Catheter ablation for atrial fibrillation
Catheter ablation for atrial fibrillation is a well established and effective
therapeutic option in patients without CHF
ESC recommendations for left atrial ablation
Congestive heart failure and atrial fibrillation
are the two major „epidemics” of cardiovascular
disease
HF triggering the development of AF and vice versa
Both of them increase the morbidity and mortality in
a synergistic manner
Heart Failure and Atrial Fibrillation
Limited data on the impact of AF ablation on:
quality of life, left ventricular function, exercise
capacity and mortality
The effects of ablation for atrial fibrillation in
HF patients is still uncertain
What is the Role and Place of Catheter
Ablation for Atrial Fibrillation Treatment
in Congestive Heart Failure?

- broad inclusion criteria, ie. EF<50%
- small number of recruited patients (<500 pts)
- lack of the assessment of AF ablation impact
on mortality

Complications of AF catheter ablation
Complications of AF catheter ablation
Summary
1. The incidence of recurrent AF after PV isolation is higher in
patients with CHF and therefore a repeated procedure is required
more frequently
2. The maintenance of a sinus rhythm by AF catheter ablation in
patients with CHF seems to improve the following :
LV systolic function
exercise capacity
quality of life

Long-term survival in patients undergoing CRT:
the importance of performing A-V junction ablation
in patients with permanent AF
Gasparini, EHJournal 2008
Conclusions
The pursue for the sinus rhythm maintenace by
means of catheter ablation requires an individual
clinical approach based on:
- the stage af atrial diease, including the type of AF
- the presence and severity of uderlying
cardiovascular disease
- potential treatment alternative
- patient’s preference
Conclusions
The ultimate assessment of the role and impact of
AF catheter ablation on clinical outcome in CHF
needs further investigation
Conclusions
a-v node ablation
A-V node ablation seems not to be as effective as
PVI in patients with CHF
It is reasonable to consider a-v node ablation in
CRT patients with permanent AF and suboptimal
percentage of CRT pacing
