The presence of a common AV junction from the subcostal (en-face) view.
The identification of a common AV junction from the subcostal view had been the gold standard for diagnosis of AVSD in all the previous reports.
Data from previous studies show that AV junction ablation can improve quality of life, although it does not appear to have an impact on hospitalization rates, mortality rates, or abilities on exercise function tests; quantitative findings from elderly patients are few.
While these results provide evidence supporting the potential expansion of indications regarding the use of CRT as a first-line treatment for all permanent AF patients who must undergo AV junction ablation, we look forward to conducting additional studies to provide further confirmation that will ultimately result in the modification of treatment guidelines.
Often referred to as "ablate and pace" therapy, AV junction ablation, which produces complete AV block to assure heart rate control and rhythm regulation, followed by implantation of a cardiac pacing device, is a routine, clinically validated treatment for patients with symptomatic, drug-refractory permanent AF.
