Complete atrioventricular block DOES reduce mortality in patients with atrial fibrillation treated with cardiac resynchronization therapy.

摘要

We read with great interest the study by Tolosana et al., in which the authors affirm that atrioventricular junction (AVJ) ablation does not carry a survival benefit in patients with permanent AF undergoing CRT. The striking conclusion that 'complete atrioventricular block does not reduce long-term mortality in the AF population treated with CRT' challenges the findings of several studies and a recent meta-analysis, which are the basis for recent guidelines for the application of CRT to the AF patient population.
