Overview
Mitral and aortic stenosis are valvular heart diseases characterized by the narrowing of the mitral or aortic valve, respectively, leading to obstruction of blood flow and potential hemodynamic compromise 1.Diagnosis
Echocardiography: Essential for diagnosing valve stenosis, assessing severity through valve area and pressure gradients 1.
Cardiac Catheterization: Provides definitive measurement of valve area and hemodynamics, particularly useful in complex cases 1.
Electrocardiogram (ECG): Reveals signs of left ventricular hypertrophy and atrial fibrillation, common in chronic valvular disease 1.Management
Surgical Intervention: Primary treatment for severe symptomatic stenosis, including valve replacement or repair 1.
Medications: Symptomatic relief with diuretics, vasodilators (e.g., ACE inhibitors, ARBs), and anticoagulation as needed 1.
Percutaneous Interventions: Transcatheter aortic valve replacement (TAVR) for high-risk surgical candidates 1.Special Populations
Elderly: TAVR is increasingly favored over surgical aortic valve replacement due to lower perioperative risk 1.
Comorbidities: Management tailored to coexisting conditions; careful consideration of surgical risk stratification 1.Key Recommendations
Use echocardiography for initial diagnosis and follow-up assessment of valvular stenosis severity (Evidence: Moderate 1).
Consider transcatheter aortic valve replacement (TAVR) in elderly or high-risk surgical candidates (Evidence: Moderate 1).
Implement surgical valve replacement or repair for severe symptomatic mitral or aortic stenosis (Evidence: Strong 1).References
