Tricuspid stenosis (TS) is the least common valvular disease. TS is rarely an isolated disease, it is mostly associated with mitral valve and/or aortic valve abnormalities. Approximately 8% of patients with rheumatic heart disease develop isolated TS, while up to 50% develop tricuspid regurgitation and TS. The prevalence of TS is lower in developed countries compared to developing countries due to the low prevalence of rheumatic heart disease, which is the most common cause of TS.
Epidemiology and Demographics
- United States data shows that tricuspid stenosis is rare, occurring in less than 1% of the population.
- While found in approximately 15% of patients with rheumatic heart disease at autopsy, it is estimated to be clinically significant in only 5% of these patients.
- The incidence of the congenital form of the disease is less than 1%.
- Tricuspid stenosis is found in approximately 3% of the international population.
- Tricuspid stenosis is more prevalent in areas with a high incidence of rheumatic fever.
- Tricuspid stenosis can present as a congenital lesion or later in life when it is due to some other condition.
- The congenital form accounts for approximately 0.3% of all congenital heart disease cases.
- The frequency of tricuspid stenosis in the older population, due to secondary causes, ranges from 0.3-3.2%
- Tricuspid stenosis is observed more commonly in women than in men, similar to mitral stenosis of rheumatic origin.
- The congenital form of the disease has a slightly higher male predominance.
- No racial predisposition is apparent.
