Balloon aortic valvuloplasty for aortic stenosis using a novel percutaneous dilation catheter and power injector.

Calcific aortic stenosis is the most common valvular heart disease in the Western world. Although definitive treatment is valve replacement, many patients are not replacement candidates due to high surgical risk from older age and comorbid illness or lack of desire for a surgical or replacement procedure. Percutaneous balloon aortic valvuloplasty (BAV) is an option for palliative treatment in nonsurgical patients, although this procedure is complicated during the immediate postprocedure period by bleeding requiring transfusion for about 1 in 5 patients and subsequent restenosis.
