mitral valve calcification
Etiology:
- may be related to
- diabetes mellitus
- hypertension
- hyperlipidemia
- secondary hyperparathyroidism from renal failure
Epidemiology:
- often detected on routine chest radiographs in elderly patients
Pathology:
- generally unrelated to clinical symptoms
Special laboratory:
- transthoracic echocardiography may reveal mitral regurgitation & mitral stenosis
Radiology:
- often detected on routine chest radiographs in elderly patients
- computed tomography reveals calcification of the mitral-valve annulus
Complications:
- complete heart block
- mitral regurgitation
- mitral stenosis (less often)
Management:
- generally intervention not indicated
- mitral valve replacement may be indicated if heart failure due to mitral regurgitation or mitral stenosis
General
