Mitral annular calcification (MAC) can cause left ventricular outflow tract (LVOT) obstruction. Alcohol septal ablation successfully treated a high-risk patient with MAC-related LVOT obstruction.
Area of Science:
- Cardiology
- Interventional Cardiology
Background:
- Mitral annular calcification (MAC) can extend into the left ventricular outflow tract (LVOT).
- This extension can cause dynamic obstruction, mimicking hypertrophic cardiomyopathy.
- Management is complex in patients with prior valve surgery.
