Abstract
Introduction Streptococcus gallolyticus is an important cause of bacteremia and infective endocarditis in adults. Studies from other parts of the world have shown a strong association between S. gallolyticus bacteremia and colonic neoplasia. The profile of S. gallolyticus bacteremia is understudied in Indian population. Materials and methods We retrospectively analyzed the data of 16 patients with S. gallolyticus bacteremia obtained from microbiology registry. BacT/ALERT positive samples were inoculated into blood agar, chocolate agar, and MacConkey agar. Organisms were identified by the VITEK 2 microbial identification system, and susceptibility was done by the microbroth dilution method as per Clinical and Laboratory Standards Institute (CLSI) M100 guidelines. Clinical details were obtained from electronic medical records. Results Majority of our isolates were S. gallolyticus subspecies pasteurianus. Total 16 patients had S. gallolyticus isolated from blood over a 1 year period. The median age was 58 years (IQR: 46.5–66). Eleven were males; type II diabetes mellitus and chronic liver disease were the common comorbidities observed in our patients. None of our patients had underlying infective endocarditis or colonic malignancy. Penicillin sensitivity was 81.2% while all the isolates were susceptible to ceftriaxone. Ampicillin resistance was seen in only one of the isolates. In-hospital mortality was 12.5%. Conclusion Streptococcus gallolyticus subsp. pasteurianus is the commonest subspecies of S. gallolyticus isolated in our population. Unlike previous studies, colonic neoplasia and infective endocarditis were rare in our patients. Type II diabetes mellitus and chronic liver disease were the commonest risk factors identified in patients with S. gallolyticus bacteremia.

Abstract
Background Candida auris is an emerging yeast frequently reported as resistant to multiple antifungal drugs commonly used to treat Candida infections. This specie can colonize the patient's skin and has great ability for producing outbreaks in hospitals. C. auris is phylogenetically related to other Candida species, can be misidentified using conventional biochemical or commercial methods and requires specific technology for its identification. Case report We report the first isolate of C. auris in Cali, Colombia, from a central venous catheter in a 37-year-old patient with rheumatoid arthritis and endocarditis who did not have symptoms of sepsis. The yeast was initially misidentified as C. haemulonii using the Phoenix system and subsequently identified as C. auris by matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF MS). The broth microdilution method was used to determine the minimum inhibitory concentration; the isolate was susceptible to fluconazole, itraconazole, voriconazole and amphotericin B. Conclusions This report contributes to knowledge of the epidemiology of C. auris infections in individuals with underlying disease and describes an isolate with a behavior different from what is usually reported.

Abstract
Cotton fever is a self-limited phenomenon that occurs in IV drug users. Colloquially known to IV drug users, cotton shooting can cause cotton fever. Enterobacter asburiae endocarditis is a rare complication of cotton fever.
“Cotton fever” is described as a self-limiting illness following “cotton shooting,” the practice of injecting residual drugs extracted from previously used cotton filters. Cases of related Enterobacter agglomerans bacteremia have been described. We report the first described case of cotton fever in a patient resulting in Enterobacter asburiae endocarditis.

Abstract
OBJECTIVES In multiple countries, endovascular/disseminated Mycobacterium chimaera infections have occurred in post-cardiac surgery patients in association with contaminated, widely-distributed cardiac bypass heater-cooler devices. To contribute to long-term characterization of this recently recognized infection, we describe the clinical course of 28 patients with 3-7 years of follow-up for survivors. METHODS Identified at five hospitals in the United States 2010-2016, post-cardiac surgery patients in the cohort had growth of Mycobacterium avium complex (MAC)/M. chimaera from a sterile site or surgical wound, or a clinically compatible febrile illness with granulomatous inflammation on biopsy. Case follow-up was conducted in May 2019. RESULTS Of 28 patients, infection appeared to be localized to the sternum in four patients. Among 18 with endovascular/disseminated infection who received combination anti-mycobacterial treatment and had sufficient follow-up, 39% appeared to have controlled infection (>12 months), 56% died, and one patient is alive with relapsed bacteremia. While the number of patients is small and interpretation is limited, four (67%) of six patients who had cardiac prosthesis removal/replacement appeared to have controlled infection compared to three (25%) of 12 with retained cardiac prosthesis (p >0.14; Fisher's exact test). CONCLUSIONS Given poor response to treatment and potential for delayed relapses, post-cardiac surgery M. chimaera infection warrants aggressive treatment and long-term monitoring.

Abstract
Infectious endocarditis is a highly morbid infection that requires coordination of care across medical and surgical specialties, often through the use of a multidisciplinary team model. Multiple studies have demonstrated that such conferences can improve clinical outcomes. However, little is known about physicians' impressions of these groups. We surveyed 126 (response rate of 30%) internal medicine, infectious diseases, cardiology, and cardiac surgery providers 1 year after the implementation of an endocarditis team at the University of Michigan. Ninety-eight percent of physicians felt that the endocarditis team improved communication between specialties. Additionally, over 85% of respondents agreed that the group influenced diagnostic evaluation, reduced management errors, increased access to surgery, and decreased in-hospital mortality for endocarditis patients. These results suggest that multidisciplinary endocarditis teams are valued by physicians as a tool to improve patient care and serve an important role in increasing communication between providers.

Abstract
BACKGROUND Significant valve regurgitation is common in patients surviving native valve infective endocarditis (IE), however the associated risk of heart failure (HF) subsequent to hospital discharge after IE is sparsely described. METHODS We linked data from the East Danish Endocarditis Registry with administrative registries from 2002 to 2016 and included patients treated medically for IE who were discharged alive. Left-sided valve regurgitation was assessed by echocardiography at IE discharge and examined for longitudinal risk of HF. Multivariable adjusted Cox analysis was used to assess the associated risk of HF in patients with regurgitation (moderate or severe) compared with patients without regurgitation. RESULTS We included 192 patients, 87 patients with regurgitation at discharge (30 with aortic regurgitation and 57 with mitral regurgitation) and 105 patients without. The cumulative risk of HF at 5 years of follow-up was 28.7% in patients with regurgitation at IE discharge and 12.4% in patients without regurgitation; the corresponding multivariable adjusted HR was 3.53 (95% CI 1.72 to 7.25). We identified an increased associated risk of HF for patients with aortic regurgitation (HR=2.91, 95% CI 1.14 to 7.43) and mitral regurgitation (HR=3.95, 95% CI 1.80 to 8.67) compared with patients without regurgitation. During follow-up, 21.9% and 5.7% underwent left-sided valve surgery among patients with and without regurgitation. CONCLUSION In patients surviving IE, treated medically, we observed that severe or moderate left-sided native valve regurgitation was associated with a significantly higher risk of HF compared with patients without regurgitation at IE discharge. Close monitoring of these patients is needed to initiate surgery timely.

Abstract
INTRODUCTION Streptococcus agalactiae (group B streptococci; GBS) is an uncommon cause of bacterial meningitis in adults. METHODS We reviewed literature published between 1975 and 2018. Studies were included if they reported age, sex and outcome of patients above 16 years of age with cerebrospinal fluid culture (CSF) positive for GBS. RESULTS Sixty-seven articles describing 141 patients were included. Median age was 56 years (IQR 41-66); 52% were male. Fifty-three patients (38%) were immunocompromised and CSF leakage was reported in 9 (10%) of 88 immunocompetent patients. Sixty-two patients (44%) had extra-meningeal foci of infection, most commonly endocarditis, which occurred in 14 patients (12%). Twenty-eight patients (23%) were described as previously healthy. Forty-four (31%) of the 141 patients died, after a median duration of 5 days after admission. Death was associated with advanced age and an immunocompromised state. CONCLUSION GBS meningitis in adults mainly occurs in those with underlying conditions such as immunocompromised state, CSF leakage, and endocarditis. These conditions should be actively sought for in adults with GBS meningitis.

Abstract
Objective The treatment of active infective endocarditis (IE) presents a clinical dilemma with uncertain outcomes. This study sets out to determine the early and intermediate outcomes of patients treated surgically for active IE at an academic medical center. Methods A retrospective chart review was conducted to identify patients who underwent surgical intervention for IE at our institution from July 1st, 2011 to June 30th, 2018. In-patient records were examined to determine etiology of disease, surgical intervention type, postoperative complications, length of stay (LOS), 30-day in-hospital mortality, and 1-year survival. Results Twenty-five patients underwent surgical intervention for active IE. The average age of the patients was 47 ± 14 years old and most of the patients were male (N = 15). The majority of the patients had the mitral valve replaced (N = 10), with the remaining patients having tricuspid (N = 8) and aortic (N = 7) valve replacements. The etiology varied and included intravenous drug use (IVDU), and presence of transvenous catheters. The 30-day in-hospital mortality was 4% with 1 patient death and the 1-year survival was 80%. The average LOS was 27 days ±15 and the longest LOS was 65 days. Conclusions Surgical management of IE can be difficult and challenging however mortality can be minimized with acceptable morbidity. The most common complication was CVA. The average LOS is longer than traditional adult cardiac surgery procedures and the recurrence rate of valvular infection is not minimal especially if the underlying etiology is IVDU.

Abstract
We report a case of a 59-year-old female patient with vegetative native mitral valve endocarditis caused by Stenotrophomonas maltophilia (SM). She had hemodialysis-dependent chronic renal failure, but no immunosuppressive disease. Echocardiography showed mobile vegetation on her native mitral valve. Right femoral artery embolectomy and mitral valve replacement were performed simultaneously. She awakened from anesthesia, but she passed away due to septic shock complications. To the best of our knowledge, this was the first case in whom native mitral valve endocarditis caused by SM was observed (despite of absence of any immunosuppressive event) and needed to undergo valve replacement.

Abstract
Endocarditis is life threatening after percutaneous pulmonary valve implantation. We report a patient with acute heart failure caused by obstructive pulmonary vegetation in a Melody valve. Because of severe right ventricular dysfunction, immediate cardiac surgery was contraindicated. The patient underwent trans-catheter implantation of a covered stent to relieve obstruction. Following an initially good outcome, surgery was performed 2 weeks later. This was complicated by left main coronary artery tear and fatal bleeding. Despite covered stent was an effective bridge, surgery remains extremely challenging in such cases with important surrounding inflammation and fibrosis as well as potential proximity of coronary arteries.

A 74-year-old woman with severe aortic valve stenosis underwent aortic valve replacement with a pericardial bioprosthesis. Histological analysis of the excised valve showed dystrophic calcification associated with signs of healed infective endocarditis. Two months later, the patient died due to congestive heart failure. Autopsy revealed a bowel infarction and the presence of multiple mycotic aneurysms of the aortic root with mural thrombosis, which were unnoticed during the patient hospital stay and surgical window.

Abstract
Bioprosthetic valve thrombosis (BPVT) can occur beyond 3 months postimplantation. BPVT can reoccur after successful treatment with fibrinolysis and anticoagulation. Other forms of bioprosthetic valve dysfunction can coexist with thrombosis. Echocardiography can promptly diagnose bioprosthesis thrombosis. Management requires valve replacement, thrombolysis, or anticoagulation After BPVT long-term anticoagulation may be required.

Abstract
Background In recent years, the number of infective endocarditis (IE) cases associated with injection drug use has increased. Clinical guidelines suggest deferring surgery for IE in people who inject drugs (PWID) due to a concern for worse outcomes in comparison to non-injectors (non-PWID). We performed a systematic review and meta-analysis of long-term outcomes in PWID who underwent cardiac surgery and compared these outcomes to non-PWID. Methods We systematically searched for studies reported between 1965 and 2018. We used an algorithm to estimate individual patient data (eIPD) from Kaplan-Meier (KM) curves and combined it with published individual patient data (IPD) to analyze long-term outcomes after cardiac surgery for IE in PWID. Our primary outcome was survival. Secondary outcomes were reoperation and mortality at 30-days, one-, five-, and 10-years. Random effects Cox regression was used for estimating survival. Results We included 27 studies in the systematic review and 19 provided data (KM or IPD) for the meta-analysis. PWID were younger and more likely to have S. aureus than non-PWID. Survival at 30-days, one-, five-, and 10-years was 94.3, 81.0, 62.1, and 56.6% in PWID, respectively; and 96.4, 85.0, 70.3, and 63.4% in non-PWID. PWID had 47% greater hazard of death (HR 1.47, 95% CI, 1.05–2.05) and more than twice the hazard of reoperation (HR 2.37, 95% CI, 1.25–4.50) than non-PWID. Conclusion PWID had shorter survival that non-PWID. Implementing evidence-based interventions and testing new modalities are urgently needed to improve outcomes in PWID after cardiac surgery.

Abstract
Persons with opioid use disorder (OUD) hospitalized with severe, injection-related infections (SIRI) are frequently hospitalized for the duration of IV antibiotic treatment due to concerns regarding their eligibility for outpatient parenteral antimicrobial therapy (OPAT), which is the standard of care for prolonged IV antibiotic courses for patients without drug use. As part of a pilot study, a novel, integrated care model was developed where patients with OUD and SIRI receive addiction consultation and buprenorphine induction while hospitalized, followed by ongoing management in an outpatient clinic that combines office-based opioid treatment with buprenorphine pharmacotherapy and counseling services with OPAT. Through three illustrative case vignettes the outpatient model is described along with challenges, lessons learned and future directions.

Abstract
Background Infective endocarditis (IE) is an uncommon but life-threatening infection. It is commonly associated with diseased or damaged valves. Patients with congenital heart disease are more prone to getting IE than the general population. The typical organisms that cause IE include Staphylococcus, Coagulase-negative Staphylococcus, Streptococcus viridians and Enterococci. However, the importance of rare micro-organisms like Kocuria kristinae should not be underestimated especially when isolated from multiple blood cultures in patients suspected of IE. Case presentation We report a rare case of right-sided infective endocarditis due to K. kristinae in a young non-diabetic, non-addict female of low socioeconomic class who presented with undiagnosed fever for 1 year. She was investigated and treated for fever by several general practitioners without relief. Later on, she was diagnosed by a local cardiologist to have perimembranous ventricular septal defect with a small pulmonary valve vegetation. She was referred to a tertiary care cardiac hospital in Rawalpindi, Pakistan for further management. Transthoracic and transesophageal echocardiography confirmed IE secondary to preexisting congenital heart disease complicated with a small pulmonary vegetation. Her blood cultures yielded growth of K. kristanae, a rare micro-organism to cause IE. The patient responded to the antibiotic therapy. Conclusion Clinicians should have a high index of suspicion for K. kristanae IE as a possible cause of a prolonged fever especially in the presence of congenital heart disease. Antibiotic susceptibility is required for adequate therapy.

Abstract
Background There has been an increasing incidence of right-sided infective endocarditis (RSIE) due to the global rise of intravenous drug use (IVDU) and an increasing number of implantable cardiac electronic devices and central venous catheters. Our aim was to investigate differences in the clinical presentation, microbiological findings and prognosis of patients undergoing surgery for RSIE compared to left-sided infective endocarditis (LSIE). Methods Relevant clinical data of all 432 consecutive patients undergoing valve surgery for infective endocarditis (IE) at our institution between January 2009 and December 2018 were retrospectively analyzed. Acquired data included patients' demographic and preoperative comorbidities, manifestation of IE according to the recently modified Duke Criteria, perioperative data and relevant clinical outcomes. Results A total of 403 patients (93.3%) underwent surgery for LSIE and twenty-nine patients (6.7%) for RSIE. Eleven patients with RSIE (37.9%) showed a concomitant left-sided infection. Compared to LSIE, RSIE patients were significantly younger [47.5 (40.4-69.3) vs. 65.1 (53.7-74.6); P=0.008] and presented with less comorbidities such as hypertension (41.4% vs. 65.3%; P=0.010) and coronary artery disease (6.9% vs. 29.0%; P=0.010). Rates of IVDU (34.5% vs. 4.5%; P<0.001), human immunodeficiency virus (HIV) (10.3% vs. 1.7%; P=0.023) and hepatitis C virus (HCV) infection (24.1% vs. 5.2%; P=0.001) were greater in RSIE. The proportion of Staphylococcus aureus IE was significantly higher in RSIE compared to LSIE (37.9% vs. 21.1%; P=0.035). 30-day mortality was 6.9% after surgery for RSIE compared to 14.6% after operation for LSIE (P=0.372). Conclusions Patients undergoing surgery for RSIE compared to LSIE presented with a higher rate of pulmonary septic emboli, more Staphylococcus aureus infections and larger vegetations. Larger multicenter prospective trials are needed to provide more reliable data on the clinical profile of these patients, in order to determine optimal surgical management.

Abstract
We report a case of Pseudomonas monteilii and Acinetobacter nosocomialis endocarditis with a fatal outcome in a patient with a recent history of prosthetic aortic valve replacement. Transesophageal echocardiography and computed tomography confirmed the presence of vegetation on the prosthetic valve and aortic pseudoaneurism with an aortic root abscess. Valve cultures yielded P.monteilii and A.nosocomialis. The patient underwent surgery and received antibiotics, but his condition deteriorated and he died 44days after surgery. To our knowledge, this is the first case of P.monteilii and A.nosocomialis endocarditis reported in the literature. These organisms have been described as environmental contaminants; however, they must be considered potential pathogens, particularly in patients with prosthetic valves.

[PMID: 31279152 DOI: 10.1016/j.ijantimicag.2019.06.025] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2018] [Revised: 06/25/2019] [Accepted: 06/28/2019] [Indexed: 01/18/2023]
Abstract
Ceftaroline fosamil is a fifth-generation cephalosporin with anti-methicillin-resistant Staphylococcus aureus (MRSA) activity. It has been approved by the EMA and FDA for the treatment of adults and children with community-acquired bacterial pneumonia (CABP) and acute bacterial skin and skin structure infections (ABSSSI). However, ceftaroline fosamil has a broad spectrum of activity, and a good safety and tolerability profile, so is frequently used off-label. The aim of this systematic review was to summarize the safety and efficacy of off-label use of ceftaroline. The review was conducted according to PRISMA guidelines. MEDLINE, EMBASE and CENTRAL databases (2010-2018) were searched using as the main term ceftaroline fosamil and its synonyms in combination with names of infectious diseases of interest. A total of 21 studies with 1901 patients were included: the most common off-label indications for ceftaroline use were bacteremia (n=595), endocarditis (n=171), osteoarticular infections (n=368), hospital-acquired pneumonia (n=115) and meningitis (n=23). The most common reasons for off-label use were persistent or recurrent infection after standard treatment or non-susceptibility to vancomycin and daptomycin. Clinical success was evaluated in 933 patients, and 724 (77%) of these reached this positive outcome. Incidence of adverse events (AEs) was reported in 11 studies. In 83 (9%) cases there were AEs related to the use of ceftaroline; the most common reported AEs were nausea, vomiting, diarrhea, rash and neutropenia. The review results show that ceftaroline may be used in clinical settings other than those currently approved; however, the use of ceftaroline in these contexts deserves further investigation.

Abstract
Background Aortic valve endocarditis remains a life-threatening condition, especially in cases of periannular complications. Aorto-ventricular discontinuity associated with proximal false aneurysm represents a severe picture caused by extensive tissue disruption and is usually associated with prosthetic valve infection. Complex surgical repair is required in these cases and continues to be associated with high mortality and morbidity rates. Methods We retrieved information for 32 patients undergoing operation for infective aortic valve/prosthetic valve endocarditis complicated by pseudoaneurysm arising from aorto-ventricular discontinuity. Patients were relatively young, mostly male and most of them had a prior cardiac operation. Aortic root replacement with valve graft conduit was performed in all cases; it was associated with other procedures in seven patients: CABG (n=2), MV surgery (n=3), MV surgery + CABG (n=1) and pulmonary valve replacement (n=1). We reported and analysed patient outcomes at early and mid-term follow-up. Results Pre-discharge mortality was 22% (n=7). The postoperative course was complicated in 24 (75%) cases. Eighteen patients (56%) sustained low cardiac output resulting in multiple organ failure syndrome and death in five cases. One patient (3%) experienced a major neurologic deficit with a permanent cerebral stroke. Acute kidney injury complicated the course in 12 cases (37%), continuous renal replacement therapy was necessary in four patients (12%). Overall survival and freedom from endocarditis and reoperation at 5-year was 59% and 89%, respectively. Conclusions Patients with complicated aortic valve endocarditis presented generally in a poor preoperative state. Surgical treatment poses a non-negligible risk of postoperative mortality and morbidity but provides an acceptable survival rate and a satisfactory recovery at mid-term.

Abstract
BACKGROUND/AIMS Methicillin-resistant Staphylococcus aureus (MRSA) is highly prevalent in hospitals, and has recently emerged in the community. The impact of methicillin-resistance on mortality and medical costs for patients with S. aureus bacteremia (SAB) requires reevaluation. METHODS We searched studies with SAB or endocarditis using electronic databases including Ovid-Medline, Embase-Medline, and Cochrane Library, as well as five local databases for published studies during the period January 2000 to September 2011. RESULTS A total of 2,841 studies were identified, 62 of which involved 17,563 adult subjects and were selected as eligible. A significant increase in overall mortality associated with MRSA, compared to that with methicillin-susceptible S. aureus (MSSA), was evidenced by an odds ratio (OR) of 1.95 (95% confidence interval [CI], 1.73 to 2.21; p < 0.01). In 13 endocarditis studies, MRSA increased the risk of mortality, with an OR of 2.65 (95% CI, 1.46 to 4.80). When three studies, which compared mortality rates between CA-MRSA and CA-MSSA, were combined, the risk of methicillin-resistance increased 3.23-fold compared to MSSA (95% CI, 1.25 to 8.34). The length of hospital stay in the MRSA group was 10 days longer than that in the MSSA group (95% CI, 3.36 to 16.70). Of six studies that reported medical costs, two were included in the analysis, which estimated medical costs to be $9,954.58 (95% CI, 8,951.99 to 10,957.17). CONCLUSION MRSA is still associated with increased mortality, longer hospital stays and medical costs, compared with MSSA in SAB in studies published since the year 2000.

Abstract
BACKGROUND Optimal surgical treatment of infective tricuspid valve endocarditis in patients with intravenous drug use (IVDU) remains controversial. Tricuspid valvectomy has been proposed for infective tricuspid valve endocarditis in this patient population given the inherent social concerns. The aim of this systematic review and meta-analysis was to compare outcomes of valvectomy versus replacement for the surgical treatment of isolated infective tricuspid valve endocarditis. METHODS An electronic search was performed to identify all relevant studies published. After assessment for inclusion and exclusion criteria, 16 original studies were pooled for systematic review and meta-analysis. RESULTS There were a total of 752 patients with infective tricuspid valve endocarditis, of which 14% underwent valvectomy and 86% underwent replacement (mean follow-up 4.2 years, 95% CI, 1.9-6.4 years). The most common indications for surgical intervention were septic pulmonary embolism in the valvectomy group (74%, 95% CI, 28-95%) and persistent sepsis in the replacement group (62%, 95% CI, 31-86%). There were no differences in rates of stroke [valvectomy 4% (95% CI, 1-11%) vs. replacement 3% (95% CI, 1-16%), P=0.85] but there was increased likelihood of prolonged ventilation in those who underwent valvectomy [valvectomy 40% (95% CI, 30-51%) vs. replacement 26% (95% CI, 23-30%), P<0.01]. There were no differences in 30-day post-operative mortality [valvectomy 13% (95% CI, 5-30%) vs. replacement 7% (95% CI, 5-10%), P=0.21], post-operative right heart failure [valvectomy 27% (95% CI, 10-53%) vs. replacement 11% (95% CI, 5-25%), P=0.17] and recurrent endocarditis [valvectomy 7% (95% CI, 2-23%) vs. replacement 19% (95% CI, 12-28%), P=0.81]. Valvectomy had a higher rate of tricuspid valve reoperation [valvectomy 56% (95% CI, 15-90%) vs. initial replacement 14% (95% CI, 7-27%), P=0.06]. CONCLUSIONS Tricuspid valvectomy is an acceptable initial therapy for infective tricuspid valve endocarditis in patients with IVDU, providing a bridge to identify those who will self-select as candidates for staged valve replacement.

Use of the Valve Visualization on Echocardiography Grade Tool Improves Sensitivity and Negative Predictive Value of Transthoracic Echocardiogram for Exclusion of Native Valvular Vegetation. J Am Soc Echocardiogr 2019; 32:1551-1557.e1. [PMID: 31679901 DOI: 10.1016/j.echo.2019.08.018] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2018] [Revised: 08/05/2019] [Accepted: 08/06/2019] [Indexed: 12/14/2022]
Abstract
BACKGROUND Transesophageal echocardiography (TEE) remains the preferred test to rule out infective endocarditis (IE) but is resource intensive and carries risk. Multiple studies report low sensitivity of transthoracic echocardiography (TTE) for detection of IE; however, these studies did not account for TTE quality. We test the validity of a simple valve visualization grading tool to stratify TTEs by quality and determine whether a high-quality TTE may be used to exclude valvular vegetation and forgo the need for TEE. METHODS The Valve Visualization on Echocardiography Grade (VEG) tool scores the TTE from 0 to 10 based on leaflet visualization and valve leaflet clarity. The tool was retrospectively applied to 309 sequential patients who underwent both TTE and TEE at an academic teaching hospital between 2011 and 2015. The TEE report was the gold standard for presence or absence of vegetation. Patients with prosthetic valves and pacemaker wires were excluded. Sensitivity of TTE for detecting vegetation was calculated at each VEG score, and the optimal cutoff was identified. RESULTS A total of 309 patients were included in the analysis. Among the 216 negative TTEs, 19 (9%) had a positive TEE. The median VEG score was 4. A VEG score cutoff >6 provided optimal sensitivity and was used as the cutoff. Overall, 75 (25%) patients had a VEG score >6, and 234 (75%) had a score ≤6. Sensitivity and negative predictive value for IE were higher in the VEG >6 versus VEG ≤6 group (sensitivity 96% vs 66%, negative predictive value 97.5% vs 90%; P < .05). The false-negative rate was lower (2.5% vs 10%; P = .04) in VEG > 6 versus VEG ≤ 6 groups, respectively. CONCLUSIONS Leaflet visualization and valve leaflet clarity are important components in the TTE evaluation of patients with suspected IE. This study demonstrates that the better the valve leaflets are visualized on TTE (as represented in this population by a score >6), the higher the confidence one can have that the TTE will not be falsely negative for vegetation(s) when vegetation(s) are not noted on these TTEs. If validated in future prospective studies, this may reduce the need to perform an invasive TEE in selected patients undergoing evaluation for native valve IE.

Abstract
Compassionally reserved for inoperable patients in 2002, Transcatheter Aortic Valve Implantation has now a place almost equivalent to surgical valve replacement. The pioneering teams first succeeded in demonstrating a benefit on the mortality of extremely serious patients, while managing a learning curve that seemed unreachable without a strong partnership with cardiac surgeons. This win/win challenge enabled cardiologists to surpass the limits they did not dare to brave (management of large arterial approach, annular rupture and tamponade) and surgeons to appropriate the endovascular's culture. The technological contribution, the maturity of the teams and the expansion to less severe populations have reduced the perioperative mortality of TAVI to less than 3%. At this stage, it seemed interesting to take stock of forensic developments around this technique. After a review of the studies and the healthcare requirements, we reported and analyzed the claims received from one of the leaders of the medical insurance in France. From this feedback, attempts will be made to identify ways of improving the prevention and subsequent treatment of complications, which will undoubtedly limit the risk of subsequent complaints.
