Journal ArticleDOI
Superior vena cava isolation by right pulmonary vein ablation.
TL;DR: A 77-year-old female patient with paroxysmal atrial fibrillation was referred for catheter ablation and two components of potentials were recorded at a circular mapping catheter placed in the antrum of RSPV.
Journal ArticleDOI
Association of the Clinical and Genetic Factors With Superior Vena Cava Arrhythmogenicity in Atrial Fibrillation.
Yusuke Ebana,Junichi Nitta,Yoshihide Takahashi,Shinsuke Miyazaki,Masahito Suzuki,Lian Liu,Kenzo Hirao,Eiichiro Kanda,Mitsuaki Isobe,Tetsushi Furukawa +9 more
TL;DR: It was found that SVC arrhythmogenicity was conditionally dependent on age, body mass index, and left ventricular ejection fraction, and this finding was confirmed in a meta-analysis using independent cohorts.
Journal ArticleDOI
Novel Dielectric Coagulometer Identifies Hypercoagulability in Patients with a High CHADS2 Score without Atrial Fibrillation.
Yuki Hasegawa,Satomi Hamada,Takuro Nishimura,Takeshi Sasaki,Yusuke Ebana,Mihoko Kawabata,Masahiko Goya,Mitsuaki Isobe,Takatoshi Koyama,Tetsushi Furukawa,Kenzo Hirao,Tetsuo Sasano +11 more
TL;DR: The derivative of the dielectric permittivity change after recalcification was calculated, and the end of acceleration time (EAT) was extracted as a novel index and detected the whole blood coagulability with a high sensitivity.
Journal ArticleDOI
Electrophysiology of a gap created on the canine atrium
TL;DR: Histological examination showed that the conduction properties through the gap depended mainly on its size, which was affected by the size of the gap, and may be evaluated by the duration and configuration of the local electrogram recorded from the gap.
Journal ArticleDOI
Reappraisal of the clinical implications of adenosine triphosphate in terms of the prediction of reconnection sites in cases with electrical isolation of the pulmonary veins
Kaoru Okishige,Hideshi Aoyagi,Kensuke Ihara,Shinsuke Iwai,Tomofumi Nakamura,Mitsumi Yamashita,Nobutaka Katoh,Tomoaki Hasegawa,Naohiko Kawaguchi,Takehiko Keida,Tetsuo Sasano,Kenzo Hirao +11 more
TL;DR: Dormant conduction induced by intravenous adenosine triphosphate after pulmonary vein (PV) isolation (PVI) could predict subsequent PV reconnection (RC) sites but a weak relationship was found.
