The efficacy of short term Intra-aortic Balloon Pump (IABP) use has been recently put into question; however its use for extended support isn't well established. We previously demonstrated the safety and feasibility of the use of percutaneous Axillary IABP as bridge to orthotopic heart transplant (OHT) in HF patients. Our primary aim is to review the impact of extended IABP use in end-organ function and hemodynamics.
We retrospectively identified patients that underwent left axillary IABP implantation as a bridge to transplant strategy. Laboratory values and invasive hemodynamics were retrieved from the day before IABP implantation and from the day of OHT or removal. Paired student t-test was used and p values <0.05 considered significant.
A total of 44 patients were analyzed, 39 (89%) were successfully bridged to either heart or heart multi organ transplant. Three patients expired while on support and two underwent high risk LVAD implantation. Median days of support 17 with a range of 6-152 days. Overall there was a significant improvement in creatinine, BUN and total bilirubin and as well as a significant decrease in mean pulmonary artery pressure with slightly lower right atrial pressure.
Extended support with a percutaneous axillary IABP for patients with end-stage HF as a bridge to OHT was associated with improvement in end-organ function and pulmonary pressure. These findings support the prolonged use of axillary IABP in a select advanced HF population.
