[Ab] Resumo:Objectives: Bioprosthetic aortic heart valves are increasingly implanted in younger patients. Therefore, a strategy for potential valve failure should be developed before implanting the 'first valve'. The goal of this in vitro study was to provide insight into the effects of the design of a bioprosthesis on a valve-in-valve implanted Sapien XT valve. Methods: The hydrodynamic performance of a 23-mm Sapien XT valve implanted in Vascutek Aspire, Edwards Perimount, Medtronic Mosaic and St. Jude Medical Trifecta heart valves was investigated in a left heart simulator. In addition to the hydrodynamic results, the leaflet dynamics were analysed in high-speed video recordings of the tests. Results: All valve-in-valve combinations in this study fulfilled the minimum acceptance criteria defined by relevant approval standards (e.g. ISO 5840) but displayed significant differences in their performances. Small inner diameters of the bioprostheses were associated with increased mean pressure gradients, decreased effective orifice areas and geometric opening areas as well as with pin-wheeling and uneven leaflet motion. In addition, implantation in bioprostheses with internally mounted leaflets was associated with lower paravalvular leakage. Conclusions: The results of this study suggest that a surgical bioprosthesis with a large inner diameter and internally mounted leaflets improves the heamodynamics and potentially the durability of a valve-in-valve combination. These results should give the attending physicians critical information to consider when deciding on a bioprosthesis for younger patients.

[Ab] Resumo:BACKGROUND: To report a case of impending extrusion of Ex-PRESS shunt treated by shunt-position adjustment. CASE PRESENTATION: A 56-year-old Asian woman presented with impending extrusion and malposition of Ex-PRESS shunt in her left eye. The bleb of the left eye was shallow and diffuse. In the past, the patient was treated by Ex-PRESS shunt implantation under the scleral flap in both eyes. There had been no Ex-PRESS shunt-related complication in her right eye, and she reported no history of left-eye trauma. Based on these findings, we hypothesized that the source of the left-eye problem was a loosely fixed Ex-PRESS shunt spur. It was thought, furthermore, that this inadequate scleral resistance during the Ex-PRESS shunt implantation was due to the low scleral rigidity resulting from high myopia and insufficient maintenance of the anterior chamber. We proceeded to make an incision in the area adjacent to the Ex-PRESS shunt using a super sharp blade. The shunt was then pushed into the anterior chamber with forceps, and the spur was fixed firmly. Pushing the shunt to the anterior chamber was found to have been sufficient to fix it firmly. In fact, when the sclera was palpated with a sponge, aqueous outflow was observed with no shunt displacement. Postoperative intraocular pressure (IOP) was managed well, and the bleb had formed with diffuse, prominent shapes. The Ex-PRESS shunt was well sustained with good positioning. CONCLUSIONS: When an Ex-PRESS shunt operation is performed on a patient who shows a tendency for low scleral rigidity, shunt implantation should be accomplished carefully and with force adequate for firm spur fixation.

[Ab] Resumo:BACKGROUND: This study examined whether aortic valve opening (AVO) and other echocardiographic parameters influence outcomes in patients on left ventricular (LV) assist device (LVAD) support. Pump thrombosis (PT) and ischemic stroke (IS) are known complications of LVAD, but mechanisms that could influence them are not completely understood. METHODS: This was a retrospective analysis of 147 patients who received a HeartWare Ventricular Assist Device ( HeartWare International) as a bridge to transplant or to candidacy between July 2009 and August 2015, of whom 126 had at least 30 days of follow-up before the first event (30-days-out cohort). Outcomes included survival, PT, IS, and PT+IS (combined thrombotic event; CTE). RESULTS: Median time on support was 518 days. Of the 30-days-out cohort, 29% had a first PT and 19% a first IS. AVO was associated with longer survival on device (1,081 vs 723 days; p = 0.01) in the entire cohort. In the 30-days-out cohort, the aortic valve was more frequently closed in patients with lower ejection fractions on support (14% ± 6% vs 18% ± 9%; p = 0.009), more dilated pre-event echocardiogram (LV end-diastolic diameter, 66 ± 12 mm vs 62 ± 10 mm; p = 0.04), and pre-implant LV end-diastolic diameter (70 ± 10 mm vs 66 ± 9 mm; p = 0.06). CTE-free survival on the device was lower with a closed aortic valve (897 vs 1,314 days; p = 0.003) as was PT-free survival on the device (1,070 vs 1,457 days; p = 0.02). Cox regression analysis showed that AVO was an independent predictor of CTE (p = 0.03) CONCLUSIONS: Thrombotic events are relatively frequent in patients on long-term LVAD support. A closed aortic valve was associated with decreased overall survival, thrombosis-free survival, and poorer LV function on support. These are high-risk patients, so whether they require more intense anti-coagulation or prioritizing for transplantation requires further research.

[Ab] Resumo:IMPORTANCE: Long-term outcomes of an interwoven nitinol stent design represent the best in class for treatment of lower limb arterial obstructive disease METHODS: The subjects were enrolled in an open single arm study comparing the outcomes to an FDA mandated objective performance goal (OPG). RESULTS: About 325 patients (264 intention-to-treat and 64 roll-in subjects) were enrolled. Mean follow-up period was 887+/- 352 days. Treated lesion lengths were 7.8 cm ± 4.3 cm in the trial with chronic total occlusions comprising 24.6% (65/264) of subjects. Freedom from clinically driven target lesion revascularization (CD-TLR) at 12 months was 89%, at 24 and 36 months it was 84% and 82% respectively. The difference in the 12 month CD-TLR was 7% at 36 months. The difference of clinically driven-TLR at 36 months in those subjects who received their stents deployed nominally in length, compressed or elongated (between -10% and +10% nominal length) had an impact on the CD-TLR. At 2 and 3 years, freedom from CD-TLR in minimal compression was 86.7%, and was 90.0% for moderate compression. In those stents deployed with minimal, moderate, or severe elongation (10-20%, 20-40%, or >40%, respectively) freedom from CD-TLR of 84.1%, 87.4%, and 77.0% respectively at 12 months. At 2 and 3 years, freedom from CD-TLR for moderate elongation was 81.8% and 78.2%, and for severe elongation was 63.4% and 42.3%, respectively. Fractures were distinctly uncommon with this stent with a single facture event in the 36 month follow-up period. DISCUSSION: The interwoven nitinol design stent is a stent that achieves an excellent primary patency but further maintains the durability of the stent through 36 months. Optimal stent deployment remains critical to the performance of this stent device and requires optimal vessel preparation. © 2017 Wiley Periodicals, Inc.

[Ti] Título:Complications of micro-invasive glaucoma surgery.

[Ab] Resumo:PURPOSE OF REVIEW: Micro-invasive glaucoma surgery (MIGS) is gaining favor with both comprehensive ophthalmologists and glaucoma specialists due in part to its improved safety profile when compared to traditional incisional glaucoma surgery. Despite a micro-invasive approach and minimal induced tissue trauma, each MIGS procedure is associated with unique complications. The present article summarizes evidence from the 2016 to 2017 review period regarding the safety profiles of Schlemm's canal-based, suprachoroidal, and subconjunctival microstents. RECENT FINDINGS: Ab-interno microstents are subject to intraoperative malpositioning, which can result in luminal obstruction and decreased efficacy. Acutely elevated intraocular pressure (IOP) has been observed with the iStent (Glaukos Corp., Laguna Hills, CA, USA; 2-4.3%), Hydrus Microstent (Ivantis Inc., Irvine, CA, USA; 6%), Cypass Microstent (Alcon, Fort Worth, TX, USA; 3-10.8%), and Xen Gel Stent (Allergan Plc, Dublin, Ireland; 21.5%). Meanwhile, most cases of hypotony (IOP < 6 mmHg) occurred within the first postoperative month, resolved with conservative treatment and without further surgical intervention, and were not associated with vision-threatening sequelae. SUMMARY: Interest in MIGS continues to grow as these procedures allow surgeons to intervene earlier in the disease course for patients with milder stages of glaucoma. Complications associated with MIGS, albeit infrequent and mostly transient, do occur despite a less invasive approach than trabeculectomy and tube shunt surgery.

[Ti] Título:Clinical significance of superior articular process as a reference point for free-hand pedicle screw insertion in thoracic spine.

[Ab] Resumo:The trajectory of the pedicle screw perpendicular to the SAP (superior articular process) is consistent with the universal trajectory presented in the previous study of the entry point using computed tomography. The ideal entry point and trajectory of pedicle screw insertion have been a matter of considerable debate. We attempted to find the relationship between SAP and entry point and trajectory of the pedicle screw.Thoracic spine CT (computed tomography) scans of 9 volunteers were studied. A safe zone for the trajectory of the screw in the axial (MarginAx) and sagittal (MarginSag) was defined as the zone between lines perpendicular to the SAP along the medial and lateral cortex of the pedicle in the axial section, and the superior and inferior cortex in the sagittal section without violation of the pedicle walls. The midline of MarginAx and MarginSag was defined as the safe entry point of the trajectory in the axial and sagittal planes (TrajectoryAx and TrajectorySag), respectively.MarginAx and MarginSag were 4.14 ±â€Š0.99 and 9.03 ±â€Š2.01 mm, respectively. There was a statistically significant difference in TrajectoryAx between the upper and middle, and between the upper and lower (P = .0076 in both cases), but not between the middle and lower thoracic spine (P = .066). TrajectorySag was within 1 mm at the levels of T4, T8, T11 vertebrae and at 0 mm at the other levels. Thus, the midpoint of MarginSag was within 1 mm from the SAP base.There was a constant angular relationship with the SAP and the pedicle axis; the line perpendicular to the SAP can act as a trajectory. Therefore, we suggest that the SAP might be the only accurate and safe reference for pedicle screw insertion in the thoracic spine perpendicular to the SAP using freehand technique.

[Ab] Resumo:BACKGROUND: Current retrospective evidence suggests similar clinical and superior hemodynamic outcomes of the Sorin Freedom Solo stentless aortic valve (SFS) (LivaNova PLC, London, UK) compared to the Carpentier Edwards Perimount stented aortic valve (CEP) (Edwards Lifesciences Inc., Irvine, California, USA). To date, no reports exist describing case-matched long-term outcomes and analysis for treatment of native valve endocarditis (NVE). METHODS: From 2004 through 2014, 77 consecutive patients (study group, 59.7% male, 68.9 ± 12.5 years, logEuroSCORE II 7.6 ± 12.3%) received surgical aortic valve replacement (SAVR) with the SFS. A control group of patients after SAVR with the CEP was retrieved from our database and matched to the study group regarding 15 parameters including preoperative endocarditis. Acute perioperative outcomes and follow-up data (mean follow-up time 48.7±29.8 months, 95% complete) were retrospectively analyzed. RESULTS: No differences in early mortality occurred during 30-day follow up (3/77; 3.9% vs. 4/77; 5.2%; p = 0.699). Echocardiographic findings revealed lower postprocedural transvalvular pressure gradients (max. 17.0 ± 8.2 vs. 24.5 ± 9.2 mmHg, p< 0.001/ mean pressure of 8.4 ± 4.1 vs. 13.1 ± 5.9 mmHg, p< 0.001) in the SFS group. Structural valve degeneration (SVD) (5.2% vs. 0%; p = 0.04) and valve explantation due to SVD or prosthetic valve endocarditis (PVE) (9.1% vs. 1.3%; p = 0.04) was more frequent in the SFS group. All-cause mortality during follow-up was 20.8% vs. 14.3% (p = 0.397). When patients were divided into subgroups of NVE and respective utilized bioprosthesis, the SFS presented impaired outcomes regarding mortality in NVE cases (p = 0.031). CONCLUSIONS: The hemodynamic superiority of the SFS was confirmed in this comparison. However, clinical outcomes in terms of SVD and PVE rates, as well as survival after NVE, were inferior in this study. Therefore, we are reluctant to recommend utilization of the SFS for treatment of NVE.

[Ab] Resumo:AIMS: The aim of this study was to evaluate the long-term inducible displacement of cemented tibial components ten years after total knee arthroplasty (TKA). PATIENTS AND METHODS: A total of 15 patients from a previously reported prospective trial of fixation using radiostereometric analysis (RSA) were examined at a mean of 11 years (10 to 11) postoperatively. Longitudinal supine RSA examinations were acquired at one week, one year, and two years postoperatively and at final follow-up. Weight-bearing RSA examinations were also undertaken with the operated lower limb in neutral and in maximum internal rotation positions. Maximum total point motion (MTPM) was calculated for the longitudinal and inducible displacement examinations (supine standing, standing internal rotation, and supine standing with internal rotation). RESULTS: All patients showed some inducible displacement. Two patients with radiolucent lines had greater mean standing-supine MTPM displacement (1.35; sd 0.38) compared with the remaining patients (0.68; sd 0.36). These two patients also had a greater mean longitudinal MTPM at ten years (0.64; sd 0.50) compared with the remaining patients (0.39; sd 0.13 mm). CONCLUSION: Small inducible displacements in well-fixed cemented tibial components were seen ten years postoperatively, of a similar magnitude to that which has been reported for well-fixed components one to two years postoperatively. Greater displacements were found in components with radiolucent lines. Cite this article: 2018;100-B:170-5.
