Valvular Heart Disease Nursing Care
Every valve problem is one of two things: a valve that won’t open (stenosis, a pressure problem) or one that won’t close (regurgitation, a volume problem). Get that split and the murmurs, the heart-failure pattern, and the nursing care all follow.

Overview
The heart’s four valves keep blood moving forward. When a valve is diseased it either narrows (stenosis) — forcing the chamber behind it to generate higher pressure to push blood through — or it leaks (regurgitation/insufficiency) — letting blood flow backward and overloading the chamber with volume. Either way, the chamber eventually fails, and blood backs up. The most clinically important lesions involve the mitral and aortic valves. Common causes are rheumatic heart disease (classically mitral stenosis), age-related calcific degeneration (aortic stenosis), endocarditis, and congenital valves.
Key Concepts
Stenosis = pressure overload
A stiff, narrowed valve makes the chamber behind it work against high resistance and hypertrophy. Aortic stenosis is the classic — the LV pumps against a tight valve and eventually can’t keep up, producing the triad SAD: Syncope, Angina, Dyspnea (the onset of symptoms marks a sharp drop in survival without valve replacement).
Regurgitation = volume overload
A leaky valve sends blood backward, so the chamber dilates to handle the extra volume. Mitral regurgitation overloads the left atrium and lungs; aortic regurgitation overloads the LV with a wide pulse pressure. Regurgitation tolerates a slow course but can decompensate acutely (e.g., after endocarditis or papillary-muscle rupture in MI).
Mitral stenosis & atrial fibrillation
Mitral stenosis (usually rheumatic) backs blood up into a stretched left atrium → pulmonary congestion and, very commonly, atrial fibrillation with its stroke/embolism risk (hence anticoagulation). Think dyspnea, hemoptysis, and a-fib in a patient with a history of rheumatic fever.
Murmurs localize the lesion
The timing (systolic vs diastolic) and location point to the valve: aortic stenosis and mitral regurgitation are systolic; aortic regurgitation and mitral stenosis are diastolic. (See the murmurs reference.)
Assessment Findings
Listen for a murmur and note its timing and where it’s loudest. Screen for the consequences: heart-failure signs (dyspnea, orthopnea, fatigue, crackles, edema, JVD), atrial fibrillation (irregularly irregular pulse), aortic-stenosis red flags (exertional syncope, angina, dyspnea), and a wide pulse pressure with bounding pulses in aortic regurgitation. Assess activity tolerance and ask about a history of rheumatic fever, IV drug use, or prior valve disease. Diagnosis is confirmed by echocardiography.
Nursing Priorities
Manage heart failure and rhythm
Monitor for and treat heart failure (diuretics, sodium/fluid balance, daily weights) and watch for atrial fibrillation. For a-fib (especially with mitral stenosis), expect anticoagulation and rate control.
Respect aortic-stenosis hemodynamics
Severe aortic stenosis is preload-dependent — avoid aggressive vasodilators/diuresis that drop preload, and treat exertional syncope/angina as a warning to escalate. Symptomatic severe AS needs valve replacement.
Prepare for repair or replacement
Definitive treatment is valve repair or replacement — surgical (mechanical or bioprosthetic valve) or transcatheter (e.g., TAVR for aortic stenosis). Provide pre/post-procedure teaching and anticipate lifelong anticoagulation with a mechanical valve.
Prevent endocarditis
Diseased and prosthetic valves are at risk for infective endocarditis — reinforce dental/oral hygiene and antibiotic prophylaxis when indicated.
Therapeutic Communication Considerations
Valve disease is often slow and silent until symptoms arrive, then suddenly serious — patients may underestimate “just a murmur” or, conversely, fear open-heart surgery. Explain why symptoms like new shortness of breath, fainting, or chest pain are important to report, and walk through what valve repair/replacement involves to reduce surgical anxiety. For patients facing lifelong anticoagulation, address the lifestyle adjustments honestly. Acknowledge the activity limits the disease imposes and partner on realistic goals.
Patient & Family Education
Teach the symptoms to report: worsening dyspnea, orthopnea, swelling, palpitations/irregular pulse, fainting, or chest pain. Cover daily weights and when to call for weight gain or worsening edema. For atrial fibrillation, teach anticoagulation safety. After valve replacement, teach mechanical-valve anticoagulation (lifelong warfarin with INR monitoring, consistent vitamin-K intake, bleeding precautions) vs the limited durability of bioprosthetic valves, and endocarditis prevention (dental care, prophylaxis when indicated, prompt treatment of infections). Reinforce dental and oral hygiene and carrying valve/anticoagulation information.
NCLEX Pearls
- ✦Stenosis = valve won't open (pressure overload, hypertrophy); regurgitation = valve won't close (volume overload, dilation).
- ✦Aortic stenosis triad = Syncope, Angina, Dyspnea (SAD); symptom onset signals the need for valve replacement (often TAVR).
- ✦Mitral stenosis (usually rheumatic) → left atrial enlargement, pulmonary congestion, and atrial fibrillation → anticoagulate.
- ✦Murmur timing localizes it: AS and MR are systolic; AR and MS are diastolic.
- ✦Mechanical valves require lifelong anticoagulation (warfarin/INR); diseased and prosthetic valves need endocarditis prophylaxis.
