Brief summary: Transcatheter left atrial antral ablation, aiming at complete electrical isolation of the pulmonary veins (PVI), has become mainstay in atrial fibrillation (AF) treatment. This approach has been proved superior to medical rhytmh control strategy in maintaining sinus rhythm. Moreover PVI has been associated with significant survival benefit in patients with heart failure and reduced left ventricular ejection fraction. Nevertheless, despite progress in the field of catheter ablation, recurrence rates remain high.

Inhibitors of type 2 sodium- glucose co-transporter (SGLT2i) is a relatively recent addition to the array of anti-diabetic agents, becoming part of everyday clinical practice. However, although SGLT2i were first used solely as antidiabetics because of their glycosuric effect, further research demonstrated that these drugs may independently reduce cardiovascular events, especially in patients with heart failure, a benefit that was consistent among diabetic and non-diabetic patients. Moreover, pleiotropic effects have been observed, including a reno-protective action.

These findings suggest that SGLT2i mechanisms of action extend beyond the obvious increase in urinary sodium and glucose excretion. Various studies propose that these drugs promote favourable metabolic changes in myocardial energetics, while they also inhibit inflamation and sympathetic activation, resulting in restriction of induced fibrosis and structural remodeling, which are key elements in atrial fibrillation generation and maintenance.

These findings suggest that the use of SGLT2i could offer antiarrhythmic benefit by reducing and/or reversing structural and electrical remodeling, leading to the assumption that use of theese drugs could reduce recurrences after transcatheter AF ablation.

\*Eligible patients randomized in the active comparator arm will be also included in a prospective observational registry study regarding the role of SGLT2 inhibitors in post-ablation AF recurrence.
