Localized rotors and focal impulse sources within the left atrium in human atrial fibrillation: A phase analysis of contact basket catheter electrograms

Autor: Naoko Sasaki, MD, Yasuo Okumura, MD, PhD, Ichiro Watanabe, MD, PhD, Andrew Madry, PhD, Yuki Hamano, BE, Mizuki Nikaido, BE, Rikitake Kogawa, MD, Koichi Nagashima, MD, PhD, Keiko Takahashi, MD, Kazuki Iso, MD, Kimie Ohkubo, MD, PhD, Toshiko Nakai, MD, PhD, Atsushi Hirayama, MD, PhD

Publikováno v: Journal of Arrhythmia, Vol 32, Iss 2, Pp 141-144 (2016)

Background: Consistent detection of rotor(s) and/or focal impulse(s) of atrial fibrillation can using a 64-pole basket catheter remain unclear. Methods and results: Intracardiac left atrial electrograms were recorded, prior to ablation, in 20 patient

Publikováno v: Journal of Arrhythmia, Vol 31, Iss 6, Pp 352-358 (2015)

Background: Because obesity is an important risk factor for atrial fibrillation (AF), we conducted an animal study to examine the effect of a high-fat diet (HFD) on atrial properties and AF inducibility. Methods: Ten 8-week-old pigs (weight, 18–23

Journal of Arrhythmia

Background: Ablation targeting complex fractionated atrial electrograms (CFAEs) or high dominant frequency (DF) sites is generally effective for persistent atrial fibrillation (AF). CFAEs and/or high DF sites may exist in low-voltage regions, which t

Wavefront direction and cycle length affect left atrial electrogram amplitude

Autor: Kazuki Iso, Atsushi Hirayama, Masaru Arai, Ichiro Watanabe, Mizuki Nikaido, Keiko Takahashi, Ryuta Watanabe, Koichi Nagashima, Kimie Ohkubo, Rikitake Kogawa, Yasuo Okumura, Toshiko Nakai

Journal of Arrhythmia, Vol 33, Iss 4, Pp 269-274 (2017)

Background: The relationship between atrial electrogram (EGM) characteristics in atrial fibrillation (AF) and those in sinus rhythm (SR) are generally unknown. The activation rate and direction may affect EGM characteristics. We examined characterist

Anatomical proximity between ganglionated plexi and epicardial adipose tissue in the left atrium: implication for 3D reconstructed epicardial adipose tissue-based ablation

Autor: Atsushi Hirayama, Yasuo Okumura, Naoko Sasaki, Yuichi Hori, Shiro Nakahara, Rikitake Kogawa, Kazuki Iso, Kazumasa Sonoda, Toshiko Nakai, Sayaka Kurokawa, Ichiro Watanabe, Kimie Ohkubo, Koichi Nagashima, Mizuki Nikaido, Keiko Takahashi

Publikováno v: Journal of Interventional Cardiac Electrophysiology. 47:203-212

We sought to better understand the association between and clinical implications of ganglionated plexi (GPs), epicardial adipose tissue (EAT) in the left atrium (LA), and the initiation and maintenance of atrial fibrillation (AF). Three-dimensional (
