Accessory pathway associated with an anomalous coronary sinus

Area of Science:

• Cardiology
• Embryology
• Medical Imaging

Background:

• Congenital coronary sinus anomalies are rare cardiac malformations.
• Accessory atrioventricular pathways can lead to tachyarrhythmias.
• The coexistence of these two conditions is exceptionally uncommon.

Observation:

• A male patient presented with permanent form of reciprocating tachycardia.
• The patient was diagnosed with an anomalous coronary sinus.
• Mapping the tachycardia was challenging due to the anomalous anatomy.

Findings:

• The case demonstrates the rare association between anomalous coronary sinus and accessory atrioventricular pathways.
• This association may imply a shared embryologic origin.
• The anomaly complicated electrophysiological study and mapping procedures.

Implications:

• Understanding this association is crucial for accurate diagnosis and effective treatment of tachyarrhythmias in affected individuals.
• Further research into the embryologic basis may reveal new insights into cardiac development.
• This case underscores the importance of advanced imaging and mapping techniques in complex congenital heart conditions.
