Background

Thelong-term durability of transcatheter heart valves (THVs) is crucial for thelifelong management of patients with valvular aortic stenosis and provides animportant reference for developing new valves. This study aimed to report thelong-term clinical outcomes of three early-generation THVs.

Methods

Atotal of 235 patients who underwent transcatheter aortic valve replacement(TAVR) were included. The THVs analyzed were the self-expanding CoreValve(Medtronic Inc.) bioprosthesis (n = 111), the mechanically expandable Lotus(Boston Scientific Inc.) bioprosthesis (n = 16), and the balloon-expandableSapien XT (Edwards Lifesciences Inc.) bioprosthesis (n = 108). Major adversecardiac and cerebral events (MACCE) were defined as all-cause mortality,stroke, or myocardial infarction. Bioprosthetic valve dysfunction, includingstructural valve deterioration (SVD) and bioprosthetic valve failure (BVF), wasclassified according to Valve Academic Research Consortium-3 criteria.

Results

Baselinecharacteristics were comparable among the CoreValve, Lotus, and Sapien XTgroups: age (80.17¡¾7.72 years, 77.13¡¾8.69 years, and 77.93¡¾8.62 years,respectively; p = 0.087), male gender distribution (CoreValve: 50.4%, Lotus:6.1%, and Sapien XT: 43.5%; p = 0.618), and Society of Thoracic Surgeons scores(10.73¡¾9.37, 7.24¡¾4.84, and 10.9¡¾9.37, respectively; p = 0.319). After a medianfollow-up of 4.64 years, the risk of MACCE was 63.1% for CoreValve, 50.0% forLotus, and 61.1% for Sapien XT (p = 0.604). The cumulative incidences of valvethrombosis and endocarditis were low and similar among all three bioprostheses.Severe SVD was observed in 9.9% of CoreValve, 6.0% of Lotus, and 6.5% of SapienXT cases (p = 0.56). However, BVF requiring reintervention was noted in 0.9%(1/111) for CoreValve, 12.5% (2/16) for Lotus, and 1.9% (2/108) for Sapien XT(p = 0.011).

Conclusion

Early-generationTHVs show comparable long-term clinical outcomes in elderly high-risk patients;however, intra-annular valve designs with a higher amount of metal structuremay adversely affect valve durability.
