Adaptive responses preserve cardiac function and delay the diagnosis of chronic valvular disease but contribute to eventual cardiac dysfunction. Compared with the general population, patients with clinically evident valvular heart disease have a 2.5-fold higher death rate and a 3-fold increased rate of stroke.1
