Insights
A case study shows embolic thrombus on mitral anulus calcification (MAC) caused retinal embolism in an elderly woman. This finding suggests MAC is a potential source of embolic stroke in older individuals.
Area of Science:
- Cardiology
- Neurology
- Ophthalmology
Background:
- Mitral anulus calcification (MAC) is increasingly recognized as a risk factor for cerebrovascular events, particularly in the elderly population.
- Previous studies have linked MAC to an increased risk of stroke.
- Atrial fibrillation and calcific emboli are known complications, but thrombus formation directly on MAC as an embolic source is less understood.
Abstract:
Embolic thrombus on mitral anulus calcification (MAC) was demonstrated in an 83-year-old woman with retinal embolism. Mitral anulus calcification has been associated with a significant increase of stroke in elderly people. Atrial fibrillation and calcific emboli have been reported, and embolic thrombus by MAC may be another potential cause.
