Transcatheter aortic valve implantation was performed on a 78-year-old patient. Elective circulatory support with cardiopulmonary bypass was planned because of left ventricular function impairment and hemodynamic instability. Limited vascular access was due to a severe atherosclerotic aorta distal to the origin of the left carotid artery. The right arm was the only safe vascular access site. However, at least 2 vascular access sites for angiographic catheter and inflow of circulatory support were required. An arterial inflow line equipped with a side arm was developed to enable single access to the right axillary artery to be used for the above purposes.
