The term ‘flutter’ was coined to designate the visual and tactile rapid, regular atrial contraction induced by faradic stimulation in animal hearts, in contrast with irregular, vermiform contraction in atrial fibrillation (AF).1,2 On the ECG, flutter was a regular continuous undulation between QRS complexes at a cycle length (CL) of ≤250 ms (≥240 bpm). Slower tachycardias displaying discrete P…

Catheter ablation has moved from ablation of ‘simple’ substrates like accessory pathways,1 atrioventricular nodal re-entrant tachycardias (AVNRTs)2 and re-entrant or focal tachycardia (of either ventricular or atrial origin)3–5 in recent years to more complex arrhythmias such as atrial or ventricular tachycardia (VT) or fibrillation.6–8 Even patients with complex congenital heart disease that may…

With the advent of successful surgical repairs and modern diagnostic techniques, an increasing number of patients with congenital heart disease survive to adulthood. Despite these improvements, the surgical corrective atrial incisions performed during childhood lead to subsequent myocardial scarring that have the inherent risk of harbouring substrates for macro-reentrant atrial tachycardias …

Catheter ablation (CA) is a widely used first-line treatment for AF. Randomised controlled trials (RCTs) have shown its superiority to pharmacological treatment in terms of symptom control, rhythm control and mortality in selected patients; observational studies have also suggested a decreased risk of stroke.1,2 Pulmonary vein isolation (PVI) is the standard endpoint, but studies have reported…

AF is the most common sustained cardiac arrhythmia in clinical practice. It is associated with increased risk of stroke and heart failure (HF), and is a significant global health challenge.1 Catheter ablation procedures, which isolate the pulmonary veins (PV) from the left atrium and prevent AF initiation, are effective and safe treatment options, and have emerged as the preferred rhythm control…

The number of catheter ablations for atrial fibrillation (AF) treatment has gradually increased over the last 15 years since the first report on the importance of pulmonary vein (PV) foci for triggering AF.1 Catheter ablation for AF is a complex procedure with multiple steps, such as transseptal puncture, mapping of the left atrium and PVs and extensive linear ablation around PV ostia. Not…

Pioneering electrophysiology studies in the 1990s defined the anatomical boundaries of typical atrial flutter, identified regions for effective catheter ablation of this arrhythmia and described procedural endpoints to minimise recurrences after ablation. Activation and entrainment mapping demonstrated that typical flutter arises from reentry around the tricuspid annulus.1 Criteria to confirm…
