The device has been successfully applied to antegrade aortic valvuloplasty; the hourglass shape stabilizes the balloon across the aortic valve without rapid ventricular pacing. Subsequently, an Inoue balloon was developed for retrograde aortic valvuloplasty using the same design as the antegrade balloon. The hourglass\u2010shaped balloon, however, has difficulty maintaining stability across the aortic valve because the distal portion of the balloon, which inflates first, directly receives systolic pressure from the left ventricle. A novel Inoue balloon was invented to overcome this issue by altering the manner of inflation: the proximal portion inflates first, followed by the distal portion. Theoretically, the proximal portion, which initially inflates just above the aortic valve, remains secure across the valve by applying a pressing force that counteracts the systolic forward pressure. Furthermore, a radiopaque marker is placed at the center of the balloon to enable rapid and precise balloon adjustment. We present a case involving a 65\u2010year\u2010old female hemodialysis patient with severe symptomatic aortic stenosis who we successfully treated with balloon aortic valvuloplasty using the novel Inoue balloon followed by transcatheter aortic valve implantation. The present case demonstrates the feasibility and effectiveness of the novel \u201cproximal first\u201d Inoue balloon for retrograde balloon aortic valvuloplasty for severe aortic stenosis.<\/jats:p>","DOI":"10.1002\/ccd.30166","type":"journal-article","created":{"date-parts":[[2022,3,30]],"date-time":"2022-03-30T19:28:43Z","timestamp":1648668523000},"page":"2131-2135","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A
