Coronary Intervention



  Percutaneous Coronary Intervention

A catheter-based therapy in which a blocked artery is opened using one or several of six different tools. All are delivered by means of a tube inserted in the femoral artery (at the groin) and advanced to the mouth of the artery. Following are the tools:



Angiojet

  • A catheter* that suctions clot out of an artery or coronary graft

Balloon Angioplasty

  • Compacts plaque to create a larger, approximately normal coronary channel

Brachytherapy

  • Delivering low grade radiation to a treated segment of coronary artery to prevent recurrence of scar formation

       

Cutting Balloon

  • A balloon with micro blades that scores the plaque and relaxes it as it is compacted by the balloon

Laser

  • A catheter* consisting of aligned optical fibers that delivers colder laser energy to plaque or clot and vaporizes it into CO2 (carbon dioxide) and water

Rotoblator

  • A device that polishes hard, calcified plaque off the inner wall of a coronary artery to enlarge the channel

* a catheter is a tube directed into a coronary artery without surgery that then delivers some form of energy to modify or remove plaque.
