Novel bilateral bifurcation of the coronary vasculature

Area of Science:

• Cardiovascular Anatomy
• Vascular Anomalies

Background:

• Coronary artery variations are diverse, ranging from insignificant to life-threatening.
• Many anomalies are undetected until advanced imaging or autopsy.

Observation:

• A novel bilateral bifid variation of coronary arteries was identified in a 49-year-old male cadaver.
• The coronary arteries originated from a single ostium, arising from the left and right aortic cusps.
• Immediate bifurcation occurred on both the left and right sides.

Findings:

• The right-sided variation yielded an accessory branch to the pulmonary trunk and right ventricle, and a main branch forming the posterior interventricular artery.
• The left-sided variation bifurcated into a solitary circumflex artery and branches supplying the left marginal and anterior interventricular arteries.
• This anatomical variation presented a unique branching pattern not previously documented.

Implications:

• This coronary artery anomaly might enhance survival during adverse cardiac events, potentially linked to lifestyle factors.
• The complex bilateral bifid variation presents a diagnostic challenge for clinicians, requiring careful consideration during cardiac assessments.
• Understanding such rare variations is crucial for accurate interpretation of cardiac imaging and surgical planning.
