    • Antithrombotic therapy after acute ischemic stroke in patients with atrial fibrillation 

      McGrath, Emer R.; Kapral, Moira K.; Fang, Jiming; Eikelboom, John W.; ó Conghaile, Aengus; Canavan, Michelle; O’Donnell, Martin J. (Ovid Technologies (Wolters Kluwer Health), 2014-11-06)
      Background and Purpose-For patients with atrial fibrillation and ischemic stroke (IS), current guidelines recommend oral anticoagulation (OAC) alone for secondary prevention of IS. In a large prospective cohort of patients ...

    • Cardioneuroablation using epicardial pulsed field ablation for the treatment of atrial fibrillation 

      O’Brien, Barry; Reilly, John; Coffey, Ken; González-Suárez, Ana; Quinlan, Leo; van Zyl, Martin (MDPI, 2023-05-29)
      Atrial fibrillation (AF) is the most common cardiac arrhythmia affecting millions of people worldwide. The cardiac autonomic nervous system (ANS) is widely recognized as playing a key role in both the initiation and ...

    • Comparing mortality in patients with atrial fibrillation who are receiving a direct-acting oral anticoagulant or warfarin: a meta-analysis of randomized trials 

      Liew, A.; O'Donnell, M.; Douketis, J. (Wiley-Blackwell, 2014-07-25)
      BackgroundIn patients with non-valvular atrial fibrillation (AF), direct-acting oral anticoagulants (DOACs) are at least non-inferior to warfarin for the prevention of stroke and systemic embolism. The main objective of ...

    • Embolic strokes of undetermined source: prevalence and patient features in the esus global registry 

      Perera, Kanjana S; Vanassche, Thomas; Bosch, Jackie; Giruparajah, Mohana; Swaminathan, Balakumar; Mattina, Katie R; Berkowitz, Scott D; Arauz, Antonio; O’Donnell, Martin J; Ameriso, Sebastian F; Hankey, Graeme J; Yoon, Byung-Woo; Lavallee, Philippa; Cunha, Luis; Shamalov, Nikolay; Brouns, Raf; Gagliardi, Rubens J; Kasner, Scott E; Pieroni, Alessio; Vermehren, Philipp; Kitagawa, Kazuo; Wang, Yongjun; Muir, Keith; Coutinho, Jonathan; Vastagh, Ildiko; Connolly, Stuart J; Hart, Robert G (SAGE Publications, 2016-04-11)
      Background: Recent evidence supports that most non-lacunar cryptogenic strokes are embolic. Accordingly, these strokes have been designated as embolic strokes of undetermined source (ESUS). Aims: We undertook an international ...

    • Epicardial pulsed field ablation of ganglionated plexi: Computational and pre-clinical evaluation of a bipolar sub-xiphoid catheter for the treatment of atrial fibrillation 

      O’Brien, Barry; Reilly, John; Coffey, Ken; González-Suárez, Ana; Buchta, Piotr; Buszman, Piotr P.; Lukasik, Karolina; Tri, Jason; van Zyl, Martin; Asirvatham, Samuel (MDPI, 2023-12-24)
      Epicardial pulsed field ablation (PFA) of ganglionated plexi (GPs) is being explored as a potential treatment for atrial fibrillation. Initial work using open-chest access with a monopolar ablation device has been completed. ...

    • Global survey of the frequency of atrial fibrillation–associated stroke 

      Perera, Kanjana S.; Vanassche, Thomas; Bosch, Jackie; Swaminathan, Balakumar; Mundl, Hardi; Giruparajah, Mohana; Barboza, Miguel A.; O’Donnell, Martin J.; Gomez-Schneider, Maia; Hankey, Graeme J.; Yoon, Byung-Woo; Roxas, Artemio; Lavallee, Philippa; Sargento-Freitas, Joao; Shamalov, Nikolay; Brouns, Raf; Gagliardi, Rubens J.; Kasner, Scott E.; Pieroni, Alessio; Vermehren, Philipp; Kitagawa, Kazuo; Wang, Yongjun; Muir, Keith; Coutinho, Jonathan M.; Connolly, Stuart J.; Hart, Robert G. (Ovid Technologies (Wolters Kluwer Health), 2016-08-09)
      Background and Purpose-Atrial fibrillation (AF) is increasingly recognized as the single most important cause of disabling ischemic stroke in the elderly. We undertook an international survey to characterize the frequency ...

    • In vitro model development for pulsed-field ablation treatment of atrial fibrillation 

      Baena Montes, Jara Maria (NUI Galway, 2024-04-15)
      Atrial fibrillation is the most common type of cardiac arrhythmias in humans, mostly based on hyperexcitation of specific areas in the atrium that results in dyssynchronous atrial contraction, leading to severe ...

    • Which risk factors are more associated with ischemic stroke than intracerebral hemorrhage in patients with atrial fibrillation? 

      McGrath, E. R.; Kapral, M. K.; Fang, J.; Eikelboom, J. W.; Conghaile, A. o.; Canavan, M.; O'Donnell, M. J.; , (Ovid Technologies (Wolters Kluwer Health), 2012-05-22)
      Background and Purpose-The decision to prescribe oral anticoagulant therapy in patients with atrial fibrillation is based on an assessment of the competing risks of ischemic stroke and major bleeding, of which intracerebral ...
