In this case report the electrophysiological findings in a 24 year old female patient are demonstrated. For about 12 years she suffered from recurrent atrioventricular reentrant tachycardia with a rate of 230 beats per minute. Electrophysiological study resulted in diagnosis of a posteroseptal accessory pathway. Ablation was attempted primarily from a left ventricular access, but the pathway could not be reached from this position. After contrasting the coronary sinus a large coronary sinus aneurysm could be diagnosed. The accessory pathway was located in the "neck"-region of the aneurysm. By application of radiofrequency current in this location the bypass tract could be ablated. This case report shows that accessory pathways in coronary sinus aneurysms can be ablated without complications in this location.
