Intra-Aortic Balloon Pump Catheter Insertion Using a Novel Left External Iliac Artery Approach in A Case of Chronic Heart Failure Due to Dilated Cardiomyopathy.

BACKGROUND The use of an intra-aortic balloon pump (IABP) in patients with advanced heart failure can provide interim mechanical support as a bridge to further treatment, including cardiac transplantation. The femoral artery, axillary artery, and subclavian artery are the main approaches to IABP catheter placement. A case is reported of the use of a left external iliac artery approach to IABP catheter placement using a subcutaneous channel in a patient with chronic heart failure. CASE REPORT A 67-year-old woman presented with a history of heart failure. She had New York Heart Association (NYHA) Functional Class IV symptoms. The patient had a history of chronic heart failure due to dilated cardiomyopathy with a left ventricular ejection fraction of 25%, severe mitral regurgitation, paroxysmal atrial fibrillation, and hypothyroidism. Immediate pharmacological treatment began, and an IABP catheter was initially inserted using femoral artery access. During 115 days of hospital treatment, several unsuccessful attempts were made to remove the IABP catheter. Due to prolonged patient immobility, the IABP catheter access was changed from the femoral artery to the external iliac artery. A prosthetic Dacron graft and a subcutaneous channel were used. Optimal pharmacotherapy commenced, and the patient underwent rehabilitation and mobilization with significant improvement in cardiac function. At 195 days after changing the IABP catheter access, the patient underwent successful heart transplantation. CONCLUSIONS This report demonstrated that in a patient with chronic heart failure requiring long-term femoral IABP catheter placement, an external iliac artery approach using a subcutaneous channel provided a bridge to cardiac transplantation.
