Long-term effects of cardiac resynchronisation therapy in patients with atrial fibrillation

Abstract

Cardiac resynchronisation therapy leads to similar prognostic and symptomatic benefits in patients in AF and SR, even without atrioventricular junction ablation. Echocardiographic improvements are also comparable.

Cause-of-death analysis in patients with cardiac resynchronization therapy with or without a defibrillator: a systematic review and proportional meta-analysis

“…Two-hundred and thirtyseven were retrieved for analysis of titles and abstracts and 49 of these were selected for further analysis of the full-length article. Eighteen were considered eligible for inclusion 3,[9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] .…”

The right ventricle in patients with chronic heart failure and atrial fibrillation

“…The effect of CRT has not been compared between patients with paroxysmal and persistent AF. One of few reports regarding this subject showed, that CRT leads to similar prognostic, symptomatic and echocardiographic benefits in patients with paroxysmal, permanent AF and sinus rhythm [32]. On the other hand, lower incidence of AF episodes in patients with CRT and paroxysmal AF can be achieved as a result of improved LV and left atrial function [33,34].…”

2013 ESC Guidelines on Cardiac Pacing and Cardiac Resynchronization Therapy

“…En una revisión sistemática reciente 99 , la TRC y la ablación del nodo AV se asociaron a reducción sustancial de la mortalidad por cualquier causa (cociente de riesgos instantáneos = 0,42) y la mortalidad cardiovascular (cociente de riesgos instantáneos = 0,44) y mejoría en la clase funcional de la NYHA (cociente de riesgos instantáneos = 0,52), en comparación con la TRC sin ablación del nodo AV. Por el contrario, otros estudios 97,[103][104][105] que constataron similares mejorías de SR y FA respaldan una estrategia inicial conservadora para los pacientes con FA optimizando el tratamiento médico y programando el dispositivo de TRC para obtener un porcentaje de estimulación ventricular más alto, y reservando la ablación del nodo AV solo para pacientes con mal control del ritmo.…”
