Diagnosis of Coronary Sinus Diverticulum in Wolff‐Parkinson‐White Syndrome Using Coronary Angiography

STAMATO, N. et al .: Diagnosis of Coronary Sinus Diverticulum in Wolff‐Parkinson‐White Syndrome Using Coronary Angiography The entity of Wolff‐Parkinson‐White Syndrome and coronary sinus diverticula when the bypass tract is posteroseptal in location has been described recently. The presence of this diverticulum may complicate arrhythmia surgery and could potentially add to the risk of catheter ablation. We describe a case of Wolff‐Parkinson‐White Syndrome in which the diagnosis of a coronary sinus diverticulum was made preoperatively using late‐phase coronary angiography and suggest angiography be considered in patients with posteroseptal bypass tracts prior to surgery or catheter ablation.
