Feasibility of transcatheter intervention for severe aortic stenosis in patients >or=90 years of age: aortic valvuloplasty revisited.

Objectives: The goals of this study were to determine the feasibility, safety, and early outcomes of balloon aortic valvuloplasty (BAV) for severe aortic stenosis in a nonagenarian population.

Background: This very elderly population is expanding rapidly, has a high incidence of aortic stenosis, and uncommonly undergoes surgical aortic valve replacement. These patients may best be treated with a transcatheter approach due to comorbidities, surgical risk, and personal preference.

Radiation following percutaneous balloon aortic valvuloplasty to prevent restenosis (RADAR pilot trial).

Objectives: We wished to determine the feasibility and early safety of external beam radiation therapy (EBRT) used following balloon aortic valvuloplasty (BAV) to prevent restenosis.

Background: BAV for calcific aortic stenosis (AS) has been largely abandoned because of high restenosis rates, i.e.
