OBJECTIVES: The aim of the study was to describe a new technique to minimize requirement of contrast and the time to puncture the axillary vein during implantation of cardiac resynchronization therapy (CRT) devices. BACKGROUND: One of the challenges to the wide applications of CRT has been the technical difficulty encountered while obtaining venous access utilizing axillary venous puncture. This is mainly due to vague anatomical land marks. The axillary vein is the preferred access point because of fewer associated risks and better lead protection in the future. METHODS: We introduced a 0.035 mm guidewire retrogradely from the femoral vein up to the left axillary vein. A single anteroposterior scene at 7.5 frames/second was captured while the guidewire was in the vein. The scene was kept as a roadmap for the axillary vein puncture during the implantation procedure. RESULTS: The axillary vein was accessed in all patients (100%) and the time to axillary vein puncture was <1 minute in 36 patients (41%) and between 1-5 minutes in the remaining patients. There were no related vascular complications and no contrast venography was required. CONCLUSION: The use of retrograde axillary vein wiring simplifies axillary venous puncture and minimizes the need for contrast media during CRT device implantation without compromising visualized anatomy.
