Anticoagulation therapy in patients using left ventricular assist device (LVAD) is essential to reduce hemocompatibility related adverse events (HRAEs). Vitamin K-antagonist dosage must be adapted and monitored by INR point-of-care testing (POCT) in outpatients. The study aims to determine if the frequency of INR POCT in LVAD outpatients has an influence on the quality of anticoagulation therapy (ACQ), HRAEs, and outcomes. This retrospective study included n = 48 patients who received LVAD implantation (HMII, HM3, and HVAD) between 2013 and 2017. ACQ (% of INR tests in range, PTR), outcomes and HRAEs using Kaplan-Meier curves were compared in a daily (n = 36) and 3×/week (n = 12) INR POCT group. Further, based on the achieved PTR ranging from 0-60% (poor), 61-70% (acceptable), and 71-100% (well controlled), HRAEs and outcomes were compared. Daily and 3×/week groups were similar in perioperative risk factors and INR target (p = 0.28). Freedom from any HRAE (38.9% vs. 25.0%, p = 0.44), any readmission (72.2% vs. 75.0%, p = 0.97), and 1 year survival (91.7% vs. 91.7%, p = 0.98) were comparable in both groups. The PTR was significantly higher with the daily self-assessments (73.5% vs. 68.4%, p = 0.006). Well vs. poorly controlled INR POCT patients more often had (p = 0.01) a daily POCT frequency (92%) vs. poorly controlled (54%) and significantly higher freedom from neurologic events (96.0 vs. 69.2%, p = 0.024) as well as hemorrhagic strokes (100% vs. 76.9%, p = 0.011). Well-controlled anticoagulation of LVAD outpatients is associated with less neurologic events. The frequency of INR POCT could be one of the key factors in the reduction of HRAEs, so future prospective, large-scale studies should help to clarify the effects.An increasing number of stage D heart failure patients are supported with left ventricular assist devices (LVADs), and the management of LVAD patients who require noncardiac surgery (NCS) presents unique challenges. Using the 2010-2014 National Inpatient Sample, we identified all adult cases of LVAD patients undergoing noncardiac surgeries using ICD-9-CM codes. We estimated inpatient mortality, bleeding complications, stroke, length of stay (LOS), and cost of hospitalization of the admissions related to NCS using mixed effects logistic and linear mixed regressions, respectively. A total of 30,323 patients with LVADs underwent 3,216 noncardiac surgeries (73.5% urgent) during the study period. LVAD recipients undergoing NCS had higher burden of certain comorbidities such as history of end-stage renal disease, pulmonary circulation disorders, peripheral vascular disease, and obesity. The most frequent NCS were general surgery, which included breast, endocrine, skin/burn, noncardiac transplantation, and abdominal surgeries (47.9%). In-hospital mortality was 7.7% with the highest rates observed among cases of neurologic surgeries. Vascular surgeries had the highest rates of ischemic stroke and gastrointestinal bleeding. AS2863619 solubility dmso Patients who underwent NCS had higher LOS and cost of hospitalization compared with LVAD recipients admitted to reasons other than NCS. Although bleeding complication trends have decreased, ischemic stroke and in-hospital mortality rates have increased overall during the study period. Urgent or emergency surgery was an independent predictor of mortality (OR 3.1, 95% CI 1.9-5). A significant burden of complications occurs after noncardiac surgeries in LVAD recipients.The total artificial heart (TAH) is a device that replaces the failing ventricles. There have been numerous TAHs designed over the last few decades, but the one with the largest patient experience is the SynCardia TAH-t. The 50-mL and 70-mL sizes have been approved in the United States, Europe, and Canada as a bridge to transplantation. It is indicated in patients with severe biventricular failure or structural heart issues that preclude the use of a left ventricular assist device. The majority of the patients implanted are Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) Profile 1 or 2. The one-year survival in experienced centers that have implanted over 10 TAHs is 73%. The risk factors for death include older age, need for pre-implantation dialysis, and malnutrition. The most common causes of death are multiple organ failure, usually the result of physiologic deterioration before implantation, and neurologic dysfunction. The device allows the patient to be discharged home and managed as an outpatient. Proper patient selection, the timing of intervention, patient care, and device management are essential for a suitable outcome. In addition, the CARMAT TAH is another device that will soon be studied in a clinical trial in the United States. The BiVACOR TAH is a revolutionary design utilizing electromagnetic levitation that is expected to enter a clinical trial in the next few years.Currently, the coronavirus disease 2019 (COVID-19) crisis has rapidly spread worldwide. As the earliest outbreak area of the pandemic, Wuhan, People's Republic of China, is gradually recovering to its normal state under the effective control of government authorities. Outpatient services in major hospitals are now being restored. An accumulation of asymptomatic infections is a potential risk for medical personnel, especially when there is crowding in hospitals. As the biggest center for orthopaedic patients in Wuhan, our orthopaedic outpatient department admits >300 patients per day. Optimal guidelines on how to handle this huge number of patients during the post-outbreak stage of the COVID-19 pandemic, particularly with regard to potential asymptomatic infection, are urgently needed for orthopaedic surgeons. We have developed and proposed applicable guidelines to fill this knowledge gap, including the necessary protective strategies for medical personnel in orthopaedic outpatient and inpatient wards as well as during surgery. We also have provided mental health recommendations for health-care workers. To the best of our knowledge, these guidelines are the first of their kind for orthopaedic surgeons who are slowly reestablishing medical activity following the pandemic.
