RESUMO
BACKGROUND: The COVID-19 pandemic adversely affected health care systems. Patients in need of transcatheter aortic valve replacement (TAVR) are especially susceptible to treatment delays. OBJECTIVES: This study sought to evaluate the impact of the COVID-19 pandemic on global TAVR activity. METHODS: This international registry reported monthly TAVR case volume in participating institutions prior to and during the COVID-19 pandemic (January 2018 to December 2021). Hospital-level information on public vs private, urban vs rural, and TAVR volume was collected, as was country-level information on socioeconomic status, COVID-19 incidence, and governmental public health responses. RESULTS: We included 130 centers from 61 countries, including 65,980 TAVR procedures. The first and second pandemic waves were associated with a significant reduction of 15% (P < 0.001) and 7% (P < 0.001) in monthly TAVR case volume, respectively, compared with the prepandemic period. The third pandemic wave was not associated with reduced TAVR activity. A greater reduction in TAVR activity was observed in Africa (-52%; P = 0.001), Central-South America (-33%; P < 0.001), and Asia (-29%; P < 0.001). Private hospitals (P = 0.005), urban areas (P = 0.011), low-volume centers (P = 0.002), countries with lower development (P < 0.001) and economic status (P < 0.001), higher COVID-19 incidence (P < 0.001), and more stringent public health restrictions (P < 0.001) experienced a greater reduction in TAVR activity. CONCLUSIONS: TAVR procedural volume declined substantially during the first and second waves of the COVID-19 pandemic, especially in Africa, Central-South America, and Asia. National socioeconomic status, COVID-19 incidence, and public health responses were associated with treatment delays. This information should inform public health policy in case of future global health crises.

OBJECTIVE: Antibiotic prophylaxis is recommended before invasive dental procedures to prevent endocarditis in those at high risk, but supporting data are sparse. We therefore investigated any association between invasive dental procedures and endocarditis, and any antibiotic prophylaxis effect on endocarditis incidence. SUBJECTS AND METHODS: Cohort and case-crossover studies were performed on 1,678,190 Medicaid patients with linked medical, dental, and prescription data. RESULTS: The cohort study identified increased endocarditis incidence within 30 days of invasive dental procedures in those at high risk, particularly after extractions (OR 14.17, 95% CI 5.40-52.11, p < 0.0001) or oral surgery (OR 29.98, 95% CI 9.62-119.34, p < 0.0001). Furthermore, antibiotic prophylaxis significantly reduced endocarditis incidence following invasive dental procedures (OR 0.20, 95% CI 0.06-0.53, p < 0.0001). Case-crossover analysis confirmed the association between invasive dental procedures and endocarditis in those at high risk, particularly following extractions (OR 3.74, 95% CI 2.65-5.27, p < 0.005) and oral surgery (OR 10.66, 95% CI 5.18-21.92, p < 0.0001). The number of invasive procedures, extractions, or surgical procedures needing antibiotic prophylaxis to prevent one endocarditis case was 244, 143 and 71, respectively. CONCLUSIONS: Invasive dental procedures (particularly extractions and oral surgery) were significantly associated with endocarditis in high-risk individuals, but AP significantly reduced endocarditis incidence following these procedures, thereby supporting current guideline recommendations.
RESUMO
Infective endocarditis (IE) remains a difficult condition to diagnose and treat and is an infection of high consequence for patients, causing long hospital stays, life-changing complications and high mortality. A new multidisciplinary, multiprofessional, British Society for Antimicrobial Chemotherapy (BSAC)-ledWorking Party was convened to undertake a focused systematical review of the literature and to update the previous BSAC guidelines relating delivery of services for patients with IE. A scoping exercise identified new questions concerning optimal delivery of care, and the systematic review identified 16 231 papers of which 20 met the inclusion criteria. Recommendations relating to endocarditis teams, infrastructure and support, endocarditis referral processes, patient follow-up and patient information, and governance are made as well as research recommendations. This is a report of a joint Working Party of the BSAC, British Cardiovascular Society, British Heart Valve Society, British Society of Echocardiography, Society of Cardiothoracic Surgeons of Great Britain and Ireland, British Congenital Cardiac Association and British Infection Association.

OBJECTIVE: Antibiotic prophylaxis has been recommended for patients at increased risk of infective endocarditis (IE) undergoing specific invasive procedures (IPs) despite a lack of data supporting its use. Therefore, antibiotic prophylaxis recommendations ceased in the mid-2000s for all but those at high IE risk undergoing invasive dental procedures. We aimed to quantify any association between IPs and IE. METHODS: All 14 731 IE hospital admissions in England between April 2010 and March 2016 were identified from national admissions data, and medical records were searched for IP performed during the 15-month period before IE admission. We compared the incidence of IP during the 3 months immediately before IE admission (case period) with the incidence during the preceding 12 months (control period) to determine whether the odds of developing IE were increased in the 3 months after certain IP. RESULTS: The odds of IE were increased following permanent pacemaker and defibrillator implantation (OR 1.54, 95% CI 1.27 to 1.85, p<0.001), extractions/surgical tooth removal (OR 2.14, 95% CI 1.22 to 3.76, p=0.047), upper (OR 1.58, 95% CI 1.34 to 1.85, p<0.001) and lower gastrointestinal endoscopy (OR 1.66, 95% CI 1.35 to 2.04, p<0.001) and bone marrow biopsy (OR 1.76, 95% CI 1.16 to 2.69, p=0.039). Using an alternative analysis, bronchoscopy (OR 1.33, 95% CI 1.06 to 1.68, p=0.049) and blood transfusions/red cell/plasma exchange (OR 1.2, 95% CI 1.07 to 1.35, p=0.012) were also associated with IE. CONCLUSIONS: This study identifies a significant association between specific IPs (permanent pacemaker and defibrillator implantation, dental extraction, gastrointestinal endoscopy and bronchoscopy) and subsequent IE that warrants re-evaluation of current antibiotic prophylaxis recommendations to prevent IE in high IE risk individuals.

BACKGROUND: Infective endocarditis (IE) remains a life-threatening disease with high morbidity and mortality. OBJECTIVES: To describe temporal trends in IE incidence, mortality and survival over the last 30 years. METHODS: Nineteen high-income countries (the 'EU 15+') were included. Age-standardised and sex-stratified incidence rates (ASIRs) and mortality rates (ASMRs) for IE were extracted from the Global Burden of Disease (GBD) database between 1990 and 2019, and mortality to incidence ratios (ASMIRs) were calculated. Trends were analysed using Joinpoint regression analysis. RESULTS: ASIRs were higher in males than females and increased in both sexes in all countries between 1990 and 2019. A recent steep rise in ASIRs was noted in several countries including the UK, the USA and Germany. ASMRs increased for both sexes in all countries except Finland and Austria. The largest increase in ASMR was observed in females in Italy (+246%). ASMIRs were generally higher in females compared to males, with large increases in ASMIRs (indicating worsening survival) at the end of the 20th century, but more recent stabilisation or decline across the study cohort. CONCLUSIONS: While the incidence and mortality of IE have increased over the last 30 years, recent data suggest that these trends have plateaued or reversed in most countries studied. However, a recent surge in incidence in several countries (including the USA and UK) is of concern, while unfavourable outcomes in females also merit attention. More encouragingly, this analysis provides the first indication of improving IE survival at population level, supporting recent advances in diagnosis and treatment.

BACKGROUND: During left-sided heart failure (HF), left atrial and pulmonary venous pressure increase, which may lead to pulmonary congestion. Previous cohort studies, examining participants with symptomatic HF or rheumatic heart disease, suggest a relationship between increased left atrial pressure (LAP) and fractional exhaled nitric oxide (FeNO). AIM: To examine the strength of association between FeNO and echocardiographic assessment of LAP by the E/e' ratio, to determine if FeNO could be used to identify those with elevated LAP. DESIGN & SETTING: This cross-sectional cohort study examined a subset of the OxVALVE cohort aged ≥65 years. Data collection was undertaken in primary care practices in central England. METHOD: Each participant underwent a focused cardiovascular history and clinical examination. Standard transthoracic echocardiographic (TTE) assessment was performed on all participants, with the E/e' ratio calculated to obtain a validated surrogate of LAP. FeNO was measured in 227 participants. RESULTS: FeNO was higher in males compared with females and no different in participants with asthma, chronic obstructive pulmonary disease (COPD), or those using inhaled steroids. Participants with a high E/e' (>14) were older, with a higher proportion of females than males. There was no relationship between E/e' and FeNO, either when measured as a continuous variable or in the group with high E/e'. CONCLUSION: FeNO was not found to be an accurate predictor of elevated LAP in a primary care setting.
RESUMO
BACKGROUND: Antibiotic prophylaxis (AP) before invasive dental procedures (IDPs) is recommended to prevent infective endocarditis (IE) in those at high IE risk, but there are sparse data supporting a link between IDPs and IE or AP efficacy in IE prevention. OBJECTIVES: The purpose of this study was to investigate any association between IDPs and IE, and the effectiveness of AP in reducing this. METHODS: We performed a case-crossover analysis and cohort study of the association between IDPs and IE, and AP efficacy, in 7,951,972 U.S. subjects with employer-provided Commercial/Medicare-Supplemental coverage. RESULTS: Time course studies showed that IE was most likely to occur within 4 weeks of an IDP. For those at high IE risk, case-crossover analysis demonstrated a significant temporal association between IE and IDPs in the preceding 4 weeks (OR: 2.00; 95% CI: 1.59-2.52; P = 0.002). This relationship was strongest for dental extractions (OR: 11.08; 95% CI: 7.34-16.74; P < 0.0001) and oral-surgical procedures (OR: 50.77; 95% CI: 20.79-123.98; P < 0.0001). AP was associated with a significant reduction in IE incidence following IDP (OR: 0.49; 95% CI: 0.29-0.85; P = 0.01). The cohort study confirmed the associations between IE and extractions or oral surgical procedures in those at high IE risk and the effect of AP in reducing these associations (extractions: OR: 0.13; 95% CI: 0.03-0.34; P < 0.0001; oral surgical procedures: OR: 0.09; 95% CI: 0.01-0.35; P = 0.002). CONCLUSIONS: We demonstrated a significant temporal association between IDPs (particularly extractions and oral-surgical procedures) and subsequent IE in high-IE-risk individuals, and a significant association between AP use and reduced IE incidence following these procedures. These data support the American Heart Association, and other, recommendations that those at high IE risk should receive AP before IDP.

BACKGROUND: Infective endocarditis is a heart infection with a first-year mortality rate of ≈ 30%. It has long been thought that infective endocarditis is causally associated with bloodstream seeding with oral bacteria in ≈ 40-45% of cases. This theorem led guideline committees to recommend that individuals at increased risk of infective endocarditis should receive antibiotic prophylaxis before undergoing invasive dental procedures. However, to the best of our knowledge, there has never been a clinical trial to prove the efficacy of antibiotic prophylaxis and there is no good-quality evidence to link invasive dental procedures with infective endocarditis. Many contend that oral bacteria-related infective endocarditis is more likely to result from daily activities (e.g. tooth brushing, flossing and chewing), particularly in those with poor oral hygiene. OBJECTIVE: The aim of this study was to determine if there is a temporal association between invasive dental procedures and subsequent infective endocarditis, particularly in those at high risk of infective endocarditis. DESIGN: This was a self-controlled, case-crossover design study comparing the number of invasive dental procedures in the 3 months immediately before an infective endocarditis-related hospital admission with that in the preceding 12-month control period. SETTING: The study took place in the English NHS. PARTICIPANTS: All individuals admitted to hospital with infective endocarditis between 1 April 2010 and 31 March 2016 were eligible to participate. INTERVENTIONS: This was an observational study; therefore, there was no intervention. MAIN OUTCOME MEASURE: The outcome measure was the number of invasive and non-invasive dental procedures in the months before infective endocarditis-related hospital admission. DATA SOURCES: NHS Digital provided infective endocarditis-related hospital admissions data and dental procedure data were obtained from the NHS Business Services Authority. RESULTS: The incidence rate of invasive dental procedures decreased in the 3 months before infective endocarditis-related hospital admission (incidence rate ratio 1.34, 95% confidence interval 1.13 to 1.58). Further analysis showed that this was due to loss of dental procedure data in the 2-3 weeks before any infective endocarditis-related hospital admission. LIMITATIONS: We found that urgent hospital admissions were a common cause of incomplete courses of dental treatment and, because there is no requirement to record dental procedure data for incomplete courses, this resulted in a significant loss of dental procedure data in the 2-3 weeks before infective endocarditis-related hospital admissions. The data set was also reduced because of the NHS Business Services Authority's 10-year data destruction policy, reducing the power of the study. The main consequence was a loss of dental procedure data in the critical 3-month case period of the case-crossover analysis (immediately before infective endocarditis-related hospital admission), which did not occur in earlier control periods. Part of the decline in the rate of invasive dental procedures may also be the result of the onset of illness prior to infective endocarditis-related hospital admission, and part may be due to other undefined causes. CONCLUSIONS: The loss of dental procedure data in the critical case period immediately before infective endocarditis-related hospital admission makes interpretation of the data difficult and raises uncertainty over any conclusions that can be drawn from this study. FUTURE WORK: We suggest repeating this study elsewhere using data that are unafflicted by loss of dental procedure data in the critical case period. TRIAL REGISTRATION: This trial is registered as ISRCTN11684416.

Infective endocarditis is a life-threatening infection of the heart valves. Most people are at low risk of infective endocarditis. However, those with certain cardiac conditions are at moderate risk of infective endocarditis, and those with artificial or repaired heart valves, a history of infective endocarditis and certain congenital heart conditions are at high risk of infective endocarditis. In around 4045% of cases, oral bacteria are the cause of infective endocarditis. For many years, those people at moderate or high risk of infective endocarditis were given antibiotics (antibiotic prophylaxis) before invasive dental procedures such as extractions to reduce the risk of infective endocarditis. There is no good-quality evidence, however, to support the effectiveness of antibiotic prophylaxis, or the link between invasive dental procedures and infective endocarditis. Many believe that the oral bacteria that cause infective endocarditis are more likely to enter the blood during daily activities (e.g. toothbrushing, flossing or chewing), particularly in those with poor oral hygiene, than on the rare occasions when invasive dental procedures are performed. The aim of this study was to link English NHS data on infective endocarditis-related hospital admissions and dental treatments to determine if infective endocarditis is more likely in the weeks immediately after an invasive dental procedure than at any other time. When we linked the data sets and plotted the occurrence of different dental treatments over the year before infective endocarditis-related hospital admission, we detected a problem in the way that dental data were recorded. Unfortunately, there was a failure to collect dental procedure data when courses of treatment were incomplete. As one of the most common reasons for not completing a course of treatment was emergency admission to hospital, this meant that the number of dental procedures recorded decreased in the weeks before any emergency hospital admission. We have attempted to correct for this, but the data loss has affected the data quality. Although the data suggest an association between invasive dental procedures and infective endocarditis in individuals at high risk of infective endocarditis, the certainty of this association has been weakened.

In the centenary year of the British Cardiovascular Society (BCS), this review article outlines the influence of UK cardiologists and surgeons on the field of heart valve disease, many of whom can rightly claim 'world firsts' in the field. From the description of endocarditis as we know it today at the turn of the 20th century, to the first mitral valvotomy, heart valve replacement and invention of the Ross procedure. These advances have transformed the outlook of patients with symptomatic valve disease from palliation and certain death to curative treatment and near normal life expectancy. Transcatheter aortic valve implantation (TAVI) was adopted early in the UK, and thanks to the comprehensive national database, the UK TAVI registry is one of the world's largest, contributing real-world patient data to inform clinical practice. The more recent concepts of 'Heart Valve Centres of Excellence' and specialist valve clinics have been developed by the BCS-affiliated British Heart Valve Society which continues to drive improved standards for patients with heart valve disease. The next 100 years will no doubt be equally thrilling in terms of innovation for heart valve disease, with artificial intelligence, transcatheter therapies and cutting-edge technology continuing to improve patient care and clinical outcomes.

OBJECTIVE: To define the incidence and risk factors for infective endocarditis (IE) following surgical aortic valve replacement (SAVR) and transcatheter aortic valve implantation (TAVI). METHODS: All patients who underwent first SAVR or TAVI in England between 2007 and 2016 were identified from the NICOR databases. Hospital admissions with a primary diagnosis of IE were identified by linkage with the NHS Hospital Episode Statistics database. Approval was obtained from the NHS Research Ethics Committee. RESULTS: 2057 of 91 962 patients undergoing SAVR developed IE over a median follow-up of 53.9 months-an overall incidence of 4.81 [95% CI 4.61 to 5.03] per 1000 person-years. Correspondingly, 140 of 14 195 patients undergoing TAVI developed IE over a median follow-up of 24.5 months-an overall incidence of 3.57 [95% CI 3.00 to 4.21] per 1000 person-years. The cumulative incidence of IE at 60 months was higher after SAVR than after TAVI (2.4% [95% CI 2.3 to 2.5] vs 1.5% [95% CI 1.3 to 1.8], HR 1.60, p<0.001). Across the entire cohort, SAVR remained an independent predictor of IE after multivariable adjustment. Risk factors for IE included younger age, male sex, atrial fibrillation, and dialysis. CONCLUSIONS: IE is a rare complication of SAVR and TAVI. In our population, the incidence of IE was higher after SAVR than after TAVI.
