Methods and results We analysed data from 368 ablation procedures of 279 consecutive patients referred for PVA due to drug-refractory symptomatic AF (age 62 +/- 10; 58% men; 71% paroxysmal AF). Prior to the procedure, all patients underwent ECG-gated 64-MDCT scan for assessment of LA and PV anatomy, LA thrombus evaluation, LA volume estimation, and electroanatomical mapping integration. Within a mean follow-up of 356 +/- 128 days, 64% of the patients maintained sinus rhythm after the initial ablation, and 84% when including repeat PVA. LA diameter (P = 0.004), LA volume (P = 0.002), and type of AF (P = 0.001) were independent predictors of AF recurrence in univariate analysis. There was a relatively low correlation between the echocardiographic LA diameter and LA volume from MDCT (P = 0.01, r = 0.5). In multivariate analysis, paroxysmal AF (P < 0.006) and LA volume below the median value of 106 mL (P = 0.042) were significantly associated with the success of PVA, whereas LA diameter was not (P = 0.245). Analysing receiver-operator characteristics, the area under the curve for LA volume was 0.73 (P = 0.001) compared with 0.60 (P = 0.09) for LA diameter from echocardiography.

TTE and CMR were independently analysed regarding the presence of intracardiac thrombus formation, masses and related size, dimensions, shape and signal characteristics. TTE depicted intracavitary thrombus formation in 40/171 patients (23.4 %) and intracardiac mass in 12/171 patients (7.0 %). All masses revealed in TTE were correctly detected on CMR and confirmed by histology. However, CMR showed 15 additional thrombi and 3 additional intracardiac masses (p = 0.001) that were not seen in TTE. Patients with poor systolic function (LVEF < 30 %) had misleading results when referred to TTE (19 vs. 27 thrombi detected, p < 0.01). The detection of intracardiac masses or thrombi was not significantly different in patient with LVEF > 30 %, whereas CMR was superior when the LVEF was < 30 %. Routine TTE in patients with CAD leads to lower detection rates of intracardiac masses and thrombus formation in patients with severely impaired EF.

We analyzed if concomitant antiarrhythmic drug (AAD) therapy significantly alters early recurrence of AF/atrial tachycardia (AT) following pulmonary vein ablation (PVA). MethodsFor the first 2months after PVA, 274 patients (age 6210years; 66% male) were individually scheduled for concomitant treatment with beta-adrenergic blocking agents (BB) or AAD therapy. Primary endpoint of this study was a composite of (1) AF/AT lasting more than 30seconds; (2) symptomatic AF/AT recurrence requiring intervention; or (3) intolerance to the antiarrhythmic agent given. Univariate and multivariate analysis was performed to evaluate predictors for successful AAD therapy. ResultsEarly after PVA, patients were treated with BB (n=89), flecainide (n=99), sotalol (n=37), dronedarone (n=29), or amiodarone (n=115). Ninety-five patients received a combination of AAD therapy and BB. A total of 369 observation periods were analyzed.

No significant difference regarding freedom from AF/AT recurrence with regard to different drug therapies was observed (P=0.769).
