<p class="p1"><span class="s1">Mycotic aneurysm of the superior mesenteric artery (SMA) is a rare complication of infective endocarditis. We report a case with infective endocarditis involving the aortic valve complicated by multiple septic embolisms. The patient was treated with antibiotics for 6 weeks. During preparation for surgical treatment, the patient developed acute abdominal pain and was diagnosed with a ruptured SMA aneurysm, which was successfully treated with an emergency operation of aneurysm ligation. The aortic valve was replaced 17 days later and the patient recovered uneventfully. In conclusion, we present a rare case with infective endocarditis (IE) complicated by SMA aneurysm. Antibiotic treatment did not prevent the rupture of SMA aneurysm. Abdominal pain in a patient with a recent history of IE should be excluded with ruptured aneurysm.</span></p>

Abstract Background Granulomatosis with polyangiitis (GPA), formerly known as Wegener’s granulomatosis, is a systemic inflammatory process predominantly affecting upper and lower respiratory tract and kidneys. Valvular heart disease is a rare manifestation of GPA. Case summary We report two cases of acute valvular heart disease mimicking acute endocarditis caused by GPA. Both patients were middle-aged females with acute aortic valve regurgitation suggestive of possible infective endocarditis. In their recent medical history, atypical otitis and sinusitis were noted. The first patient was admitted with heart failure and the second patient because of persisting fever. Echocardiogram revealed severe aortic regurgitation with an additional structure on two cusps, suggestive of infective endocarditis in both patients. Urgent surgical replacement was performed; however, intraoperative findings did not show infective endocarditis, but severe inflammatory changes of the valve and surrounding tissue. In both patients, the valve was replaced by a prosthetic valve. Microscopic examination of the valve/myocardial biopsy showed diffuse acute and chronic inflammation with necrosis and necrotizing granulomas, compatible with GPA after infectious causes were excluded. Disease remission was obtained in both patients, in one patient with Rituximab and in the other with Glucocorticoids and Cyclophosphamide. Both had an uneventful follow-up. Discussion Granulomatosis with polyangiitis can be a rare cause of acute aortic valve regurgitation mimicking infective endocarditis with the need for surgical valve replacement. Atypical ear, nose, and throat symptoms can be a first sign of GPA. Symptom recognition is important for early diagnosis and appropriate treatment to prevent further progression of the disease.

Abstract Background The Modified Duke criteria is an important structured schematic for the diagnosis of infective endocarditis (IE). Corynebacterium jeikeium is a rare cause of IE that is often resistant to standard IE anti-microbials. We present a case of C. jeikeium IE, fulfilling the Modified Duke pathological criteria. Case summary A 50-year-old male presented with left leg peripheral vascular disease with septic changes requiring amputation. Routine echocardiography post-amputation demonstrated severe aortic valve regurgitation with vegetations that required valve replacement. Two initial blood cultures from a single venepuncture showed Streptococcus mitis which was treated with penicillin G prior to surgery. Subsequent aortic valve tissue cultured C. jeikeium with suggestive IE histological valvular changes and was successfully treated on a prolonged course of vancomycin. Discussion This is the first C. jeikeium IE case diagnosed on heart valvular tissue culture and highlights the importance for the fulfilment of the Modified Duke criteria in diagnosing left-sided IE. Mixed infection IE is rare, and this case possibly represents an unmasking of resistant C. jeikeium IE following initial treatment of penicillin G.

Abstract Background Homelessness has been a growing issue in the United States and worldwide. Bartonella quintana, the causative agent of “Trench fever”, is a well known illness among homeless populations in urban centers. While many cases of B. quintana are self limited, the disease can have advanced presentations including endocarditis. We present a short case series of three cases of B. quintana infective endocarditis (IE) in homeless individuals in Los Angeles and review the literature of cases of B. quintana IE in the homeless population. Methods Here we report three cases of B. quintana IE encountered in homeless individuals at the University of California, Los Angeles (UCLA) hospital system. A literature review was also conducted. PubMed was searched for published cases of human IE secondary to B. quintana in homeless individuals. Results All three patients were male with ages ranging from 39 to 57 years old with a history of homelessness and alcohol use. Presentations were subacute to chronic in nature consisting of constitutional symptoms as well as a range of symptoms corresponding with heart and renal failure. Each patient was found to have varying degrees of aortic insufficiency with either identified aortic valve vegetation or valvular thickening. Diagnosis was made with a combination of Bartonella serologies and whole genome sequencing PCR. All three patient’s courses were complicated by renal failure at varying points limiting the use of gentamicin for the full treatment course. Two patients ultimately underwent aortic valve replacement due to severe aortic insufficiency and completed therapy with doxycycline and rifampin. A single patient was discharged with plan to complete doxycycline and rifampin therapy however was lost to follow up. A literature review of 10 manuscripts describing 13 cases of B. quintana IE were identified. All the patients were male and the median age was 45. Six of the cases were in Europe and eight were in North America. All cases had left sided valve involvement (10 aortic, 6 mitral, 3 both valves). No cases of right sided IE were identified. Conclusion B. quintana IE should be considered in homeless patients with a clinical presentation concerning for IE. A combination of serology and PCR testing can be useful in diagnosis of this uncommon cause of infective endocarditis. Disclosures Jeffrey Klausner, MD, MPH, Nothing to disclose

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 A substantial proportion of infective endocarditis (IE) cases are complicated by local invasion. The purpose of this study was to identify patient and disease characteristics that increase the odds of local invasion in surgically treated IE patients. Methods This was a nested case-control study. All episodes of IE for patients admitted to Cleveland Clinic from January 1st, 2013 – June 30th, 2016 were identified from the Cleveland Clinic IE Registry. Patients &gt;18 years of age who underwent surgery for IE were included. Data was compiled by manual review of the Electronic Medical Record. Local invasion, defined as peri-annular extension, peri-valvular abscess, intra-cardiac fistula or pseudoaneurysm, was ascertained from the surgical operative note. Associations of selected factors with local invasion were examined in a multivariable logistic regression model. Results Among 510 patients who met inclusion criteria, 206 had local invasion. Mean age was 56 years and 369 (72 %) were male. Overall 344 (67 %) had aortic valve, 228 (45%) mitral valve, and 66 (13%) tricuspid or pulmonic valve involvement. Aortic valve involvement (OR 5.76, 95% CI 3.44 – 9.98), mechanical valve (OR 7.63, 95% CI 3.63 – 17.07), bioprosthetic valve (OR 3.20, 95% CI 1.99 – 5.19), significant paravalvular leak (OR 2.27, 95% CI 1.09 – 4.97), new atrioventricular nodal block (OR 3.05, 95% CI 1.57 – 6.09), Staphylococcus aureus infection (OR 2.11, 95% CI 1.20 – 3.76), coagulase negative staphylococcal infection (OR 2.38, 95% CI1.27 – 4.54), and non- viridans group streptococcal infection (OR 4.21, 95% CI 1.81 – 10.06) were significantly associated with local invasion. Conclusion Intra-cardiac and microorganism factors, but not comorbid conditions, are associated with local invasion in IE. Disclosures All Authors: No reported disclosures
