[Dual left arterior coronary artery: a case report]

Area of Science:

• Cardiovascular Medicine
• Anatomical Variations
• Interventional Cardiology

Background:

• Coronary artery anomalies are rare congenital conditions that can predispose individuals to various cardiovascular events.
• A dual left anterior descending artery (DLAD) is an exceptionally uncommon anomaly, presenting unique diagnostic and therapeutic challenges.

Observation:

• A 43-year-old male presented with symptoms of angina pectoris.
• Multispiral computed tomography (CT) of the coronary arteries revealed a rare Type IV dual left anterior descending artery anomaly.
• The CT scan also identified significant atherosclerotic lesions within the coronary arteries.

Findings:

• The patient exhibited a rare Type IV dual left anterior descending artery.
• Significant atherosclerotic disease coexisted with the anomalous coronary anatomy.
• Hemodynamically significant stenoses were identified in the affected coronary arteries.

Implications:

• This case highlights the importance of advanced imaging techniques in diagnosing rare coronary artery anomalies.
• Successful percutaneous coronary intervention (PCI) with stenting demonstrates the feasibility of managing atherosclerotic disease in the context of complex anatomy.
• Understanding such anomalies is crucial for accurate diagnosis and effective treatment strategies in cardiovascular medicine.
