Cardiac resynchronization therapy in patients undergoing atrioventricular junction ablation for permanent atrial fibrillation: a randomized trial

Abstract: In patients undergoing 'Ablate and Pace' therapy for severely symptomatic permanent atrial fibrillation, CRT is superior to RV apical pacing in reducing the clinical manifestations of HF. (ClinicalTrials.gov number: NCT00111527).

“…Six months after AVJA, RV pacing was associated with a significantly greater increase in left atrial volume, LV end‐systolic volume, and LV mass compared with biventricular pacing. To assess hard clinical outcomes, Brignole et al reported on 186 patients with permanent AF who underwent AVJA and were then randomized to receive either biventricular or RV‐only pacing 5. The primary end point was a composite of death from HF, hospitalization attributable to HF, and worsened HF, with a median follow‐up of 20 months.…”

“…Although right ventricular (RV) pacing has been most commonly used, concerns have been raised about the deleterious impact of RV pacing on clinical outcomes; in some patients, clinical deterioration can occur within months of pacemaker implantation 3. Thus, several investigators have explored the role of biventricular pacing in this patient population 4, 5, 6, 7, 8. However, these studies have produced conflicting results, likely in part because of the relatively few patients enrolled and variability in follow‐up duration.…”

“…A pesar de la falta de evidencia clara de estudios controlados y aleatorizados, en los cuales solo se incluyó a 200 pacientes con FA permanente 89,90 , el 23% de los pacientes que recibieron TRC tenían FA en un registro europeo de práctica clínica y un número aún mayor podría ser elegible w146,w147 . Los pacientes con FA se diferencian de los pacientes con SR porque el ritmo ventricular es irregular y, por lo general, más rápido.…”

“…Aunque los resultados fueron neutros en el análisis por intención de tratar, el análisis por protocolo incluyendo solo a los pacientes con una tasa de estimulación biventricular > 85% sí mostró una mejoría leve pero significativa del estado funcional a los 6 meses y a 1 año de seguimiento 90,93 . En el estudio APAF 89 , la indicación de TRC fue principalmente para ablación del nodo AV; en los subgrupos de pacientes con FEVI bajo, clase NYHA ≥ III y QRS ≥ 120 ms, la TRC redujo considerablemente el objetivo primario, que Referencias en que se apoya la recomendación.…”
