A new diagnostic method for woven coronary artery: optical coherence tomography

Area of Science:

• Cardiology
• Medical Imaging
• Congenital Heart Disease

Background:

• Woven coronary artery is a rare congenital anomaly where epicardial coronary arteries branch into multiple thin channels before rejoining.
• This condition is generally considered benign due to normal blood flow post-anomaly.

Observation:

• A case of woven coronary artery anomaly in the left anterior descending (LAD) artery and its first diagonal (DI) branch is presented.
• The anomaly was initially misdiagnosed as coronary dissection.
• Myocardial infarction occurred secondary to the woven coronary artery anomaly.

Findings:

• Optical coherence tomography (OCT) provided definitive diagnosis of the woven coronary artery.
• OCT imaging distinguished the anomaly from coronary dissection.

Implications:

• Despite being a benign condition, woven coronary artery can lead to myocardial infarction.
• Novel OCT imaging facilitates accurate diagnosis and management of this rare anomaly.
