Is radiofrequency catheter ablation of accessory pathway-mediated tachycardia a safe and effective long-term therapy?
Radiofrequency catheter ablation has high immediate success rate and long-term recurrence of accessory pathway conduction or tachycardia. Right free wall or right posteroseptal pathways are associated with higher incidence of initial ablation failure and short- to medium-term recurrence.
The findings presented here confirm and extend the argument for Sry3 as one of the genes responsible for the SHR hypertensive Y chromosome phenotype and are consistent with increased tissue RAS activity due to Sry3 and increased sodium reabsorption.
