Monitoring the long-term performance of several bioprosthetic aortic valves

Overall, according to the authors, the Perimount aortic valve (Edwards Lifesciences) provided the best long-term performance with a 10-year reoperation rate of 3%. The 10-year reoperation rates for the other valves included in the study were 3.5% for Mosaic/Hancock valves (Medtronic), 3.7% for Biocor/Epic valves (Abbott), 9.2% for Mitroflow/Crown valves (LivaNova) and 9.3% for the Soprano valve (LivaNova).

No 10-year data on the Trifecta (Abbott) valve was available, but its five-year reoperation rate of 2.2% put it in the middle of the pack.

Additionally, the authors found that the Perimount valve had the lowest all-cause mortality after 10 years (44%). The highest all-cause mortality rate after 10 years, meanwhile, was 70% observed in Mitroflow/Crown valves.

Additionally, looking specifically at hospitalizations for heart failure, the Perimount valve had the lowest rate after 10 years (14%) and the Mitroflow/Crown valves had the highest rate (25.9%).

“These results support the extensive use of the Perimount valve and suggest the need for increased clinical vigilance in patients who receive either a Soprano valve or a Mitroflow/Crown valve,” the authors wrote.
