Insights
A rare coronary sinus aneurysm associated with Wolff-Parkinson-White syndrome was successfully treated using percutaneous radiofrequency ablation. This minimally invasive procedure targeted the accessory pathway within the aneurysm, offering a new therapeutic option.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiac Electrophysiology
Background:
- Wolff-Parkinson-White syndrome is a pre-excitation syndrome caused by accessory pathways.
- Coronary sinus aneurysms are rare congenital or acquired dilatations of the coronary sinus.
Observation:
- A patient with Wolff-Parkinson-White syndrome and a posteroseptal accessory pathway was diagnosed with a coronary sinus aneurysm.
- Diagnostic imaging included echocardiography, coronary sinus angiography, coronary angiography, and nuclear magnetic resonance imaging.
Findings:
- Percutaneous radiofrequency current catheter ablation was performed in the isthmus of the coronary sinus aneurysm.
- The ablation procedure successfully eliminated the accessory pathway and treated the aneurysm.
Implications:
- This case demonstrates the feasibility and success of percutaneous radiofrequency ablation for treating coronary sinus aneurysms associated with accessory pathways.
- Minimally invasive ablation offers a potential treatment strategy for this rare condition, improving patient outcomes.
Abstract:
A coronary sinus aneurysm was diagnosed by means of echocardiography, coronary sinus contrast angiography, coronary angiography, and nuclear magnetic resonance imaging in a patient with Wolff-Parkinson-White syndrome caused by a posteroseptal accessory pathway. Percutaneous radiofrequency current catheter ablation performed in the isthmus of the coronary sinus aneurysm was successful.
