Ectopic high origin of a coronary artery from the aorta--a possible cause of sudden death

Area of Science:

• Cardiovascular Pathology
• Forensic Medicine
• Anatomical Variations

Background:

• Congenital anomalies of the coronary arteries can be clinically significant and are of particular interest in forensic pathology.
• Variations in coronary artery origins can predispose individuals to cardiac events, even if asymptomatic.

Observation:

• Autopsy of a deceased male revealed a rare coronary artery anomaly.
• The right coronary artery ostium was normally positioned, while the left coronary artery ostium was pocket-shaped and abnormally high in the ascending aorta, above the sinotubular junction.

Findings:

• The primary finding was an ectopic high origin of the left coronary artery.
• This anatomical variation, though asymptomatic in life, was identified during a forensic examination.

Implications:

• This case highlights the importance of meticulous autopsy examination for identifying subtle congenital anomalies.
• Understanding such variations is crucial for accurate forensic interpretation and assessing potential causes of sudden death.
• Didactic cases like this contribute to the medical literature, aiding in the education of forensic specialists and cardiologists.
