Aneurysm of the coronary sinus

Area of Science:

• Cardiology
• Congenital Heart Disease
• Vascular Anomalies

Background:

• Aneurysms of the coronary sinus are exceedingly rare congenital or acquired vascular anomalies.
• Diagnosis often occurs incidentally or during investigations for other cardiovascular conditions.

Observation:

• This report details two distinct cases of coronary sinus aneurysm.
• One case involved an infant diagnosed during evaluation for congenital heart disease via angiography.
• The second case was an unexpected postmortem finding in an adult patient.

Findings:

• The coronary sinus aneurysm in the infant was identified during diagnostic imaging for congenital heart disease.
• In the adult, the coronary sinus aneurysm was discovered postmortem and was not suspected clinically.
• No causal relationship was established between the adult's sudden death and the presence of the coronary sinus aneurysm.

Implications:

• Highlights the importance of recognizing coronary sinus aneurysms as a rare differential diagnosis in cardiovascular imaging.
• Suggests that coronary sinus aneurysms may not always be clinically significant or linked to adverse outcomes.
• Emphasizes the need for careful postmortem examination to identify incidental vascular anomalies.
