The use of intra-aortic balloon pump in patients undergoing heart valve replacement: outcome and risk analysis
Insights
Intra-aortic balloon pump (IABP) use in heart valve surgery patients has high mortality. Intraoperative IABP insertion improves outcomes compared to postoperative use, especially for older patients or those with pulmonary hypertension.
Area of Science:
- Cardiovascular Surgery
- Critical Care Medicine
- Medical Devices
Background:
- Intra-aortic balloon pump (IABP) use in heart valve surgery is linked to increased mortality.
- Coronary artery bypass grafting (CABG) is associated with lower mortality in these patients.
- Early outcomes and risk factors for mortality in IABP-supported heart valve patients require detailed analysis.
Purpose of the Study:
- To analyze the early outcomes of heart valve surgical patients requiring IABP support.
- To identify risk factors associated with early mortality in this patient cohort.
- To compare the efficacy of intraoperative versus postoperative IABP insertion.
Main Methods:
- Retrospective analysis of 81 patients (1.4%) who required IABP support during heart valve replacement without CABG.
- Application of univariate and multivariate logistic regression to identify mortality risk factors.
- Comparison of mortality rates between intraoperative and postoperative IABP subgroups.
Main Results:
- Overall mortality in IABP patients was 50.6%.
- Intraoperative IABP insertion (26.7% mortality) showed significantly lower mortality than postoperative insertion (64.7%).
- Independent risk factors for mortality included older age (OR 1.906) and pulmonary hypertension (OR 4.153); intraoperative IABP was protective (OR 0.297).
Conclusions:
- Heart valve replacement patients requiring IABP support face high early mortality.
- Intraoperative IABP insertion demonstrates superior efficacy compared to postoperative use.
- Older patients and those with pulmonary hypertension require careful consideration due to potentially poorer IABP outcomes.
Background And Aim Of The Study:
Intra-aortic balloon pump (IABP) in heart valve surgical patients is associated with a higher mortality than coronary artery bypass grafting (CABG). The study aim was to analyze the early outcome of heart valve surgical patients requiring IABP support, and to assess the risk factors for early mortality.
Methods:
Among a cohort of 5,786 patients undergoing heart valve replacement without CABG, 81 (1.4%) required IABP support. Data from these latter patients were collected and analyzed retrospectively, and univariate and multivariate logistic regression were applied to identify risk factors for early mortality in patients requiring IABP support.
Results:
IABP was inserted in 30 patients intraoperatively, and in 51 patients postoperatively. The overall mortality was 50.6%. Mortality in the intraoperative IABP subgroup was significantly lower than in the postoperative IABP subgroup (26.7% versus 64.7%, p = 0.001). The independent risk factors for early mortality were: age increasing by 10 years (OR 1.906, 95% CI: 1.165-3.116, p = 0.010) and pulmonary hypertension (OR 4.153, 95% CI: 1.380-12.499, p = 0.011). Intraoperative IABP insertion (OR 0.297, 95% CI: 0.100-0.876, p = 0.028) was identified as a protective factor compared to postoperative insertion.
Conclusion:
The mortality of patients requiring IABP support after heart valve replacement was high. The efficacy of intraoperative IABP insertion was better than a postoperative mandatory use. Clearly, more attention should be paid to older patients or those with pulmonary hypertension, who may benefit less from IABP.
