In heart valve disease, one or more of the valves in your heart doesn't work properly.
Your heart has four valves that keep blood flowing in the correct direction. In some cases, one or more of the valves don't open or close properly. This can cause the blood flow through your heart to your body to be disrupted.
Your heart valve disease treatment depends on the heart valve affected and the type and severity of the valve disease. Sometimes heart valve disease requires surgery to repair or replace the heart valve.Your heart has four valves that keep blood flowing in the correct direction. These valves include the mitral valve, tricuspid valve, pulmonary valve and aortic valve. Each valve has flaps (leaflets or cusps) that open and close once during each heartbeat. Sometimes, the valves don't open or close properly, disrupting the blood flow through your heart to your body.
Heart valve disease may be present at birth (congenital). It can also occur in adults due to many causes and conditions, such as infections and other heart conditions.
Heart valve problems may include:
Regurgitation. In this condition, the valve flaps don't close properly, causing blood to leak backward in your heart. This commonly occurs due to valve flaps bulging back, a condition called prolapse.
Stenosis. In valve stenosis, the valve flaps become thick or stiff, and they may fuse together. This results in a narrowed valve opening and reduced blood flow through the valve.
Atresia. In this condition, the valve isn't formed, and a solid sheet of tissue blocks the blood flow between the heart chambers.Several factors can increase your risk of heart valve disease, including:
Older age
History of certain infections that can affect the heart
History of certain forms of heart disease or heart attack
High blood pressure, high cholesterol, diabetes and other heart disease risk factors
Heart conditions present at birth (congenital heart disease)Heart valve disease can cause many complications, including:
Heart failure
Stroke
Blood clots
Heart rhythm abnormalities

Pediatric nurses play a vital role in the health and well-being of children. Their responsibilities are wide-ranging, and their objectives can be categorized into several key areas:
1. Direct Patient Care:
Objective: Provide comprehensive and compassionate care to infants, children, and adolescents in various healthcare settings (hospitals, clinics, etc.).
This includes tasks like:
Monitoring vital signs and physical condition.
Administering medications and treatments.
Performing procedures as directed by doctors.
Assisting with daily living activities (bathing, feeding).
Providing emotional support and pain management.
2. Health Promotion and Education:
Objective: Promote healthy behaviors and educate children, families, and communities about preventive healthcare.
This includes tasks like:
Administering vaccinations.
Providing education on nutrition, hygiene, and development.
Offering breastfeeding and childbirth support.
Counseling families on safety and injury prevention.
3. Collaboration and Advocacy:
Objective: Collaborate effectively with doctors, social workers, therapists, and other healthcare professionals to ensure coordinated care for children.
Objective: Advocate for the rights and best interests of their patients, especially when children cannot speak for themselves.
This includes tasks like:
Communicating effectively with healthcare teams.
Identifying and addressing potential risks to child welfare.
Educating families about their child's condition and treatment options.
4. Professional Development and Research:
Objective: Stay up-to-date on the latest advancements in pediatric healthcare through continuing education and research.
Objective: Contribute to improving the quality of care for children by participating in research initiatives.
This includes tasks like:
Attending workshops and conferences on pediatric nursing.
Participating in clinical trials related to child health.
Implementing evidence-based practices into their daily routines.
By fulfilling these objectives, pediatric nurses play a crucial role in ensuring the optimal health and well-being of children throughout all stages of their development.
2. NORMAL HEART
Heart is a muscular structure which is associated with pumping of
blood. It has four chambers – left atrium, left ventricle, right atrium and
right ventricle. Left side of the heart is associated with pumping
oxygenated blood to whole body, while right side of the heart is
associated with pumping deoxygenated blood to the lungs.
3. VALVES
• Valves are structures that restricts back flow of fluids, allows
unidirectional movement of fluid (mainly blood) in human body.
• In human heart, there are 4 valves
• Mitral
• Tricuspid
• Aortic
• Pulmonary
4. VALVULAR APPARATUS
• It is made up of the components which are constituted in a valve, and
they are-
• Fibrous ring
• Leaflets
• Chorda tendinea
• Papillary muscles
6. MITRAL VALVE
• Also known as the bicuspid valve/left atrioventricular valve.
• Situated between the left atrium and left ventricle.
• It is made up of two flaps of tissue which opens during left ventricular
diastole and closes during isovolumetric systole of left ventricle.
• Contains 2 leaflets-
• Anterior
• Posterior
7.
8. TRICUSPID VALVE
• Also known as right atrioventricular valve
• Situated between right atrium and right ventricle. Opens during
ventricular diastole and closes during isovolumetric ventricular
contraction.
• Contains 3 leaflets-
• Anterior
• Posterior
• Septal
9.
10. AORTIC VALVE
• Situated between left ventricle and aorta.
• Opens during the left ventricular systole
• It is one of the 2 semilunar valves.
• It has characteristics more similar to the valves found in veins rather than
the heart valves.
• It has 3 cusps-
• Left
• Right
• Posterior
11.
12. PULMONARY VALVE
• Situated between the right ventricle and the pulmonary artery
• It is one of the 2 semilunar valves
• It opens during the right ventricular systole
• It has more characteristics like valves in the veins rather than heart muscle
• It has 3 cusps-
• Left
• Right
• Anterior
13.
14. CHORDA TENDINEA
• These are fibrous tendon like structure which attaches to the leaflets
from papillary muscles.
• These allow force distribution among the leaflets
• Semilunar valves do not contain chorda tendinea
15. MISC.
• Opening and closing of the valves are purely pressure dependent.
• Chorda tendinea inserts in a peculiar manner for effective closing of
the valves.
• Nodules at the tip of the leaflets make the seal tighter.
16. DEFECTS IN THE VALVES
• Stenosis
• Prolapse
• Insufficiency (regurgitation)
18. MITRAL STENOSIS
• Narrowing of the mitral valve occurs mainly due to rheumatic fever in
max. cases (99% of the cases).
• It occurs after years or decades after the patient is suffering from
rheumatic fever.
• MS is a progressive disorder that involves partial opening of the valve
which leads to passage of decreased amount of blood.
19.
20. CAUSES
• Predominantly occurs due to Rheumatic heart disease
• Calcium deposition
• Other causes like
• Congenital defects
• Radiation to the chest
• Autoimmune diseases such as lupus
21. CLINICAL MANIFESTATIONS
• Dyspnea
• Fatigue
• Decreased exercise tolerance
• AF and thromboembolism are also commonly associated with MS and
may be initial presentation.
• S1 more pronounced than S2.
26. MANAGEMENT
• Salt restriction
• Limiting exercise
• CCB
• Beta-blockers
• Anticoagulant to reduce thromboembolic risk
• Optimizing volume status with diuretics
• Percutaneous mitral valve balloon valvotomy (PMBV)
27. MITRAL REGURGITATION
• In this condition, back flow of blood occurs. This added volume of
blood in the atrium may cause atrial dilatation which may provoke
atrial fibrillation and additionally, pulmonary pressure may rise.
• Also known as mitral insufficiency.
• Common cause of mild MR is systolic dysfunction and ventricular
dilatation as because it stretches the valve apparatus causing
inefficient closing of the valve.
28.
29. CAUSES
• Mitral valve prolapse
• Ischemia
• Rheumatic fever
• In elderly, it can be occurred due to calcification of the annulus/fibrous
ring.
• Papillary muscle dysfunction after MI.
• Ruptured chordae tendinea.
• Perforated valve due to endocarditis.
30. CLINICAL MANIFESTATION
• MR is generally well tolerated by patients and remain asymptomatic
for years.
• Patient may present with
• Heart failure
• Atrial fibrillation
• Endocarditis
More commonly identified by the presence of murmur
Or as an incidental finding in echocardiography.
Pansystolic murmur at the apex is heard with radiation to the axilla.
34. MITRAL VALVE PROLAPSE
• Characterized by mitral valve becoming enlarged and floppy so that
they prolapse back into the left atrium during systole.
• Often associated with connective tissue disorders.
• Usually detected in thin, young women with chest wall abnormalities.
• Usually non progressive and benign, may be associated with
supraventricular and ventricular tachyarrhythmias.
35.
36. CAUSES
• Rheumatic heart disease
• Connective tissue disorder
• Dilatation of the left ventricle
37. CLINICAL MANIFESTATION
• Arrhythmia
• Dizziness and lightheadedness
• Shortness of breath when lying flat or during physical activity
• Fatigue
• Chest pain that is not caused by MI or CAD.
44. PROSTHETIC VALVES
• Biological
• May from other site of the patient’s
body
• May from other animals(pigs)
• Mechanical
• Metal – stainless steel
• Ceramic
• Silicone
• Polymers – pyrolytic carbon
• Type of valves
• Caged ball
• Tilting Disc
• Bi-leaflets
