    Abstract Aims: In the SCALAF trial, catheter-based pulmonary vein isolation (PVI) was as effective in long-term prevention of atrial fibrillation (AF) as minimally invasive thoracoscopic PVI and left atrial appendage ligation (MIPI). Catheter ablation (CA) resulted in significantly less major complications as compare to MIPI. We report quality of life (QOL) outcome in these patients.
    Methods: In this study, 52 patients with symptomatic paroxysmal or early persistent AF were randomized to either MIPI or CA. QOL was assessed at baseline, 3, 6, and 12 months follow-up using the SF-36 Health Survey Questionnaire. AF-related symptoms were quantified at each follow-up visit using the European Heart Rhythm Association (EHRA) score.
    Results: Median age was 57 years and 78% was male. Paroxysmal AF was present in 74%. At 3 months follow-up, physical role limitations (88.2 ± 29.5; versus 40.9 ± 44.0; P = 0.001, respectively) and bodily pain scores (95.5 ± 8.7; versus 76.0 ± 27.8; P = 0.021, respectively) were significantly higher after CA compared to MIPI, indicating less limitation in daily activity caused by physical problems and less pain after CA than after MIPI. AF symptoms assessed by the EHRA scores improved significantly at 3, 6, 12, and 24 months compared to baseline in both treatment groups (P < 0.001), with no significant differences between treatment groups.
    Conclusions: CA and MIPI ablation of AF both resulted in an improvement in several QOL measurements, although CA resulted in significantly less physical problems and bodily pain 3 months after treatment compared to MIPI.

    Abstract Background: Current guidelines recommend both percutaneous catheter ablation (CA) and surgical ablation in the treatment of atrial fibrillation, with different levels of evidence. No direct comparison has been made between minimally invasive thoracoscopic pulmonary vein isolation with left atrial appendage ligation (surgical MIPI) versus percutaneous CA comprising of pulmonary vein isolation as primary treatment of atrial fibrillation. We, therefore, conducted a randomized controlled trial comparing the safety and efficacy of these 2 treatment modalities.
    Methods: Eighty patients were enrolled in the study and underwent implantable loop recorder implantation. Twenty-eight patients did not reach randomization criteria. A total of 52 patients with symptomatic paroxysmal or early persistent atrial fibrillation were randomized, 26 to CA and 26 to surgical MIPI. The primary end point was defined as freedom of atrial tachyarrhythmias, without the use of antiarrhythmic drugs. The safety end point was freedom of complications.
    Results: Median age was 57 years (range, 37-75), and 78% were men. Paroxysmal atrial fibrillation was present in 74%. Follow-up duration was ≥2 years in all patients. CA was noninferior to MIPI in terms of single-procedure arrhythmia-free survival after 2 years of follow-up (56.0% versus 29.2%; HR, 0.56; 95% CI, 0.26-1.20; log-rank P=0.059). Procedure-related major adverse events occurred significantly more often in MIPI than CA (20.8% versus 0%; P=0.029).
    Conclusions: Percutaneous pulmonary vein isolation was noninferior to MIPI in terms of efficacy and resulted in less complications.

    Abstract Background: The electrophysiologic effects of acute atrial dilatation and dedilatation in humans with chronic atrial fibrillation remains to be elucidated.
    Objective: To study the electrophysiological effects of acute atrial dedilatation and subsequent dilatation in patients with long-standing persistent atrial fibrillation (AF) with structural heart disease undergoing elective cardiac surgery.
    Methods: Nine patients were studied. Mean age was 71 ± 10 years, and left ventricular ejection was 46% ± 6%. Patients had at least moderate mitral valve regurgitation and dilated atria. After sternotomy and during extracorporal circulation, mapping was performed on the beating heart with 2 multielectrode arrays (60 electrodes each, interelectrode distance 1.5 mm) positioned on the lateral wall of the right atrium (RA) and left atrium (LA). Atrial pressure and size were altered by modifying extracorporal circulation. AF electrograms were recorded at baseline after dedilation and after dilatation of the atria afterward.
    Results: At baseline, the median AF cycle length (mAFCL) was 184 ± 27 ms in the RA and 180 ± 17 ms in the LA. After dedilatation, the mAFCL shortened significantly to 168 ± 13 ms in the RA and to 168 ± 20 ms in the LA. Dilatation lengthened mAFCL significantly to 189 ± 17 ms in the RA and to 185 ± 23 ms in the LA. Conduction block (CB) at baseline was 14.3% ± 3.6% in the RA and 17.3% ± 5.5% in the LA. CB decreased significantly with dedilatation to 7.4% ± 2.9% in the RA and to 7.9% ± 6.3% in the LA. CB increased significantly with dilatation afterward to 15.0% ± 8.3% in the RA and to 18.5% ± 16.0% in the LA.
    Conclusions: Acute dedilatation of the atria in patients with long-standing persistent AF causes a decrease in the mAFCL in both atria. Subsequent dilatation increased the mAFCL. The amount of CB decreased with dedilatation and increased with dilatation afterward in both atria.

    Abstract We describe a technical challenge in a 17-year-old patient with incessant epicardial focal ventricular arrhythmia and diminished LV function. Failure of ablation at the earliest activated endocardial site during ectopy suggested an epicardial origin, which was supported by specific electrocardiographic criteria. Epicardial ablation was not possible due to the localization of the origin of the ventricular tachycardia adjacent to the phrenic nerve. Minimal invasive surgical multielectrode high-density epicardial mapping was performed to localize the arrhythmia focus. Epicardial surgical RF ablation resulted in the termination of ventricular ectopy. After 2 years, the patient is still free from arrhythmias.

    Abstract Studies have shown that continuous rhythm monitoring enables the detection of significantly more atrial fibrillation (AF) episodes than routine follow-up of patients, i.e. based on perception of symptoms or on 24-48 h Holter monitoring. The positive outcome of radiofrequency ablation (RFA) may be easily overestimated, especially in patients with paroxysmal AF. Thirty-three consecutive patients, aged 59.4+/-8.9 years (range 38-75 years) participated in this study. All patients had documented AF episodes with an AF duration of 9.4+/-7.1 years (range 1.5-25 years). A new monitoring device, the AF-Alarm was used to more accurately assess the outcome after surgical isolation of pulmonary veins. The AF-Alarm was applied for a duration of 128+/-42.5 h (range 49-191 h) during a period of 8-15 days. The success rate was 87% based on serial electrocardiograms (ECGs) and 24-48 h Holter monitoring during regular outpatient visits. Combination of ECG, Holter and AF-Alarm data yielded a significantly lower success rate, i.e. at the latest follow-up 69% of the patients were free from AF after surgical ablation (P<0.05). Furthermore, the AF-Alarm device demonstrated a dissociation between symptoms and atrial arrhythmic events and confirmed the occurrence of asymptomatic AF episodes. The most important limitation of the AF-Alarm device was noise detection with oversensing and inappropriate detection of non-existing AF episodes in 9% of patients. Long-term follow-up of the patients seems to be essential as success rates of the initial ablation procedure might vary over time. External recorders like the AF-Alarm may be used as an additional tool to document symptomatic and asymptomatic episodes of atrial arrhythmias in the outpatient setting.
