BACKGROUND The design of a percutaneous implantable prosthetic heart valve has become an important area for investigation. A percutaneously implanted heart valve (PHV) composed of 3 bovine pericardial leaflets mounted within a balloon-expandable stent was developed. After ex vivo testing and animal implantation studies, the first human implantation was performed in a 57-year-old man with calcif...

Adult spinal motoneurons can regenerate their axons into a peripheral nerve (PN) graft following root avulsion injury if the graft is implanted immediately after the lesion is induced. The present study was designed to determine how avulsed motoneurons respond to a PN graft if implantation takes place a few days to a few weeks later. Survival, regeneration, and gene expression changes of injure...

The case of a 36 year old woman who experienced a late, spontaneous breast seroma 5 years after augmentation in the absence of any known precipitating factors is reported. Although seroma is not an uncommon complication in the immediate postoperative period, it is extremely rare as a late complication of breast implantation. Magnetic resonance imaging is a reliable method to confirm the diagnos...

Inhalation of Beryllium (Be) dust, or its vapors or compounds, or subcutaneous implantation of Beryllium can lead to either acute or chronic beryllium disease, also known as berylliosis. It can affect genetically susceptible individuals or workers exposed to the fumes or vapors of the metal. It was first described by Hardy and Tabershaw in 1946. Beryllium can cause either an immediate acute for...

The survival of three bacterial species and Candida albicans was studied on SPI-ARGENT II. The immediate recovery from silver-impregnated polymer and control polymer (1 cm2) was approximately 10(6) to 10(7) microorganisms. After incubation (37 degreesC) and neutralization of silver with horse serum (5%), surviving organisms were recovered. The survival of the microorganisms on the polymer was n...

Aortic root rupture and cardiac tamponade during transcatheter aortic valve implantation is a frightening complication with high mortality rate. A conservative management of this complication could represent an initial strategy, especially in high-risk patients, to avoid emergent cardiac surgery. This conservative management includes: Immediate detection of pericardial effusion by echocardiogra...

PURPOSE: The ideal monitoring tool to evaluate free flap success should be minimally invasive, continuous, costeffective and reliable. Our group has previously introduced implantable oxygen sensors as a mean to monitor flaps in the immediate post-operative period and detect acute vascular compromise. The purpose of the current study was to compare and contrast intradermal vs. subcutaneous impla...

Complete atrioventricular (AV) block is a rare affection in children. It is the consequence of abnormal conduction tissue within a cardiac malformation or it is due to cardiac injury. Yet the etiology of late complete atrioventricular block in child remains mostly unknown. The treatment of children's Complete atrioventricular block is the implantation of a pacemaker with immediate results satis...
