Disease category
Valvular heart disease is a category of diseases in which one or more heart valves fail to open or close properly, potentially affecting blood flow and cardiac workload.
Core mechanism
It may arise from congenital valve formation abnormalities, or develop acquiredly depending on age and heart-related conditions such as rheumatic fever, endocarditis, myocardial infarction, and heart failure.
Main causes · Related factors
The main problems are regurgitation (leaking), stenosis (insufficient opening), and atresia (failure of an exit to form); both issues may occur together.
Representative manifestations
Representative clinical manifestations include dyspnea, fatigue, edema, chest pain during exertion, arrhythmia, dizziness, or syncope.
Individual variation
Advanced age, hypertension, diabetes, hyperlipidemia, obesity, lack of physical activity, family history of cardiovascular disease, and congenital aortic valve abnormalities can increase the risk, and individual prognosis varies.
Diagnosis
While some people live their entire lives without symptoms, the disease may progress slowly; if untreated, increased cardiac workload can lead to heart failure, stroke, thrombosis, or sudden cardiac arrest.
Management
Diagnosis is based on medical history and physical examination; if a heart murmur is heard, cardiac function, valve structure, and blood flow are evaluated primarily using echocardiography.
Treatment/Research Status
Severity and the need for treatment cannot be determined solely by heart murmurs or imaging findings; valve type, symptoms, cardiac function, and comorbidities must be interpreted together.
Read Evidence
Management is conducted by evaluating symptoms and cardiac load while controlling relevant cardiovascular risks, and considering valve repair or replacement if necessary.
Key Precautions
The current pillars of treatment are medications that help with symptoms and cardiac function, lifestyle management for heart health, and valve repair or replacement.

At a Glance

Valvular heart disease is a category of diseases in which one or more heart valves fail to open or close properly, potentially affecting blood flow and cardiac workload.

Representative clinical manifestations include dyspnea, fatigue, edema, chest pain during exertion, arrhythmia, dizziness, or syncope.

How the disease works

It may arise from congenital valve formation abnormalities, or develop acquiredly depending on age and heart-related conditions such as rheumatic fever, endocarditis, myocardial infarction, and heart failure.

The main problems are regurgitation (leaking), stenosis (insufficient opening), and atresia (failure of an exit to form); both issues may occur together.

Variations in presentation among individuals

Advanced age, hypertension, diabetes, hyperlipidemia, obesity, lack of physical activity, family history of cardiovascular disease, and congenital aortic valve abnormalities can increase the risk, and individual prognosis varies.

The broad framework of diagnosis and management

While some people live their entire lives without symptoms, the disease may progress slowly; if untreated, increased cardiac workload can lead to heart failure, stroke, thrombosis, or sudden cardiac arrest.

Diagnosis is based on medical history and physical examination; if a heart murmur is heard, cardiac function, valve structure, and blood flow are evaluated primarily using echocardiography.

Current status of treatment

Severity and the need for treatment cannot be determined solely by heart murmurs or imaging findings; valve type, symptoms, cardiac function, and comorbidities must be interpreted together.

Management is conducted by evaluating symptoms and cardiac load while controlling relevant cardiovascular risks, and considering valve repair or replacement if necessary.

The current pillars of treatment are medications that help with symptoms and cardiac function, lifestyle management for heart health, and valve repair or replacement.

How to read clinical trials

Follow-up observation must confirm symptoms, cardiac function, valvular changes, and post-treatment complications; the registration of NCT04350658 in ClinicalTrials.gov only indicates the existence of an observational study and does not prove efficacy or standard treatment.

Points to verify during clinical consultations

In clinical practice, it is important to verify the location and type of the valve, changes in symptoms, test results, the necessity of surgery or procedures, the benefits and burdens of medication, follow-up schedules, and emergency symptoms.
