Influence of Age on Longevity of a Stentless Aortic Valve.

ABSTRACT:

Background

The longevity of a stentless valve in a younger population (20-60 years old) is unknown.

Methods

From 1992 to 2015, 1947 patients underwent aortic valve/root replacement for aortic stenosis, insufficiency, root aneurysm, or aortic dissection with stentless bioprostheses (median size, 26 mm). At operation 105 patients were <40 years old, 528 were 40 to 59, 860 were 60 to 74, and 454 were ≥75 years. The data were obtained through chart review, administered surveys, and the National Death Index.

Results

The 30-day mortality rate was 2.6%. During follow-up 807 patients (41%) died before reoperation, 993 (51%) were alive without reoperations because of deterioration, and 113 patients (5.8%) underwent reoperation for structural valve deterioration. After adjustin
