OBJECTIVES The aim of this study was to evaluate the immediate and long-term outcome of intracoronary stent implantation for the treatment of coronary artery bifurcation lesions. BACKGROUND Balloon angioplasty of true coronary bifurcation lesions is associated with a lower success and higher complication rate than most other lesion types. METHODS We treated 131 patients with bifurcation les...

PURPOSE Immediate implantation presents challenges regarding site healing, osseointegration, and obtaining complete soft-tissue coverage of the extraction socket, especially in the posterior area. This last issue is addressed herein using the double-membrane (collagen membrane+high-density polytetrafluoroethylene [dPTFE] membrane) technique in two clinical cases of posterior immediate implant p...

accurate delivery of torque to implant screws is critical to generate ideal preload in the screw joint and to offer protection against screw loosening. mechanical torque-limiting devices (mtlds) are available for this reason. in this study, the accuracy of one type of friction-style and two types of spring-style mtlds at baseline, following fatigue conditions and sterilization processes were de...

conclusions this study revealed that the type of hearing loss, presence in the rehabilitation program, and the age of cochlear implantation can be major prognostic factors of the response to the treatment, then the country’s health policy makers and health planners must executively take into account the infants’ hearing screening program during the first 6 month of age. results the mean and the...

BACKGROUND There is controversy regarding the immediate and long-term effects of PTCA on the coronary flow reserve. METHODS AND RESULTS A total of 54 patients with 1-vessel disease and normal left ventricular function were studied after balloon angioplasty (n=34) or stent implantation (n=20). Distal coronary blood flow velocity reserve (CFR) was defined as the ratio of adenosine-induced hyper...

BACKGROUND Incomplete stent apposition (ISA) is an unusual finding of intravascular ultrasound (IVUS) that may occur both after drug-eluting stent (DES) or bare-metal stent (BMS) implantation and could be associated with late stent thrombosis. Controversy still remains about whether the risk of late-acquired ISA is increased after DES implantation. This meta-analysis aimed to clarify whether DE...

Fecal incontinence (FI) is the involuntary passage of fecal material. Current treatments have limited successful outcomes. The objective of this study was to develop a large animal model of passive FI and to demonstrate sustained restoration of fecal continence using anorectal manometry in this model after implantation of engineered autologous internal anal sphincter (IAS) biosphincters. Twenty...

Previous animal study revealed that post-implantation electrical detection levels significantly declined within days. The impact of cochlear implant (CI) insertion on human auditory pathway in terms of impedance and electrically evoked compound action potential (ECAP) variation within hours after surgery remains unclear, since at this time frequency mapping can only commence weeks after implant...

OBJECTIVES We performed this study to investigate the vascular response in early period after zotarolimus-eluting stent (ZES) (Endeavor Sprint, Medtronic CardioVascular, Minneapolis, Minnesota) implantation. BACKGROUND The ZES has different characteristics, with biocompatible polymer and rapid drug-elution, compared with the first-generation drug-eluting stents (DES). METHODS The ENDEAVOR O...
