Aqueous shunt has emerged as an alternative technique to trabeculectomy, considered the standard for glaucoma surgery. Currently, it is mainly indicated after failure of trabeculectomy or in glaucoma with high risk of failure. The Ahmed valve and the Baerveldt implant are the most commonly used aqueous shunts. However, it is not clear whether there are differences between them.
The effect of subconjunctival bevacizumab injection on the outcome of ahmed glaucoma valve (AGV) implantation.
To report the outcomes of Silicone Ahmed Glaucoma Valve (AGV) implantation in the management of refractory pediatric glaucoma.
For many years, anticoagulant therapy had been deemed unacceptable for civilian pilot medical certification in the United Kingdom under the Joint Aviation Authorities Requirements and, therefore, mechanical valve implants were disqualifying. In 2012, this restriction was removed by implementation of the European Union requirements. This study was undertaken to assess the medical evidence available to develop a certificatory policy following mechanical valve implants in the United Kingdom.
To apply propensity score matching to Ahmed glaucoma drainage implants (AGI) to trabectome-mediated ab interno trabeculectomy (AIT). Recent data suggests that AIT can produce results similar to AGI traditionally reserved for more severe glaucoma.
Aortic valve-in-valve implantation for prosthetic valve dysfunction is a good alternative to reoperative valve replacement. There are some limitations to this approach including the risk of coronary occlusion, patient prosthesis mismatch, and valve malposition. The incidence of coronary occlusion is higher in aortic valve-in-valve than de novo aortic stenosis cases. Multiple factors can contribute to this complication, and the type of bioprosthesis has been implicated.
Transcatheter mitral valve-in-valve (TMVIV) or valve-in-ring (TMVIR) replacement has shown early promise in patients deemed poor surgical candidates as a less invasive alternative to conventional reoperative mitral valve (MV) replacement.
Various options are available for the treatment of mitral valve insufficiency, including reconstructive approaches such as annulus correction through ring implants. The correct choice of general therapy and implant is relevant for an optimal outcome. Additional to guidelines, decision support systems (DSS) can provide decision aid by means of virtual intervention planning and predictive simulations. Our approach on virtual downsizing is one of the virtual intervention tools that are part of the DSS workflow...
If mitral valve repair is not feasible, mitral valve replacement remains the only option. Based on our overall experience with the On-X mitral valve, the aim of this study was to investigate early and late outcomes after mitral valve replacement using this latest generation prosthesis.
To analyze the behavior of platelets after transcatheter valve-in-valve implantation for the treatment of degenerated bioprosthesis and how they correlate with adverse events upon follow-up.
Transcatheter heart valve-in-valve implantation in failed surgical bioprosthetic valves has shown promising outcomes, prompting the stepwise expansion of their applications in different clinical scenarios. Recently, there is increased interest in valve-in-valve techniques for the treatment of patients with complex congenital heart disease. Herein, we report a case of successful transapical transcatheter atrioventricular valve-in-valve implantation in a patient with Fontan circulation and dextrocardia. The p...
A 74-year-old man presented with progressive dyspnea on exertion. History included peripheral arterial disease and coronary artery bypass grafting with aortic valve replacement 12 years ago. Subsequently, the surgical valve developed severe stenosis and moderate insufficiency. He underwent a transapical valve-in-valve transcatheter aortic valve replacement 5 years before presentation. This second valve developed a mean gradient of 66 mm Hg with mild insufficiency. The patient was treated with a third aortic...
We present a severe sight-threatening complication from cosmetic intraocular iris implantation, highlighting the dangers of iris implants and medical tourism. Intraocular iris implants are single-piece silicone prostheses implanted in the anterior chamber. These devices were initially developed for the treatment of aniridia, however, more recently these devices have been marketed as a cosmetic procedure to individuals who wish to surgically change their eye colour.
Optimal surgical treatment of infective tricuspid endocarditis is debatable, especially in the setting of inherent social and pathologic concerns. This study seeks to compare tricuspid valve repair, replacement, and excision for the treatment of infective endocarditis METHODS: A single center cardiac surgery database was queried between 2012 and 2016 to identify patients >18 years who underwent tricuspid valve surgery for infective endocarditis. Patients were divided into 3 groups based on the type of tricu...
Recent systematic reviews point to the scarcity of single implants followed up longer than 5 years, and the incidence of biologic/technical complications is underreported. This prospective follow-up study documents 8- to 10-year clinical outcomes of immediately restored single implants in extraction sockets (immediate implant treatment [IIT]) and healed bone (conventional implant treatment [CIT]). Patients received a single, chemically modified, moderately rough titanium implant and a provisional crown on t...
To report on the Chinese multicenter study of the J-Valve transcatheter heart valve for treatment of predominant aortic regurgitation.
In the TAVR (transcatheter aortic valve replacement) era, trans-apical valve-in-valve mitral valve implantation (TA-MVI) is considered an alternative treatment for high risk patients with degenerated mitral bioprosthesis. We report an unusual strategy to remedy to a potentially fatal complication as the mitral prosthesis migration into the aortic arch. The dislocated prosthesis was successfully stabilized in the aortic arch with a bare aortic stent, ensuring an adequate perfusion of epiaortic vessels.
This prospective cohort study assessed the effect of bone quality on the primary and secondary stability of single short implants placed in the posterior region.
In the last decade, several studies have reported that short implants achieve excellent results with a 2-stage technique. According to the literature, short dental implants have often been used for the replacement of teeth.
Single post-extractive ultra-wide 7-mm-diameter implants versus implants placed in molar healed sites after socket preservation. Tallarico M, Xhanari E, Pisano M, De Riu G, Tullio A, Meloni SM. Eur J Oral Implantol 2016;9(3):263-75.
The purpose of this study is to analyze the static magnetic field interactions for an ophthalmic-magnetic shunt implant with a ferromagnetic steel plate in a thin silicon layer. The plate is used for opening of a valve flap. Ten different sizes of this steel plate were investigated to characterize the relationship between the size of the metal and the magnetic forces of the static magnetic field of a 3.0 T MRI.
This study evaluated retrospectively the effectiveness of the veterinary cuttable plate (VCP) in a plate-rod construct, for the treatment of diaphyseal femoral fractures in cats.
The objective of this study was to determine whether valve-in-valve transcatheter aortic valve implantation (VIV-TAVI) is associated with better survival than redo surgical aortic valve replacement (SAVR) in patients with degenerated aortic valve bioprostheses, and we performed a meta-analysis of comparative studies.
Several primate neurophysiology laboratories have adopted acrylic-free, custom-fit cranial implants. These implants are often comprised of titanium or plastic polymers, such as polyether ether ketone (PEEK). Titanium is favored for its mechanical strength and osseointegrative properties whereas PEEK is notable for its lightweight, machinability, and MRI compatibility. Recent titanium/PEEK implants have proven to be effective in minimizing infection and implant failure, thereby prolonging experiments and opt...
