Unique case of duplex interventricular branching from the left coronary artery

Area of Science:

• Anatomical studies
• Cardiovascular anatomy
• Human morphology

Background:

• Coronary artery anatomy is crucial for understanding cardiac function and disease.
• Variations in coronary artery branching can impact blood supply to the heart muscle.
• Knowledge of anatomical anomalies is vital for accurate diagnosis and treatment planning.

Observation:

• A rare morphological variant of the left coronary artery was identified in a female embalmed cadaver.
• The heart was supplied by dual anterior and posterior interventricular arteries, both originating from the left coronary artery.
• The distribution of the right coronary artery was observed to be significantly limited.

Findings:

• The left coronary artery exhibited an unusual branching pattern, supplying the entire heart via anterior and posterior interventricular arteries.
• This variant resulted in a diminished role of the right coronary artery in myocardial perfusion.
• The anatomical variation did not appear to cause symptoms during the individual's lifetime.

Implications:

• Awareness of this coronary artery variant is essential for interventional cardiologists and cardiothoracic surgeons.
• This knowledge can inform treatment protocols for conditions like ischemic heart disease.
• Accurate interpretation during coronary angiography is critical for effective patient management and surgical planning.
