BACKGROUND: Identification of patients with latent rheumatic heart disease by echocardiography presents a unique opportunity to prevent disease progression. Myocardial strain is a more sensitive indicator of cardiac performance than traditional measures of systolic function. OBJECTIVE: The objective of this study was to test the hypothesis that abnormalities in myocardial strain may be present in children with latent rheumatic heart disease. METHODS: Standard echocardiography images with electrocardiogram gating were obtained from Ugandan children found to have latent rheumatic heart disease as well as control subjects...

BACKGROUND: Echocardiographic screening for rheumatic heart disease in asymptomatic children may result in early diagnosis and prevent progression. Physician-led screening is not feasible in Malawi. Task shifting to mid-level providers such as clinical officers may enable more widespread screening. Hypothesis With short-course training, clinical officers can accurately screen for rheumatic heart disease using focussed echocardiography. METHODS: A total of eight clinical officers completed three half-days of didactics and 2 days of hands-on echocardiography training...

CONTEXT AND AIMS: The advent of systematic screening for rheumatic heart disease (RHD) by echocardiography in endemic regions has led to a new entity: borderline RHD. The pathogenicity and natural history of borderline RHD needs to be addressed. The aim of this study was to assess the outcomes of children detected by echocardiography as having borderline RHD. METHODS: Schoolchildren in 4th grade (i.e., aged 9-10years) who were prospectively echo-screened for RHD (2012-2014) in Nouméa, New Caledonia, were asked to participate...

BACKGROUND: The global burden of rheumatic heart disease is nearly 33 million people. Telemedicine, using cloud-server technology, provides an ideal solution for sharing images performed by non-physicians with cardiologists who are experts in rheumatic heart disease. OBJECTIVE: We describe our experience in using telemedicine to support a large rheumatic heart disease outreach screening programme in the Brazilian state of Minas Gerais. METHODS: The Programa de Rastreamento da Valvopatia Reumática (PROVAR) is a prospective cross-sectional study aimed at gathering epidemiological data on the burden of rheumatic heart disease in Minas Gerais and testing of a non-expert, telemedicine-supported model of outreach rheumatic heart disease screening...

South Africa and other areas of sub-Saharan Africa have in the past 20 years undergone rapid demographical changes, largely due to urbanisation and changes in lifestyle. This rapid change has led to a marked increase in specific cardiac conditions, such as hypertensive heart disease and coronary artery disease (with the highest prevalence in the middle-aged population), in conjunction with a range of other heart diseases, which are historically common in Africa-eg, rheumatic heart disease, cardiomyopathies, and unoperated congenital heart disease...

OBJECTIVES: Echocardiographic screening for rheumatic heart disease (RHD) can detect subclinical cases; however, adequate adherence to secondary antibiotic prophylaxis (SAP) is required to alter disease outcomes. We aimed to investigate the adherence to SAP among young people with RHD diagnosed through echocardiographic screening in Fiji and to investigate factors associated with adherence. METHODS: Patients diagnosed with RHD through echocardiographic screening in Fiji from 2006 to 2014 were included...

INTRODUCTION: Patients with elevated anti-streptolysin O (ASO) titers (ASOT) and recurrent tonsillitis episodes are known to be at higher risk for rheumatic heart disease (RHD). However, there is no data regarding prevalence of RHD in this high risk population. In this study, we aimed to screen ambulatory patients with elevated ASOT and recurrent tonsillitis episodes using echocardiography for identification of RHD. We hypothesized that prevalence of RHD is higher in this patient group compared to general population...

Rheumatic heart disease (RHD) is a chronic valvular disease resulting after severe or repetitive episodes of acute rheumatic fever (ARF), an autoimmune response to group A Streptococcus infection. RHD has been almost eliminated with improved social and health infrastructure in affluent countries while it remains a neglected disease with major cause of morbidity and mortality in many low- and middle-income countries, and resource-limited regions of high-income countries. Despite our evolving understanding of the pathogenesis of RHD, there have not been any significant advances to prevent or halt progression of disease in recent history...

A 35-year-old man presented with polyarthritis and constitutional symptoms, and a recent history of multiple tick bites and skin rash on trekking holiday. He did not respond to oral doxycycline and cephalexine for presumed Lyme's disease. Further investigation confirmed strongly positive streptococcal serology. There was absence of clinical or echocardiography evidence of heart involvement and immunological screening for inflammatory arthritis was negative. In the absence of other major Jones criteria for acute rheumatic fever, besides polyarthritis and the serological evidence of a recent streptococcal infection, a diagnosis of post-streptococcal reactive arthritis (PSRA) was also made...

When new evidence comes to light, it compels us to contemplate the implications of such evidence for health policy and practice. This article examines recent research evidence on the prevalence of asymptomatic rheumatic heart disease (RHD) in South Africa and considers the implications for the Integrated School Health Programme (ISHP). RHD is still a major burden of disease in developing countries, and elimination of this preventable condition ranks high among World Heart Federation goals. If left untreated, it becomes a chronic health condition that individuals have to cope with into their adult lives...

BACKGROUND: A reduction in the burden of rheumatic heart disease (RHD) may be possible by identifying the condition while the patient is still asymptomatic. Currently, there is much debate about whether it is appropriate to screen for the presence of rheumatic heart disease (RHD) in a symptomless population. The purpose of this study was to identify self-reported benefits and harms from the perspective of screening participants and their families. METHODS: In order to describe participant experiences and changes in behaviour post-screening, we interviewed a sample of parents/caregivers of children who were screened for the presence of RHD between 2007 and 2012 (n=276)...

BACKGROUND: Auscultation-based surveys in Ethiopia conducted in the late 1990's reported a rural prevalence of 4.6/1000 and an urban prevalence of 6.4/1000 of rheumatic heart disease (RHD). With echo-based screening, we aimed to estimate the national prevalence of RHD in school children by taking school-based samples from six regions across the country using the 2012 World Heart Federation echocardiographic criteria. PATIENTS AND METHODS: We conducted a cross-sectional echocardiographic screening of RHD in school children aged 6-18years from 28 randomly selected primary and secondary schools found in six different geographic regions of Ethiopia...

BACKGROUND: Atrial fibrillation (AF) is the most common type of sustained cardiac arrhythmia in adults, accounting for one-third of hospitalizations due to arrhythmia and related complications worldwide. Previously, rheumatic heart disease was documented as the commonest cause of AF in sub-Saharan Africa. However, due to the prevailing epidemiological transition in sub-Saharan Africa, the risk factors and ensuing complications of AF have changed and are on the increase. METHODS: This was a descriptive cross-sectional study involving 102 patients presenting with AF who were recruited from the cardiology unit of Mulago National Referral Hospital, Uganda, over 3 months...

OBJECTIVES: Atrial fibrillation (AF) is the most common sustained arrhythmia encountered in clinical practice with major public health impact mainly due to the increased risk of stroke. The recent Global Burden of Disease Study reported a lack of prevalence data from India. Our goal was to conduct a pilot study to evaluate the feasibility of assessing AF prevalence and stroke prophylaxis in an urban Indian community. METHODS: A screening camp was conducted in Nagpur, India, that evaluated adults aged ≥18 years...

BACKGROUND: Echocardiographic screening for detection of latent RHD has shown potential as a strategy to decrease the burden of disease. However, further research is needed to determine optimal implementation strategies. RHD results from a complex interplay between environment and host susceptibility. Family members share both and relatives of children with latent RHD may represent a high-risk group. The objective of this study was to use echocardiographic family screening to determine the relative risk of RHD among first-degree relatives of children with latent RHD compared to the risk in first-degree relatives of healthy peers...
