Evaluating Health of Emerging Economies Through the Eyes of Heart Valve Disease in the Transcatheter Era

China and India are the 2 fastest growing major world economies. However, they suffer from great differences in health policies, demographics, and rates of population growth. Whereas China has seen a steep decline in rheumatic heart disease (RHD) and a rise in life expectancy, India continues to suffer from a significant burden of RHD due to insufficient distribution of economic prosperity to health care, denser population, and ineffective application of World Health Organization RHD prevention guidelines. As China faces the burden of the world's largest geriatric population, focus has shifted to calcific aortic stenosis for which it prepares by expansions in the field of transcatheter aortic valve replacement. Conversely, India has a younger population and a lower average life expectancy. Therefore, focus in India has still not shifted to calcific aortic stenosis as a major cause of morbidity and mortality as RHD continues to constitute the bulk of valvular heart disease.
