Since the fi rst publication proving the causal relation between electrically active muscular sleeves
in the pulmonary veins (PV) and the triggering of paroxysmal atrial fi brillation (AF) by ectopic beats
originating from them, numerous endocardial ablation techniques have been used to eliminate
this arrhythmia. Although well established as a standard procedure in the treatment of atrial
fi brillation, point-to-point radiofrequency ablation remains a challenging procedure, in which
manual operator skills and experience is highly variable. This currently translates in variable
success rates and high complication rates, making the risk-benefi t evaluation of this procedure
diffi cult to assess. Several devices have been engineered to simplify the circumferential ablation,
with the aim of permitting less experienced operator to achieve the endpoint of PV isolation
with reasonable procedure and fl uoroscopy times, and without a higher risk of complications.http://repub.eur.nl/res/pub/21746/101125_Van%20Belle%2C%20Yves%20L.E.pdf
