title: The use of intra aortic baloon pump in patients undergoing coronary artery bypass grafting at the Aga Khan University Hospital, Karachi.
abstract: OBJECTIVE
  To review the experience in the use of Intra Aortic Balloon Pump (IABP) in patients undergoing Coronary Artery Bypass Grafting (CABG) at a tertiary care hospital with a new Open Heart surgery program.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  The Aga Khan University Hospital, Karachi.
  
  
  METHODS
  Medical records of all patients undergoing CABG between November 1994 and July 1997 were reviewed and those in whom IABP device was used, were included in this study.
  
  
  RESULTS
  A total of 15 patients had IABP support during the study period. Four surgeries were done urgently while two were emergencies. There were three mortalities. Ejection fractions in all but one patient were impaired. Among the surviving patients, the average pre-IABP Cardiac Index was 2.6 litres/min/meter2 which registered an average increase of 21.15% after the initiation of the IABP. The Pulmonary Artery Wedge Pressure also showed an average reduction of 29.11% from the pre IABP levels reflecting an increase in the cardiac output with the use of the IABP.
  
  
  CONCLUSIONS
  This series represents the early experience of a new cardiac surgery center in Pakistan in the use of IABP. Although the numbers in this study are too small to derive any conclusions, the overall morbidity and mortality in this short series are within acceptable limits in the high risk patients included.
