  • New technologies in Atrial Fibrillation Ablation.
    Circulation, 2009
    Co-Authors: J. David Burkhardt, Andrea Natale
    Abstract:

    The treatment of Atrial Fibrillation has changed greatly in the past decade. Not long ago, the scientific community argued the benefits of a rate-control strategy versus a rhythm-control strategy.1 This argument was always hampered by the relative ineffectiveness of the antiarrhythmic medications used as rhythm-control agents. Ablation therapy for the treatment of Atrial Fibrillation has quickly evolved. Originally, Ablation was focused on finding triggers of Atrial Fibrillation in the pulmonary veins.2,3 Now, Ablation offers a potential curative strategy for patients with paroxysmal, persistent, or permanent Atrial Fibrillation. Recent data continue to show that Atrial Fibrillation Ablation is superior to the currently available antiarrhythmic medications in the maintenance of sinus rhythm, and the Food and Drug Administration has approved devices labeled for the Ablation of Atrial Fibrillation.4–6 It is estimated that >2 million people in the United States have Atrial Fibrillation.7 Although the number of Atrial Fibrillation Ablations continues to increase year after year, offering this therapy to all potential candidates is impossible because of several limitations.8,9 A finite number of fellows are being trained in programs that offer a great deal of experience in Atrial Fibrillation Ablation, and there is limited opportunity for practicing electrophysiologists to learn new techniques. Unlike supraventricular tachycardia Ablation, Atrial Fibrillation Ablation requires greater technical skill, significantly more lesions, and time. Like many other medical procedures, technological innovation is likely to be a contributing factor in making Atrial Fibrillation Ablation a more commonplace and widely practiced therapy. Navigating the complex anatomy of the left atrium is also difficult to master. Imaging technologies have been used to orient the operator to the anatomy and the location of the Ablation catheters in this anatomy. With fluoroscopy alone, it is difficult to determine anterior versus posterior orientation or the presence of the catheter in …

  • Real-world experience with Atrial Fibrillation Ablation: cause for concern
    European heart journal, 2014
    Co-Authors: Stuart J. Connolly
    Abstract:

    This editorial refers to ‘The Atrial Fibrillation Ablation Pilot Study: a European survey on methodology and results in catheter Ablation for Atrial Fibrillation’, by The European Heart Rhythm Association doi:10.1093/eurheartj/ehr114 Atrial Fibrillation (AF) Ablation has undergone a huge increase in popularity in the past few years. The effectiveness of this treatment is supported by several small randomized controlled trials in a number of different AF patient groups. Most of the trials show significant reductions in recurrence of AF compared with medical therapy. Atrial Fibrillation Ablation is now endorsed in international guidelines where it is considered first-line therapy for some patients. Consequently AF Ablation has now become a standard procedure at most medical centres in Western Europe and North America. It is supported by national and regional reimbursement bodies and is more and more widely used. It is appropriate to ask about the effects of this major change in practice on patient outcomes. Registries and cohort follow-up studies are the appropriate tools for addressing this question. Observational research studies are complementary to randomized trials, as they provide some insights into the effects of treatments as they are actually delivered in clinical practice, especially when these registries use robust methodologies. The best registries are population based, which avoids patient and centre selection biases. The Atrial Fibrillation Ablation Pilot Study, conducted by the European Heart Rhythm Association, is therefore a welcome addition to the literature reporting on the real world results of AF Ablation in Europe.1 The Atrial Fibrillation Ablation Pilot Study, planned as a precursor to a larger, more prolonged European observational study, was performed at 72 cardiology centres in 10 European countries, which were selected broadly to represent current European clinical practice. Sponsored financially by the European Heart Rhythm Association, National Cardiology Societies of each country agreed to participate and …

  • Mechanisms of Atrial tachyarrhythmias following surgical Atrial Fibrillation Ablation.
    Journal of cardiovascular electrophysiology, 2006
    Co-Authors: Anthony R. Magnano, Michael Argenziano, Jose Dizon, Deon W. Vigilance, Mathew R. Williams, Hilary A. Yegen, Kevin Rueter, Hasan Garan
    Abstract:

    Atrial Arrhythmias After Surgical AF Ablation. Introduction: Typical and atypical Atrial flutters (AFLs) and Atrial tachycardias (ATs) have been reported in patients with prior surgical Atrial Fibrillation Ablation. The underlying mechanisms for this group of Atrial tachyarrhythmias have not been well characterized and the efficacy of catheter Ablation in their treatment is unknown. Methods and Results: Twenty patients (6 females) with a surface ECG diagnosis of AFL or AT following surgical Atrial Fibrillation Ablation underwent 26 electrophysiology studies. Patients manifesting sustained, organized, and beat-by-beat reproducible Atrial electrical activity underwent complete right and left Atrial catheter mapping and catheter Ablation. One patient had no inducible tachyarrhythmia, while 5 patients had nonmappable arrhythmias. Nineteen of the 31 potentially mappable Atrial tachyarrhythmias were completely characterized in 14 patients. The underlying mechanisms were macro-reentrant left AFL (n = 9), focal left AT (n = 3), typical right AFL (n = 6), and atypical right AFL (n = 1). Of the 19 completely characterized Atrial arrhythmias, catheter Ablation was performed for 18, and the procedure was successful for 13 of these. After a mean follow-up of 15 ± 10 months, 15 of 20 patients (75%) were in sinus rhythm including 10 of 13 patients (77%) with AT/flutter Ablation. Ten patients, including 6 following Ablation, were maintaining sinus rhythm without antiarrhythmic medications. Conclusions: Patients with an ECG diagnosis of AFL or AT following surgical Atrial Fibrillation Ablation may have multiple tachycardia mechanisms with the right or left atrium as the site of origin. Many of these rhythms may resolve with further maturation of surgical Atrial Fibrillation Ablation (SAFA) lesions or be treatable with antiarrhythmic medication. However, persistent tachyarrhythmias can often be treated successfully with catheter mapping and Ablation.

  • Laser energy source in surgical Atrial Fibrillation Ablation: preclinical experience.

    Abstract:

    Purpose The purpose of this study was to evaluate diffusing tip laser energy in surgical Atrial Fibrillation Ablation using a canine model. This is the first report to describe the pathological and histological findings using a laser energy source. Description The surgical Atrial Fibrillation Ablation procedure was performed through a left atriotomy; the pulmonary veins were encircled in 16 dogs using a diode laser (980 nm) with a diffusing tip that permits linear Ablation perpendicular to the fiber direction. Lesion durations were 45 seconds with a power density of 3.8 or 4.5 W/cm. Six animals were allowed to survive 4 hours after the procedure, with the remainder sacrificed at 1 week (n = 1), 4 weeks (n = 3), and 6 weeks (n = 6). Electrophysiologic effectiveness was judged using unipolar or bipolar pacing from the pulmonary veins after attempting isolation. Hearts were harvested for histologic examination using standard trichrome staining. Evaluation All animals tolerated the procedure. The animals required an average of 5.6 ± 0.82 lesions to complete the procedure. All animals had confirmed isolation of the pulmonary veins as judged by unipolar or bipolar pacing, and this isolation persisted in those animals that were allowed to survive. Pathology revealed all lesions to be transmural with an average tissue thickness of 3.62 ± 1.50 mm (range, 0.95 mm to 7.06 mm). Conclusions Diffusing tip laser technology reproducibly makes rapid, transmural, and electrophysiologically effective Atrial lesions.
