Driver Domains in Persistent Atrial Fibrillation
Michel Haïssaguerre,Mélèze Hocini,Arnaud Denis,Ashok J. Shah,Yuki Komatsu,Seigo Yamashita,Matthew Daly,Sana Amraoui,Stephan Zellerhoff,Marie-Quitterie Picat,Adam Quotb,Laurence Jesel,Han S. Lim,Sylvain Ploux,Pierre Bordachar,Guillaume Attuel,Valentin Meillet,Philippe Ritter,Nicolas Derval,Frederic Sacher,Olivier Bernus,Hubert Cochet,Pierre Jaïs,Rémi Dubois +23 more
TL;DR: Persistent AF in early months is maintained predominantly by drivers clustered in a few regions, most of them being unstable reentries.
Journal ArticleDOI
Elimination of Local Abnormal Ventricular Activities: A New End Point for Substrate Modification in Patients with Scar-Related Ventricular Tachycardia
Pierre Jaïs,Philippe Maury,Paul Khairy,Frederic Sacher,Isabelle Nault,Yuki Komatsu,Mélèze Hocini,Andrei Forclaz,Amir Jadidi,Rukshen Weerasooryia,Ashok J. Shah,Nicolas Derval,Hubert Cochet,Sébastien Knecht,Shinsuke Miyazaki,Nick Linton,Lena Rivard,Matthew Wright,Stephen B. Wilton,Daniel Scherr,Patrizio Pascale,Laurent Roten,Michala Pederson,Pierre Bordachar,François Laurent,Steven Kim,Philippe Ritter,Jacques Clémenty,Michel Haïssaguerre +28 more
TL;DR: Elimination of LAVAs is feasible and safe and is associated with superior survival free from recurrent VT, and can be identified in most patients with scar-related VT.
Journal ArticleDOI
Five-Year Outcome of Catheter Ablation of Persistent Atrial Fibrillation Using Termination of Atrial Fibrillation as a Procedural Endpoint
Daniel Scherr,Paul Khairy,Shinsuke Miyazaki,Valerie Aurillac-Lavignolle,Patrizio Pascale,Stephen B. Wilton,Khaled Ramoul,Yuki Komatsu,Laurent Roten,Amir Jadidi,Nick Linton,Michala Pedersen,Matthew Daly,Mark D O'Neill,Sébastien Knecht,Rukshen Weerasooriya,Thomas Rostock,Martin Manninger,Hubert Cochet,Ashok J. Shah,Sunthareth Yeim,Arnaud Denis,Nicolas Derval,Mélèze Hocini,Frederic Sacher,Michel Haïssaguerre,Pierre Jaïs +26 more
TL;DR: In patients with persistent AF, an ablation strategy aiming at AF termination is associated with freedom from arrhythmia recurrence in the majority of patients over a 5-year follow-up period.
Journal ArticleDOI
Inverse relationship between fractionated electrograms and atrial fibrosis in persistent atrial fibrillation: combined magnetic resonance imaging and high-density mapping.
Amir Jadidi,Hubert Cochet,Ashok J. Shah,Steven Kim,Edward Duncan,Shinsuke Miyazaki,Maxime Sermesant,Heiko Lehrmann,Matthieu Lederlin,Nick Linton,Andrei Forclaz,Isabelle Nault,Lena Rivard,Matthew Wright,Xingpeng Liu,Daniel Scherr,Stephen B. Wilton,Laurent Roten,Patrizio Pascale,Nicolas Derval,Frederic Sacher,Sébastien Knecht,Cornelius Keyl,Mélèze Hocini,Michel Montaudon,François Laurent,Michel Haïssaguerre,Pierre Jaïs +27 more
TL;DR: Atrial fibrosis as defined by DE MRI is associated with slower and more organized electrical activity but with lower voltage than healthy atrial areas, important when choosing the ablation strategy in persistent AF.
Journal ArticleDOI
Noninvasive Electrocardiographic Mapping to Improve Patient Selection for Cardiac Resynchronization Therapy: Beyond QRS Duration and Left Bundle Branch Block Morphology
Sylvain Ploux,Joost Lumens,Zachary I. Whinnett,Michel Montaudon,Maria Strom,Charu Ramanathan,Nicolas Derval,Adlane Zemmoura,Arnaud Denis,Maxime De Guillebon,Ashok J. Shah,Mélèze Hocini,Pierre Jaïs,Philippe Ritter,Michel Haïssaguerre,Bruce L. Wilkoff,Pierre Bordachar +16 more
TL;DR: Electrocardiographic maps revealed homogeneous patterns of activation and consistently greater VEU and LV total activation time (LVTAT) in patients with LBBB compared with heterogeneous activation sequences and shorter V EU and LVTAT in NICD patients.
