Study Notes
Valvular Heart Disease Overview
- Valvular heart disease impacts the proper functioning of heart valves, affecting blood flow.
- Two main issues: stenosis (thickening of valve tissue) and insufficiency (inability of valve to close completely).
- Possible intervention includes valve replacement.
Heart Valves
- Four main valves:
- Tricuspid
- Pulmonary semilunar
- Mitral (bicuspid)
- Aortic semilunar
- Normal function involves passive opening and closing, maintaining unidirectional blood flow.
Normal Blood Flow Pathway
- Blood enters the right atrium via inferior and superior vena cava.
- Flows through the tricuspid valve to the right ventricle, then through the pulmonary semilunar valve to the pulmonary artery.
- Oxygenated blood returns to the left atrium via pulmonary veins, moves through the mitral valve to the left ventricle, and exits through the aorta to the body.
Types of Valvular Heart Disease
- Occurs due to valve damage, leading to improper opening and closing.
- Two primary dysfunctions:
- Stenosis: narrowing of the valve.
- Regurgitation: valve fails to close, allowing backward blood flow.
Etiology and Pathophysiology
- Congenital disorders can affect all age groups.
- History of rheumatic fever is a key risk factor, with symptoms potentially manifesting 10-40 years post-infection.
- Streptococcal infections may remain dormant in the mitral or aortic valves.
Common Valvular Heart Disorders
- Mitral stenosis
- Mitral insufficiency
- Mitral prolapse
- Aortic stenosis
- Aortic insufficiency
- Tricuspid stenosis
- Pulmonary stenosis
Clinical Manifestations
- Symptoms vary based on specific valvular disease.
- Common signs include decreased cardiac output and severity of heart failure.
- Disease staging guides treatment recommendations.
Assessment Indicators
Subjective
- Past history of rheumatic fever.
- Symptoms such as fatigue, shortness of breath, chest pain, lightheadedness, and dyspnea (exertional and nocturnal).
Objective
- Heart murmurs identified through auscultation.
- Adventitious breath sounds and edema (pitting or non-pitting) may be present.
Diagnostic Tests
- Essential tests include chest radiograph, echocardiogram, and cardiac catheterization to evaluate heart function and structure.
Medical Management Strategies
- Implement activity limitations to manage symptoms.
- Sodium restrictions may be advised for patients to reduce fluid retention and manage heart workload.
