exposure for Medicos - 5 rem/year Maximum Lifetime exposure for medicos - 1 rem x Age
  27. 28. Administrative Issues Utilization levels Lab performance Evaluation Quality Assurance
  28. 29. Utilisation Levels <ul><li>Laboratory </li></ul><ul><li>For optimum lab performance & cost-effectiveness – </li></ul><ul><li>Adult Studies – Min. caseload of 300/year </li></ul><ul><li>Paediatric Studies – Min. 150 cases/year </li></ul><ul><li>2) Physician- Operator </li></ul><ul><li>For adequate performance & preventing excessive radiation exposure – </li></ul><ul><li>Individual physician – About 150 cases/year </li></ul><ul><li>Paediatric Physician – 50-100 cases/year </li></ul><ul><li>PTCA - 50 cases/year </li></ul><ul><li>Electrophyiological Studies – 100 cases/year </li></ul>
  29. 30. Lab Performance Evaluation Laboratory Safety and Efficiency is measured by – 1. Complication Rates ( through records ) 2. No. of studies that must be repeated because of inadequate data or image quality. Indicators Deaths related to catheterisation - < 0.1-0.2% <ul><li>To Limit Complications, Ensure : </li></ul><ul><li>Stringent Credentials for training and experience </li></ul><ul><li>Regular performance review </li></ul>

  31. 32. ReCeNt tReNdS <ul><li>Increase in Community Hospitals without CV surgical backup and free standing laboratories </li></ul><ul><li>Decline in risks associated with diagnostic & interventional cardiac catheterisation </li></ul><ul><li>Cinefilms being replaced by compact discs & computerised archiving system </li></ul><ul><li>Evolution of paediatric cardiac cath. from purely diagnostic to interventional lab. </li></ul>
  32. 33. Think About ….. Fluctuation of Patient load on a day to day basis Long Break-Even Point Market Competition
