Abstract
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. Methods: We reviewed 31 consecutive patients ≥≥90 years of age who underwent BAV at our institution from July 2003 to August 2006 for data pertinent to patient characteristics, procedural techniques, and 30‐day outcomes. Results: Our patients had a mean age of 93 ± 3.0 years (90–101). The society of thoracic surgery risk score was 18.5 (±10.2) and logistic Euroscore was 35.8 (±19.3). Twenty‐five patients (81%) underwent retrograde BAV and 6 (19%) antegrade BAV. Five patients (16%) underwent combined BAV and coronary stenting. Overall mean aortic valve area increased from 0.52 cm2 (±0.17) to 0.92 cm2 (±0.22) and mean New York Heart Association (NYHA) functional class improved from 3.4 to 1.8. Intraprocedural mortality occurred in one patient (3.2%) and 30‐day mortality in three patients (9.7%). Conclusions: BAV can be carried out in high risk nonagenarian patients with an acceptable complication rate, low perioperative mortality, and early improvement in NYHA functional class.
