Multiple arrhythmogenic foci associated with the development of perpetuation of atrial fibrillation.
Toshiya Kurotobi,Katsuomi Iwakura,Koichi Inoue,Ryusuke Kimura,Atsunori Okamura,Yasushi Koyama,Yuko Tosyoshima,Norihisa Ito,Kenshi Fujii +8 more
TL;DR: Multiple foci were likely to be involved in the development of persistent AF, however, if AF persisted for >12 months, they may not have had a significant effect on the AF perpetuation.

Myocardial contrast echocardiography with a new calibration method can estimate myocardial viabilityin patients with myocardial infarction
Akio Yano,Hiroshi Ito,Katsuomi Iwakura,Ryusuke Kimura,Kouji Tanaka,Atsunori Okamura,Shigeo Kawano,Tohru Masuyama,Kenshi Fujii +8 more
TL;DR: Calibrated CI provides an estimate of persistently akinetic myocardium in patients with MI, and its color-coded mapping is comprehensive and identifies the spatial extent of MI.

Effect of elevated left ventricular diastolic filling pressure on the frequency of left atrial appendage thrombus in patients with nonvalvular atrial fibrillation.
Katsuomi Iwakura,Atsushi Okamura,Yasushi Koyama,Motoo Date,Yoshiharu Higuchi,Koichi Inoue,Ryusuke Kimura,Hiroyuki Nagai,Yuko Toyoshima,Makito Ozawa,Norihisa Ito,Masahiko Shibuya,Shigemiki Omiya,Takashi Takagi,Daisuke Morisawa,Kenshi Fujii +15 more
TL;DR: Increased diastolic filling pressure is associated with a higher rate of LAA thrombus in AF, partly through blood stasis or impaired LAA function, and increased quartile of E/e' was negatively associated with LAA flow velocity and positively with rate of SEC.

Signals through gp130 upregulate Wnt5a and contribute to cell adhesion in cardiac myocytes.
Yasushi Fujio,Takahisa Matsuda,Yuichi Oshima,Makiko Maeda,Tomomi Mohri,Takashi Ito,Tomoka Takatani,Mayo Hirata,Yoshikazu Nakaoka,Ryusuke Kimura,Tadamitsu Kishimoto,Junichi Azuma +11 more
TL;DR: It is demonstrated that the stimulation of gp130 with leukemia inhibitory factor (LIF) promoted cell adhesion in a cadherin‐dependent manner in cultured cardiomyocytes.

Solitary right ventricle metastasis by renal cell carcinoma.
Mitsuru Masaki,Tadashi Kuroda,Naoki Hosen,Hisao Hirota,Kazuo Terai,Yuichi Oshima,Yoshikazu Nakaoka,Shoko Sugiyama,Ryusuke Kimura,Satoshi Yoshihara,Manabu Kawakami,Norishige Iizuka,Yasuhiko Tomita,Hiroyasu Ogawa,Ichiro Kawase,Keiko Yamauchi-Takihara +15 more
TL;DR: This case highlights the need to consider an underlying neoplastic syndrome in patients presenting isolated right ventricle mass by echocardiography in patients presented with presyncope.
