Role of Atrioventricular Junctional Ablation and Cardiac Resynchronization Therapy in Patients with Chronic Atrial Fibrillation.

There remains a great deal of uncertainty whether general application of cardiac resynchronization therapy (CRT) to patients with atrial fibrillation (AF) provides any benefit assuming all other eligibility criteria are met. Preliminary observations suggest that performing atrioventricular junction ablation can improve the results of CRT in patients with AF by rendering the patient pacemaker dependent. Ongoing randomized clinical trials may provide more definitive answers in the future.
