An 84-year-old woman with aortic stenosis underwent antegrade balloon aortic valvuloplasty (BAV). After transseptal puncture, we introduced a 7-Fr wedge catheter into the left ventricle and across the aortic valve. We then inserted a 0.032-inch soft guide wire, and the tip of the guide wire was advanced into the brachial artery and exchanged for a stiff guide wire. We externalized the tip of the stiff guide wire from the radial artery. Finally, we advanced an Inoue balloon (Toray, Tokyo, Japan) across the aortic valve and inflated the balloon. Transradial externalization makes antegrade BAV an even less invasive procedure.
