Pulmonary vein isolation: The impact of pulmonary venous anatomy on long-term outcome of catheter ablation for paroxysmal atrial fibrillation

Effect of left atrial volume and pulmonary vein anatomy on outcome of nMARQ™ catheter ablation of paroxysmal atrial fibrillation

“…In fact, if abnormal PV anatomy is known to little influence the ablation outcome in case of the point-by-point approach [17,18], more conflicting data have been reported with other "one-shot" technologies.…”

“…Larger series, enrolling thousands of patients, are required to assess if our strategy, to reduce the power to [15][16][17][18][19][20] W in case of electrodes in contact with the posterior wall, is effective in preventing atrioesophageal fistula.…”

Left Atrial Wall Thickness and Pulmonary Vein Size are Increased in Patients with Atrial Fibrillation Compared to Healthy Controls - A Multidetector Computed Tomography Study

“…This widely accessible imaging modality may be used to provide a more detailed anatomical evaluation and road map before ablation, in terms of both LA and PV anatomy [3,[7][8][9][10][11][12]. Recent studies indicate that LA and PV characteristics as determined by cardiac MDCT are possible important predictors of AF recurrence after ablation therapy [11,[13][14][15][16], and that the thicker the parts of the LA are, the less successful ablation therapy becomes [13,17]. In addition, it has been found that patients with persistent AF have enlarged LA cavity, decreased left ventricular function and lower success rates than other patients referred for ablation [7,9,18,19].…”

“…No association was found between PV CSA and duration (years of AF), type of AF (paroxysmal or persistent) or type of ablation (firsttime or repeat) ( Table 1, Table 2 We introduce novel information about to what extent the structure of the LA and PV anatomy is altered in AF patients compared to healthy subjects in sinus rhythm. Prior and larger population studies have described LA and PV anatomy in patients with AF [13][14][15][16]28,29].…”

The Role of Multimodality Cardiac Imaging in the Management of Patients with Atrial Fibrillation

“…PV anatomy is a powerful predictor of AF recurrence after LA ablation in cases of paroxysmal AF. McLellan et al [34] reported that the left common PV or right middle PV was protective against AF recurrence.…”
