What is Heart Valve Disease?
Valvular heart disease is characterized by narrowing or leaking of any of those or more valve.
In heart there are four values. Such as-
- Aortic valve
- Mitral valve
- Pulmonary valve
- Tricuspid valve.
Types of Valvular Heart Disease:
There are two types of heart valve disease. Those are in the following with details.
Valvular Stenosis results from a narrowing of the valve orifice that is usually caused by a thickening and increased rigidity of the valve leaflets. The narrowed opening may make the heart work very hard to pump blood through it. All four valves can be stenosis such as- Aortic stenosis, Mitral Stenosis, Tricuspid Stenosis, Pulmonic Stenosis.
Valvular Insufficiency results from the valve leaflets not completely sealing when the valve is closed so that a backward flow (Regurgitation) of blood occurs into the heart. Depending on which valve is affected, the condition is called tricuspid regurgitation, pulmonary regurgitation, mitral regurgitation or aortic regurgitation.
Causes of Valvular Heart Disease or Valvular Heart Disease Causes:
There are different causes for heart valve disease. Those are in the following-
For Valvular Regurgitation:
- Acute rheumatic Carditis,
- Valve ring dilatation (eg-dilated cardiomyopathy),
- Traumatic valve rupture,
- Senile degeneration,
- Damage to chordae and papillary muscle,
- Syphilitic aortitis,
- Mitral valve prolapsed,
- Systemic lupus erythematosus,
- Aortic aneurysm.
For Valvular Stenosis:
- Rheumatic Carditis,
- Senile degeneration,
- Carcinoid tumors.
Sign and Symptoms of Valvular Heart Disease or Valvular Heart Disease Symptoms:
There are several sign and symptoms for heart valve disease. Those are in the following-
- Shortness of breath,
- Weakness or dizziness,
- Wheezing and heavy coughing,
- Physical exertion,
- Palpitations mild chest pain,
- Rapid weight gain,
- Swelling of the ankles, feet or abdomen.
Diagnosis for Valvular Heart Disease:
The main diagnosis ways for heart valve disease are in the following:
- Stress testing,
- Cardiac catheterization (Angiogram),
- Radionuclide scans.
Treatment for Valvular Heart Disease or Valvular Heart Disease Treatment:
Different treatment formulas of heart valve disease are in the below-
1. Lifestyle Modifications,
- Antibiotic (To prevent bacterial endocarditis).
- Diuretics (remove extra fluid) – furosemide.
- Antiarrhythmic (control of heart’s rhythm) -Lidocaine, Amiodarone.
- ACE Inhibitors (Reduce after load by forward direction rather than backwards through a leaky valve -Captopril, Enalapril.
- Beta Blockers (Slow heart rate and improve cardiac output) – Metoprolol, Bisoprolol.
- Anticoagulants (prevent blood clot) – Heparin.
3. Surgery and procedures:
- Balloon dilatation
- Minimally – Invasive Atrial Septal defect closure.
- Minimally – Invasive valve repair and replacement.
- Minimally –Invasive Aortic valve replacement.
Prevention for Valvular Heart Disease:
There are different ways for the prevention of for heart valve disease. Those are in the below:
- Stop smoking.
- Consume no more than two alcoholic beverages a day.
- Eat a healthy, balanced diet (low salt and fat).
- Regular exercise and control weight.
- Maintain careful control of blood sugar.
Nursing Intervention for Valvular Heart Disease or Valvular Heart Disease Guidelines:
Nursing interventions for heart valve disease are in the below-
- Assess mental status (Restlessness, severe anxiety and confusion).
- Check vital signs (heart rate and blood pressure).
- Assess heart sounds, noting gallops, S3, S4.
- Assess manually peripheral pulses (with weak rate, rhythm indicated low cardiac output).
- Assess lung sounds and determine any occurrence of Paroxysmal Nocturnal Dyspnea (PND) or orthopnea.
- Monitor central venous, right arterial pressure [RAP], pulmonary arterial pressure(PAP)
- Routinely Assess skin colour and temperature (Cold, clammy skin is secondary to compensatory increase in sympathetic nervous system stimulation and low cardiac output and desaturation).
- Carefully maintain intake output and daily check weight.
- Administer medication as prescribed, noting response and watching for side effects and toxicity.
- Administer stool softeners as needed(s training for a bowel movement further impairs cardiac output).
- Explain drug regimen, purpose, dose, and side effects.
- Maintain adequate ventilation and perfusion (Place patient in semi- to high-Fowler’s position or supine position).
- Administer O2 as ordered.
- Assess response to increased activity and help patient in daily activities.
- Maintain physical and emotional rest (restrict activity and provide quiet and relaxed environment).
- Monitor sleep patterns; administer sedative.
- If invasive adjunct therapies are indicated (e.g., intra-aortic balloon pump, pacemaker), maintain within prescribed protocol and prepare patient.
- Explain diet restrictions (fluid, sodium).
