BackgroundLong‐term data on durability of currently available transcatheter heart valves are sparse. We sought to assess the incidence of long‐term (8‐year) structural valve dysfunction and bioprosthetic valve failure in a cohort of patients with transcatheter aortic valve replacement (TAVR) who reached at least 5‐year follow‐up.Methods and ResultsConsecutive patients with at least 5‐year follow‐up available undergoing TAVR from June 4, 2007 to March 30, 2012 were included. Structural valve dysfunction and bioprosthetic valve failure were defined according to newly standardized European Association of Percutaneous Cardiovascular Interventions/European Society of Cardiology/European Association for Cardio‐Thoracic Surgery criteria and reported as cumulative incidence function to account for the competing risk of death. A total of 288 consecutive patients with a mean age of 80.7±5.3 years and with a mean Society of Thoracic Surgery mortality score of 8.1±5.1% were analyzed. Survival rate at 8 years was 29.8%. Mean pressure gradients decreased from 53.3±15.9 mm Hg (pre‐TAVR) to 10.5±4.5 mm Hg (in‐hospital post‐TAVR) (P<0.001). There was a small, not significant, increase in the transaortic gradient throughout follow‐up. Bioprosthetic valve failure was observed in a total of 11 patients (8‐year cumulative incidence function: 4.51%; 95% confidence interval, 1.95%–8.76%). Severe and moderate structural valve dysfunctions were reported in 7 patients (8‐year cumulative incidence function: 2.39%; 95% confidence interval, 0.77%–5.71%) and 13 patients (8‐year cumulative incidence function: 5.87%; 95% confidence interval, 3.06%–9.96%), respectively. Aortic valve reintervention (redo TAVR) was successfully performed in 2 patients (0.7%) presenting with symptomatic severe restenosis and intraprosthetic regurgitation subsequent to endocarditis.ConclusionsIn an aged population of patients with symptomatic severe aortic stenosis treated with first‐generation bioprostheses, TAVR was associated with a survival rate of 30% but low rates of bioprosthetic valve failure and structural valve dysfunction at 8 years.

“…86 In rare cases, early CEP valve structural failures have also been observed. 87 These failures are thought to be largely due to heterogeneity in the structure and properties of the GLBP leaflets, which leads to leaflet tearing and/or prolapse due to elongation of one or more of the leaflets. 9,87,88 The main limitation of in vivo studies is that they are not well controlled due to patient variability, which makes it difficult to compare explanted valves and identify the mechanisms of fatigue.…”

Mechanical fatigue damage is a critical issue for soft tissues and tissue-derived materials, particularly for musculoskeletal and cardiovascular applications; yet, our understanding of the fatigue damage process is incomplete. Soft tissue fatigue experiments are often difficult and time-consuming to perform, which has hindered progress in this area. However, the recent development of soft-tissue fatigue-damage constitutive models has enabled simulation-based fatigue analyses of tissues under various conditions. Computational simulations facilitate highly controlled and quantitative analyses to study the distinct effects of various loading conditions and design features on tissue durability; thus, they are advantageous over complex fatigue experiments. Although significant work to calibrate the constitutive models from fatigue experiments and to validate predictability remains, further development in these areas will add to our knowledge of soft-tissue fatigue damage and will facilitate the design of durable treatments and devices. In this review, the experimental, modeling, and simulation efforts to study collagenous tissue fatigue damage are summarized and critically assessed.
