AbstractInfective endocarditis (IE) with neurologic complications is common in patients with active IE. The most common and feared neurological complication of left-sided IE is cerebrovascular, from septic emboli causing ischemic stroke, intracranial hemorrhage (ICH), or an infectious intracranial aneurysm with or without rupture. In patients with cerebrovascular complications, valve replacement surgery is often delayed for concern of further neurological worsening. However, in circumstances when an indication for valve surgery to treat IE is present, the benefits of early surgical treatment may outweigh the potential neurologic deterioration. Furthermore, valve surgery has been associated with lower in-hospital mortality than medical therapy with intravenous antibiotics alone. Early valve surgery can be performed within 7 days of transient ischemic attack or asymptomatic stroke when medically indicated. Timing of valve surgery for IE after symptomatic medium or large symptomatic ischemic stroke or ICH remains challenging, and current data in the literature are conflicting about the risks and benefits. A delay of 2 to 4 weeks from the time of the cerebrovascular event is often recommended, balancing the risks and benefits of surgery. The range of timing of valve surgery varies depending on the clinical scenario, and is best determined by a multidisciplinary decision between cardiothoracic surgeons, cardiologists, infectious disease experts, and vascular neurologists in an experienced referral center.

Background The data on the differential impact of sex on the utilization and outcomes of valve replacement surgery for infective endocarditis are limited to single‐center and small sample size patient population. Methods and Results We utilized the National Inpatient Sample database to identify patients with a discharge diagnosis of infective endocarditis from 2004 to 2015 to assess differences in the characteristics and clinical outcomes of patients hospitalized with infective endocarditis stratified by sex. We also evaluated trends in utilization of cardiac valve replacement and individual valve replacement surgeries in women versus men over a 12‐year period, and compared in‐hospital mortality after surgical treatment in women versus men. A total of 81 942 patients were hospitalized with a primary diagnosis of infective endocarditis from January 2004 to September 2015, of whom 44.31% were women. Women were less likely to undergo overall cardiac valve replacement (6.92% versus 12.12%), aortic valve replacement (3.32% versus 8.46%), mitral valve replacement (4.60% versus 5.57%), and combined aortic and mitral valve replacement (0.85% versus 1.81%) but had similar in‐hospital mortality rates. From 2004 to 2015, the overall rates of cardiac valve replacement increased from 11.76% to 13.96% in men and 6.34% to 9.26% in women and in‐hospital mortality declined in both men and women. Among the patients undergoing valve replacement surgery, in‐hospital mortality was higher in women (9.94% versus 6.99%, P <0.001). Conclusions Despite increased utilization of valve surgery for infective endocarditis in both men and women and improving trends in mortality, we showed that there exists a treatment bias with underutilization of valve surgeries for infective endocarditis in women and demonstrated that in‐hospital mortality was higher in women undergoing valve surgery in comparison to men.

Management Protocol

This study evaluated the effectiveness of anesthesiological management in sur-gical treatment of infective endocarditis with cerebrovascular complications. The aim of the study was to decrease neurological complications and hospital mortality after surgical inter-ventions with the use of cardiopulmonary bypass in patients with infective endocarditis. The main preoperative risk factors of endocardit-associated cerebrovascular complications, which influenced the immediate results of cardiac surgery were: sepsis, systemic inflammatory response, disorders of systemic hemodynamics, high risk of recurrent cerebrovascular events, anemia and carbohydrate disorders. New anesthesiological management protocol was de-veloped and improved. Intraoperative risk factors for hospital mortality were associated with: total protein at the end of surgery less than 49 g/l; maximum blood glucose during surgery more than 10.7 mmol/l; anemia and hemodilution – hemoglobin level less than 58.8 g/l in the period of complete bypass and less than 79.4 g/l at the end of the surgery; positive water balance at the end of the operation. Determination of preoperative blood S100? protein level may be recommended to determine the prognosis of postoperative neurological complications, since the level above 0.13 µg/l was associated with postoperative neurological impairment. The implemented changes in the anesthetic management permitted to decrease neuro-logical complication rate from 22.2% to 9.6% and thirty-day mortality from 19.0% to 2.7% after surgical treatment of infective endocarditis with the use of cardiopulmonary bypass in patients with cerebrovascular complications. In order to achieve maximum effectiveness of anesthesiological management and to re-duce the level of postoperative neurological complications the optimal timing for surgery was 2–3 days after development of cerebrovascular impairment. In case of ischemic stroke in the most acute phase of the course (the first 72 hours), emergency cardiac surgery was advisable (except the cases of brain coma or total volume of myocardial infarction exceeding 31.5 cm3). In the case of ischemic stroke, more than 72 hours after the onset, and in the absence of progression of acute heart failure, the recommended timing for cardiac surgery was 4 weeks after the manifestation of cerebrovascular impairment. In the case of hemorrhagic or mixed type of neurological impairment, cardiac surgery was postponed for 1.4–2 months (since the development of the stroke).

Infective endocarditis is defined as an infection of a native or prosthetic heart valve, the endocardial surface of the heart, or an indwelling cardiac device. Among the miscellaneous emerging opportunistic bacteria that can cause infective endocarditis isGemella sanguinisthat has been reported as a cause of infective endocarditis in nine cases in the past. All of the survivors received antimicrobial therapy and underwent prosthetic valve replacement surgery while, in general, a proportion of 40–50% of the patients with infective endocarditis underwent valve surgery. Our case illustrates that valve surgery, in combination with the administration of antibiotics, is not the only therapeutic option for infective endocarditis due toGemella sanguinisand that a conservative management with prolonged administration of parenteral antibiotics under close supervision of the patient can be an option.

Infective endocarditis is an infectious and inammatory process involving endothelial lining of heart structures and valves. Cerebrovascular complications (CVCs) frequently occur in patients who are in the active stage of infective endocarditis (IE), and result from cerebral septic embolization of an endocardial vegetation. Acute stroke due to septic emboli is a particularly dreaded complication , with a frequency of 25-35%. Here we present a case of 32 year old male patient, who comes to the ER with high grade fever and palpitations since 9 days. On examination we found hyperdynamic impulse with decrescendo type systolic murmur at mitral area and we decided to do a blood workup and also requested a 2D ECHO. Blood culture and 2D ECHO showed different species of streptococci and mitral regurgitation respectively. Based on the investigations we started the patient on antibiotics, However, on the day 7 of treatment, patient developed slurring of speech and hemiparesis followed by motor aphasia. We sent the patient for brain MRI that showed acute infarct in left central semioval, left corona radiata and left perisylvian region. Acute ischemic stroke is the complication of the infective endocarditis and we started tpAalong with intravenous antibiotics after which he experienced signicant clinical improvement in few days.

Since the world was hit by novel coronavirus pandemic, so many challenges for all healthcare providers have been arisen. It is safe to say that no specialty was singled out in the matter of different complication from this viscous covid-19 situation and neurologists and neurosurgeon were no different. There are some studied reporting neurological complication associated with coronavirus infections but when it comes to life threatening and acute neurological complications such as strokes and malignant cerebral edema the data is scant. Here we are going to review the possible pathophysiology of this phenomenon, the relationship between covid-19 and acute ischemic stroke and malignant cerebral edema by taking a closer look at current data regarding this matter.

Abstract:: Acute Ischemic Stroke (AIS) is currently the most frequently reported neurological complication of Coronavirus disease 2019 (COVID-19). This article will elaborate on the clinical features of inpatients with COVID-19 and AIS and the pathophysiological mechanism of AIS under the background of COVID-19. Through a detailed search of relevant studies, we found that the incidence of AIS among COVID-19 patients varied from 0.9% to 4.6%, and AIS has been observed in many people without underlying diseases and cardiovascular risk factors as well as young people. The National Institute of Health Stroke Scale (NIHSS) score of COVID-19 patients with AIS was higher than historical AIS patients, and the proportion of large vessel occlusion (LVO) was about 64.2%. COVID-19 patients with AIS have commonly high levels of D-D dimer, fibrinogen, C-reactive protein (CRP), and erythrocyte sedimentation rate (ESR), suggesting systemic hyperinflammatory and hypercoagulable state. The pooled mortality of COVID-19 patients with AIS was 38% and the mortality of LVO patients is higher (45.9%). Compared with COVID-19-negative AIS patients in the same period in 2020 and 2019, COVID- 19 patients with AIS had a worse prognosis.

Abstract Background Infective endocarditis (IE) is associated with high mortality. Surgery may improve survival, but the intercept between benefit and harm is hard to balance and may be closely related to age. Purpose To examine the in-hospital and 90-day mortality in patients undergoing surgery for IE and to identify differences between age groups and type of valvular intervention. Methods By crosslinking nationwide Danish registries we identified patients with first-time IE undergoing surgical treatment in the period from 2000 to 2017. The study population was grouped in patients &lt;60 years, 60–75 years, and ≥75 years of age. High-risk subgroups by age and surgical valve intervention (mitral vs aortic vs mitral+aortic) during IE admission were examined. Kaplan Meier estimates was used to identify 90-day mortality by age groups and multivariable adjusted Cox proportional hazard analysis was used to examine factors associated with 90-day mortality. Results We included 1,767 patients with IE undergoing surgery, 735 patients &lt;60 years (24.1% female), 766 patients 60–75 years (25.8% female), and 266 patients &gt;75 years (36.1% female). The proportion of patients with IE undergoing surgery was 35.3%, 26.9%, and 9.1% for patients &lt;60 years, 60–75 years, and &gt;75 years, respectively. For patients with IE undergoing surgery, the in-hospital mortality was 6.4%, 13.6%, and 20.3% for patients &lt;60 years, 60–75 years, and ≥75 years of age, respectively and mortality at 90 days were 7.5%, 13.9%, and 22.3%, respectively. Factors associated with an increased risk 90-day mortality were: mitral valve surgery and a combination of mitral and aortic valve surgery as compared with isolated aortic valve surgery, patients 60–75 years and &gt;75 years as compared with patients aged &lt;60 years, prosthetic heart valve prior to IE admission, and diabetes, Figure. Patients &gt;75 years undergoing a combination of mitral and aortic valve surgery had an in-hospital mortality of 36.3%. Conclusion In patients undergoing surgery for IE, a stepwise increase in 90-day mortality was seen for age groups, highest among patients &gt;75 years with a 90-day mortality of more than 20%. Patients undergoing mitral and combined mitral and aortic valve surgery as compared to isolated aortic valve surgery were associated with a higher mortality. These findings may be of importance for the management strategy of patients with IE. Mortality risk Funding Acknowledgement Type of funding source: None

Abstract Background Managing endocarditis in intravenous drug use (IVDU) patients is challenging: unless patients successfully quit IVDU, the risk of re-infection is high. Clinicians often raise concerns with ethical and resource allocation principles when considering valve replacement surgery in this patient population. To help inform practice, we sought to determine the long-term outcomes of IVDU patients with endocarditis who underwent valve surgery in our center. Method After research ethics board approval, infective endocarditis cases managed surgically at our General Hospital between 2009 and 2018 were identified through the Cardiac Care Network. We reviewed patients' charts and included those with a history of IVDU in this study. We abstracted data on baseline characteristics, peri-operative course, short- and long-term outcomes. We report results using descriptive statistics. Results We identified 124 IVDU patients with surgically managed endocarditis. Mean age was 37 years (SD 11), 61% were females and 8% had redo surgery. During admission, 45% (n=56) of the patients had an embolic event: 63% pulmonary, 30% cerebral, 18% peripheral and 11% mesenteric. Causative organisms included Methicillin-Sensitive Staphylococcus Aureus (51%, n=63), Methicillin-Resistant Staphylococcus Aureus (15%, n=19), Streptococcus Viridans (2%, n=2), and others (31%, n=38). Emergency cardiac surgery was performed for 42% of patients (n=52). Most patients (84%) had single valve intervention: 53% tricuspid, 18% aortic and 13% mitral. Double valve interventions occurred in 15% (n=18). Overall, bioprosthetic replacement was most commonly chosen (79%, n=98). In-hospital mortality was 7% (n=8). Median length of stay in hospital was 13 days (IQR 8,21) and ICU 2 days (IQR 1,6). Mortality at longest available follow-up was 24% (n=30), with a median follow-up of 129 days (IQR 15,416). Valve reintervention rate was 11% (n=13) and readmission rate was 14% (n=17) at a median of 275 days (IQR 54,502). Conclusion Despite their critical condition, IVDU patients with endocarditis have good intra-hospital outcomes. Challenges occur after hospital discharge with loss of follow-up and high short-term mortality. IVDU relapse likely accounts for some of these issues. In-hospital and community comprehensive addiction management may improve these patients' outcomes beyond the surgical procedure.
