Abstract
Mapping uses a combined anatomy- and electrogram-guided approach. The right-sided approach target is just proximal to or below the His bundle electrode position on the fluoroscopic view, or at the proximal His location. The left-sided approach target is just below the aortic valve at the septal site where a His potential can be recorded. If the His potential is not recorded at the upper septal site, it may be recorded in the noncoronary sinus cusp. Sources of difficulties include inability to record the His potential and failure of the right-sided approach. Successful atrioventricular junction ablation allows 100% biventricular pacing with CRT in patients with AF and reduced ventricular function. AV node modification is not recommended because of lack of benefit and higher risks as compared with complete AV junction ablation with pacemaker.
