Animal experimental implantation of an atrial septal defect occluder system. (1/868)

OBJECTIVE: To establish the implantation technique for the atrial septal defect occluder system (ASDOS) device in an experimental animal model and to determine long term mechanical stability of the device and its in vivo properties in terms of biocompatibility and tissue reaction. MATERIALS AND METHODS: An atrial septal defect was created and the device implanted in 17 pigs (mean weight 30 kg). The implantation technique was refined and modified because of initial technical and anatomical complications during nine acute pilot studies. The technique proved to be feasible in eight subsequent survival studies. Four pigs were electively killed three months after implantation (group 1). The remaining four pigs were killed six months after implantation (group 2). RESULTS: Necropsy showed all devices were embedded in soft tissue three months after implantation. Microscopic examination of atrial septal tissue showed an acute granulomatous inflammatory reaction in group 1 and fibrosis in group 2. The intensity of the inflammatory reaction around the device was clearly milder in group 2, indicating a decline in the inflammatory response with time. Clinical and biochemical investigations indicated acceptable biocompatibility of the device. CONCLUSION: The implantation technique for the ASDOS device in a chronic pig model has been established. Biocompatibility of the device was acceptable.  (+info)

Transdermal photopolymerization for minimally invasive implantation. (2/868)

Photopolymerizations are widely used in medicine to create polymer networks for use in applications such as bone restorations and coatings for artificial implants. These photopolymerizations occur by directly exposing materials to light in "open" environments such as the oral cavity or during invasive procedures such as surgery. We hypothesized that light, which penetrates tissue including skin, could cause a photopolymerization indirectly. Liquid materials then could be injected s.c. and solidified by exposing the exterior surface of the skin to light. To test this hypothesis, the penetration of UVA and visible light through skin was studied. Modeling predicted the feasibility of transdermal polymerization with only 2 min of light exposure required to photopolymerize an implant underneath human skin. To establish the validity of these modeling studies, transdermal photopolymerization first was applied to tissue engineering by using "injectable" cartilage as a model system. Polymer/chondrocyte constructs were injected s.c. and transdermally photopolymerized. Implants harvested at 2, 4, and 7 weeks demonstrated collagen and proteoglycan production and histology with tissue structure comparable to native neocartilage. To further examine this phenomenon and test the applicability of transdermal photopolymerization for drug release devices, albumin, a model protein, was released for 1 week from photopolymerized hydrogels. With further study, transdermal photpolymerization potentially could be used to create a variety of new, minimally invasive surgical procedures in applications ranging from plastic and orthopedic surgery to tissue engineering and drug delivery.  (+info)

Transcatheter closure of a mid-muscular ventricular septal defect with an amplatzer VSD occluder device. (3/868)

A 5 year old girl with a haemodynamically significant mid-muscular ventricular septal defect (VSD) had successful transcatheter closure using the Amplatzer VSD occluder. This device passes through a small diameter sheath and can be easily retrieved or repositioned. These properties may make it a suitable device for closure of large mid-muscular defects in small children.  (+info)

Limb salvage surgery in bone tumour with modular endoprosthesis. (4/868)

Thirty-three patients with bone tumours were treated by resection of the growth and reconstruction with a Kotz modular endoprosthesis. The average follow-up was for 50 months, ranging from 14 to 79 months. At the last review, 12 patients (36%) had died due to the tumour and 9 others (27%) had metastases. All 4 patients with proximal tibial reconstruction had poor functional results, due to an extension lag or to knee stiffness. Four of the six tumours of the proximal femur were complicated by local recurrence or dislocation of the hip, and had poor or fair functional results. Of the patients with distal femoral reconstruction, 17 out of 22 had excellent or good functional results. Reconstruction with a modular prosthesis after resection of a tumour gives excellent or good functional results in more than three-fourths of the cases of distal femur reconstruction, but it should be used with caution in the proximal tibia and proximal femur.  (+info)

Transcatheter closure of muscular ventricular septal defects with the amplatzer ventricular septal defect occluder: initial clinical applications in children. (5/868)

OBJECTIVES: The aim of this study was to close muscular ventricular septal defects (MVSDs) in children, with a new device, the Amplatzer ventricular septal defect occluder (AVSDO). BACKGROUND: The design of previously used devices for transcatheter closure of MVSDs is not ideal for this purpose and their use has been limited by several drawbacks. METHODS: Six patients, aged 3 to 10 years, with MVSDs underwent transcatheter closure using the AVSDO. The device is a modified self-centering and repositionable Amplatzer device that consists of two low profile disks made of Nitinol wire mesh with a 7-mm connecting waist. The prosthesis size (connecting waist diameter) was chosen according to the measured balloon stretched VSD diameters. A 6-F or 7-F sheath was used for the delivery of the AVSDO. Fluoroscopy and transesophageal echocardiography were utilized for optimal guidance. RESULTS: The location of the defect was midmuscular in five patients and beneath the pulmonary valve in one. The balloon stretched MVSD diameter ranged from 6 to 11 mm. Device placement was successful in all patients, and complete occlusion occurred in all six patients (95% confidence interval 54.06% to 100%). Two patients developed transient complete left bundle branch block. No other complications were observed. CONCLUSIONS: This encouraging initial clinical success indicates that the AVSDO is a promising device for transcatheter closure of MVSDs in children. Further clinical trials and longer follow-up are needed before the widespread use of this technique can be recommended.  (+info)

Improved survival rates support left ventricular assist device implantation early after myocardial infarction. (6/868)

OBJECTIVES: Implantation of left ventricular assist devices (LVADs) early after acute myocardial infarction (MI) has traditionally been thought to be associated with high mortality rates due to technical limitations and severe end-organ dysfunction. At some experienced centers, doctors have refrained from earlier operation after MI to allow for a period of hemodynamic and end-organ stabilization. METHODS: We retrospectively investigated the effect of preoperative MI on the survival rates of 25 patients who received a Thermocardiosystems Incorporated LVAD either <2 weeks (Early) (n = 15) or >2 weeks (Late) (n = 10) after MI. Outcome variables included perioperative right ventricular assistance (and right-sided circulatory failure), hemodynamic indexes, percent transplanted or explanted, and mortality. RESULTS: No statistically significant differences were demonstrated between demographic, perioperative or hemodynamic variables between the Early and Late groups. Patients in the Early group demonstrated a lower rate of perioperative mechanical right ventricular assistance, but had a higher rate of perioperative inhaled nitric oxide use. In addition, 67% of patients in the Early group survived to transplantation and 7% to explantation, findings comparable to those in the Late group (60% and 0% respectively). CONCLUSIONS: This clinical experience suggests that patients may have comparable outcomes whether implanted early or late after acute MI. These data therefore support the early identification and timely application of this modality in post-MI LVAD candidates, as this strategy may also reveal a subgroup of patients for whom post-MI temporary LVAD insertion may allow for full ventricular recovery.  (+info)

Artificial disc replacement with the modular type SB Charite III: 2-year results in 50 prospectively studied patients. (7/868)

The Modular Type SB Charite disc prosthesis has been developed as a device for artificial disc replacement (ADR) in patients with symptomatic discopathies. Here, we report on our first series of 50 (out of 350) patients, who had a satisfactory clinical result in 70% of cases (2 years' follow-up). Subgroup analysis revealed that patients with an isolated discopathy without previous spinal operations or other pathology at the same or other spinal level benefitted more from the surgery. However, this technique was associated with some problems: a 13% rate of permanent side-effects and/or complications was observed caused by the anterior approach. Four percent were related to poor implantation technique. There were no problems related to the material of the prosthesis. Twelve patients needed re-operation, but this was beneficial in only three of them. In one patient we had to convert to an interbody fusion. We conclude that in patients with severe isolated symptomatic discopathies that are resistant to conservative treatment, a mobile disc prosthesis is worth considering as a real alternative to a spondylodesis. However, accurate patient selection is imperative. With these criteria we were encouraged by our results to continue the implantation of this artificial disc.  (+info)

Long-term histological and electrophysiological results of an inactive epiretinal electrode array implantation in dogs. (8/868)

PURPOSE: Short-term pattern electrical stimulation of the retina via multielectrode arrays in humans blind from photoreceptor loss has shown that ambulatory vision and limited character recognition is possible. To develop an implantable retinal prosthesis that would provide useful vision, these results need to be sustained over a prolonged period of retinal electrical stimulation. As a first step toward this goal, the biocompatibility and the feasibility of surgically implanting an electrically inactive electrode array onto the retinal surface was tested. METHODS: A 5 x 5 electrode array (25 platinum disc-shaped electrodes in a silicone matrix) was implanted onto the retinal surface using retinal tacks in each of the 4 mixed-breed sighted dogs. Color fundus photography, fluorescein angiography, electroretinography, and visual evoked potentials were obtained preoperatively, at 1-week intervals for 2 weeks postoperatively, then at 2-week intervals up to 2 months postoperatively, and thereafter at 1-month intervals. One dog was killed at 2 months after implantation and a second dog after 3 months of implantation. Histologic evaluation of the retinas was performed. The remaining two dogs continue to be followed beyond 6 months after the implantation surgery. RESULTS: No retinal detachment, infection, or uncontrolled intraocular bleeding occurred in any of the animals. Retinal tacks and the retinal array remained firmly affixed to the retina throughout the follow-up period. Hyperpigmentation of the retinal pigment epithelium was observed only around the site of retinal tack insertion. No fibrous encapsulation of the implant or intraocular inflammation was visible. A- and b-wave amplitudes of the electroretinogram were depressed at the first postoperative week testing but recovered over the ensuing 1 week and were not statistically different from the normal unoperated fellow eye throughout the postoperative period. N1 and P1 wave amplitudes of the visual evoked potentials were not significantly different from the normal fellow eyes at any of the postoperative test intervals. Fluorescein angiography showed that the entire retina including the area under the electrode array remained well perfused. Similarly, histologic evaluation revealed near total preservation of the retina underlying the electrode array. CONCLUSIONS: Implantation of an electrode array on the epiretinal side (i.e., side closest to the ganglion cell layer) is surgically feasible, with insignificant damage to the underlying retina. The platinum and silicone arrays as well as the metal tacks are biocompatible. With the success of implanting an electrically inactive device onto the retinal surface for prolonged periods, the effects of long-term retinal electrical stimulation are now ready to be tested as the next step toward developing a prototype retinal prosthesis for human use.  (+info)

Anesthesia was induced and maintained with midazolam and fentanyl. Transesophageal echocardiography (TEE) and a PA catheter were useful for hemodynamic monitoring and management of the patients. Furthermore, TEE is useful for the early detection of inflow of the air which is absorbed by negative pressure derived from high LVAD support pressure. On starting LVAD support, evaluation of right ventricular function and treatment for right ventricular failure were important and necessary for the patients. Added to conventional therapy using catecholamines, inhaled nitric oxide may provide a ...

N2 - The increased applicability and excellent results with left ventricular assist devices (LVADs) have revolutionized the treatment options available for patients with end-stage heart failure. Until recently, most patients who have undergone LVAD implantation have been supported by pulsatile devices. Unfortunately, the use of the latter devices is associated with significant comorbidity, primarily as a result of their large size and limited durability. The HeartMate II and the Jarvik 2000 pumps, both of which incorporate axial-flow and rotary pump technology represent the next generation of devices. The clinical use of these newer axial-flow pumps have resulted in superior outcomes, including significantly reduced complication rates with improved durability. However, as with all new technology, axial-flow LVADs have also introduced a ...

Following ventricular assist device (VAD) implantation, and observing conventional post-operative care, most patients should be able to be weaned from mechanical ventilation and woken within a few hours, providing that they remain hemodynamically stable and meet CMV weaning criteria. To ensure a patients hemodynamic stability during the early postoperative period, they must maintain a normal sinus rhythm, mean arterial blood pressure (MAP) of 60-80mmHg, central venous (CVP) and pulmonary artery wedge (PAWP) pressures less than 15mmHg and a cardiac index above 2.51min-1m-2. Although CMV weaning criteria can differ depending on the institution, recommended criteria includes pH ,7.25, partial pressure of oxygen in the arterial blood (PaO2) ,60mmHg, fraction of inspired oxygen (FIO2) ,0.4, PaO2/FIO2 (P/F) ratio ,150mmHg, positive end expiratory pressure (PEEP) , 8cmH2O, and the patients capability of triggering the ventilator [14]..

In the present retrospective study, we have demonstrated that stroke after LVAD implantation has a right hemispheric predominance and right hemispheric stroke after LVAD implantation was more often associated with infection compared with left hemispheric stroke. The incidence of stroke after LVAD placement was reported previously to be 8.0% to 25.0%.2,4 The overall incidence of stroke in our cohort was 12.9%.. Regarding the hemispheric distribution of stroke, the results of our observation are consistent with previous reports describing the mechanism of right-hemispheric dominance of cardiogenic embolisms after cardiac surgery.5-8 Considering any thrombus inside the LVAD pump as a part of cardiac embolic material in addition to actual intracardiac thrombi, right-to-left propensity of stroke after LVAD can be easily explained by anatomic alignment of the arteries arising from aortic arch. Moreover, surgical manipulation of LVAD outflow cannula-to-ascending aorta anastomosis may also direct ...

The SCID mouse model for rheumatoid arthritis (RA) is an established and reliable approach to examining the distinct mechanisms operative in RA synovium, and evaluating novel gene therapy strategies. However, serum concentrations of circulating gene therapy products following gene transfer are frequently too low to allow detection. This problem stimulated us to develop a novel implantation technique to improve the yield of these soluble gene products. Synovial fibroblasts from patients with RA were cultured, passaged, and transduced with Ad5 sTNFRp55:Ig. sTNFRp55:Ig production was confirmed by ELISA, and then cells were implanted into SCID mice using a novel implantation strategy in which pieces of human cartilage were engrafted into a fibroblast-saturated inert sponge. Thereafter, the sponges were implanted under the skin of the mice instead of under the kidney capsule, as in the original approach, allowing co-implantation of larger pieces of cartilage together with higher numbers of ...

Background: In this study, we aimed to investigate frequency, patterns, etiologies, and costs of unplanned readmissions after left ventricular assist device implantation.. Methods: Between April 2012 and September 2016, 99 unplanned readmissions of a total of 50 consecutive bridge-to-transplant patients (45 males, 5 females; mean age 46.9±10.3 years; range, 19 to 67 years) who were successfully discharged after left ventricular assist device implantation were retrospectively analyzed. Patient demographic data, hemodynamic measurements before implantation, and readmissions after discharge were recorded. Hospitalizations due to major problems which were unable to be managed in routine outpatient clinic were accepted as unplanned readmissions. Survival analysis was performed..

Forty-two eyes of 26 patients, 14 men and 12 women, with postoperative keratectasia after PRK (8 eyes, Group A) and LASIK (34 eyes, Group B) were included in a nonrandomized, retrospective, observational case series. Mean age at the time of ICRS implantation was 30.5 years. Mean follow-up was 23,5 months (range, 1 to 86 months). Corneal tunnels were created by means of mechanical dissection in all eyes. Main outcome measures included UCVA, BCVA, refraction, keratometry and computerized analysis of corneal topography.. ...
Both Kerarings and Intacs have been shown to be an effective method of improving vision when used in isolation for patients with keratoconus. In 2014 Torquetti et al. [17] published data showing that Kerarings could effectively improve UDVA and CDVA in patients with keratoconus. Fahd et al. [18] showed Intacs to be safe and effective when used to treat eyes with moderate to severe keratoconus. However, recent data has suggested that there is regression in visual, refractive and topographic measures 5 years after ISCRS implantation [19]. This regression is to be expected as although the ISCRS flatten the cornea, they do not prevent the progression of the disease itself. CXL has therefore been used in combination with ISCRS to address this and provide the maximal visual improvement for the patient [20-22]. Our data shows ISCRS (INTACS and Kerarings) combined with CXL treatment to be a safe and effective treatment for keratoconus. We found both INTACS and Kerarings combined with CXL to produce a ...

N2 - Background: The use of ventricular assist devices (VADs) in children with heart failure may be of particular benefit to those with accompanying renal failure, as improved renal function is seen in some, but not all recipients. We hypothesized that persistent renal dysfunction at 7 days and/or 1 month after VAD implantation would predict chronic kidney disease (CKD) 1 year after heart transplantation (HT). Methods: Linkage analysis of all VAD patients enrolled in both the PEDIMACS and PHTS registries between 2012 and 2016. ...

Methods and Results Using a large US commercial insurance database, patients who received an LVAD (International Classification of Diseases, 9th Revision, Clinical Modification code 37.66) and survived to hospital discharge without heart transplantation between January 1, 2006, and March 31, 2015, were identified. Heart failure medication use from 3 months before 1‐year post‐LVAD was examined using linked pharmacy claims. Differences in the proportion of patients taking heart failure medications post LVAD compared with pre LVAD were examined using McNemar test. Predictors of post‐LVAD medication use and poor medication adherence (proportion of days covered ,0.8) were identified via logistic regression. Among 362 patients (mean age, 57.4 years; 75.1% men), compared with pre LVAD, the proportion of patients taking anticoagulants and antiarrhythmics following LVAD increased; mineralocorticoid receptor antagonists, thiazide diuretics, and digoxin decreased; and β‐blockers, ...

PUNDI, BHARATRAM SATYANARAYANAN. Class-E Power Amplifier Design and Back-Telemetry Communication for Retinal Prosthesis. (Under the direction of Wentai Liu.) This thesis discusses the power link in the retinal prosthesis project that aims to provide vision to the profoundly blind. Clinical experiments have confirmed that electrical stimulation can be used to duplicate the action of photoreceptors in the retina to provide vision to blind patients suffering from RP/AMD. The retinal prosthesis system consists of an intraocular unit implanted inside the eye and a separate extraocular unit. The microstimulator involved in retinal prosthesis consists of multiple electrodes arranged in twodimensional array and is a part of the intraocular unit. The micro-stimulator needs data and power to be transferred wirelessly from the extraocular unit. The power link consists of a highly efficient Class-E driver that transfers power inductively to the intraocular unit. A Class-E power driver is developed to suit ...

Introduction: Stenosis in the continuous-flow left ventricular assist device (CF-LVAD) outflow graft can be caused by various mechanical and anatomical factors. Increasingly, percutaneous management has been utilized to re-establish adequate CF-LVAD flow. We sought to evaluate indications for such interventions and their outcomes. Methods: An electronic search was performed to identify all studies in the English literature reporting CF-LVAD outflow graft stenting for various etiologies. Twenty-one studies consisting of 26 patients were included in the analysis. Results: Median patient age was 59 years [45.8-67.0] and 65.4% (17/26) were male. 58.3% (14/24) of patients had HeartWare HVAD, 37.5% (9/24) had HeartMate II LVAD, and 4.2% (1/24) had HeartMate III LVAS. Median time from device placement to outflow graft stenting was 24.0 months [7.8-30.4]. 76.9% of patients (20/26) presented with heart failure. 34.6% (9/26) had outflow graft thrombosis, 34.6% (9/26) stenosis, 11.5% (3/26) kinking, 11.5% (3/26)

Background: Acute heart failure (AHF) is the first cause of hospitalization for over-65 individuals, associated with high mortality and readmission rate. The aim of this study was to assess the prognostic value of a multiparametric score combining clinical, biochemical and echocardiographic indexes in AHF for clinical practice.. Methods: 830 patients hospitalized for AHF were enrolled. Exclusion criteria were: active neoplasms; previous heart transplantation or left ventricular assist device implantation. Different variables were analyzed: etiology of AHF, clinical and biochemical data, lung congestion on chest-X ray, echocardiographic parameters and administered therapy. The endpoints were: all-cause mortality at 30 days, 6 months and 5 years and the duration of hospitalization.. Results: 771 patients met eligibility criteria. Using the univariate and multivariate analysis the indexes with the best correlation with outcome were discretized and used to create the ACUTE HF score, computed as: ...
Driveline or device infection may complicate left ventricular assist device implants, and only curative option may be pump exchange. Replacement with similar device may be liable to reinfection, because pump configuration is such that the new device and driveline may partly lie within the pocket of the previous pump. One approach to overcome this is using a different pump design such that the new pump would lie in a different location from the old pump. We describe treatment of severe HeartMate II (Abbott, [St Jude Thoratec Corp], Pleasanton, CA USA) left ventricular assist device infection by minimally invasive exchange to an intrapericardial HVAD (HeartWare International, Inc, Framingham, MA USA) left ventricular assist device ...

Enrollment in the international clinical trial was completed in December 2008, while the first 50 commercial implants occurred between January and September in 2009. In all, 10 centers (five clinical trial sites, as well as five commercial sites) in five countries contributed to this data set. The average age of the 100-patient pool was 50.5 years old, with the youngest being 16 years old.. Dr. Strueber, a principal investigator in the original international trial, noted that 14 percent of the implants were conducted by thoracotomy, with 86 percent through a typical sternotomy, thereby reinforcing the versatility of the HeartWare® HVAD® pump and potential for less invasive procedures in the future.. Duration of support averaged 444 days in the clinical trial population, compared with 203 days in the more recently implanted commercial group. The longest duration of support was 1,108 days. Seven patients were transplanted within 180 days in the clinical trial group, compared to four in the ...

Out of the five senses that you have, which is the one that you would deem to be most important? It would be an extremely difficult question for me to answer, as I treasure my sight, smell, touch, taste and hearing equally - and lacking in one is more than enough to make life difficult. Having said that, I salute the indomitable human spirit and those who have achieved so much more than normal able-bodied folks even when missing one (or more) of the five senses. Having said that, there is some hope for the blind thanks to the efforts of Second Sight who came up with the Argus II Retinal Prosthesis. This rather unique piece of technology will basically allow a blind user to see objects, as well as colors and movement within their environment. Just how is this achieved? Normally, it is done thanks to the assistance of a video-camera-equipped pair of glasses that is worn by the user. However, a recent experiment saw researchers do away with the camera, and they instead transmitted visual Braille ...
Retinal prostheses promise a potential to restore sight in millions of blind people, but new milestones in this technology have been difficult to achieve.
