Single Coronary Artery Anomaly in a Woman With Acute ST-Segment Elevation Myocardial Infarction

Area of Science:

• Cardiology
• Interventional Cardiology
• Congenital Heart Disease

Background:

• Acute myocardial infarction (MI) is a leading cause of mortality.
• Coronary artery anomalies are uncommon but can lead to significant cardiac events.
• Single coronary artery anomaly is a rare congenital condition.

Purpose of the Study:

• To report a case of acute inferior ST-segment elevation myocardial infarction (STEMI) secondary to a rare single coronary artery anomaly.
• To highlight the diagnostic and therapeutic challenges posed by such anomalies.

Main Methods:

• Coronary angiography was performed to diagnose the coronary artery anomaly and identify the culprit lesion.
• Percutaneous coronary intervention (PCI) with stenting was utilized for revascularization.

Main Results:

• A 65-year-old woman presented with acute inferior STEMI.
• Coronary angiography revealed a rare single coronary artery anomaly.
• A critical stenosis in the mid right coronary artery was identified as the culprit lesion.
• Successful PCI with stenting was performed, restoring coronary blood flow.

Conclusions:

• This case underscores the importance of considering rare coronary anomalies in the etiology of myocardial infarction.
• Prompt diagnosis and intervention, including percutaneous revascularization, are crucial for managing STEMI in the setting of coronary anomalies.
