AIMS:Anomalous origin of the coronary artery (AOCA) with an inter-arterial course (IAC) between the great vessels poses a risk for a life-threatening cardiovascular event. We assessed, in a registry-based study, the clinical features, treatment strategies, and prognoses of life-threatening cardiovascular events ensuant to AOCA. METHODS AND RESULTS:Included were 65 AOCA ... Read more >>

Successful Ablation of Atrial Tachycardia Originating from Inside the Single Atrium and Conduit After a Fontan Operation.

Hitoshi Mori, Naokata Sumitomo, Shota Muraji, Tomohiko Imamura, Noriyuki Iwashita, Toshiki Kobayashi,

An 18-year-old male who had a past medical history of an intracardiac total cavopulmonary connection (TCPC) operation was referred to our hospital for radiofrequency catheter ablation (RFCA) of supraventricular tachycardia (SVT). Two types of SVTs were induced, and 3-dimensional (3D) maps were created using an ultra-high-density 3-dimensional mapping system (Rhythmia). ... Read more >>

[EFFECT OF INSPIRATORY FLOW ON BREATH SOUND ANALYSIS IN CHILDREN WITH ASTHMA].

Takanori Kagawa, Tomohiko Imamura, Mayumi Enseki, Hideyuki Tabata, Hiroyuki Furuya, Fumio Niimura, Hiroyuki Mochizuki,

BACKGROUND:In order to determine the optimal breathing method for childhood lung sound analyses, it is important to study the effect of airflow on the parameters of lung sounds. METHODS:Sixty-one well-controlled children with atopic asthma (median; 12 years) participated. After confirming that there was no wheezing or respiratory symptoms, the lung ... Read more >>

Cardiopulmonary failure as a result of brainstem encephalitis caused by enterovirus D68.

Naoki Yogo, Tomohiko Imamura, Yuichiro Muto, Katsuki Hirai,

Enterovirus D68 (EV-D68) causes respiratory illnesses such as pneumonia, and has been reported to cause acute flaccid myelitis. Enterovirus A71 (EV-A71) is known to cause cardiopulmonary failure due to brainstem encephalitis, but there have been few reports of these conditions being associated with EV-D68. Outbreaks of EV-D68 infection have occurred ... Read more >>

Improvement in Dyssynchrony with Pharmacological Ablation of Right-Sided Accessory Pathway-Induced Cardiomyopathy in Infants.

Mai Sekine, Satoshi Masutani, Tomohiko Imamura, Yoichi Iwamoto, Shota Muraji, Shigeki Yoshiba, Hirotaka Ishido, Naokata Sumitomo,

Right-sided accessary pathways in patients with Wolff-Parkinson-White (WPW) syndrome may cause cardiac dyssynchrony and dilated cardiomyopathy, with a characteristic septal shape, irrespective of any supraventricular tachycardia episodes. We report on two infants (13 and 5 months), whose right-sided accessary pathway-induced dilated cardiomyopathy was successfully treated by flecainide for the first ... Read more >>

Usefulness of Red Blood Cell Distribution Width in the Assessment of Hemodynamics After Tetralogy of Fallot Repair.

Takuro Kojima, Tomohiko Imamura, Yousuke Osada, Shouta Muraji, Marie Nakano, Takayuki Oyanagi, Shigeki Yoshiba, Toshiki Kobayashi, Naokata Sumitomo,

BACKGROUND:There are no reports on the effect of red blood cell distribution width (RDW) in surgical repair of tetralogy of Fallot (ToF). Methods and Results: A total of 50 patients who underwent cardiac catheterization after surgical repair of ToF were retrospectively assessed. RDW was positively correlated with the ratio of right ventricular ... Read more >>

The necessity of implantable cardioverter defibrillators in patients with Kearns-Sayre syndrome - systematic review of the articles.

Tomohiko Imamura, Naokata Sumitomo, Shota Muraji, Hitoshi Mori, Yousuke Osada, Takayuki Oyanagi, Takuro Kojima, Shigeki Yoshiba, Toshiki Kobayashi, Katsushige Ono,

The most common cardiac feature of Kearns-Sayre syndrome (KSS) is atrioventricular block (AVB), and pacemaker implantations (PMIs) are recommended for KSS patients with advanced AVB. However, some KSS patients develop fatal arrhythmias such as polymorphic ventricular tachycardia (PMVT) and ventricular fibrillation (VF) and die suddenly even after PMIs. We report ... Read more >>
