Retrograde balloon aortic valvuloplasty with the newly invented Inoue balloon for aortic stenosis accompanied by severe heart failure: a case report

Balloon aortic valvuloplasty (BAV) is frequently utilized for selected high-risk patients who cannot be immediate candidates for transcatheter aortic valve replacement. We describe a case of high-risk retrograde BAV performed safely with a newly invented Inoue balloon with stable fixation and multistage inflation characteristics, without any rapid ventricular pacing requirements.
