Overview
Rheumatic aortic stenosis is a chronic valvular heart disease characterized by progressive narrowing of the aortic valve due to fibrous and calcific changes, leading to left ventricular hypertrophy and reduced cardiac output 1.Diagnosis
Clinical Presentation: Symptoms include angina, dyspnea, syncope, and heart failure 1.
Echocardiography: Essential for measuring valve area, assessing valve morphology, and grading severity (e.g., valve area ≤1 cm2 indicates severe stenosis) 1.
Doppler Ultrasound: Evaluates pressure gradients across the valve 1.Management
Balloon Valvuloplasty: In severe cases, double balloon aortic valvuloplasty can increase valve area; mean increase from 0.7 to 1.1 cm2 observed 1.
Surgical Aortic Valve Replacement (AVR): Recommended for high-risk surgical candidates or those with failed valvuloplasty 1.Special Populations
No Specific Data Provided: Abstracts do not cover special populations such as pregnancy, pediatrics, elderly, or comorbidities 1.Key Recommendations
Consider Balloon Valvuloplasty for Severe Rheumatic Aortic Stenosis: Can effectively increase valve area, though efficacy may vary with commissural calcification 1 (Evidence: Moderate).
Evaluate Surgical AVR for Patients with Failed Balloon Valvuloplasty or High Surgical Risk: Indicated for optimal long-term outcomes 1 (Evidence: Expert opinion).
Utilize Echocardiography for Diagnosis and Monitoring: Essential for assessing valve area and severity grading 1 (Evidence: Strong).References
