Key result
Stentless aortic valves yield ~17% lower LVMI at 6 months vs conventional stented bioprostheses.
Why the study?
The study aimed to evaluate left ventricular hypertrophy and its regression after stentless versus conventional biological aortic valve replacement.
Does stentless aortic valve replacement improve left ventricular hypertrophy regression compared to conventional stented bioprosthesis in patients requiring aortic valve replacement?
RCT (n=180)
Randomized
Does stentless aortic valve replacement improve left ventricular hypertrophy regression compared to conventional stented bioprosthesis in patients requiring aortic valve replacement?
Absolute Event Rate: 141% vs 170%
p-value: p=<0.05
Stentless aortic valve implantation significantly enhances the regression of left ventricular hypertrophy at 6 months compared to conventional stented bioprostheses.

May guide stentless valve selection in AVR patients with marked LVH; extends RCT evidence to prosthesis-specific mass regression.
Walther et al. (1999) conducted an RCT in Aortic stenosis (n=180). Stentless aortic valve vs. Conventional stented bioprosthesis was evaluated on Left ventricular mass index at 6 months (p=<0.05). Stentless aortic valve replacement significantly enhanced the regression of left ventricular mass index at 6 months compared to conventional stented bioprostheses (141 vs 170 g/m2; P<0.05).
