Insights
Calcific aortic valve stenosis can cause acute myocardial infarction through calcific embolism. This condition may present as the initial symptom of aortic valve disease.
Area of Science:
- Cardiology
- Valvular Heart Disease
- Interventional Cardiology
Background:
- Calcific aortic valve stenosis is a common condition, often asymptomatic in its early stages.
- Acute myocardial infarction (MI) is a serious cardiovascular event with various potential causes.
- The link between aortic valve stenosis and embolic events is recognized but requires further elucidation.
Abstract:
A previously asymptomatic 38-year-old male with calcific aortic valve stenosis (instantaneous peak-to-peak systolic gradient: 46 mmHg) suffered an acute myocardial infarction. Coronary arteriography revealed an obstruction in a distal branch of the left circumflex artery. Left ventricular angiography demonstrated impairment of contraction of the lateral wall. We suggest that the myocardial infarction was the result of calcific embolism from the calcified aortic valve stenosis and may occur as a first manifestation of the disease.
