May explain refractory endocardial ablation cases; leaves open systematic epicardial mapping studies.
Case Report (n=1)
The identification of an epicardial accessory pathway from the right atrial appendage to the right ventricle provides anatomical insight that may explain some failures of endocardial radiofrequency catheter ablation.
Milstein et al. (1997) conducted a case report in Accessory atrioventricular connection (n=1). An unusually located accessory atrioventricular connection was found bridging the atrioventricular ring epicardially from the base of the right atrial appendage directly to the right ventricle.
