Why the study?
Does a stentless bioprosthesis improve hemodynamic performance, left ventricular mass regression, and clinical outcomes compared to a stented bioprosthesis in elderly patients with aortic stenosis?
Does a stentless bioprosthesis improve hemodynamic performance, left ventricular mass regression, and clinical outcomes compared to a stented bioprosthesis in elderly patients with aortic stenosis?
In elderly patients with aortic stenosis, stentless bioprosthetic valves did not provide superior hemodynamic performance, left ventricular mass regression, or clinical outcomes compared to stented valves at 5 years.
No takes yet. Share an insight, caveat, or question.
No superiority of stentless over stented valves for LV mass or gradient at 5 years; confirms equivalence in elderly aortic stenosis.
Risteski et al. (2009) studied this question.
