Major arteries of the body
| Valve | Site of auscultation | Clinical significance |
|---|---|---|
| Tricuspid | 🔷 4th left parasternal intercostal space | 🔷 Most commonly affected valve in infective endocarditis in individuals who inject drugs intravenously (🆚) |
| Pulmonary | 🔷 2nd left parasternal intercostal space | 🔷 Pulmonary valve stenosis is most commonly congenital |
| 🔷 Rarely, it occurs secondary to another condition (e.g., carcinoid heart disease). | ||
| Mitral | 🔷 5th left intercostal space in the midclavicular line | 🔷 Most commonly affected valve in infective endocarditis overall (🆚) |
| 🔷 Mitral stenosis is the most common manifestation of rheumatic heart disease. | ||
| Aortic | 🔷 2nd right parasternal intercostal space | 🔷 Bicuspid aortic valve is common in individuals with Turner syndrome. |
| 🔷 Aortic valve sclerosis occurs due to age-related calcification and fibrosis of the aortic leaflets. |
