• Studies conducted in developed nations have shown that increase in life expectancy has brought with it a rise in the incidence and treatment of degenerative aortic and mitral heart valve diseases. Current standards recommend valve replacement among even some asymptomatic patients. In this research, we examine the epidemiology of valvular heart disease and rate of valve replacement in Taiwan, where life expectancy now stands at 80.69 years. Patients were enrolled based on claims from a widely used national database and categorized into cohorts defined by type of valve disease and, further, by valve replacements and type of valve (mechanical, porcine, or bovine). Data, including disease type, age, and gender, were analyzed to determine annual and cumulative incidence rates and prosthetic usage from 2000 to 2017. Results showed that across the cohorts, the cumulative incidence rate in 2017 was 3.59%, and in the aortic valve cohort, the percentage of surgical valve replacement for those ≥60 years was 6.99%. Compared with other developed nations, this demonstrates that incidence rates are slightly higher, yet surgical replacements are less than half that of other developed nations. This under-treatment of patients with valvular heart disease presents an important public health challenge in Taiwan.
