Area of Science:
- Cardiology
- Medical Diagnostics
- Pathophysiology
Background:
- Wellens' syndrome indicates critical left anterior descending (LAD) coronary artery stenosis in acute coronary syndromes (ACS).
- Pseudo-Wellens' syndrome typically presents with normal coronary arteries on angiography.
- Myocardial bridging (MB) involves a segment of an epicardial coronary artery passing through the heart muscle.
Abstract:
Wellens' syndrome is an electrocardiographic harbinger of a critical left anterior descending (LAD) coronary artery stenosis in acute coronary syndromes (ACS), whereas pseudo-Wellens' syndrome typically has angiographically normal coronary arteries. Myocardial bridging (MB) occurs when an epicardial coronary artery segment takes a tunneled intramuscular course. We describe a rare case of MB-induced pseudo-Wellens' syndrome in a young patient presenting with unstable angina (USA).
