title: Ablation of the atrioventricular junction: technique, acute and long-term results in 115 consecutive patients.
abstract: Atrioventricular junctional ablation is an attempt to interrupt conduction from the atrium to the ventricle using radiofrequency energy. The objective is to ablate the compact atrioventricular node as high as possible, leaving a stable ventricular escape rhythm. The compact node is identified in part by its relation to His recordings and partly through the known anatomy. In our series of 115 consecutive patients, atrioventricular block was achieved from the right side in 96% of patients and the remainder had the atrioventricular node ablated from the left side. Long-term success, i.e. complete heart block, was achieved in all patients. Complications in this and other series are rare, but there remains concern about sudden death in these patients.
