Valvular Heart Disease
| Question | Answer |
|---|---|
| What is a common cause of Mitral stenosis | Rheumatic Heart Disease |
| What is a common cause of mitral regurgitation | Mitral Valve Prolapse |
| What is a common cause of aortic stenosis | Congenital bicuspid aortic valve/acquired valvular cacification |
| what is a comon cause of aortic regurgitation | congenital bicuspid aortic valve/aortic dilation |
| what are the clinical components of rheumatic fever | Fever, Migratory polyarthritis of the large joints, subcutaneous nodules, erythema marginatum, Sydenham's chorea, and carditis |
| What pathological finding is pathognomonic for carditis | aschoff bodies |
| what is the most common valve affected by rheumatic fever | mitral valve |
| what are the secondary cardiac effects of rheumatic fever | congestive heart failure and risk for endocarditis |
| what is the classic murmur of mitral valve prolapse | mid-systolic click (snapping of cusp and chordae) |
| What is congenital stenosis | when the valvular opening is too small, structurally the valves may be normal, tri, bi, or unicuspid |
| what is pathognomonic for endocardial infection | infective vegetations |
| when you see huge vegetations, valve perforation, myocardial extension with ring abscess formation is the endocarditis most likely acute or subacute | acute |
| what bacteria is responsible for 50-60% of cases of endocarditis | strep viridans |
| What group do you have to worry most about right sided endocarditis | IV drug abusers |
| What is Libman-Sacks Endocarditis associated with? | SLE (valves affected in up to 50% of lupus patients) |
| what is carcinoid heart disease | plaque like pearly white fibrous thickening of the RV endocardium |
| what are symptoms of carcinoid syndrome | N/V, diarrhea, Flushing |
| what valves are most affected by Carcinoid | tricuspid and pulmonary (stenosis not regurge) |
| what valve is not typically affected by rheumatic fever | pulmonary |
| does rheumatic fever have the potential to cause stenosis or regurge of the mitral, aortic and Tricuspid valves | both in all |
| What valves does SLE usually affect | Mitral (stenosis and regurge) and Aortic (regurge only) |
| Is endocarditis more likely to cause regurge or stenosis of the aortic and mitral valves | regurge |
