Key result
At 1-year follow-up, the Perimount Magna aortic bioprosthesis resulted in a significantly larger indexed effective orifice area (0.8 vs 0.67 cm2/m2) and lower pressure gradients compared to the St Jude Epic valve, with no difference in left ventricular mass regression.
Why the study?
Does the Perimount Magna aortic bioprosthesis improve 1-year hemodynamics compared to the St Jude Epic aortic bioprosthesis in patients undergoing isolated aortic valve replacement?
Observational (n=69)
No

Absolute Event Rate: 0.8% vs 0.67%
p-value: p=0.02
The Perimount Magna aortic bioprosthesis demonstrated superior 1-year hemodynamic profiles (lower gradients and larger indexed effective orifice area) compared to the St Jude Epic valve, though this did not translate to differences in left ventricular mass regression.
No takes yet. Share an insight, caveat, or question.
Perimount Magna was associated with superior 1-year hemodynamics; leaves open effects on outcomes and requires randomized confirmation.
Bobiarski et al. (2013) conducted an observational in Aortic valve disease requiring replacement (n=69). Perimount Magna aortic bioprosthesis vs. St Jude Epic aortic bioprosthesis was evaluated on Indexed effective orifice area (iEOA) at 1 year in cm2/m2 (p=0.02). At 1-year follow-up, the Perimount Magna aortic bioprosthesis resulted in a significantly larger indexed effective orifice area (0.8 vs 0.67 cm2/m2) and lower pressure gradients compared to the St Jude Epic valve, with no difference in left ventricular mass regression.
