Abnormal Atrioventricular Valve Physiology C4703462
A problem with how the heart's atrioventricular valves function, affecting blood flow between heart chambers. This can cause symptoms like fatigue and shortness of breath, managed with medications or surgery.

Signs and symptoms
Common signs and symptoms that may indicate this condition.
Warning signs - seek immediate care
Fainting
Sudden loss of consciousness due to inadequate blood flow to the brain from severe valve dysfunction.
Fainting is a medical emergency. Call emergency services immediately as it may indicate a life-threatening arrhythmia or severe valve obstruction.
Paroxysmal nocturnal dyspnea
Sudden shortness of breath that awakens a person from sleep, caused by fluid redistribution while lying flat.
This is a serious symptom requiring prompt medical evaluation, as it indicates significant heart dysfunction.
Fatigue
(constitutional)Persistent tiredness and reduced energy levels due to decreased cardiac output and inefficient blood circulation.
Frequency: 60-80% of patients
Shortness of breath on exertion
(respiratory)Difficulty breathing during physical activity or exercise, caused by increased pressure in the pulmonary vessels.
Frequency: 60-80% of patients
Palpitations
(cardiovascular)Awareness of rapid, fluttering, or irregular heartbeat, often due to valve dysfunction affecting heart rhythm.
Frequency: 40-60% of patients
Chest discomfort
(cardiovascular)Pressure, tightness, or pain in the chest area, often triggered by physical exertion or stress.
Frequency: 30-50% of patients
Peripheral edema
(cardiovascular)Swelling in the legs, ankles, or feet due to fluid accumulation from impaired heart function.
Frequency: 30-50% of patients
Dizziness or lightheadedness
(neurologic)Feeling faint or unsteady, caused by reduced blood flow to the brain due to valve dysfunction.
Frequency: 15-25% of patients
Dry cough
(respiratory)Persistent dry cough that may worsen when lying down, often due to fluid backup in the lungs.
Frequency: 25-40% of patients
Diagnosis and tests
How this condition is diagnosed and what test results mean.
Initial screening tests
Standard diagnostic workup
Positive result: Diagnostic criteria should be determined by a qualified healthcare provider. [Content pending medical review.]
Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Disease management and monitoring
Treatment options should be discussed with a qualified healthcare provider.
Rate Control Medications
Pharmacological agents to control heart rate and improve valve function by reducing excessive cardiac workload.
Balloon Valvuloplasty
Catheter-based procedure to widen a narrowed valve opening and improve blood flow dynamics.
Additional treatment options
Valve Replacement
Surgical replacement of the dysfunctional valve with a mechanical or biological prosthesis.
surgicalCardiac Function Monitoring
Regular assessment of valve hemodynamics through echocardiography and clinical evaluation.
monitoringSodium Restriction
Low-sodium diet to reduce fluid retention and decrease cardiac workload.
