A case of Left Main Stenting

CASE HISTORY

  • This 75 year old lady presented with Ischaemic Heart Disease
  • Her angiogram showed severe Left Main disease
  • The attending physician recommended that she undergoes coronary bypass surgery
  • After discussion with her and family, they did not want surgery
  • She was therefore listed for Left Main stenting

CONCLUSION

  • Presently, left main stenting is performed in many centers around the world
  • It has very good mid to long term results
  • It is a viable alternative to coronary bypass surgery especially when the patient is not a good candidate for open heart operation/li>
  • However, since the left main supplies 2/3 of the blood supply to heart, it is potentially a higher risk procedure/li>
  • In experienced hands the success rate is high and complication rate is low
  • Intra-Vascular Ultrasound should be used during the procedure, this also requires reasonable amount of expertise/li>
