Summary
Single coronary artery, once considered minor, can cause serious complications like angina and myocardial infarction. This report details three complex cases, highlighting the anomaly's significant clinical importance.
Area of Science:
- Cardiology
- Congenital Heart Disease
Background:
- Single coronary artery (SCA) is a rare congenital anomaly.
- Historically underestimated, SCA is increasingly recognized for potential complications.
Observation:
- Three patients with SCA (Smith's type 2) presented with diverse complications.
- Case 1: 56-year-old female with angina, 90% left circumflex artery stenosis.
- Case 2: 48-year-old male with chest pain/syncope, 75% right coronary artery stenosis.
- Case 3: 69-year-old male with chest pain, no significant stenosis.
Findings:
- SCA can be associated with significant coronary artery stenosis.
- Complications include angina, myocardial infarction, and arrhythmia.
- Percutaneous coronary intervention (PCI) may improve outcomes in select cases.
Implications:
- SCA requires careful evaluation due to its potential for severe cardiovascular events.
- Early diagnosis and management are crucial for preventing adverse outcomes.
- This highlights the importance of recognizing SCA in patients with unexplained cardiac symptoms.
