Popis: Background ESC guidelines recommend annual echocardiographic evaluation following biological surgical aortic valve replacement (SAVR), and 5 years following mechanical SAVR. Conversely, increased life expectancy result in increasing demand on health care resources. Purpose To assess aortic reintervention rates at 1-year, 3-year and 5-year following biological and mechanical SAVR in relation to estimated echocardiographic controls. Methods From the nationwide Danish Register of Surgical Procedures, we identified all patients ≥40 years with isolated biological or mechanical SAVR +/− concomitant coronary artery bypass graft surgery (CABG) during 2000–2016. In 90-day reintervention-free survivors we assessed aortic valve reintervention rates at 1-year, 3-years and 5-years until December 31st, 2017. We further assessed cumulative risk of reintervention by age ( Results The population of 90-day reintervention-free survivors included 10,526 patients with biological SAVR (CABG 39.7%) and 3,677 patients with mechanical SAVR (CABG 23.8%). Reintervention rates at 1-year, 3-years and 5-years were comparable across type of SAVR, and generally low (Figure). Accounting for the competing risk of death, reintervention rates at 5-years were 1.4% (95% CI 1.1–1.6) for biological SAVR and 1.5% (95% CI 1.1–1.9) for mechanical SAVR, respectively. In age-stratified competing risk analyses, we observed the highest rates in patients aged 40–59 years (4% [95% CI 1.8–6] at 5 years for biological SAVR, and 2% [95% CI 1.3–3] for mechanical SAVR). Following biological SAVR, annual echocardiographic controls would yield a total of 34,516 scans in our population in the first 5 years following surgery. This contrasts to a total of 66 reinterventions following biological SAVR in our population between years 1–5 of which the majority was preceded by a hospital admission with a primary diagnosis of endocarditis within the last 90 days prior to the reintervention; which are unlikely to have been diagnosed at the annual assessment scan. Conclusion(s) In this nationwide study, reintervention rates following biological or mechanical SAVR were very low within the first five years after surgery suggesting a discrepancy between ESC recommendations on echocardiographic controls following SAVR, the benefit for patients, and the associated resource burden on the health care system.
