Background. The efficacy of preoperative intraaortic balloon pump therapy in high-risk coronary patients has been demonstrated earlier.

Methods. This study investigates the economic aspect by a detailed cost analysis of pooled information from two previously published randomized studies and 144 consecutive low-risk coronary artery bypass graft operations. Costs for patients receiving preoperative intraaortic balloon pump therapy before aortic cross-clamping (n = 62) were compared to those in a control group (n = 50). Detailed cost analysis was based on data provided by the hospital finance department.

Results. The total hospital costs were as follows: low-risk coronary artery bypass graft operations cost 35,335 ± 1,694 Swiss francs ($23,400 ± $1,121); high-risk coronary artery bypass graft without preoperative intraaortic balloon pump therapy cost 65,892 ± 31,719 Swiss francs ($43,637 ± $21,006); and high risk coronary artery bypass graft with preoperative intraaortic balloon pump therapy cost 41,948 ± 10,379 Swiss francs ($27,780 ± $6,874) (p = 0.0015). There were no significant differences in average cost among the preoperative intraaortic balloon pump therapy subgroups.

Conclusions. Preoperative intraaortic balloon pump therapy in high risk coronary patients is significantly cost-beneficial, With an average saving of 24,000 Swiss francs ($16,000) on the total hospital cost, a 36% cost reduction.
