Radiofrequency catheter ablation can be successfully performed in the isthmus of a coronary sinus aneurysm in patients with Wolff-Parkinson-White syndrome.
Supports feasibility in rare coronary sinus aneurysm anatomy; hypothesis-generating for WPW ablation, needs prospective data.
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.
