Brief summary

The purpose of the study is to compare early and 1-year hemodynamic performance and clinical outcomes after aortic valve replacement using two pericardial bioprosthesis, Avalus and Carpentier Edwards Perimount Magna Ease.

Detailed description

This trial was designed as a multicenter randomized, controlled trial to recruit 386 patients who undergo aortic valve replacement with pericardial bioprosthesis. Patients were randomized by use of a randomization table. Bioprosthesis was chosen between Avalus or Carpentier Edwards Perimount Magna Ease according to the randomization result. The primary end point is postoperative 1-year transvalvular mean pressure gradient. The secondary end points are postoperative 1-year effective orifice area, operative mortality, operative morbidities, 1-year overall survival, 1-year freedom from cardiac death and 1-year freedom from valve-related events.

AVALUS GroupTransvalvular Mean Pressure Gradient (mPG)14.1 mmHgStandard Deviation 4.3
CEPME GroupTransvalvular Mean Pressure Gradient (mPG)13.9 mmHgStandard Deviation 5.1
Comparison: The null hypothesis was that the AvalusTM was inferior to the CEPME based on the AVMPG at 1-year echocardiographic follow-up, with a non-inferiority margin of 3mmHg. The result for the primary endpoint was presented with 97.5% one-sided confidence interval for mean difference between groups. The non-inferiority test was performed using a t-test which compared mean difference between groups with the non-inferiority margin under the one-sided significance level of 0.025.p-value: 0.0004t-test, 1 sided
