  We aimed to elucidate the relationship between echocardiographic data after ablation and atrial fibrillation (AF) recurrence, and to examine the difference in this relationship between paroxysmal and persistent AF. We enrolled 105 patients (72 men, paroxysmal/persistent 56/49, mean age 67 years) who underwent a single radiofrequency catheter ablation procedure. The transthoracic echocardiographic parameters were measured before ablation and at 3 days/6 months after ablation. Recurrence was observed in 30 patients (29%) at 12 months (paroxysmal 18%, persistent 41%). Stroke volume index (SVI) increased significantly in recurrence-free patients only with persistent AF shortly after ablation. Patients with persistent AF showing an increase in tricuspid regurgitation pressure gradient (ΔTRPG>0) exhibited an increase in SVI after ablation and a lower incidence of recurrence at 12 m..
