Early assessment of cardiac troponin I predicts the postoperative cardiac status and clinical course after congenital heart disease surgery.

Takuro Kojima, Koichi Toda, Takayuki Oyanagi, Shigeki Yoshiba, Toshiki Kobayashi, Naokata Sumitomo,

Cardiac troponin I (cTnI) is a regulatory protein with a high sensitivity and specificity for cardiac injury. Preoperative and postoperative elevations of cTnI are usually considered predictors of the mortality and morbidity. However, little is known about the relationship between the cTnI and postoperative course after the congenital heart disease ... 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 >>

Efficacy of catheter interventions in the early and very early postoperative period after CHD operation.

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

BACKGROUND:Catheter interventions for residual lesions in the early postoperative period after CHD operations are still not established as a reliable treatment option. METHODS:We retrospectively reviewed our institutional experience of cardiac catheterisations and catheter interventions performed in the early postoperative period. We classified our patients into two groups. The "hyper" acute ... Read more >>

Successful radiofrequency catheter ablation of life-threatening atrial tachycardia in an infant with asplenia syndrome.

Jun Yasuhara, Takashi Kumamoto, Takuro Kojima, Hiroyuki Shimizu, Shigeki Yoshiba, Toshiki Kobayashi, Takayuki Oyanagi, Hiroyuki Yamagishi, Naokata Sumitomo,

A 1-year-old infant with asplenia syndrome and congenital heart disease consisting of common atrium, common inlet left ventricle with a common atrio-ventricular (AV) valve, pulmonary atresia, and total anomalous pulmonary venous connection was admitted to our hospital for radiofrequency catheter ablation (RFCA) of supraventricular tachycardia (SVT) before total cavo-pulmonary connection. ...

Successful management of living donor liver transplantation for biliary atresia with single ventricle physiology-from peri-transplant through total cavopulmonary connection: A case report.

Yohei Yamada, Ken Hoshino, Takayuki Oyanagi, Ryohei Gatayama, Jun Maeda, Nobuyuki Katori, Yasushi Fuchimoto, Taizo Hibi, Masahiro Shinoda, Kentaro Matsubara, Hideaki Obara, Ryo Aeba, Yuko Kitagawa, Hiroyuki Yamagishi, Tatsuo Kuroda,

Children with single ventricle physiology have complete mixing of the pulmonary and systemic circulations, requiring staged procedures to achieve a separation of these circulations, or Fontan circulation. The single ventricle physiology significantly increases the risk of mortality in children undergoing non-cardiac surgery. As liver transplantation for patients with single ventricle ... Read more >>

Ultrasound-guided needle aspiration of epidural hematoma in a neonate after vacuum-assisted delivery.

Motomi Noguchi, Joji Inamasu, Fukiko Kawai, Emiko Kato, Takumi Kuramae, Takayuki Oyanagi, Tsutomu Takahashi, Masahiro Ihara,

Epidural hematoma (EDH) is a rare complication of vacuum-assisted delivery in neonates. Although the standard treatment of EDH is surgical evacuation via craniotomy, it is an invasive procedure in neonates, and less invasive methods may be favored for hematoma evacuation.We report a case of 5-day-old infant with a massive EDH, ...
