[Current integrated approaches for the treatment of focal atrial tachycardia]

Focal atrial tachyardia constitutes more than 10% of the supraventricular
tachycardias and it could be responsible for the initiation of other atrial
arrhythmias, like atrial fibrillation and atrial flutter. Frequently, the focal
atrial tachycardia does not respond to the medical treatment, while a definitive
cure is often obtained with radiofrequency transcatheter ablations and integrated
minimally-invasive approaches (atrial appendage clip). This paper describes
physiopathological mechanisms underlying the focal atrial tachycardia, its
anatomical localizations, the clinical patterns and the fundamentals of the
diagnosis. Finally, the more recent treatment strategies will be illustrated and
discussed.
