Coronary sinus diverticulum as a cause of resistant posteroseptal pathway ablation

Radiofrequency ablation of a posteroseptal accessory pathway associated with two diverticula of the coronary sinus.

An electrophysiological study was performed on a 39-year-old woman with recurrent palpitations. She initially presented in 1985 with atrial fibrillation, ventricular preexcitation, and a rapid ventricular response. At that time, she underwent open heart surgery, and mapping demonstrated multiple posteroseptal and left free wall accessory pathways. Accessory pathway conduction was abolished surg...

Successful Radiofrequency Catheter Ablation for Wolff-Parkinson-White Syndrome Within the Neck of a Coronary Sinus Diverticulum

Posteroseptal accessory pathways are often associated with coronary sinus diverticula. These diverticula contain myocardial coats which serve as a bypass tract. We report a 54-year-old woman who underwent radiofrequency (RF) catheter ablation for Wolff-Parkinson-White (WPW) syndrome. The surface electrocardiography (ECG) demonstrated pre-excitation, indicating a posteroseptal accessory pathway....

Supraventricular tachycardia and atrial flutter associated with a coronary sinus diverticulum: A case report

The case of a patient with narrow QRS-complex supraventricular tachycardia and atrial flutter is described. The 12-lead surface electrocardiogram (ECG) revealed sinus rhythm with ventricular pre-excitation and negative δ waves in leads II, III and aVF, indicating Wolff-Parkinson-White syndrome with a posteroseptal accessory pathway (AP). Coronary sinus angiography revealed the presence of a div...

URACHAL DIVERTICULUM WITH ALTERNATING SINUS

Urachal anomalies are exceptionally rare. They can present in different ways in childhood as well as in adults. We present an interesting case of vesico-urachal diverticulum with alternating sinus. The interesting finding in this patient was the inversion and disappearance of the umbilicus at the termination of voiding
