Long-term outcomes after low power, slower movement versus high power, faster movement Irrigated-Tip Catheter Ablation for atrial fibrillation.
Heart rhythm, 2019Co-Authors: T. Jared Bunch, Heidi T May, Tami L. Bair, Brian G. Crandall, Michael J. Cutler, Charles Mallender, J. Peter Weiss, Jeffrey S. Osborn, John D. DayAbstract:Background High power, shorter duration (HPSD) Ablation strategies have been advocated to increase efficacy and minimize posterior wall deep tissue thermal injury during atrial fibrillation (AF) Ablation. Objective The purpose of this study was to determine the long-term outcomes of arrhythmia-free survival from AF and atrial flutter (AFL) between HPSD and low power, longer duration (LPLD) Ablation strategies. Methods Of a total of 1333 first time AF Ablation procedures with 3 years of follow-up, propensity-matched populations for baseline risk factors were created, comprising 402 patients treated with LPLD Ablation (30 W for 5 seconds: posterior wall; 30 W for 10–20 seconds: anterior wall) and 402 patients treated with HPSD Ablation (50 W for 2–3 seconds: posterior wall; 50 W for 5–15 seconds: anterior wall). AF/AFL outcomes after a 90-day blanking period were assessed. Results HPSD Ablation was associated with shorter procedure and fluoroscopy times (P Conclusion Long-term freedom from AF rates were not significantly different between both approaches. An HPSD Ablation strategy compared with an LPLD approach was associated with an increased risk of AFL and need for repeat Ablation but with lowered procedure times.

A Comparison of Remote Magnetic Irrigated Tip Ablation versus Manual Catheter Irrigated Tip Catheter Ablation With and Without Force Sensing Feedback.
Journal of Cardiovascular Electrophysiology, 2016Co-Authors: J. Peter Weiss, Heidi T May, Tami L. Bair, Brian G. Crandall, Michael J. Cutler, Charles Mallender, Jeffrey S. Osborn, John D. Day, T. Jared BunchAbstract:Comparison of Remote Magnetic Irrigated Tip Background Remote magnetic navigation (RMN) and contact force (CF) sensing technologies have been utilized in an effort to improve safety and efficacy of Catheter Ablation. A comparative analysis of the relative short- and long-term outcomes of AF patients has not been performed. As such, we comparatively evaluated the safety and efficacy of these technologies. Methods A total of 627 patients who underwent Catheter Ablation with either a manual irrigated tip Catheter: (312, 49.8%) or by RMN: (315, 50.2%) were included in this single-center cohort study. Patients treated with CF (59) were analyzed separately as well. One- and 3-year endpoints included death, HF hospitalization, stroke, TIA, and atrial flutter or AF recurrence. Results Age averaged 65.1 ± 10.7 years and 64.1% male. One- and 3-year endpoints of death, HF hospitalization, stroke, TIA, and atrial flutter or AF recurrence were statistically similar between manual and RMN treated groups. Fluoroscopy times were significantly lower in the RMN group compared to the manual Ablation group (8.47 ± 0.45 vs. 9.63 ± 4.06 minutes, P < 0.0001). CF guided patients had 1-year recurrence rate of AF/atrial flutter statistically identical to patients treated with RMN (36.8% vs. 38.6%; P = 1.00). Conclusion RMN results in outcomes similar to manual navigation. The addition of CF sensing Catheters did not improve relative procedural outcome or safety profile in comparison to RMN guided Ablation in this large observational study of AF Ablation.

The inferior vena cava: an exceptional source of atrial fibrillation.
Journal of cardiovascular electrophysiology, 2003Co-Authors: Christophe Scavée, Pierre Jaïs, Rukshen Weerasooriya, Michel HaïssaguerreAbstract:Mapping in a patient undergoing radiofrequency Ablation for drug-refractory paroxysmal atrial fibrillation in the setting of repetitive, monomorphic atrial ectopic beats with negative p waves in the inferior leads revealed an arrhythmogenic focus located in the posteromedial inferior vena cava (IVC) 1 cm below the right atrium to IVC junction. The focus was mapped using a Lasso Catheter with successful Irrigated-Tip Catheter Ablation at the site of earliest activity. This case demonstrates that, in rare cases, arrhythmogenic muscular sleeves can be found in the IVC and that the IVC can be electrically disconnected from the right atrium using radiofrequency energy.

Irrigated-Tip Catheter Ablation of pulmonary veins for treatment of atrial fibrillation.
Journal of cardiovascular electrophysiology, 2002Co-Authors: Laurent Macle, Pierre Jaïs, Dipen Shah, Mélèze Hocini, Jacques Clémenty, Rukshen Weerasooriya, Kee-joon Choi, Christophe Scavée, Florence Raybaud, Michel HaïssaguerreAbstract:Irrigated-Tip Catheter Ablation of PVs.Introduction: Catheter Ablation of pulmonary veins (PV) for treatment of atrial fibrillation (AF) is limited by the disparate requirements of sufficient energy delivery to achieve PV isolation while avoiding PV stenosis. The aim of the present study was to evaluate the safety and efficacy of using an Irrigated-Tip Catheter for systematic isolation of PV. Methods and Results: The study population consisted of 136 consecutive patients (109 men, mean age 52 ± 10 years) with symptomatic, drug-refractory paroxysmal (122) or persistent (14) AF. Cavotricuspid isthmus Ablation and systematic radiofrequency isolation of all four PVs (guided by a circumferential mapping Catheter) was performed in all patients with a protocol using an Irrigated-Tip Catheter. PV diameter was assessed by selective angiography. The electrophysiologic endpoint of PV isolation was achieved in 100% of patients. Bidirectional cavotricuspid isthmus block was achieved in 99% of patients. Moderate PV stenosis (50% narrowing) was observed in one patient (0.7%) without clinical consequence. No other complications were observed. ReAblation procedures were required in 67 patients (49%). After a mean follow-up of 8.8 ± 5.3 months, 81% of patients were free of AF clinical recurrence, including 66% not taking any antiarrhythmic drugs. Conclusion: Systematic radiofrequency Ablation of PV using an Irrigated-Tip Catheter in patients with atrial fibrillation allows complete isolation of all four PVs with a very low incidence of stenosis.

Efficacy and Safety of an Irrigated-Tip Catheter for the Ablation of Accessory Pathways Resistant to Conventional Radiofrequency Ablation
Circulation, 2000Co-Authors: Teiichi Yamane, Pierre Jaïs, Dipen Shah, Mélèze Hocini, Jacques Clémenty, Jing Tian Peng, Isabel Deisenhofer, Michel HaïssaguerreAbstract:Radiofrequency Catheter Ablation of accessory pathways (APs) is very effective in all but a minority of patients. We examined the usefulness and safety of Irrigated-Tip Catheters in treating patients with APs resistant to conventional Catheter Ablation. Among 314 APs in 301 consecutive patients, conventional Ablation failed to eliminate AP conduction in 18 APs in 18 patients (5.7%), 6 of which were located in the left free wall, 5 in the middle/posterior-septal space, and 7 inside the coronary sinus (CS) or its tributaries. Irrigated-Tip Catheter Ablation was subsequently performed with temperature control mode (target temperature, 50 degrees C), a moderate saline flow rate (17 mL/min), and a power limit of 50 W (outside CS) or 20 to 30 W (inside CS) at previously resistant sites. Seventeen of the 18 resistant APs (94%) were successfully ablated with a median of 3 applications using Irrigated-Tip Catheters. A significant increase in power delivery was achieved (20.3+/-11.5 versus 36.5+/-8.2 W; P:<0.01) with Irrigated-Tip Catheters, irrespective of the AP location, particularly inside the CS or its tributaries. No serious complications occurred. Irrigated-Tip Catheter Ablation is safe and effective in eliminating AP conduction resistant to conventional Catheters, irrespective of the location.

Successful Irrigated-Tip Catheter Ablation of Atrial Flutter Resistant to Conventional Radiofrequency Ablation
Circulation, 1998Co-Authors: Pierre Jaïs, Michel Haïssaguerre, Dipen Shah, A. Takahashi, Mélèze Hocini, Thomas Lavergne, Stephane Lafitte, Alain Le Mouroux, B Fischer, Jacques ClémentyAbstract:Catheter Ablation of typical right atrial flutter is now widely performed. The best end point has been demonstrated to be bidirectional isthmus block. We investigated the use of Irrigated-Tip Catheters in a small subset of patients who failed isthmus Ablation with conventional radiofrequency (RF) Ablation. Of 170 patients referred for Ablation of common atrial flutter, conventional Ablation of the cavotricuspid isthmus with >21 applications failed to create a bidirectional block in 13 (7.6%). An Irrigated-Tip Catheter Ablation was performed on identified gaps in the Ablation line according to a protocol found to be safe in animals: a moderate flow rate of 17 mL/min and temperature-controlled (target, 50 degrees C) RF delivery with a power limit of 50 W. Bidirectional isthmus block was achieved in 12 patients by use of a mean delivered power of 40+/-6 W with a single application in 6 patients and 2 to 6 applications in the other 6. No side effects occurred during or after the procedure. Irrigated-Tip Catheter Ablation is safe and effective for achieving cavotricuspid isthmus block when conventional RF energy has failed.
