A Randomised Comparison of Left and Right Sided Approaches to Ablation of the Atrioventricular Junction

A Randomised Comparison of Left and Right Sided Approaches to Ablation of the Atrioventricular Junction

This study will compare right sided atrioventricular node ablation to left sided atrioventricular node ablation

Right-sided atrioventricular node ablation has been the initial conventional approach however up to 18.5% of patients require switching to a left sided approach or have a challenging procedure. Previous studies have found that left sided ablation is more efficacious than right-sided ablation requiring less than 5 applications of radiofrequency energy to induce atrioventricular block.

This study will compare right sided atrioventricular node ablation to left sided atrioventricular node ablation
