During the past decade, catheter ablation of atrial fibrillation (AF) has evolved rapidly from
an investigational procedure to its current status as a commonly performed ablation�…

Clinical electrophysiology has made the traditional classification of rapid atrial rhythms into
flutter and tachycardia of little clinical use. Electrophysiological studies have defined multiple�…

During the past decade, catheter ablation of atrial fibrillation (AF) has evolved rapidly from a
highly experimental unproven procedure, to its current status as a commonly performed�…

The present treatment of atrial fibrillation by radiofrequency catheter ablation requires long
continuous lesions in the thin walled left atrium where side effects may lead to serious�…

Adequate catheter-tissue contact facilitates efficient heat energy transfer to target tissue.
Tissue contact is thus critical to achieving lesion transmurality and success of�…

The era of catheter ablation for the treatment of arrhythmias began in 1981, when Dr. Melvin
Scheinman performed the first atrioventricular junction ablation using direct-current shocks�…

Atrial fibrillation is the most common arrhythmia managed in clinical practice and it is
associated with an increased risk of mortality, stroke and peripheral embolism�…

Background: Although linear ablation of the right atrial isthmus in patients with isthmus‐
dependent atrial flutter can be highly successful, recurrences and complications occur in�…

Background—Cavotricuspid isthmus (CTI) characteristics are rarely documented when
comparing catheters in radiofrequency ablation (RFA) of atrial flutter (AFL). Our objectives�…

Aims Magnetic resonance imaging (MRI) in the context of electrophysiology (EP) studies
facilitates visualization of complex three-dimensional anatomy and the underlying�…
