1

Displacement (ballooning) of the mitral valve leaflets into the left atrium during ventricular systole

Mitral Valve Prolapse

2

Typically asymptomatic

Mitral Valve Prolapse

3

Woman usually affected more than men

Mitral Valve Prolapse

4

Midsystolic click or systolic murmur

Mitral Valve Prolapse

5

palpitations; rhythm abnormalities; dizziness; fatigue; dyspnea; chest pain; or depression and anxiety

Mitral Valve Prolapse

6

Predominant cause is age-related calcium deposits on the aortic cusps

Aortic Stenosis

7

Left ventricle hypertrophy may result in ischemia and left-sided heart failure

Aortic Stenosis

8

Crescendo-decrescendo murmur during ventricular systole with prominent S4; syncope; fatigue; angina

Aortic Stenosis

9

Results in obstruction of aortic outflow from the left ventricle into the aorta during systole

Aortic Stenosis

10

Incompetent aortic valve allows blood to leak back from the aorta into the left ventricle during diastole

Aortic Regurgitation

11

Causes: abnormal aortic valve or aortic root dilation

Aortic Regurgitation

12

Leads to left ventricle hypertrophy and dilation with eventual left-sided heart failure

Aortic Regurgitation

13

High-pitched blowing murmur during ventricular diastole;

Aortic Regurgitation

14

high systolic blood pressure; diastolic blood pressure usually low; palpitations

Aortic Regurgitation

15

Acute inflammatory disease that follows infection with group A β-hemolytic streptococci

Rheumatic heart disease

16

Damage is due to immune attack on the individual’s own tissues

Rheumatic heart disease

17

Antibodies against the streptococcal antigens damage connective tissue in joints, heart, skin

Rheumatic heart disease

18

Occurs mainly in children

Rheumatic heart disease

19

Fever; sore throat; joint inflammation; erythema marginatum, involuntary movements (Sydenham chorea); and a distinctive truncal rash

Rheumatic heart disease

20

Invasion and colonization of endocardial structures by microorganisms with resulting inflammation—vegetations

Infective endocarditis

21

What are the most common bacteria in infective endocarditis

Staph and Strepto

22

Prognosis poor
Intravenous drug users susceptible

Acute infective endocarditis

23

Predisposing risk factors typically present

Subacute infective endocarditis

24

inflammatory disorder of the heart muscle characterized by necrosis and degeneration of myocytes

Myocarditis

25

Clinical course: acute and stormy, with recovery or death from cardiac failure occurring weeks to months after the onset of symptoms

Myocarditis

26

may be genetic or acquired and is noninflammatory

Cardiomyopathy

27

Evolve more insidiously over years, with few symptoms until the heart slips into failure

Cardiomyopathy

28

Characterized by inflammation, leukocyte infiltration, necrosis of cardiac muscle cells

Myocarditis

29

Causes include microbial agents, immune-mediated diseases, physical agents

Myocarditis

30

Viral etiology most common

Myocarditis
