Ventricular arrhythmias (VA), like premature ventricular contractions (PVC) and ventricular tachycardia (VT) in patients without structural heart disease (idiopathic VA), mainly arise from the right and left ventricular outflow tracts (RVOT/LVOT). The prognosis for OT VA is generally good in the majority of patients, but there is potential for developing dilated cardiomyopathies from the high burden of VA, as well as a certain risk for sudden cardiac death because of fast monomorphic VT or polymorphic VT triggered by short-coupling PVC. Radiofrequency catheter ablation (RFCA) has evolved into a widely accepted treatment strategy for patients suffering from VAs. A detailed knowledge of surface ECGs and complex cardiac anatomy, especially within the ventricular OTs, is essential for the understanding of cardiac OT-VAs and highly related to safe and successful RFCA procedures. This review article focuses on RFCA of idiopathic VA arising from the cardiac OT as well as adjacent regions and will illustrate recent insights and technical issues. (Circ J 2016; 80: 1073–1086)

Objective: The effects of treatment methods for ruptured aneurysms on the incidence of vasospasm and normal pressure hydrocephalus (NPH) following subarachnoid hemorrhage (SAH) are controversial. We retrospectively examined the Nagasaki SAH registry data, and the complication rates of symptomatic vasospasm and NPH were analyzed based on the treatment methods.Materials and Methods: Between January 2015 and December 2017, 800 SAH patients were registered from 18 hospitals, and their age, sex, World Federation of Neurological Societies (WFNS) grade, Fisher group, size and location of cerebral aneurysms, treatment methods, incidence of symptomatic vasospasm and shunt-dependent hydrocephalus, and prognosis (discharge or 3 months later) were retrospectively analyzed. The effects of treatment methods for the ruptured aneurysm on the incidence of symptomatic vasospasm and shunt-dependent hydrocephalus were then statistically analyzed.Results: The mean age was 66.2 years old. There were 245 (30.6%) male patients and 555 (69.3%) female patients. Cerebral aneurysms were identified in 708 patients (87.5%) and surgical treatments were performed for 620. Neck clipping was employed in 416 patients (67.1%) and coil embolization was employed in 180 (29.0%). Symptomatic vasospasm developed in 118 (28.4%) in the clipping group and 30 (16.7%) in the coiling group (P = 0.0024). NPH developed in 148 (35.6%) in the clipping group and 42 (23.3%) in the coiling group (P = 0.0032). Vasospasm was listed as a major factor for an unfavorable outcome in 23 patients (8.9%) and as a minor factor in 33 (13.3%). NPH was listed as a major factor for an unfavorable outcome in 19 patients (3.5%) and as a minor factor in 46 (18.5%).Conclusions: The multicenter registry study demonstrated lower incidences of both symptomatic vasospasms and NPH in the coiling group than in the clipping group. This superiority may result in better outcomes in the coiling group.

本稿は、瀬戸内国際芸術祭2013 春の部(2013年3月20日[春分の日]~4月21日[日])の一環として参加した「沙弥島アートプロジェクト by 神戸芸術工科大学」で行われた全ての活動について、成果物の画像を交えながらその内容を述べたものである。成果物として挙げられるのは、次の4つ、①香川県坂出市沙弥島内3カ所(西ノ浜、ナカンダ浜、旧沙弥小中学校)を舞台にした本学の教員(助手・実習助手含む)6名による作品展示・建築作品の公開、②準備期間中に行った地元の子供・親子を対象にしたワークショップ、③会期中に行った一般客及び地元住人を対象にしたイベント、④大学院の選択科目のひとつである大学院総合プロジェクト「沙弥島アートプロジェクト」において、担当教員の指導のもと、学生が行ったポスターや周辺地図などの印刷物およびスタッフ用パーカーなどのグッズ企画・制作である。This report assesses all the activities carried out in 'Shamijima Art Project by Kobe Design University' which was held as a part of Setouchi Triennale 2013 Spring term (20th March and 21st April 2013), together with the images of the project outcomes. The following four types of work have been completed in the project; ① Works of art and architecture created by six teachers of KDU(including assistants and a research assistant) in three different venues (Nishinohama Beach, Nakandahama Beach and Fomer-Shami Elementary and Junior High School), ②Workshops for the local people held in the preparation period, ③ Events for both the local and general visitors during the Triennale period, and ④ Poster, map and other graphic design works and goods productions such as staff costume created by students under the supervision in the one of the Kobe Design University graduate school's optional subjects which is also called 'Shamijima Art Project'.
