Trifecta Versus Perimount Magna Ease Aortic Valve Prostheses
The authors comducted a comparative analysis of the Trifecta and Perimount Magna Ease bioprosthetic valves, using data from a national Finnish database between 2008 and 2017.
They included 2216 patients, with a mean follow-up 3.8±2.1 years. 851 patients received the Trifecta valve and 1365 received the Perimount Magna Ease bioprosthesis. The rates of late mortality and prosthetic valve endocarditis were comparable in the study cohorts. At 7-year, the Trifecta cohort had significantly higher risk of repeat aortic valve replacement for structural valve failure (3.3% vs. 0%), repeat aortic valve replacement for any cause (3.6% vs. 0.4%) and repeat aortic valve replacement and/or prosthetic valve endocarditis (4.1% vs. 0.9%) compared to the Perimount Magna Ease cohort.
Among 772 propensity score matched pairs, at 7-year, the Trifecta cohort had a higher risk of repeat aortic valve replacement for structural valve failure (5.7% vs. 0%).
The authors report that the Trifecta aortic bioprosthesis is associated with a higher occurrence of repeat aortic valve replacement for structural valve failure compared to the Perimount Magna Ease bioprosthesis.
