Reentrant atrial tachycardia after catheter ablation of coronary sinus accessory pathway
Koichi Watanabe,Hidehiro Iwakawa,Ken Terata,Hiroyuki Watanabe +3 more
Abstract: Some patients require radiofrequency catheter ablation (RFCA) within the coronary sinus (CS) to eliminate conduction through accessory pathways (APs). A 23-year-old man was diagnosed with atrioventricular reentrant tachycardia (AVRT) utilizing a left-sided AP as the retrograde limb and was successfully treated by RFCA within the CS. Following the RFCA, another form of narrow QRS complex tachycardia was observed, and an electrophysiology study revealed the tachycardia as reentrant atrial tachycardia (AT) involving the CS. RFCA within the CS successfully terminated the tachycardia. This is the first case of iatrogenic reentrant AT secondary to RFCA for AVRT. Learning objective Radiofrequency catheter ablation (RFCA) is the standard treatment for atrioventricular reentrant tachycardia (AVRT) caused by accessory pathways. This case highlights that patients with AVRT who have undergone extensive RF applications may develop recurrent reentrant atrial tachycardia. Operators need to be aware that extensive RF applications can generate arrhythmogenic substrates, even in patients with AVRT.

Masao Daimon,Hiroyuki Watanabe,Yukio Abe,Kumiko Hirata,Takeshi Hozumi,Katsuhisa Ishii,Hiroshi Ito,Katsuomi Iwakura,Chisato Izumi,Masunori Matsuzaki,Shinichi Minagoe,Haruhiko Abe,Kazuya Murata,Satoshi Nakatani,Kazuaki Negishi,Ken Yoshida,Kazuaki Tanabe,Nobuhiro Tanaka,Kotaro Tokai,Junichi Yoshikawa +19 more
TL;DR: Normal values of echocardiographic measurements in a large Japanese population are reported for the first time; several systolic and diastolic parameters varied with age, whereas indexed LA volume did not vary with age.
Impact of obesity on plasma B-type natriuretic peptide levels in Japanese community-based subjects
Megumi Koizumi,Hiroyuki Watanabe,Yoshihiro Kaneko,Kenji Iino,Masaru Ishida,Toshimitsu Kosaka,Yutaka Motohashi,Hiroshi Ito +7 more
TL;DR: Plasma BNP levels are inversely related with obesity, as measured by AC, in Japanese community-based subjects, and these effects were more prominent in men than in women.
Functional role of stromal interaction molecule 1 (STIM1) in vascular smooth muscle cells.
Yoichiro Takahashi,Hiroyuki Watanabe,Manabu Murakami,Kyoichi Ono,Yoshiko Munehisa,Takashi Koyama,Kiyoshi Nobori,Toshihiko Iijima,Hiroshi Ito +8 more
TL;DR: It is suggested that STIM1 is an essential component of SOCE and that it is involved in VSMC proliferation.
Loss of Apelin Augments Angiotensin II-Induced Cardiac Dysfunction and Pathological Remodeling.
Teruki Sato,Ayumi Kadowaki,Takashi Suzuki,Hiroshi Ito,Hiroyuki Watanabe,Yumiko Imai,Keiji Kuba +6 more
TL;DR: It is shown that the detrimental effects of angiotensin II (Ang II) were exacerbated in the hearts of aged apelin-gene-deficient mice, and endogenous apelin plays a crucial role in suppressing Ang II-induced cardiac dysfunction and pathological remodeling.
