Abstract:
Abstract OBJECTIVES Despite promising short- and mid-term results for durability of the Trifecta valve, contradictory reports of early structural valve deterioration (SVD) do exist. We investigated the incidence of SVD after surgical aortic valve replacement (SAVR) with the Trifecta in our single-centre experience. METHODS Data of 347 consecutive patients (mean age 71.6 ± 9.5 years, 63.4% male) undergoing SAVR with the Trifecta between 2011 and 2017 were analysed. Clinical and echocardiographic reports were obtained with a median follow-up of 41 months (1114 patient years). RESULTS Isolated SA

The Carpentier-Edwards supra-annular porcine bioprosthesis (second generation prosthesis) was implanted in 2438 patients in 2482 operations between 1982 and 1992. The mean age of the population was 64 years with a range from 21 years to 89 years. There were 1334 aortic and 934 mitral valve replacements. The population was divided into five groups: 21 to 40 years (n = 132); 41 to 50 years (n = 189); 51 to 60 years (n = 454); 61 to 70 years (n = 849); and over 70 years (n = 858).

Previous research has suggested that the structural deterioration in porcine bioprosthetic heart valves (BHV) may be correlated with the regions of high tensile and bending stresses acting on the leaflets during opening and closing[1, 2]. Stress concentrations within the cusp can either directly accelerate tissue structural fatigue damage, or initiate calcification by causing structural disintegration, enabling multiple pathways of calcification that can lead to valve failure[3,4].

Valvular heart disease results in approximately 275,000 valve replacement procedures performed annually worldwide. Structural deterioration, calcification, tissue overgrowth, and thromboembolism frequently lead to abnormal tissue stiffness levels that contribute to the failure of native heart valves. While many treatment alternatives exist, understanding the factors that regulate the activity of heart valve cells is critical for circumventing pathological heart valve fibrosis and engineering improved biologically active heart valve replacements.
