Congenital absence of left circumflex artery detected by computed tomography coronary angiography: a case report

Area of Science:

• Cardiology
• Medical Imaging
• Congenital Anomalies

Background:

• The congenital absence of the left circumflex artery (LCx) is an exceptionally rare coronary artery anomaly.
• Despite its rarity, this condition is generally considered benign.
• Atypical chest pain can be a presenting symptom.

Purpose of the Study:

• To report a case of congenital absence of the LCx.
• To highlight the diagnostic utility of computed tomography coronary angiography (CTCA) in identifying coronary anomalies.
• To discuss the clinical presentation of this rare anomaly.

Main Methods:

• Computed tomography coronary angiography (CTCA) was utilized for diagnosis.
• Review of patient's clinical presentation and imaging findings.
• Literature review on congenital absence of the LCx.

Main Results:

• CTCA successfully identified the congenital absence of the LCx.
• The patient presented with atypical chest pain.
• The anomaly was confirmed as benign.

Conclusions:

• Congenital absence of the LCx is a rare but benign coronary anomaly.
• CTCA is the gold standard for diagnosing coronary artery anomalies.
• This case underscores the importance of considering rare anomalies in patients with atypical symptoms.
