Why the study?
Does a stentless aortic bioprosthesis improve left ventricular mass regression and hemodynamic performance compared to a stented bioprosthesis in elderly patients with aortic stenosis?
Does a stentless aortic bioprosthesis improve left ventricular mass regression and hemodynamic performance compared to a stented bioprosthesis in elderly patients with aortic stenosis?
In elderly patients with aortic stenosis, stentless bioprostheses do not provide superior left ventricular mass regression or hemodynamic benefits compared to stented bioprostheses at 1 year.
No takes yet. Share an insight, caveat, or question.
Stentless valves confer no LV mass or hemodynamic advantage over stented valves at 1 year; challenges prior non-randomized data in elderly aortic stenosis.
