Right anterior mini thoracotomy for redo cardiac surgery: case series from North America and Europe.

Background: Right anterior mini thoracotomy (RAMT) for aortic valve replacement (AVR) is a minimally invasive procedure that avoids sternotomy. Herein, we report the outcomes of patients who underwent redo-cardiac via a RAMT approach for AVR. Methods: This case series reports the clinical outcomes of 14 consecutive redo operations, done in Calgary (Canada) and Gdansk (Poland) between 2020 and 2023. Primary outcomes were 30-day mortality and disabling stroke. Secondary outcomes included surgical times, hemodynamics, permanent pacemaker implantation (PPM), length of ICU and hospital stay, new post-operative atrial fibrillation (POAF), post-operative blood transfusion, incidence of acute respiratory distress syndrome (ARDS), rate of continuous renal replacement therapy (CRRT) and/or dialysis, and chest tube output in the first 12-hours after surgery. Results: Nine patients were male, and the mean age was 64.36 years. There were no deaths, while one patient had a disabling stroke postoperatively. Mean cardiopulmonary bypass and cross clamp-times were 136 min and 90 min, respectively. Three patients needed a PPM, 3 patients needed blood transfusions, and 2 developed new onset POAF. Median lengths of ICU and hospital stays were 2 and 12 days, respectively. There was no incidence of paravalvular leak greater than trace and the average transvalvular mean gradient was 12.23 mmHg. Conclusion: The number of patients requiring redo-AVR is increasing. Redo-sternotomy may not be feasible for many patients. This study suggests that the RAMT approach is a safe alternative to redo-sternotomy for patients that require an AVR.

Similar genetic profile in early and late stage urothelial tract cancer.

INTRODUCTION: Urothelial tract cancer (UTC) ranks as the tenth most prevalent cancer and holds the seventh position in terms of mortality worldwide. Despite its prevalence and mortality ranking, there are still gaps in the knowledge of the mutational landscape in patients with advanced disease who have limited therapeutic options after multiple lines of prior treatment. This study compares the genomic and transcriptomic landscape, and targeted treatment options between metastatic UTC (mUTC) patients treated with multiple lines of therapy compared to newly diagnosed, untreated Muscle Invasive Bladder Cancer (MIBC). METHODS: We compared genomic and clinical data from two cohorts: mUTC patients who received multiple lines of therapy and were referred to the Copenhagen Prospective Personalized Oncology (CoPPO) project at Rigshospitalet, University of Copenhagen. Data for MIBC UTC patients were acquired from the Cancer Genome Atlas Bladder Cancer (TCGA BLCA) cohort. Biopsies in CoPPO were performed at the time of enrollment. 523 highly important cancer-related genes (TrueSight Oncology-500 targeted sequencing panel) were used from both cohorts for comparative analysis. Analyses included RNA count data to compare predicted molecular subtypes in each cohort separately. RESULTS: Patients from the CoPPO cohort had a lower median age at first-line treatment than the TCGA BLCA cohort, with no significant gender disparity. The predominant histology was urothelial cell carcinoma in both cohorts. Genomic analysis revealed no significant difference between the top mutated genes in the two cohorts, specifically looking into DNA damage repair genes. Molecular subtyping indicated a higher frequency of neuroendocrine differentiation in the CoPPO cohort. 13% of patients in the CoPPO cohort received targeted therapy based on genomic findings, and 16% received non-targeted treatment, totaling 29% receiving CoPPO treatment (9 patients). The remaining 71% received best supportive care. Kaplan-Meier analysis showed a non-significant survival benefit for the intervention group in the CoPPO cohort. CONCLUSION: When focusing on 523 highly relevant cancer genes, the mutational profile of mUTC patients who have undergone numerous treatment lines resembles that of newly diagnosed MIBC. These alterations can be targeted, indicating the potential advantage of early genomic testing for personalized treatment within clinical trials.

Treatment of RAF1-Related Obstructive Hypertrophic Cardiomyopathy by MEK Inhibition Using Trametinib.

RASopathies cause nonsarcomeric hypertrophic cardiomyopathy via dysregulated signaling through RAS and upregulated mitogen-activated protein kinase activity. We provide the first report of the successful treatment of an adult with RAF1-associated hypertrophic cardiomyopathy using trametinib, a MEK inhibitor.

Closing the care gap: combining enhanced recovery with minimally invasive valve surgery.

PURPOSE OF REVIEW: Patients with advanced age and frailty require interventions for structural heart disease at an increasing rate. These patients typically experience higher rates of postoperative morbidity, mortality and prolonged hospital length of stay, loss of independence as well as associated increased costs to the healthcare system. Therefore, it is becoming critically important to raise awareness and develop strategies to improve clinical outcomes in the contemporary, high-risk patient population undergoing cardiacprocedures. RECENT FINDINGS: Percutaneous options for structural heart disease have dramatically improved the therapeutic options for some older, frail, high-risk patients; however, others may still require cardiac surgery. Minimally invasive techniques can reduce some of the physiologic burden experienced by patients undergoing surgery and improve recovery. Enhanced Recovery After Cardiac Surgery (ERAS Cardiac) is a comprehensive, interdisciplinary, evidence-based approach to perioperative care. It has been shown to improve recovery and patient satisfaction while reducing complications and length of stay. SUMMARY: Combining minimally invasive cardiac surgery with enhanced recovery protocols may result in improved patient outcomes for a patient population at high risk of morbidity and mortality following cardiac surgery.

Ultrasound-Guided Percutaneous Cryoneurolysis for Perioperative Analgesia Following Major Lower Extremity Amputation: A Randomized, Participant- and Observer-Masked, Sham-Controlled Pilot Study.

BACKGROUND: Extremity amputations are associated with pain in both the residual limb and the phantom limb. This pain, which is often debilitating, may be prevented by excellent perioperative pain control. Ultrasound-guided percutaneous cryoneurolysis is an analgesic modality offering pain control for weeks or months following surgery. This treatment has not been compared to the sham procedure for large nerves (e.g., femoral and sciatic) to provide preoperative analgesia. We therefore conducted a randomized, controlled pilot study to evaluate the use of this modality for the treatment of pain following amputation to (1) determine the feasibility of and optimize the study protocol for a subsequent definitive clinical trial; and (2) estimate analgesia and opioid reduction within the first postoperative weeks. METHODS: A convenience sample of seven patients undergoing lower extremity amputation were randomized to receive either active cryoneurolysis or a sham procedure targeting the sciatic and femoral nerves in a participant-masked fashion. This was a pilot study with a relatively small number of participants, and therefore the resulting data were not analyzed statistically. RESULTS: Compared to the participants who received sham treatment (n=3), those who underwent active cryoneurolysis (n=4) reported lower pain scores and decreased opioid consumption at nearly all time points between days one and 21 following amputation. CONCLUSIONS: Ultrasound-guided percutaneous cryoneurolysis of the femoral and sciatic nerves prior to lower extremity amputation appears feasible and potentially effective. The data from this pilot study may be used to power a definitive randomized clinical trial.

The Perceval Sutureless Bioprosthetic Aortic Valve: Evolution of Surgical Valve Technology.

OBJECTIVE: The surgical treatment of aortic stenosis continues to evolve, and sutureless aortic valve replacement (SUAVR) is an emerging technology. With the Perceval S (Corcym, London, UK) as the only true sutureless valve on the market, the objective of this review is to analyze the current literature on Perceval S. Focusing on valve design and deployment as well as applications of the technology for challenging pathology, clinical outcomes are assessed, including a comparison with transcatheter AVR (TAVR). METHODS: PubMed and MEDLINE were searched by 3 authors for studies analyzing SUAVR from inception to May 19, 2023. RESULTS: SUAVR facilitates minimally invasive surgery and offers an alternative strategy for patients with small aortic annuli. It also has a time-saving advantage for patients who require complex operations. SUAVR results in excellent long-term morbidity, mortality, durability, and hemodynamic function. In comparison with conventional surgical AVR (SAVR), SUAVR does have a greater risk of postoperative pacemaker implantation; however, increasing user experience and refinements in implantation technique have contributed to reductions in this outcome. SUAVR results in morbidity and mortality that is similar to rapid-deployment AVR. Midterm outcomes are superior to TAVR; however, further robust investigation into all of these comparisons is ultimately necessary. CONCLUSIONS: SUAVR bridges the gap in technology between SAVR and TAVR. The application of this exciting technology will undoubtedly grow in the coming years, during which additional investigation is paramount to optimize preoperative planning, valve deployment, and reintervention strategies.

Do all patients with history of pelvic ring injuries need a cesarean section? - A survey of orthopaedic and obstetric providers.

OBJECTIVE(S): The recommended mode of delivery following pelvic ring fractures with surgical fixation is unclear. The objective of this study was to assess expert opinions from orthopaedic surgeons and obstetrician gynecologists on their recommended delivery recommendations for pregnant individuals with a history of pelvic ring injury, and to see if there was any difference in recommendations between the two specialties, and what factors influenced recommendations. STUDY DESIGN: An electronic, web-based survey was administered to a convenience sample of orthopaedic surgeons and obstetrician gynecologists, via advertisement to members of the Orthopaedic Trauma Association (OTA), the Society for Maternal Fetal Medicine, and querying obstetrician gynecologists practicing within the Military Health System. The survey was administered from November 2021 to December 2022. A two-proportion z-test, Chi-square or Fisher's Exact Test, and descriptive statistics were used to analyze data. RESULTS: Survey respondents included 44 orthopaedic surgeons and 37 obstetricians. A total of 74 % obstetricians would recommend a trial of labor with hardware in place, while orthopaedic surgeon's recommendations varied based on the type of fixation. Forty four, 100 % of orthopaedic surgeons, recommended trial of labor if non-operative pelvic injury or unilateral posterior fixation only, 88 % recommended trial of labor if bilateral posterior fixation only, and 47.7 % for anterior trans-symphyseal plating only, 50 % for unilateral posterior and trans-symphyseal plating, and 43.2 % for bilateral posterior fixation with trans-symphyseal plating. CONCLUSIONS: The results of these surveys demonstrate the lack of consensus as to the most appropriate birth plan for patients with a history of pelvic ring injuries. Vaginal delivery following pelvic ring fracture and fixation is possible, yet these patients are significantly more likely to undergo cesarean section than the general population. As such, we recommend that women who become pregnant after operative treatment of a pelvic ring injury develop an in-depth birthing plan with their obstetrician to determine the best course.

Minimally Invasive Approaches to Mitral Valve Surgery: Where Are We Now? A Narrative Review.

Minimally invasive mitral valve surgery (MiMVS) has been increasing in prevalence. This review focuses on the approaches, clinical outcomes, and patient selection for MiMVS. There are 4 minimally invasive approaches to the mitral valve: right mini-thoracotomy (including video-assisted and fully endoscopic), robotic mitral surgery, and transapical beating heart off-pump neochordal repair. Advantages over conventional surgery include less blood loss and transfusion, improved postoperative mobility, shorter length of stay, less postoperative atrial fibrillation, fewer surgical site infections, and improved cosmesis. This range of minimally invasive techniques will continue to evolve, providing options that are tailored for different patient populations.

Partial oral versus full intravenous antibiotic treatment of endocarditis in people who inject drugs: A systematic review.

Background: Prolonged intravenous (IV) antibiotic therapy may not be optimal for people who inject drugs (PWID) with infective endocarditis (IE) due to unique social and medical needs. The role of partial IV antibiotic therapy with continued oral (PO) antibiotic therapy is unclear. Methods: A systematic review was performed using EMBASE and MEDLINE databases. Included studies compared PO to IV antibiotic treatment for IE in PWID. Results: Four studies met eligibility. Observational studies included full IV treatment groups and partial IV, partial PO treatment groups for severe injection-related infections. PWID with IE comprised 41.0%-64.7% of the study populations but outcomes specific to IE were not separately reported. All-cause 90-day readmission rates were comparable between the IV treatment group (27.9%-31.5%) and partial IV, partial PO treatment group (24.8%-32.5%). Ninety-day mortality was non-significantly different between IV treatment (4.9%-10.7%) and partial IV, partial PO treatment groups (2.4%-13.0%). One small randomized clinical trial compared IV oxacillin or vancomycin with gentamicin to PO ciprofloxacin plus rifampin. The cure rates were 91% and 90%, respectively. Conclusion: There is limited evidence comparing IV treatment to partial IV, partial PO antibiotic treatment in PWID with IE. Observational studies suggest that PO antibiotic therapy after initial IV treatment may be equivalent to full IV treatment alone within specific parameters, but randomized trials are needed to inform recommendations. Substantial clinical and social benefits for PWID and advantages for the health care system will result if PO treatment strategies with equal efficacy can be implemented.

Historique: L'antibiothérapie intraveineuse (IV) prolongée n'est peut-être pas optimale chez les utilisateurs de drogues par injection (UDI) atteints d'une endocardite infectieuse (EI) découlant de besoins médicaux et sociaux particuliers. On ne connaît pas clairement le rôle de l'antibiothérapie IV partielle conjuguée à l'antibiothérapie par voie orale (PO). Méthodologie: Les chercheurs ont procédé à une analyse systématique au moyen des bases de données EMBASE et MEDLINE. Les études incluses comparaient l'antibiothérapie PO à l'antibiothérapie IV en cas d'EI chez les UDI. Résultats: Quatre études respectaient les critères d'admissibilité. Les études observationnelles incluaient des groupes de traitement IV complets et des groupes de traitements IV et PO partiels en raison de de graves infections liées aux injections. Les UDI atteints d'une IE formaient de 41,0 % à 64,7 % de la population à l'étude, mais les résultats cliniques propres à l'IE n'étaient pas déclarés séparément. Les taux de réadmission toutes causes confondues au bout de 90 jours étaient comparables entre le groupe de traitement IV (27,9 % à 31,5 %) et le groupe de traitement IV et PO partiel (24,8 % à 32,5 %). La mortalité au bout de 90 jours n'était pas sensiblement différente entre le groupe de traitement IV (4,9 % à 10,7 %) et le groupe de traitement IV et PO partiel (2,4 % à 13,0 %). Une petite étude clinique randomisée a comparé l'oxacilline ou la gentamicine IV à la ciprofloxacine conjuguée à la rifampine PO. Les taux de guérison actuels s'élevaient à 91 % et à 90 %, respectivement. Conclusion: Les données probantes sur la comparaison entre l'antibiothérapie IV et l'antibiothérapie IV et PO partielle sont limitées chez les UDI ayant une IE. Selon les études observationnelles, l'antibiothérapie PO après un traitement IV initial pourrait équivaloir à un traitement IV complet unique selon des paramètres précis, mais des études randomisées s'imposent pour étayer les recommandations. Les UDI tireront des avantages cliniques et sociaux importants s'il est possible d'adopter des stratégies de traitement PO de même efficacité, et le système de santé en profitera également. Summary: Injection drug use significantly increases the risk of infective endocarditis, a bacterial infection of one or more heart valves. When diagnosed, infective endocarditis typically requires weeks of antibiotic therapy, often intravenous. This can amount to long hospital stays, particularly for people who inject drugs, as outpatient antibiotic therapies are often not feasible. As a result, there can be significant consequences in this population such as loss of housing, childcare, and employment, which may have already been unstable at the time of their hospital admission. As such, some people who inject drugs leave the hospital before their antibiotic course is completed. This can predispose them to redeveloping the infection and can lead to other complications including death. In the general population with infective endocarditis, the outcomes with oral antibiotics after a short course of intravenous antibiotics has been shown to be similar to a full course of intravenous treatment in some patients or in patients with specific clinical characteristics. Most of the current studies, however, do not include, or include very few people who inject drugs, so limited conclusions can be made for this population. This systematic review examines the current literature for oral compared to intravenous antibiotic treatment of infective endocarditis in people who inject drugs, in order to provide a baseline of our current understanding and advocate for more research.

Patient Characteristics and Outcomes of Geriatric Ankle Fractures: Open Fracture Is the Key Risk Factor for Complications and Functional Decline.

OBJECTIVES: To determine whether open (O) or closed (C) geriatric ankle fractures had different patient characteristics or outcomes. METHODS: . DESIGN: Retrospective cohort study. SETTING: Urban Level 1 trauma center. PATIENT SELECTION CRITERIA: Patients, age 60 years and older, who underwent operative fixation of a rotational ankle fracture (OTA/AO 44A-C) between January 2012 and September 2021. OUTCOME MEASURES AND COMPARISONS: Morbidity, defined as 90-day reoperation, 90-day readmission, or loss of mobility, as well as 1-year mortality compared between patients with closed and open fractures. RESULTS: The open cohort was older (75 years vs. 68 years; P = 0.003) but had similar Charlson comorbidity indices (4.6 O vs. 4.0 C; P = 0.323) and preinjury rates of independent ambulation (70.4% O vs. 80.9% C; P = 0.363). There were higher rates of 1-year mortality (11% vs. 0%; P < 0.001), deep infection (14.8% vs. 3.9%; P = 0.019), and loss of mobility (64.7% vs. 23.0%; P < 0.001) in the open cohort. Multivariate regression identified open fracture as an independent predictor of 90-day reoperation (OR: 20.6; P = 0.022) and loss of mobility (OR: 5.1; P = 0.011). CONCLUSIONS: Despite having comorbidities and preinjury function similar to the closed geriatric ankle fracture cohort, open ankle fracture was independently predictive of greater loss of mobility. Nearly two-thirds of geriatric patients with open ankle fractures experienced a decline in functional independence, compared with 1 in 4 of those with closed fractures. Open fracture was associated with higher rates of deep infection, reoperation, and 1-year mortality. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

The effect of spanning external fixation on entrapped structures in tibial pilon fractures.

PURPOSE: Pilon fractures are often complex injuries involving severe soft tissue injury. Studies have shown pilon fractures may entrap soft tissue structures between fracture fragments. Staged fixation of pilon fractures with spanning external fixation (SEF) is important for soft tissue rest and plays an important role in the management of these injuries. While SEF has been shown to promote soft tissue rest prior to definitive fixation, no studies have shown the effect SEF has on entrapped structures (ES). The purpose of this study was to evaluate how SEF effects ES in pilon fractures. METHODS: A retrospective review of 212 pilon fractures treated at our institution between 2010 and 2022 was performed. Patients with a CT scan pre-SEF and post-SEF met inclusion criteria. CTs were reviewed to characterize ES in pre- and post-SEF imaging. RESULTS: Of the 19 patients with ES identified on CT pre-SEF, seven (36.8%) had full release of ES post-SEF and 12 (63.2%) had no release of ES. The posterior tibial tendon was the most commonly ES and remained entrapped in 62.5% of cases. Only 25% of 43-C3 fractures had release of ES post-SEF, while 100% of 43-C1 and 43-C2 fractures demonstrated complete release of ES post-SEF. CONCLUSION: Entrapped structures in pilon fractures are likely to remain entrapped post-SEF, with only one-third of our cohort demonstrating release. In 43-C3 patterns, if ES are identified on CT pre-SEF, surgeons should consider addressing these either through mini open versus open approaches at the time of SEF as they are likely to remain entrapped post-SEF.

Fracture blisters: predictors for time to definitive fixation in pilon fractures.

PURPOSE: Fracture blisters, a common soft-tissue complication of pilon fractures, are associated with post-operative wound infections, delays in definitive fixation, and alterations in surgical plan. The purpose of this study was to (1) identify the delay in surgery attributable to the presence fracture blisters and (2) investigate the relationship of fracture blisters to comorbidities and fracture severity. METHODS: Patients with pilon fractures at an urban level 1 Trauma center from 2010 to 2021 were identified. The presence or absence of fracture blisters was noted, along with location. Demographic information, time from injury to external fixator placement, and time to definitive open reduction internal fixation (ORIF) were collected. Pilon fractures were classified according to AO/OTA guidelines using CT imaging and plain radiographs. RESULTS: 314 patients with pilon fractures were available for analysis, eighty (25%) of whom were found to have fracture blisters. Patients with fracture blisters had longer time to surgery compared to those without fracture blisters (14.2 days vs 7.9 days, p < 0.001). A greater proportion of patients with fracture blisters had AO/OTA 43C fracture patterns, compared with those without fracture blisters (71.3% vs 53.8%, p = 0.03). Fractures blisters were less likely to be localized over the posterior ankle (12%, p = 0.007). CONCLUSION: The presence of fracture blisters in pilon fractures are associated with significant delays in time to definitive fixation and higher energy fracture patterns. Fracture blisters are less commonly located over the posterior ankle which may support the implementation of a staged posterolateral approach when managing these injures.

Anterior Tibial Artery Danger Zone During Anterolateral Plate Fixation of the Distal Tibia: A 3D Computed Tomography Angiogram Modeling Study.

OBJECTIVES: The objective of this study was to define the danger zone at which the anterior tibial artery (ATA) is at risk during anterolateral plating of the distal tibia using a novel 3D computed tomography angiography (CTA) modeling technique. METHODS: 116 patients (232 lower extremities) who underwent lower extremity CTAs between April 2020 and April 2022 were identified. Those with lower extremity trauma, evidence of a previously healed tibial fracture, or poor visualization of the ATA were excluded. The remaining 150 lower extremities (92 patients) were modeled with an anterolateral distal tibia plate using Sectra IDS7 software. The distance of the ATA from bony landmarks was measured perpendicular to the level at which the vessel intersected the plate. RESULTS: The ATA intersected the plate proximally at a mean distance of 10.5 cm (95% confidence intervals, 10.2-10.9) and at a mean distance of 4.6 cm (95% confidence intervals, 4.4-4.9) distally from the central tibial plafond. The ATA intersected with the plate as far distal as hole number 1 and as proximal as hole 14 of the plate. The greatest injury risk was associated with plate holes 3-8. In this region, the artery was at risk in 46-99 percent of specimens. CONCLUSIONS: The ATA is at risk when screws are placed percutaneously in an anterolateral distal tibia plate. The artery can be as close as 4.4 cm and as far as 10.9 cm proximal to the tibial plafond when crossing the plate, correlating to a risk of injury to the ATA at plate holes 1 through 14.

Ambulation Distance Within 72 Hours after Surgical Management Is a Predictor of 90-Day Ambulatory Capacity in Elderly Patients with Hip Fracture.

INTRODUCTION: The inability to mobilize after surgical intervention for hip fractures in the elderly is established as a risk factor for greater morbidity and mortality. Previous studies have evaluated the association between the timing and distance of ambulation in the postoperative acute care phase with postoperative complications. The purpose of this study was to evaluate the association between ambulatory distance in the acute postoperative setting and ambulatory capacity at 3 months. METHODS: Patients aged 65 and older who were ambulatory at baseline and underwent surgical intervention for hip fractures from 2014 to 2019 were retrospectively reviewed. Consistent with previous literature, patients were divided into two groups: those who were able to ambulate 5 feet within 72 hours after surgical fixation (early ambulatory) and those who were not (minimally ambulatory). RESULTS: One hundred seventy patients (84 early ambulatory and 86 minimally ambulatory) were available for analysis. Using a multivariable ordinal logistic regression model, variables found to be statistically significant predictors of ambulatory status at 3 months were the ability to ambulate five feet in 72 hours (P < 0.0001), ambulatory distance at discharge (P = 0.012), and time from presentation to surgery (P = 0.039). Patients who were able to ambulate 5 feet within 72 hours had 9 times the odds of being independent ambulators rather than a lower ambulatory class (cane, walker, and nonambulatory). Pertrochanteric fractures were less likely than femoral neck fractures to independently ambulate at 3 months (17.2% vs. 42.3%; P = 0.0006). DISCUSSION: Ambulating 5 feet within 72 hours after hip fracture surgery is associated with an increased likelihood of independent ambulation at 3 months postoperatively. This simple and clear goal may be used to help enhance postoperative mobility and independence while providing a metric to guide therapy and help counsel patients and families.

Echocardiographic and clinical outcomes following beating heart NeoChord DS1000 mitral valve repair: a single centre case series.

Background: The NeoChord DS1000 system implants artificial neochords transapically, through a left mini-thoracotomy to treat degenerative mitral valve regurgitation (MR). Performed without cardiopulmonary bypass, neochord implantation and length adjustment is guided by transesophageal echocardiography. We describe imaging and clinical outcomes for a single center case series using this innovative device platform. Methods: In this prospective series, all study patients had degenerative MR and were considered for conventional mitral valve surgery. Moderate to high-risk candidates were screened for NeoChord DS1000 eligibility based on echocardiographic criteria. Study criteria included isolated posterior leaflet prolapse, leaflet-to-annulus index greater than 1.2, and coaptation length index greater than 5 mm. Patients with bileaflet prolapse, mitral annular calcification, and ischemic MR were excluded from our early experience. Results: Ten patients underwent the procedure, including 6 males and 4 females, with a mean age of 76 ± 9.5 years. All patients had severe chronic MR and normal left ventricular function. One patient required conversion to an open procedure for failure to deploy neochords with the device transapically. The median number of NeoChord sets was 3 (IQR 2.3-3.8). Immediate post-procedure (POD#0) degree of MR on echocardiography ranged from mild or less, and on postoperative day 1 (POD#1) from moderate or less. Average length of coaptation was 0.85 ± 0.21 cm and average depth of coaptation was 0.72 ± 0.15 cm. At 1-month follow-up echocardiography, MR was graded from trivial to moderate and left ventricular inner diameter dimensions decreased from an average of 5.4 ± 0.4 cm to 4.6 ± 0.3 cm. None of the patients who had successful NeoChord implantation required blood products. There was 1 perioperative stroke with no residual deficits. There were no device-related complications or serious adverse events. The median length of hospital stay was 3 (IQR 2.3-10) days. 30-day and 6-weeks postoperative mortality and readmission rates were 0%. Conclusion: We report the first Canadian case series using the NeoChord DS1000 system for off-pump, transapical, beating heart mitral valve repair, through a left mini-thoracotomy. The early surgical outcomes suggest this approach is feasible, safe, and effective in reducing MR. This novel procedure has the advantage of offering a minimally invasive, off-pump option for select patients with high surgical risk.

Review of perioperative outcomes and management of hip fracture patients on direct oral anticoagulants.

Anticoagulation use is common in elderly patients presenting with hip fractures and has been shown to delay time to surgery (TTS). Delays in operative treatment have been associated with worse outcomes in hip fracture patients. Direct oral anticoagulants (DOACs) comprise a steadily increasing proportion of all oral anticoagulation. Currently, no clear guidelines exist for perioperative management of hip fracture patients taking DOACs. DOAC use is associated with increased TTS, with delays frequently greater than 48 h from hospital presentation. Increased mortality has not been widely demonstrated in DOAC patients, despite increased TTS. Timing of surgery was not found to be associated with increased risk of transfusion or bleeding. Early surgery appears to be safe in patients taking DOACs presenting with a hip fracture, but is not currently widely accepted due to factors such as site-specific anesthesiologic protocols that periodically delay surgery. Direct oral anticoagulant use should not routinely delay surgical treatment in hip fracture patients. Surgical strategies to limit blood loss should be considered and include efficient surgical fixation, topical application of hemostatic agents, and the use of intra-operative cell salvage. Anesthesiologic strategies have utility in minimizing risk and a collaborative effort to minimize blood loss should be undertaken by the surgeon and anesthesiologist. Anesthesia team interventions include considerations regarding positioning, regional anesthesia, permissive hypotension, avoidance of hypothermia, judicious administration of blood products, and the use of systemic hemostatic agents.

Safe and Effective Aspirations and Nerve Blocks for the On-Call Orthopaedic Surgeon.

The on-call orthopaedic surgeon is faced with a wide array of orthopaedic pathology for which intra-articular aspiration, injection, and/or nerve/hematoma block may be used. Efficient use of these diagnostic and therapeutic modalities affords better patient care and a more effective on-call period. Often, these interventions are the rate limiting factor in a reduction or diagnosis. In this review, we describe joint aspirations, saline load tests, hematoma blocks, and nerve blocks in detail to include their indications, techniques, related pharmacology, pearls, and pitfalls.

Falling from new heights: Traumatic fracture burden and resource utilization after border wall height increase.

BACKGROUND: San Diego County hospitals commonly care for patients injured by falls from the United States-Mexico border. From 2018 to 2019, the height of >400 miles of an existing border wall was raised. Prior work has demonstrated a 5-fold increase in traumatic border wall fall injuries after barrier expansion. We aimed to examine the impact of a barrier height increase on fracture burden and resource use. METHODS: We performed a retrospective review of patients admitted to a level 1 trauma center from 2016 to 2021 with lower extremity or pelvic fractures sustained from a border wall fall. We defined the pre-wall group as patients admitted from 2016 to 2018 and the post-wall group as those admitted from 2019 to 2021. We collected demographic and treatment data, hospital charges, weight-bearing status at discharge, and follow-up. RESULTS: A total of 320 patients (pre-wall: 45; post-wall: 275) were admitted with 951 lower extremity fractures (pre-wall: 101; post-wall: 850) due to border wall fall. Hospital resources were utilized to a greater extent post-wall: a 537% increase in hospital days, a 776% increase in intensive care unit days, and a 468% increase in operative procedures. Overall, 86% of patients were non-weight-bearing on at least 1 lower extremity at discharge; 82% were lost to follow-up. CONCLUSION: Traumatic lower extremity fractures sustained from border wall fall rapidly rose after the wall height increase. Hospital resources were used to a greater extent. Patients were frequently discharged with weight-bearing limitations and rarely received scheduled follow-up care. Policymakers should consider the costs of caring for border fall patients, and access to follow-up should be expanded.

Direct oral anticoagulants for atrial fibrillation in early postoperative valve repair or bioprosthetic replacement.

OBJECTIVE: Despite increased use of direct oral anticoagulants (DOACs), limited evidence guides their use in the early postoperative period after bioprosthetic valve implantation in patients with atrial fibrillation. Our objective was to describe the efficacy and safety of DOACs and warfarin in the first 3 months after surgical bioprosthetic valve replacement or repair in patients with atrial fibrillation. METHODS: This was a retrospective, registry-informed cohort study of surgical patients who underwent bioprosthetic valve replacement or repair, had concomitant atrial fibrillation and received oral anticoagulation at discharge. The primary efficacy outcome was a composite of death, ischemic stroke, transient ischemic attack, and systemic embolism; the primary safety outcome was a composite of major bleeding. Key secondary outcomes were comparative analyses of primary outcomes, temporal anticoagulation prescribing patterns, and 30-day readmission rates. RESULTS: A total of 1743 patients were included. Of the 570 patients in the DOAC group, 17 (2%) met the composite efficacy outcome and 55 (10%) met the composite safety outcome. Of the 1173 patients receiving warfarin, 41 (3%) and 114 (10%) met the composite efficacy and safety outcomes, respectively. Comparative secondary analysis was not statistically significant for either the efficacy (adjusted odds ratio, 0.85; 95% confidence interval, 0.46-1.55, P = .59) or safety (adjusted odds ratio, 0.94; 95% confidence interval, 0.66-1.34, P = .76) outcomes. The 30-day readmission rates were similar between both groups. CONCLUSIONS: Our results suggest DOACs may be safe and effective alternatives to warfarin in the early postoperative period after valve repair or surgical bioprosthetic replacement. Confirmation awaits adequately powered prospective studies.
