Final answer:
Surgical repair or replacement may be indicated for chronic mitral regurgitation if the condition is severe and causing symptoms or complications.
Step-by-step explanation:
Chronic mitral regurgitation is a condition where the blood flows backward through the mitral valve of the heart. Surgical repair or replacement may be indicated in cases where the regurgitation is severe and causing symptoms or complications. Some indications for surgical intervention include:
- Severe symptoms such as shortness of breath, fatigue, and chest pain
- Left ventricular dysfunction or enlargement
- Significant regurgitation on imaging tests
- Development of secondary complications such as atrial fibrillation or pulmonary hypertension
