An attempt was made to ablate the slow pathway in a 45-year-old woman with recurrent SVT and reproducibly inducible typical AV nodal reentry. Using a standard 4-mm-tip electrode ablation catheter, a total of 55 applications of RF current were delivered using 50 W at several sites just outside and slightly within the coronary sinus ostium. Despite adequate tissue heating and the occurrence of an accelerated junctional rhythm with most lesions, the tachycardia remained inducible. What other approach could be used? © Springer-Verlag London Limited 2011.
