Atrial Coronary Arteries: Anatomy And Atrial Perfusion Territories

Area of Science:

• Cardiovascular Anatomy
• Cardiac Electrophysiology
• Medical Education

Background:

• Coronary circulation research has historically prioritized ventricular anatomy due to coronary artery disease's impact.
• Atrial fibrillation and tachyarrhythmias significantly contribute to cardiovascular morbidity and mortality.
• Current understanding of atrial coronary anatomy is limited, hindering mechanistic research and therapeutic advancements.

Purpose of the Study:

• To delineate the anatomical courses and perfusion territories of key atrial coronary branches.
• To clarify and standardize the nomenclature of atrial coronary vessels.
• To propose unifying anatomical concepts of atrial circulation for improved clinical procedures.

Main Methods:

• Systematic review of existing literature on atrial coronary anatomy.
• Analysis of anatomical variations and distribution patterns of atrial coronary arteries.
• Synthesis of data to establish standardized nomenclature and conceptual framework.

Main Results:

• Detailed description of the anatomical courses of major atrial coronary arteries.
• Identification of specific perfusion territories supplied by these vessels.
• Establishment of a clarified and unified nomenclature for atrial coronary anatomy.

Conclusions:

• A comprehensive understanding of atrial coronary anatomy is essential for advancing research and clinical interventions for atrial arrhythmias.
• Standardized nomenclature and anatomical concepts will facilitate communication and improve outcomes in electrophysiology and cardiac surgery.
• This review provides a critical foundation for future studies on atrial circulation and related pathologies.
