Valvular Disease: What affects valves?
|
Rheumatic heart disease
calcium buildup (elderly) What changes shape of valves? Damage to the structures in the heart MI (young/elderly) |
|
|
Valvular Disease: What causes Valve Disease?
|
Infection
congenital defect Calcium buildup Rheumatic fever Endocarditis Pulmonary edema Left sided heart failure |
|
|
Valvular Disease: LEFT-SIDE VALVES
|
Mitral Valve (Bicuspid Valve)
Valve between left atria & left ventricle. Opens down into ventricle. Suspended by chordae tendinae & papillary muscle Aortic Valve Valve between left atria & aorta. Opens up into aorta |
|
|
Valvular Disease: RIGHT-SIDE VALVES
|
Tricuspid Valve
Valve between right atria & right ventricle. Opens down into ventricle. Suspended by chordae tendinae & papillary muscle. Pulmonary Valve Valve between right atria & pulmonary artery. Opens up into pulmonary valve |
|
|
Valvular Disease: Blood flow
|
Left side:
Lung - Left aritum/ventricle -aorta-body Right side: Vena cava - Rt. atrium/ventricle - pulmonary artery - lung |
|
|
Valvular Disease: stenosis-what is the blood flow?
|
Mitral valve, if narrow, causes the valve not to open properly & to obstruct blood flow between left atrium & ventricle. Blood flow reduced.
Aortic stenosis, if narrow, causes the valve to not open properly & to obstruct blood flow between ventricle and aorta. |
|
|
Valvular Disease: stenosis-Causes
|
genetic heart defect
Rheumatic fever |
|
|
Valvular Disease: stenosis-Risk Factors
|
calcium buildup on valve
|
|
|
Valvular Disease: stenosis-If backs up into left atrium?
|
Mitral Valve Regurgitation
blood backs up because valve not close properly & leaks up into left atrium from left ventricle during contraction (systole) because valve not able to close completely.Termed “Chronic” if long-term disorder. |
|
|
Valvular Disease: If backs up into left atrium? Cause
|
Rheumatic fever
Due to atherosclerosis & hypertension left-ventricle enlargement congenital defects endocarditis connective tissue disorders cardiac tumors syphilis (rare) |
|
|
Valvular Disease: If backs up into left atrium? Signs & symptoms
|
Atrial fibrillation
fatigue, exhaustion, lightheadedness cough, shortness of breath dyspnea orthopnea |
|
|
Valvular Disease: If backs up into left ventricle?
|
Aortic Valve Regurgitation
Valve doesn't close properly & blood can leak backward through it. This means the left ventricle must pump more blood than normal, and will gradually get bigger because of the extra workload (chronic). Leaking of aortic valve- blood flows in the reverse direction during ventricular diastole, from the aorta into the left ventricle. |
|
|
Valvular Disease: If backs up into left ventricle?
|
Infection or congenital abnormalities
Deterioration of the valve with age Endocarditis Rheumatic fever Pulmonary edema Left sided heart failure |
|
|
Valvular Disease: If backs up into left ventricle? Causes
|
Infection or congenital abnormalities
Deterioration of the valve with age Endocarditis Rheumatic fever Pulmonary edema Left sided heart failure |
|
|
Valvular Disease: If backs up into left ventricle? Signs & Symptoms
|
Fatigue
Shortness of breath Edema Heart arrhythmias Angina pectoris (chest pain) |
