Rheumatic heart disease children risk factor

Screening with portable echocardiography has uncovered a large burden of latent rheumatic heart disease (RHD) among asymptomatic children in endemic regions, the significance of which remains unclear. This study aimed to determine the 2-year outcomes for children with latent RHD diagnosed by echocardiographic screening. Children identified with latent RHD enrolled in a biannual follow-up program. Risk factors for disease persistence and progression were examined. Of 62 children, 51 (82 %) with latent RHD had a median follow-up period of 25 months...

BACKGROUND: Echocardiographic screening for rheumatic heart disease (RHD) is becoming more widespread, but screening studies to date have used different echocardiographic definitions. The World Heart Federation has recently published new criteria for the echocardiographic diagnosis of RHD. We aimed to establish the prevalence of RHD in high-risk Indigenous Australian children using these criteria and to compare the findings with a group of Australian children at low risk for RHD. METHODS AND RESULTS: Portable echocardiography was performed on high-risk Indigenous children aged 5 to 15 years living in remote communities of northern Australia...

In children with rheumatic heart disease, conservative valve surgery is the best option whenever feasible. Surgeons must develop an attitude and interest in valve repair techniques that can be easily learned. Patients who undergo valve repair at an early age are at risk of requiring additional surgery over time. Mechanical valve replacement, nonetheless, should be reserved for situations where more conservative approaches are not feasible.

BACKGROUND: New Zealand is a developed country with high incidence of bacterial infections and postinfectious sequelae including rheumatic heart disease. We sought to describe the clinical and microbiology features of children with infective endocarditis (IE) between 1994 and 2012. METHODS: Retrospective review of patients <16 years identified from hospital records. RESULTS: In total 85 episodes occurred in 82 children and 68 (80%) were classified as Definite IE and 17 as Possible IE according to modified Duke criteria...

BACKGROUND: Heart failure in children is a common cause of morbidity and mortality, with high socio-economic burden. Its pattern varies between countries but reports from Africa are few. The data are important to inform management and prevention strategies. OBJECTIVE: To describe the pattern of congestive heart failure in a Kenyan paediatric population. METHODS: This was a retrospective study done at Kenyatta National Hospital, Nairobi Kenya...

INTRODUCTION: Few data are available about pediatric cardiovascular disease (CVD) in the Horn of Africa. The objective of this study was to describe the spectrum of CVD in children in Djibouti. METHODS: Clinical features and management of Djiboutian children between 1 month-old and 15 year-old with CVD were prospectively recorded over a two-year period in Bouffard Military Hospital in Djibouti (January 2009- December 2010). RESULTS: Clinical examination and echocardiography were performed on 156 patients: 32 of them (20%) had CVD...

SESSION TYPE: ILD Global Case Report PostersPRESENTED ON: Tuesday, October 23, 2012 at 01:30 PM - 02:30 PMINTRODUCTION: Interstitial lung disease (ILD) includes a large, heterogeneous group of mostly rare pulmonary conditions that cause derangements of the alveolar walls and loss of functional alveolar capillary units, consisting of both known and unknown causes that share common histological features. It is influenced by several factors such as host susceptibility, genetics and environmental aspects. Familial ILD is identified by verifying in two or more members of the same family...

INTRODUCTION: The diagnosis of acute rheumatic fever (RF) is based on clinical findings. However, during the chronic phase of the disease, the clinical approach is not sufficient for the follow-up of the patients and the Doppler echocardiography is a tool for the diagnosis of cardiac involvement. Prognostic variables that influence long-term outcomes are not well known. METHODS: 462 patients with RF according to Jones criteria were studied, and followed-up from the initial attack to 13...

Rheumatic heart disease (RHD) is a chronic condition characterized by fibrosis and scarring of the cardiac valves and damage to the heart muscle, leading to congestive heart failure and death. This prospective cohort study was conducted to investigate the possible relation between the levels of serum adhesion molecules and acute rheumatic fever (ARF) carditis, valvular insult severity, and residual valvular lesion after improvement of rheumatic activity. Serum levels of intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and E-selectin were assayed by enzyme-linked immunoassay (ELISA) for 50 children with ARF carditis during activity and after improvement and for 50 healthy children as control subjects...

BACKGROUND: Acute rheumatic fever (ARF) is an important cause of heart disease in Indigenous people of northern and central Australia. However, little is known about ARF in children across all Australian population groups. This national prospective study was conducted to determine patterns of disease, and populations and regions at highest risk. METHODS: The Australian Paediatric Surveillance Unit surveillance model was used to collect data on children with ARF across Australia...

INTRODUCTION: Rheumatic heart disease (RHD) remains a major contributor to morbidity and mortality in developing countries. The reported prevalence rates of RHD are highly variable and mainly attributable to differences in the sensitivity of either clinical screening to detect advanced heart disease or echocardiographic evaluation where disease is diagnosed earlier across a continuous spectrum. The clinical significance of diagnosis of subclinical RHD by echocardiographic screening and early implementation of secondary prevention has not been clearly established...

BACKGROUND: Historically, sub-Saharan Africa has had the highest prevalence rates of clinically detected rheumatic heart disease (RHD). Echocardiography-based screening improves detection of RHD in endemic regions. The newest screening guidelines (2006 World Health Organization/National Institutes of Health) have been tested across India and the Pacific Islands, but application in sub-Saharan Africa has, thus far, been limited to Mozambique. We used these guidelines to determine RHD prevalence in a large cohort of Ugandan school children, to identify risk factors for occult disease, and to assess the value of laboratory testing...

AIM:   To estimate acute rheumatic fever (ARF) incidence rates for New Zealand children and youth by ethnicity, socioeconomic deprivation and region. METHODS:   National hospital admissions with a principal diagnosis of ARF (ICD9_AM 390-392; ICD10-AM I00-I02) were obtained from routine statistics and stratified by age, ethnicity, socioeconomic deprivation index (NZDep2006) and District Health Board (DHB). RESULTS:   The mean incidence rate for ARF in 2000-2009 peaked at 9 to 12 years of age...

OBJECTIVES: The Ross procedure is the preferred aortic valve replacement (AVR) choice in small children. Nonetheless, it is a complicated surgery and there are concerns that subsequent cardiac reoperations are exceptionally complex and associated with high morbidity and mortality. We examine the surgical spectrum and report outcomes of cardiac reoperations in patients who had undergone the Ross procedure during childhood. METHODS: Records of 227 consecutive children (<18 years old) who had undergone the Ross procedure at our institution from 1991 to 2004 were reviewed...

BACKGROUND: This report reviews our 40-year experience with pediatric mitral valve replacement (MVR) with respect to mortality, valve-related morbidity, and reoperation risk factors. METHODS: From 1970 to 2010, 97 patients have undergone a total of 136 MVRs. Median age was 8 years (2 weeks to 18 years), 41 patients (42%) were less than 5 years, and 16 were infants (17%). Etiology was congenital in 65 patients (67%), rheumatic in 27 (28%), and endocarditis in 5 (5%)...

OBJECTIVE: To study the prevalence and medium term outcome of subclinical rheumatic heart disease (RHD) in India. DESIGN: Cross sectional echocardiographic screening study. SETTING: School children aged 5-15 years living in rural areas of north India. PATIENTS: A cross sectional echocardiographic screening study was carried out among 6270 randomly selected school children aged 5-15 years (10.8 ± 2.6 years; 52.7% male)...

This study investigated the predictors of chronic valvular disease in children with rheumatic carditis. The short- to mid-term follow-up records of 88 patients (mean age, 10.68 ± 2.5 years) with chronic rheumatic heart disease were reviewed. The mean follow-up period was 2.95 ± 1.4 years. Valvular involvement completely improved for 24 of the patients (27%) during the follow-up period. The multivariate logistic regression analysis found initial left ventricular dilation to be a significant independent risk factor associated with the persistence of either valvular involvement or mitral regurgitation...

OBJECTIVE: Coronary artery lesion (CAL) is a serious complication of Kawasaki disease (KD). Whether there is CAL and the severity are the most critical factors of the prognosis of KD. The incidence of KD is currently increasing year by year. KD has replaced rheumatic fever as the main entity of acquired heart disease of children. This study aimed to identify risk factors of CAL secondary to KD and take early interventions to prevent CAL or reduce its incidence. METHOD: Literature search was performed at Chinese Academic Literature Main Database, Chinese Science and Technology Periodical Database, Wanfang Periodicals and Dissertation Database, and the Chinese Biomedical Literature Database comprehensively, besides, retrospective retrieval and manual retrieval were also performed from the domestic public actions and the dissertations dating from January, 2000 to December, 2009...

UNLABELLED: Cardiovascular disease (CVD) is the leading cause of mortality worldwide and an important cause of disability. In Africa, the burden of CVD is increasing rapidly and it is now a public health concern. Epidemiological data on diseases is scarce and fragmented on the continent. AIM: To review available data on the epidemiology and pattern of heart disease in Sudan. METHODS: Data were obtained from the Sudan Household Survey (SHHS) 2006, annual health statistical reports of the Sudan Federal Ministry of Health, the STEPS survey of chronic disease risk factors in Sudan/Khartoum, and journal publications...

OBJECTIVE: We aim to report time-related outcomes following mitral valve replacement (MVR) in children and to identify factors affecting outcomes. METHODS: Clinical records from 307 children who underwent MVR between 1985 and 2004 were reviewed. Competing-risks methodology determined time-related prevalence of three mutually exclusive end-states: death, mitral reoperation and survival without subsequent MVR, and their associated risk factors. RESULTS: Mean age was 11...
