Intercoronary Communication between the Circumflex and Right Coronary Arteries Coexisted with Coronary Vasospasm

Area of Science:

• Cardiovascular Medicine
• Anatomical Variants
• Interventional Cardiology

Background:

• Intercoronary arterial connections represent an unusual variant of coronary anatomy.
• These connections are distinct from collateral circulation typically observed in occlusive coronary artery disease.
• Understanding these variants is crucial for accurate diagnosis and treatment planning.

Purpose of the Study:

• To report a rare case of bidirectional intercoronary communication.
• To differentiate this anatomical variant from collateral circulation in coronary artery disease.
• To highlight the coexistence with left anterior descending artery spasm.

Main Methods:

• Case report presentation.
• Review of coronary angiography findings.
• Clinical correlation of anatomical findings and symptoms.

Main Results:

• Demonstration of a rare bidirectional intercoronary connection between the left circumflex artery and the right coronary artery.
• Absence of significant occlusive coronary artery disease.
• Presence of left anterior descending artery spasm.

Conclusions:

• Intercoronary arterial connections are a rare anatomical variant with open-ended circulation.
• This case highlights the importance of recognizing such variants, especially when associated with coronary artery spasm.
• Further research may elucidate the clinical significance and management of this rare condition.
