title: Temporary coronary artery perfusion catheter during minimally invasive coronary surgery.
abstract: OBJECTIVE
  The purpose of this study was to investigate the use of an intracoronary cannula during minimally invasive direct coronary artery bypass (MIDCAB) surgery.
  
  
  METHODS
  Evaluation of the coronary perfusion catheter was conducted during MIDCAB surgery to determine if there was any trauma to the coronary artery. The study was retrospective with 45% follow-up arteriograms.
  
  
  METHODS
  A community hospital provided the setting for the study. Twenty patients undergoing MIDCAB surgery were included.
  
  
  METHODS
  Insertion of an intracoronary cannula was performed during MIDCAB surgery.
  
  
  RESULTS
  Measurements were determined on 45% follow-up arteriograms, and clinical follow-up was done on patient status.
  
  
  CONCLUSIONS
  The use of an intracoronary cannula during MIDCAB surgery did not result in any trauma to the cannulated coronary artery. The cannula prevented ischemia of the service area of the target coronary artery. ECG changes were avoided as were hypotension and arrhythmias. The cannula also helped stabilize the target coronary area during suturing.
