BACKGROUND Cell transplantation is emerging as a potential means of improving repair of damaged organs. This preliminary study tests the feasibility of grafting allogenic cells into the border zone of a myocardial infarct (MI). METHODS AND RESULTS Neonatal cardiomyocytes were obtained from fetuses of female rats 20 days pregnant. They were then injected(More)
In this study, we present a 55-year-old female patient who suffered from atrial septal defect (ASD) and retrosternal toxic goitre simultaneously. The patient had been treated with a 300 mg/day dose of propylthiouracil for 20 days prior to operation. This patient has been operated on for both disorders and has recovered.
Between January 1983 and December 2000, 78 patients underwent primary repair of a ventricular septal defect. There were 42 males (54%) and 36 females (46%) of whom 13 (17%) were under 1 year old, 50 (64%) were aged 1-10 years, 11 (14%) were aged 10-20 years, and 4 (5%) were over 20 years old. The ventricular septal defect was a perimembranous type in 60(More)
Infective endocarditis related to pacemaker is a rare but serious condition in permanent venous tracing. A 65-year-old man was admitted to the hospital with high fever and chills. A DDD pacemaker had been implanted via the right subclavian vein because of sick sinus syndrome 6 years earlier. Transesophageal echocardiogram identified an oscillating round(More)
In this study, we examined the adherence of slime-producing standard Staphylococcus epidermidis strain ATCC 12228 to Dacron and polytetrafluoroethylene (PTFE) grafts in in vitro medium either containing salicylate or not. Dacron and PTFE graft pieces of standard size were placed in trypticase soy broth either containing 5 mM acetylsalicylic acid solution or(More)
PURPOSE The reliability of poly-p-dioxanone (PDS) suture for sternal closure was tested on 264 consecutive sternotomies in the authors' department from April 1987 to May 1998. METHODS The reason for sternotomy was tetralogy of Fallot in 65 cases (24.6%), ventricular septal defect (VSD) in 38 cases (14.4%), atrial septal defect (ASD) in 77 cases (29.2%),(More)
The ability of retrograde warm blood cardioplegia to preserve hypertrophied myocardium remains controversial. This two-part study was undertaken to address this question in patients subjected to aortic valve replacement for calcified aortic valve stenosis complicated with echocardiographically defined left ventricular hypertrophy. Part 1 was designed to(More)
Pancreaticoduodenal artery aneurysms (PDAAs) are rarely seen among the visceral artery aneurysms (<2%). PDAA is mostly asymptomatic but can be presented with abdominal pain. Embolization can be applied safely with a high success rate; however, in some conditions such as when embolization fails or accompanying celiac axis occlusion, open surgery can be(More)
