These measurements should not inform AVNRT risk stratification or ablation; hypothesis-generating for other contributors in observational data.
Does the size, morphology, and anatomical relationship of the coronary sinus ostium to the His bundle differ between patients with and without AV nodal reentrant tachycardia?
The anatomical characteristics of the coronary sinus ostium and its distance to the His bundle vary widely but do not differ between patients with and without AV nodal reentrant tachycardia.
Hummel et al. (1995) studied this question.
