Implication
CS diverticula associate with accessory pathways in EPS patients; leaves open whether targeted imaging improves ablation outcomes.
Structured PICO
What is the incidence of coronary sinus anomalies and the size of the coronary sinus ostium in patients undergoing electrophysiologic study?
P
Population
204 consecutive patients (82 women, 122 men, age 45 +/- 15 years) referred for electrophysiologic study and catheter ablation of various tachyarrhythmias (120 with accessory pathways, 43 AVNRT, 12 atrial tachycardia/fibrillation, 15 ventricular tachycardia, 14 unexplained syncope)
I
Intervention
Retrograde angiography of the coronary sinus (CS angiogram)
O
Outcome
Incidence of coronary sinus anomalies and diameters of the coronary sinus ostiumsurrogate
Coronary sinus anomalies such as diverticula are predominantly found in patients with accessory pathway-related tachycardias, while CS ostium size does not significantly differ in AVNRT patients compared to controls.
