Contributing factors to heparin resistance during cardiopulmonary bypass
Journal of Artificial Organs - - Trang 1-8 - 2024
Tomoaki Yamashiro, Yoshiyuki Takami, Yasushi Takagi
Since the risk factors for heparin resistance (HR) before cardiopulmonary bypass (CPB) have not been fully clarified, this study investigated the contributing factors for HR after the initial unfractionated heparin (UFH) dose of 500 IU/kg. We retrospectively analyzed the data of 371 patients who underwent CPB surgery, with the initial UFH dose of 500 IU/kg, between May 2017 and December 2021. We d...... hiện toàn bộ
Successful bridge to recovery in a patient surviving fatal device-related complications after implantation of a Toyobo left ventricular assist system
Journal of Artificial Organs - Tập 14 - Trang 364-366 - 2011
Gengo Sunagawa, Takafumi Masai, Koji Takeda, Masaru Ishida, Takashi Yamauchi, Yoshiki Sawa
Emergent left ventricular assist system (LVAS) removal due to device complication is associated with high morbidity and mortality. This report describes a case of a 51-year-old man with dilated cardiomyopathy who successfully underwent emergent LVAS removal after a device-related complication. Although the patient’s left ventricular function was still compromised, LVAS removal was indicated second...... hiện toàn bộ
Impact of bloodstream infections on catheter colonization during extracorporeal membrane oxygenation
Journal of Artificial Organs - Tập 19 - Trang 128-133 - 2015

There are concerns about secondary extracorporeal membrane oxygenation (ECMO) catheter infections in bacteremic patients. We investigated the association between blood stream infection (BSI) and ECMO catheter colonization. From January 2012 to August 2014, 47 adults who received ECMO support were enrolled. The ECMO catheter tip was cultured at the end of the ECMO procedure. The enrolled patients ...... hiện toàn bộ
Development of sutureless vascular connecting system for easy implantation of small-caliber artificial grafts
Journal of Artificial Organs - Tập 8 - Trang 119-124 - 2005
Osamu Sakai, Yasuhide Nakayama, Yasushi Nemoto, Yoshihiro Okamoto, Taiji Watanabe, Keiichi Kanda, Hitoshi Yaku
A novel sutureless vascular connecting system, an assembly with a delivery rod, an introducing sheath, and a connecting device, was developed for easy implantation of small-caliber vascular grafts less than 2 mm in internal diameter. A microporous stainless tube (length 2 mm, external diameter 1.6 mm, wall thickness 65 µm, pore diameter 400 µm, pore-to-pore distance 500 µm) was designed to serve a...... hiện toàn bộ

Preoperative iodine-123 meta-iodobenzylguanidine imaging is a novel predictor of left ventricular reverse remodeling during treatment with a left ventricular assist device
Journal of Artificial Organs - Tập 19 - Trang 29-36 - 2015
Teruhiko Imamura, Koichiro Kinugawa, Daisuke Nitta, Osamu Kinoshita, Kan Nawata, Minoru Ono
Although left ventricular reverse remodeling (LVRR) is accompanied with an improved clinical course during LV assist device (LVAD) treatment, its preoperative prediction remains uncertain. Twenty-seven heart failure patients with dilated cardiomyopathy were enrolled in this study. Patients underwent 123I-meta-iodobenzylguanidine (MIBG) scintigraphy before LVAD implantation, and were monitored at o...... hiện toàn bộ
Structural valvular deterioration of Hancock standard valve in the mitral position 33 years after initial implantation
Journal of Artificial Organs - Tập 19 - Trang 408-410 - 2016
Hiroyuki Saisho, Keiichiro Tayama, Koichiro Shimoishi, Hidetsugu Hori, Teiji Okazaki
A 77-year-old woman who had undergone mitral valve replacement (MVR) with a 29 mm Hancock standard (H–S) bioprosthesis (Model 242) and tricuspid annuloplasty (Kay’s method) at the age of 44 years was admitted urgently with acute heart failure. Echocardiography showed severe transvalvular leakage of the prosthesis and moderate tricuspid regurgitation. The patient underwent reMVR with a 29 mm Carpen...... hiện toàn bộ
Early clinical outcomes of right ventricular outflow tract reconstruction with small caliber bovine jugular vein conduit (Contegra®) in small children
Journal of Artificial Organs - Tập 19 - Trang 364-371 - 2016
Takashi Kido, Takaya Hoashi, Koji Kagisaki, Toshiki Fujiyoshi, Masataka Kitano, Kenichi Kurosaki, Isao Shiraishi, Toshikatsu Yagihara, Yoshiki Sawa, Hajime Ichikawa
This study reviewed early clinical outcomes of right ventricular outflow tract reconstruction with Contegra® valved conduits in pediatric patients. Between April 2013 and July 2014, thirteen pediatric patients underwent right ventricular outflow tract reconstruction with Contegra valved conduits. The size of the implanted conduits were 12 mm in 5 patients, 14 mm in 3, 16 mm in 3, and then 2 patien...... hiện toàn bộ
