Systolic total narrowing of left anterior descending coronary artery and flow interruption secondary to myocardial bridge: a rare case report and review of literature.
A 33-y-old man was admitted to the emergency department with sudden onset of severe substernal chest pain radiating to the left arm and neck. No pathological signs were recorded upon physical examination. The admission electrocardiogram (ECG) recorded during chest pain showed a large anterior wall myocardial infarction. Intravenous (IV) infusion of 1.5 million units of streptokinase over 1 h was initiated. Coronary angiography revealed total narrowing and flow interruption in the midsegment of the left anterior descending (LAD) coronary artery secondary to a myocardial bridge during systole and disappearance with diastole. He was discharged on aspirin (300 mg/d), metoprolol (100 mg/d), enalapril (10 mg twice daily), and atorvastatin (40 mg/d) treatment at the follow-up period.
