Overview
The prevalence of mild pulmonary regurgitation (PR) is present in 40% to 78% of patients with normal anatomy of the pulmonary valve. In patients born with congenital heart disease, 20% of patients have associated abnormalities of the pulmonary valve or the right ventricular outlet obstruction. The incidence and prevalence of PR increase with age. 24% of deaths due to valvular heart disease are attributed to tricuspid valve and pulmonic valve abnormalities combined. There is one study supporting the increased prevalence of PR among women. In developing countries Pulmonary hypertension (PAH) is primarily due to rheumatic heart disease (RHD) which is rare in developed countries. PAH is a major cause of secondary PR.
Epidemiology and Demographics
Prevalence
- The prevalence of valvular heart disease in U.S. population is estimated to be 2.5%. About 13% of U.S population born before 1943 have valvular heart disease.[1]
- The prevalence of mild PR is present in 40% to 78% of patients with normal anatomy of the pulmonary valve.[2][3][4][5]
- In 1987, the prevalence of PR in patients with structurally normal hearts was estimated to be 5% in Boston area population, USA.[2]
- In 1990, the prevalence of PR in normal patients (21 - 82 years) was estimated to be 31%.[5]
- In 1992, the prevalence of PR in children (birth- 14 years) with structurally normal hearts was estimated to be 21.9% in Jerusalem, Israel population. Pulmonic regurgitation was the most common of all valvular regurgitations detected among children.[6]
Incidence
- In patients born with congenital heart disease, 20% of patients have associated abnormalities of the pulmonary valve or the right ventricular outlet obstruction.[2]
Case-fatality rate/Mortality rate
- In 2017, CDC reported that 24% of deaths due to valvular heart disease were attributed to tricuspid valve and pulmonic valve abnormalities combined.[1]
Age
- The prevalence of pulmonary regurgitation (PR) is estimated to have two demographic peaks. The first peak is among young patients with repaired congenital pulmonary stenosis. The second peak is among patients with pulmonary arterial hypertension (PAH).[7] The multitude of causes makes the determination of exact prevalence of PR difficult.[8]
- In the U.S population, the prevalence of valvular heart disease is higher in older adults.[1]
- In 1989, a meta‐analysis reported that 29% of the patients with isolated congenital PR develop symptoms within 40 years. The risk of development of symptoms demonstrated an increase with age, particularly after 40 years.[9]
- In 1990, the incidence of mild degree valvular regurgitation in normal subjects was estimated to increase with age.[5]
- In 2017, the incidence of PR in Tibetans (one of the highest cities in the world) was found to increase with age.[10]
Race
- There is no racial or ethnic predilection for pulmonary regurgitation.
Gender
- In 2017, Pulmonic regurgitation (PR) was found to be more prevalent in Tibetan women.[10]
Developed Countries
- In developed countries such as the United States, Pulmonary hypertension (PAH) is primarily due to left heart disease. Other conditions that cause PAH include sickle cell disease; pulmonary embolus, and chronic obstructive pulmonary disease (COPD).[11] PAH is a major cause of secondary PR.
- Rheumatic heart disease (RHD) is not a common cause of PAH or PR in developed countries. Due to the early detection and development of treatment strategies RHD is rare in developed countries.[12][13]
Developing Countries
- In developing countries Pulmonary hypertension (PAH) is primarily due to rheumatic heart disease (RHD), schistosomiasis, congenital heart disease, hemolytic diseases. PAH is a major cause of secondary PR. The burden of PAH is greater in developing than developed countries.[12][14]
