| Popis: | Background: Both the left atrial volume index (LAVI) and estimated total atrial conduction time measured using tissue Doppler imaging of the atria (PA-TDI duration) are echocardiographic parameters reflecting atrial remodeling. We investigated their prognostic value for atrial tachyarrhythmia (AF/AT) recurrence after radiofrequency catheter ablation (RFCA) of paroxysmal atrial fibrillation (PAF). Methods and Results: We analyzed the data for 100 consecutive patients with drug-refractory PAF who underwent RFCA. The correlation between the LAVI and PA-TDI was extremely weak (r=0.26, P |
