OBJECTIVES This study presents the largest clinical experience of percutaneously placed axillary intra-aortic balloon pump (IABP) in patients with advanced heart failure. BACKGROUND Transfemoral placement of IABP limits mobility and recuperation in patients who need prolonged support. We had previously reported a novel percutaneous method of IABP placement in the axillary artery and now present our expanded experience with this technique. METHODS We performed a retrospective chart review of patients with advanced heart failure with percutaneous axillary IABP placement from November 2007 to June 2018 at Houston Methodist Hospital. We defined successful cardiac replacement therapy as heart transplant or left ventricular assist device implantation. We compared patients who had successful cardiac replacement with those who died and those who needed unplanned escalation of mechanical circulatory support. RESULTS Of the 195 patients identified, 133 (68%) underwent successful cardiac replacement (120 transplants and 13 left ventricular assist device) as planned. End-organ function improved on IABP support in patients bridged to next therapy. There were 16 patients that died while on IABP support and 18 needed escalation of support. Higher right atrial/ wedge ratio, higher right atrial pressure, smaller left ventricular end diastolic dimension, and ischemic cardiomyopathy were associated with death on the IABP in multivariate analysis. Post-transplant and post left ventricular assist device survival for those bridged successfully was 87% and 62%, respectively. Although bedside repositioning was frequent, 37% needed replacement for malfunction. Vascular complications occurred in a minority. CONCLUSIONS Percutaneous axillary approach for IABP placement is a feasible strategy for prolonged mechanical circulatory support in patients with advanced heart failure.
