The World Heart Federation criteria raise the threshold of diagnosis for mild rheumatic heart disease: Three reviewers are better than one. Int J Cardiol 2019; 291:112-118. [PMID: 30851993 DOI: 10.1016/j.ijcard.2019.02.058] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2018] [Revised: 02/18/2019] [Accepted: 02/25/2019] [Indexed: 10/27/2022]
Abstract
BACKGROUND The World Heart Federation (WHF) criteria, published in 2012, provided an evidence-based guideline for the minimal diagnosis of echocardiographically-detected RHD. Primary aim of the study was to determine whether use of the WHF criteria altered the threshold for the diagnosis of echocardiographically-detected RHD compared with the previous WHO/NIH criteria. A secondary aim was to explore the utility of a three reviewer reporting system compared to a single or two reviewer reporting structure. METHODS 144 de-identified echocardiograms (RHD, congenital valvar abnormality, physiological valvar regurgitation) were independently reported using the WHF criteria by two reviewers blinded to the previous WHO/NIH diagnosis. If there was discordance between the two reviewers, a third cardiologist independently performed a tie-breaker review. RESULTS There was a 21% reduction of cases classified as RHD using the WHF criteria compared to the modified WHO/NIH criteria (68 cases compared to 86, p = 0.04). There was a 60% consensus across the different diagnostic categories with 2 reviewers, 89% majority agreement with 3 reviewers. 11% required an open label discussion. There was moderate agreement between 2 reviewers for any RHD, kappa 0.57 (CI 0.44-0.70), with no significant difference in agreement between the different categories. CONCLUSION The WHF criteria have raised the threshold for the diagnosis of RHD compared to the WHO/NIH criteria. However, inter-reporter variability of the WHF criteria is high. A three reviewer system is likely more accurate than a single or two reporter system for the diagnosis of mild RHD. This has resource implications for echocardiographic screening programmes.

Abstract
This focused review presents a critical appraisal of the World Heart Federation criteria for the echocardiographic diagnosis of rheumatic heart disease (RHD) and its performance in African RHD screening programmes. It identifies various logistical and methodological problems that negatively influence the current guideline’s performance. The authors explore novel RHD screening methodology that could address some of these shortcomings and if proven to be of merit, would require a paradigm shift in the approach to the echocardiographic diagnosis of subclinical RHD.

Abstract
OBJECTIVE We aimed to define the normal range of aortic and mitral valve thickness in healthy schoolchildren from a high prevalence rheumatic heart disease (RHD) region, using a standardised protocol for imaging and measurement. METHODS Measurements were performed in 288 children without RHD. Anterior mitral valve leaflet (AMVL) thickness measurements were performed at the midpoint and tip of the leaflet in the parasternal long axis (PSLA) in diastole, when the AMVL was approximately parallel to the ventricular septum. Thickness of the aortic valve was measured from PSLA imaging in systole when the leaflets were at maximum excursion. The right coronary and non-coronary closure lines of the aortic valve were measured in diastole in parasternal short axis (PSSA) imaging. Results were compared with 51 children with RHD classified by World Heart Federation diagnostic criteria. RESULTS In normal children, median AMVL tip thickness was 2.0 mm (IQR 1.7-2.4) and median AMVL midpoint thickness 2.0 mm (IQR 1.7-2.4). The median aortic valve thickness was 1.5 mm (IQR 1.3-1.6) in the PSLA view and 1.4 mm (IQR 1.2-1.6) in the PSSA view. The interclass correlation coefficient for the AMVL tip was 0.85 (0.71 to 0.92) and for the AMVL midpoint was 0.77 (0.54 to 0.87). CONCLUSIONS We have described a standardised method for mitral and aortic valve measurement in children which is objective and reproducible. Normal ranges of left heart valve thickness in a high prevalence RHD population are established. These results provide a reference range for school-age children in high prevalence RHD regions undergoing echocardiographic screening.

Abstract
Primarily affecting the young, rheumatic heart disease (RHD) is a neglected chronic disease commonly causing premature morbidity and mortality among the global poor. Standard clinical prevention and treatment is based on studies from the early antimicrobial era, as research investment halted soon after the virtual eradication of the disease from developed countries. The emergence of new global data on disease burden, new technologies, and a global health equity platform have revitalized interest and investment in RHD. This review surveys past and current evidence for standard RHD diagnosis and treatment, highlighting gaps in knowledge.

Abstract
In the final Jones criteria, different diagnostic criteria were established for the diagnosis of acute rheumatic fever for low risk and moderate-high risk populations. Turkey was found to be compatible with moderate-high risk populations as a result of regional screenings performed in terms of acute rheumatic fever and rheumatic heart disease. The changes in the diagnostic criteria for low-risk populations include subclinical carditis found on echocardiogram as a major criterion in addition to carditis found clinically and a body temperature of 38.5°C and above as a minor criterion. In moderate-high risk populations including Turkey, subclinical carditis found on echocardiogram in addition to clinical carditis is used as a major criterion as a new amendment. In addition, aseptic monoarthritis and polyarthralgia are used as major criteria in addition to migratory arthritis and monoarhtralgia is used as a minor criterion among joint findings. However, differentiation of subclinical carditis from physiological valve regurgitation found in healthy individuals and exclusion of other diseases involving joints when aseptic monoarthritis and polyarthralgia are used as major criteria are very important. In addition, a body temperature of 38°C and above and an erythrocyte sedimentation rate of 30 mm/h and above have been accepted as minor criteria. The diagnostic criteria for the first attack have not been changed; three minor findings have been accepted in presence of previous sterptococcal infection in addition to the old cirteria for recurrent attacks. In the final Jones criteria, it has been recommended that patients who do not fully meet the diagnostic criteria of acute rheumatic fever should be treated as acute rheumatic fever if another diagnosis is not considered and should be followed up with benzathine penicilin prophylaxis for 12 months. It has been decided that these patients be evaluated 12 months later and a decision for continuation or discontinuation of prophylaxis should be made. In countries where the disease is prevalent, it is very important for physicians to make an accurate diagnosis of acute rheumatic fever with their own logic and assessment in addition to the criteria proposed.

Abstract
BACKGROUND There is increasing use of portable echocardiography as a screening test for rheumatic heart disease (RHD). The prevalence of valvular regurgitation in healthy populations as determined using portable echocardiography has not been well defined. Minimal echocardiographic criteria for RHD have recently been clarified, but the overlap of normal and abnormal valvular regurgitation warrants further study. The aim of this study was to determine the spectrum of echocardiographic findings using portable echocardiography in children from a population with low prevalence of RHD. METHODS Screening echocardiography was conducted in 396 healthy students aged 10 to 12 years using portable echocardiographic equipment. Echocardiograms were assessed according to 2012 World Heart Federation criteria for RHD. The prevalence of physiologic valvular regurgitation was compared with that found in previous studies of children using large-platform machines. RESULTS Physiologic mitral regurgitation (MR) was present in 14.9% of subjects (95% CI, 11.7%-18.7%) and pathologic MR in 1.3% (95% CI, 0.6%-2.9%). Two percent (95% CI, 1.0%-3.9%) had physiologic aortic regurgitation, and none had pathologic aortic valve regurgitation. Physiologic tricuspid regurgitation was present in 72.7% of subjects (95% CI, 68.1%-76.9%) and physiologic pulmonary regurgitation in 89.6% (95% CI, 85.7%-91.8%). After cardiology review, no cases of definite RHD were found, but 0.5% of patients (95% CI, 0.1%-1.8%) had pathologic MR meeting World Heart Federation criteria for borderline RHD. Two percent (95% CI, 1.4%-4.6%) of the cohort had minor forms of congenital heart disease. CONCLUSIONS The spectrum of physiologic cardiac valvular regurgitation in healthy children as determined using portable echocardiography is described and is within the range of previous studies using large-platform echocardiographic equipment. The finding of two children with pathologic-grade MR, likely representing the upper limit of physiologic regurgitation, has implications for echocardiographic screening for RHD in high-prevalence regions.

Abstract
BACKGROUND Acute rheumatic fever (RF) is a common, preventable health problem in developing countries. Sporadic outbreaks and the prevalence in some indigenous populations have renewed interest in RF in developed countries also. AIMS To describe the clinical, laboratory and echocardiographic features, outcome and value of echocardiography in detecting valvular disease in RF. METHODS A prospective, cross-sectional study was conducted over 2 years. Patients under 14 years admitted to the cardiology unit of Kanti Children's Hospital, Kathmandu with RF using the Jones criteria were recruited consecutively. RESULTS The median age (range) of the 51 patients was 11 (5-14) years, the male:female ratio was 1.6:1 and 39% had a history of a sore throat. Clinical and laboratory features detected were as follows: carditis 92%, arthritis 33%, chorea 8%, subcutaneous nodules 4%, fever 51%, arthralgia 37%, elevated antistreptolysin O titre 94%, elevated CRP 78%, prolonged PR interval 45%, pericardial effusion 22% and cardiac failure 28%. In total, 36 patients (71%) complained of joint pains. A murmur on auscultation was significantly associated with underlying diseased valves confirmed by echocardiography (p=0.001). A murmur was audible in 78.4% and diseased valves were confirmed by echocardiography in 88.2%. The mitral valve was the most commonly involved valve (82%) and mitral regurgitation the commonest lesion (24%). A thickened mitral valve predicted carditis (p=0.007). Five (10%) patients died. CONCLUSION Inclusion of echocardiographic evidence of carditis and possibly arthralgia as major criteria would improve case detection.

Use of Doppler echocardiography to support the decision to discontinue secondary prophylaxis for patients with rheumatic fever and normal cardiac auscultation. Pediatr Cardiol 2013; 34:1073-80.

Abstract
Secondary prophylaxis remains the safest way to prevent or minimize heart valve damage in patients with rheumatic fever. However, criteria to determine the duration of prophylaxis have not been well established. This study aimed to evaluate the clinical and Doppler echocardiographic profile of patients with rheumatic fever and a normal clinical examination at least 5 years after the first episode and to discuss the contribution of Doppler echocardiography in supporting the decision to discontinue secondary prophylaxis. An observational longitudinal study analyzing 183 patients with rheumatic fever and a normal clinical examination 5 years or more after the initial attack was conducted. The patients underwent Doppler echocardiography to study the severity of mitral or aortic valvular disease. Of the 183 patients, 77 (42 %) had clinical carditis. Subclinical chronic heart disease occurred for 79 % of the patients with previous clinical carditis and for 25 % of the patients without clinical carditis. Of the 35 patients with previous clinical carditis who were in the period of discontinued prophylaxis, residual valvular heart disease was observed in all, whereas of the 62 patients without clinical carditis, only 27 % showed residual valvular heart disease. Considering Doppler echocardiographic criteria, prophylaxis would be continued for 13 (34 %) of the patients with previous clinical carditis and for only 2 (3 %) of those without clinical carditis. Return of cardiac auscultation to normal is not always accompanied by return of Doppler echocardiographic findings to normal. Criteria regarding Doppler echocardiographic findings and valve morphology should be evaluated by the time secondary prophylaxis is discontinued. However, further studies are needed to demonstrate whether prolonged prophylaxis provides any benefit to patients with persistent echocardiographic findings.

Abstract
Over the past 5 years, the advent of echocardiographic screening for rheumatic heart disease (RHD) has revealed a higher RHD burden than previously thought. In light of this global experience, the development of new international echocardiographic guidelines that address the full spectrum of the rheumatic disease process is opportune. Systematic differences in the reporting of and diagnostic approach to RHD exist, reflecting differences in local experience and disease patterns. The World Heart Federation echocardiographic criteria for RHD have, therefore, been developed and are formulated on the basis of the best available evidence. Three categories are defined on the basis of assessment by 2D, continuous-wave, and color-Doppler echocardiography: 'definite RHD', 'borderline RHD', and 'normal'. Four subcategories of 'definite RHD' and three subcategories of 'borderline RHD' exist, to reflect the various disease patterns. The morphological features of RHD and the criteria for pathological mitral and aortic regurgitation are also defined. The criteria are modified for those aged over 20 years on the basis of the available evidence. The standardized criteria aim to permit rapid and consistent identification of individuals with RHD without a clear history of acute rheumatic fever and hence allow enrollment into secondary prophylaxis programs. However, important unanswered questions remain about the importance of subclinical disease (borderline or definite RHD on echocardiography without a clinical pathological murmur), and about the practicalities of implementing screening programs. These standardized criteria will help enable new studies to be designed to evaluate the role of echocardiographic screening in RHD control.

Abstract
OBJECTIVES The annual incidence of ARF ranges from 5 to 51/100, 000 population worldwide in the 5- to 15-year age group. In the past, there was a decline in the incidence of ARF; however, focal outbreaks have been reported. This study evaluated the incidence of ARF in 2007-08 in a region of a developed country compared with the previous decade. METHODS A retrospective review of all admission records for ARF in Trieste between January 2007 and December 2008 was undertaken. The diagnosis of ARF was established by the Jones criteria according to the 1992 revision. RESULTS Between January 2007 and December 2008: 13 cases of ARF were recorded, 11 females and 2 males. The estimated incidence was 23 and 27/100, 000 population new cases each year, respectively, in the 5- to 15-year age group. Migratory polyarthritis occurred in 6/13, chorea in 7/13 and clinical carditis in 5/13 cases. Five out of 13 patients had only echocardiographic abnormalities, with no clinical cardiac manifestations. Another two patients did not fulfil diagnostic criteria for ARF, presenting with only three minor criteria, but they revealed silent carditis at echocardiography evaluation. During the follow-up, in one case the carditis receded and in the other it significantly improved. CONCLUSIONS Our experience underlines that ARF has not yet disappeared in industrialized countries. We observed a high incidence of chorea, always associated with mild carditis. Echocardiographic assessment should be routinely performed in all patients with suspected ARF in order to identify those subclinical cases of valvulitis that would otherwise pass undiagnosed without receiving proper prophylaxis.

Abstract
Acute rheumatic fever and rheumatic heart disease are diseases of socioeconomic disadvantage. These diseases are common in developing countries and in Indigenous populations in industrialized countries. Clinicians who work with Indigenous populations need to maintain a high index of suspicion for the potential diagnosis of acute rheumatic fever, particularly in patients presenting with joint pain. Inexpensive medicines, such as aspirin, are the mainstay of symptomatic treatment of rheumatic fever; however, antiinflammatory treatment has no effect on the long-term rate of progression or severity of chronic valvular disease. The current focus of global efforts at prevention of rheumatic heart disease is on secondary prevention (regular administration of penicillin to prevent recurrent rheumatic fever), although primary prevention (timely treatment of streptococcal pharyngitis to prevent rheumatic fever) is also important in populations in which it is feasible.

Abstract
BACKGROUND Acute rheumatic fever (ARF) and its sequela, rheumatic heart disease is the commonest cause of childhood cardiac morbidity globally. The current approach to the prevention of a primary attack of rheumatic fever in children using oral medication for streptococcal pharyngitis is poorly supported. The efficacy of injectable penicillin, in high rheumatic fever incidence military environments is indisputable. OBJECTIVE To evaluate school-based control of rheumatic fever in an endemic area. METHODS Fifty-three schools ( approximately 22,000 students) from a rheumatic fever high incidence setting ( approximately 60/100,000) in Auckland, New Zealand were randomized. The control group received routine general practice care. The intervention was a school-based sore throat clinic program with free nurse-observed oral penicillin treatment of group A streptococcal pharyngitis. The outcome measure was ARF in any child attending a study school. Analysis A defined ARF cases using criteria derived from Jones Criteria 1965 (definite) and 1956 (probable) with more precise definitions. Analysis B was based on 1992 Jones criteria but also included echocardiography to determine definite cases. RESULTS In Analysis A, 24 (55/100,000) cases occurred in clinic schools and 29 (67/100,000) in nonclinic schools, a 21% reduction when adjusted for demography and study design (P = 0.47). Analysis B revealed a 28% reduction 26 (59/100,000) and 33 (77/100,000) cases, respectively (P = 0.27). CONCLUSION This study involving 86,874 person-years showed a nonsignificant reduction in the school-based sore throat clinic programs.

Abstract
Rheumatic heart disease is the only residual morbidity, and the sole cause of mortality, from rheumatic fever. Echocardiography is ideally suited to confirm and follow the course of rheumatic heart disease. Additionally, both minimal valvar pathology in children, and extensive valvar pathology in adults, may not cause a murmur and can be detected only by echocardiography. Whenever possible, echocardiography should be routinely employed for management of patients with rheumatic fever or suspected rheumatic fever.

Abstract
BACKGROUND There is a great need for echocardiographic criterions for accurate diagnosis of carditis in acute rheumatic fever. AIM To test the efficacy of proposed echocardiographic criterions for the diagnosis of carditis. MATERIALS AND METHODS We studied 333 patients suspected of having acute rheumatic fever, undertaking detailed clinical examination, laboratory tests and meticulous echocardiography in each case. We used previously established echocardiographic criterions for the diagnosis of carditis and subclinical valvitis. In 220 cases (66.06%), both the echo criterions, and the Jones' criterions, gave positive results. In 52 cases (15.61%), we found evidence of subclinical carditis, in that clinically no murmur was heard, meaning the Jones' criterions were negative, but the echocardiographic evaluation was positive. In 4 patients clinically diagnosed as having carditis, the Jones' criterions were positive, but echocardiographic evaluation showed them to have congenitally malformed hearts. In another 57 cases (17.11%), the Jones' criterions were negative, as were the results of echocardiographic evaluation. These patients were taken as control subjects. On this basis, the echocardiographic criterions had sensitivity of 81% and specificity of 93%. CONCLUSION Using our echocardiographic criterions, it is possible to make a precise diagnosis of carditis or subclinical valvitis. Hence, echocardiography should, in future, be included as a major criterion in the Jones' system.

Evaluation of a screening protocol using auscultation and portable echocardiography to detect asymptomatic rheumatic heart disease in Tongan schoolchildren. ACTA ACUST UNITED AC 2008; 5:411-7. [PMID: 18398402 DOI: 10.1038/ncpcardio1185] [Citation(s) in RCA: 122] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2007] [Accepted: 11/28/2007] [Indexed: 11/09/2022]
Abstract
BACKGROUND Rheumatic heart disease (RHD) is an important problem in developing countries; however, many cases are detected only when the disease has progressed to cardiac failure. Screening can detect cases earlier, but there are no screening guidelines. METHODS We performed a cross-sectional screening study in Tonga among 5,053 primary school children, in whom auscultation followed by echocardiography of those with heart murmurs were used to identify RHD. We also analyzed whether a three-stage screening protocol of auscultation performed by a medical student to detect any heart murmur, second-stage auscultation performed by a local pediatrician to differentiate pathological from innocent murmurs and echocardiography of those with pathological murmurs altered outcomes. RESULTS The prevalence of definite RHD was 33.2 per 1,000. The prevalence of RHD increased significantly with age, peaking at 42.6 per 1,000 in children aged 10-12 years. Most valve lesions (91 [54%] of 169) were mild. Auscultation to detect pathological murmurs was poorly sensitive (46.4%), and the finding of any murmur on auscultation did not affect the likelihood of detecting pathology on echocardiography. The finding of a pathological murmur did significantly increase the likelihood of detecting pathology on echocardiography, but still missed 54% of those with pathology (mainly RHD) detected on echocardiography. CONCLUSIONS Screening is a useful method for detecting asymptomatic RHD in regions of high prevalence and we report a high echocardiographically confirmed prevalence. The most appropriate screening strategy remains to be confirmed, however, and implementation will depend on the availability of echocardiography and trained staff.

Abstract
BACKGROUND Epidemiologic studies of the prevalence of rheumatic heart disease have used clinical screening with echocardiographic confirmation of suspected cases. We hypothesized that echocardiographic screening of all surveyed children would show a significantly higher prevalence of rheumatic heart disease. METHODS Randomly selected schoolchildren from 6 through 17 years of age in Cambodia and Mozambique were screened for rheumatic heart disease according to standard clinical and echocardiographic criteria. RESULTS Clinical examination detected rheumatic heart disease that was confirmed by echocardiography in 8 of 3677 children in Cambodia and 5 of 2170 children in Mozambique; the corresponding prevalence rates and 95% confidence intervals (CIs) were 2.2 cases per 1000 (95% CI, 0.7 to 3.7) for Cambodia and 2.3 cases per 1000 (95% CI, 0.3 to 4.3) for Mozambique. In contrast, echocardiographic screening detected 79 cases of rheumatic heart disease in Cambodia and 66 cases in Mozambique, corresponding to prevalence rates of 21.5 cases per 1000 (95% CI, 16.8 to 26.2) and 30.4 cases per 1000 (95% CI, 23.2 to 37.6), respectively. The mitral valve was involved in the great majority of cases (87.3% in Cambodia and 98.4% in Mozambique). CONCLUSIONS Systematic screening with echocardiography, as compared with clinical screening, reveals a much higher prevalence of rheumatic heart disease (approximately 10 times as great). Since rheumatic heart disease frequently has devastating clinical consequences and secondary prevention may be effective after accurate identification of early cases, these results have important public health implications.

Abstract
OBJECTIVE Subclinical carditis (SCC)--pathological valvular regurgitation detected on echocardiography that is not evident clinically--has been reported in acute rheumatic fever (ARF), but its significance is unknown. We aimed to review the existing literature on the prevalence and outcome of SCC in ARF. METHODS We conducted a systematic literature review using MEDLINE. RESULTS Prevalences of SCC in ARF ranged from 0% (in one study only) to 53% in 23 articles. The weighted pooled prevalence of SCC in ARF was 16.8% (95%CI 11.9 to 21.6). This increased slightly to 18.1% (95%CI 11.1 to 25.2) by analysing only the 10 studies that applied full World Health Organization criteria for SCC diagnosis. The weighted pooled prevalence of persistence or deterioration of SCC 3 to 23 months after ARF diagnosis was 44.7% (95%CI 19.3 to 70.2) from 11 articles. CONCLUSION SCC is relatively common in ARF. Although some studies suggest that SCC lesions may persist or deteriorate, the available data are insufficient and of poor quality, so no confident conclusions can be drawn about the prognosis of SCC. Until better studies are conducted, clinicians will have to make management decisions that are not evidence-based. These decisions will have important practical implications for the use of echocardiography acutely and during follow-up, diagnosis of ARF, and duration of secondary prophylaxis in patients with SCC.

Abstract
OBJECTIVES Acute rheumatic fever and its sequel, rheumatic heart disease, is a major problem in children, adolescents and young adults. Despite the widespread application of the Jones criterions, carditis is either underdiagnosed or overdiagnosed. Echocardiography is rarely used optimally for precise diagnosis. The objective of our study, therefore, was to define the potential role of echocardiography in detecting carditis in the setting of acute rheumatic fever. MATERIALS AND METHODS We performed echocardiography in 452 consecutive patients with acute rheumatic fever, clinically diagnosed by the strict Jones criterions, using the patients as part of a multi-centric and double blinded prospective study. RESULTS Of our 452 patients, 230 were males, and 222 were females. The youngest was aged 1 year 11 months, while the oldest was a 51-year-old female. Out of the 452 cases of acute rheumatic fever, 239 patients (52.8%) had arthritis. Out of 164 cases of clinically diagnosed carditis, only 141 cases had echocardiographic evidence of carditis (85.97%). The remaining 23 patients (14%) had functional murmurs, tachycardia, or anaemia. Of the patients, 2 also had congenitally malformed hearts. Of 40 patients with rheumatic chorea, 28 (70%) had echocardiographic evidence of carditis or valvitis. Polyarthralgia was seen in 213 cases (47.12%), from which only 38 patients (17.8%) had carditis clinically, albeit that 88 patients (41.3%) showed echocardiographic evidence of subclinical carditis or valvitis. CONCLUSION Echocardiography, when carried out in patients with acute rheumatic fever diagnosed strictly according to the Jones criterion, can avoid both overdiagnosis and underdiagnosis of carditis. A high incidence of carditis, or subclinical carditis, is detected by echocardiography when performed in patients with rheumatic chorea or arthralgia.

Abstract
Acute rheumatic fever (ARF) is an inflammatory disease of the heart, joints, CNS, and subcutaneous tissue that develops after a pharyngeal infection by one of the group A beta-hemolytic streptococci (Streptococcus pyogenes). The pathogenesis of the disease remains an enigma and specific treatment is not available, yet prevention of initial and recurrent attacks is possible by penicillin treatment. Rheumatic fever is especially important because of the heart disease that usually ensues; as succinctly stated by Lasegue many years ago, rheumatic fever "licks the joints and bites the heart", a statement that holds true today. Rheumatic fever is no longer a significant health problem in most socioeconomically advanced countries but it still causes 25-40% of all cardiovascular disease in the world, including tropical countries where it was once believed to be rare. In many countries it causes more hospital admissions than congenital heart conditions.ARF and rheumatic heart disease - with high associated morbidity, cost, and mortality - are largely preventable. Importantly, recurrences of rheumatic fever with their increased likelihood of more severe carditis are inexpensively preventable. Primary prevention has been achieved innovatively in some countries, for example, Costa Rica, and more conventionally in some developed countries. Treatment of the acute episode controls symptoms and may limit cardiac damage.

Abstract
Acute rheumatic fever (ARF) and its chronic sequela, rheumatic heart disease (RHD), have become rare in most affluent populations, but remain unchecked in developing countries and in some poor, mainly indigenous populations in wealthy countries. More than a century of research, mainly in North America and Europe, has improved our understanding of ARF and RHD. However, whether traditional views need to be updated in view of the epidemiological shift of the past 50 years is still to be established, and improved data from developing countries are needed. Doctors who work in populations with a high incidence of ARF are adapting existing diagnostic guidelines to increase their sensitivity. Group A streptococcal vaccines are still years away from being available and, even if the obstacles of serotype coverage and safety can be overcome, their cost could make them inaccessible to the populations that need them most. New approaches to primary prevention are needed given the limitations of primary prophylaxis as a population-based strategy. The most effective approach for control of ARF and RHD is secondary prophylaxis, which is best delivered as part of a coordinated control programme.

Abstract
OBJECTIVE Comparison of cardiac function in children with and without adenotonsillar hypertrophy. METHODS We examined 28 pediatric patients with adenotonsillar hypertrophy mean aged 7.3+/-2.9 years comprised of 14 females and 14 males (group I). The control group were chosen from 35 healthy sex and age matched children mean aged 7.37+/-2.7 years (group II). Both groups were examined by an otorhinolaryngologist and adenotonsillar hypertrophy was diagnosed with nasal endoscopic method or lateral neck X-ray. All the patients in group I underwent adenotonsillectomy. Cardiologic and echocardiographic examinations were performed in both groups. Echocardiographic examination was done twice in group I (preoperative and postoperative first month) however in group II only once. Preoperative findings of group I compared with the findings of group II. Preoperative and postoperative echocardiographic findings were also compared within group I. The chi-square test and the independent paired-sample t-test were used for statistical analysis. RESULTS The tricuspid end-diastolic time was the only significant difference in echocardiographic findings between the two groups (104.8+/-28.8 ms versus for 86.4+/-17.32 ms p<0.05). There was no statistical difference between preoperative and postoperative echocardiographic findings in group I. Brady-tachyarrhythmia was detected on electrocardiography - performed with 24h ambulatory electrocardiography - in one patient. To our surprise, in group I five patients had cardiac valve damage: mitral and/or aortic valve insufficiency. These findings were interpreted as silent carditis. CONCLUSION There was no significant difference in right ventricular function between the children with and without adenotonsillar hypertrophy. Whereas, there was shortening of tricuspid end-diastolic time in group I. However, five patients having adenotonsillar hypertrophy developed a cardiac dysfunction which was not observed in the control group. Therefore, we assumed a correlation between adenotonsillar hypertrophy and possible silent carditis following frequent tonsillitis.

Abstract
UNLABELLED The original Jones criteria, first introduced in 1944, have been modified four times and updated-revised criteria were published in 1992. A variety of clinical manifestations, which may be the presenting signs and symptoms of acute rheumatic fever, are not included in the updated-revised Jones criteria. A retrospective study was conducted on all children previously diagnosed to have acute rheumatic fever between September 1998 and September 2002. Review was focused on clinical presentation; out of 60 medical records reviewed, 4 patients with unusual clinical presentation were recognised and are reported here to highlight the potential diagnostic problems of acute rheumatic fever. They presented with atypical articular involvement, silent carditis and low-grade fever in the presence some time of a positive family history for rheumatic fever. CONCLUSION a high index of suspicion and an awareness of the absence of early carditis are necessary to make the diagnosis of acute rheumatic fever.

Abstract
OBJECTIVE To review our experience with children who presented with rheumatic fever (RF) before 5 years of age and to compare their presentation with that of older children. METHODS The cardiology database was reviewed to identify patients who were younger than 5 years and had a diagnosis RF using the Jones criteria from January 1985 through March 2000. Patient age, sex, date and age at presentation, and the major Jones criteria fulfilled were noted. When carditis was present, its severity was judged to be moderate to severe when there was radiographic cardiomegaly and/or clinical congestive heart failure. The clinical presentation of patients who presented in the first 5 years of life were compared with the presentation of those whose RF was diagnosed after 5 years of age. Clinical findings at follow-up evaluation and echocardiographic findings both at presentation and at follow-up were noted for the children who were younger than 5 years at presentation. RESULTS Of 541 cases of RF seen from January 1985 through March 20000, 27 (5%) were in children who were younger than 5 years (median: 4.0 years; range: 1.9-4.9 years). Major Jones criteria at presentation were arthritis in 17, carditis in 14, chorea in 3, and erythema marginatum in 3. The carditis was mild in 4 and moderate to severe in 10 patients. Compared with older children, younger children were more likely to present with moderate to severe carditis, arthritis without carditis or chorea, or the rash of erythema marginatum and were less likely to have chorea. The incidence of carditis was similar in the 2 groups as was the ratio of boys to girls. At follow-up (9.6 +/- 5.6 years), 69% of younger children who presented with carditis have clinical rheumatic heart disease. Subclinical, echocardiographically detected valvular abnormalities were detected both at presentation (33% of all children with RF before 5 years of age) and at follow-up (55% of those who initially had carditis). CONCLUSIONS Approximately 5% of children with RF were younger than 5 years at diagnosis. Compared with older patients, children who presented before 5 years of age were more likely to have moderate to severe carditis and to present with arthritis or the rash of erythema marginatum and were less likely to have chorea. Chronic rheumatic heart disease was common in young children who presented with carditis. Long-term follow-up is necessary to determine the outcome for young children with subclinical echocardiographic evidence of valvular disease.

Abstract
OBJECTIVE To determine the frequency of occurrence and long term evolution of subclinical carditis in patients with acute rheumatic fever. DESIGN Valvar incompetence was detected by clinical examination and Doppler echocardiographic imaging during the acute and quiescent phases of rheumatic fever. Patients were followed prospectively and submitted to repeat examinations at one and five years after the acute attack. Persistence of acute mitral and aortic lesions detected solely by echocardiography (subclinical disease) was compared with that of disease detected by clinical examination as well (thereby fulfilling the latest 1992 Jones criteria for rheumatic carditis). SETTING Three general hospitals with a university affiliation in Chile. PATIENTS 35 consecutive patients fulfilling the revised Jones criteria for rheumatic fever. Clinical and echocardiographic examination was repeated in 32 patients after one year and in 17 after five years. Ten patients had subclinical carditis on admission, six of whom were followed for five years. MAIN OUTCOME MEASURES Auscultatory and echocardiographic evidence of mitral or aortic regurgitation during the acute attack or at follow up. RESULTS Mitral or aortic regurgitation was detected by Doppler echocardiographic imaging in 25/35 rheumatic fever patients as opposed to 5/35 by clinical examination (p = 0.03). Doppler echocardiography revealed acute valvar lesions in 10 of 20 rheumatic fever patients who had no auscultatory evidence of rheumatic carditis (subclinical carditis). Three of these subclinical lesions and three of the clinical or auscultatory lesions detected on admission were still present after five years of follow up, emphasising that subclinical lesions are not necessarily transient. CONCLUSIONS Doppler echocardiographic imaging improves the detection of rheumatic carditis. Subclinical valve lesions, detected only by Doppler imaging, can persist. Echocardiographic findings should be accepted as a major criterion for the diagnosis of rheumatic fever.

Abstract
BACKGROUND Acute rheumatic fever (ARF) remains the leading cause of acquired heart disease in children worldwide. No therapeutic agent has been shown to alter the clinical outcome of the acute illness. Immunological mechanisms appear to be involved in the pathogenesis of ARF. Intravenous immunoglobulin (IVIG), a proven immunomodulator, may benefit cardiac conditions of an autoimmune nature. We investigated whether IVIG modified the natural history of ARF by reducing the extent and severity of carditis. METHODS AND RESULTS This prospective, double-blind, randomized, placebo-controlled trial evaluated IVIG in patients with a first episode of rheumatic fever, stratifying patients by the presence and severity of carditis before randomization. Patients were randomly allocated to receive 1 g/kg IVIG on days 1 and 2 and 0.4 g/kg on days 14 and 28, or they received a placebo infusion. Clinical, laboratory, and echocardiographic evaluation was performed at 0, 2, 4, 6, 26, and 52 weeks. Fifty-nine patients were treated, of whom 39 had carditis (including 4 subclinical) and/or migratory polyarthritis (n=39). There was no difference between groups in the rate of normalization of the erythrocyte sedimentation rate or acute-phase proteins at the 6-week follow-up. On echocardiography, 59% in the IVIG group and 69% in the placebo group had carditis at baseline. There was no significant difference in the cardiac outcome, including the proportion of valves involved, or in the severity of valvar regurgitation at 1 year. At 1 year, 41% of the IVIG and 50% of the placebo group had carditis. CONCLUSIONS IVIG did not alter the natural history of ARF, with no detectable difference in the clinical, laboratory, or echocardiographic parameters of the disease process during the subsequent 12 months.

Abstract
OBJECTIVES The purpose of this study was to characterize left ventricular (LV) mechanics during acute rheumatic fever (ARF) and to define factors influencing remodeling after the acute event. BACKGROUND Acute rheumatic fever is associated with varying degrees of valvulitis and myocarditis, but the impact of these factors on LV mechanics is poorly defined. METHODS Echocardiograms and clinical data were reviewed in 55 patients aged 11.2 +/- 2.6 years during ARF. Valve regurgitation was absent or mild in 33 (group I) and moderate or severe in 22 (group II). Forty-two children (75%) underwent a further examination after ARF. RESULTS Group I patients demonstrated a mildly elevated LV size during ARF and had normal indexes at follow-up. Group II patients demonstrated a markedly elevated LV size (end-diastolic dimension z-score 3.6 +/- 1.8, p < 0.01 compared with the normal population) and decreased shortening fraction (z-score -0.8 +/- 1.4, p < 0.05). The stress-velocity index, a z-score describing the velocity of shortening-afterload relationship, was normal in group II patients with mitral regurgitation (-0.2 +/- 1.2, p = NS) but was depressed in those with aortic regurgitation or both (- 1.4 +/- 1.4, p < 0.01). At follow-up the stress-velocity index remained depressed (-1.2 +/- 1.0, p < 0.01) and had deteriorated in those treated nonsurgically compared with those treated surgically (interval change nonsurgical -0.7 +/- 1.2 vs. surgical 1.3 +/- 1.3, p = 0.005). CONCLUSIONS The evolution of contractile dysfunction during and after ARF is dependent on the degree and type of valve regurgitation and may be influenced by surgical intervention. These findings suggest that mechanical factors are the most important contributors to myocardial damage during and after ARF.

Abstract
BACKGROUND The diagnosis of rheumatic fever is based on physical findings (major) and supporting laboratory evidence (minor) as defined by the Jones criteria. Rheumatic carditis is characterized by auscultation of a mitral regurgitant murmur. Doppler echocardiography, however, may detect mitral regurgitation when there is no murmur ("silent" mitral regurgitation), even in normal individuals. HYPOTHESIS The hypothesis of this study was that physiologic mitral regurgitation can be differentiated from pathologic "silent" mitral regurgitation by Doppler echocardiography. METHODS The study group consisted of 68 patients (2-27 years) with normal two-dimensional imaging and Doppler evidence of mitral regurgitation but no murmur. Patients with rheumatic fever (n = 37) met Jones criteria (chorea in 20, arthritis in 17). Patients without rheumatic fever (n = 31) were referred for innocent murmur (n = 7), abnormal electrocardiogram (n = 13), and chest pain (n = 11). Echoes were independently reviewed by two cardiologists blinded to the diagnosis. Pathologic mitral regurgitation was defined as meeting the following four criteria: (1) length of color jet > 1 cm, (2) color jet identified in at least two planes, (3) mosaic color jet, and (4) persistence of the jet throughout systole. Jet orientation was also noted. RESULTS Using the above criteria, there was agreement in echo interpretation of pathologic versus physiologic mitral regurgitation in 67 of 68 patients (interobserver variability of 1.5%). Pathologic regurgitation was found in 25 (68%) patients with rheumatic fever but in only 2 (6.5%) patients without rheumatic fever (p < 0.001). The specificity of Doppler for detecting pathologic regurgitation was 94% with a positive predictive value of 93%. The color mitral regurgitant jet was posteriorly directed in all 25 patients with rheumatic fever. CONCLUSION Pathologic "silent" mitral regurgitation of rheumatic fever can be distinguished from physiologic mitral regurgitation using strict Doppler criteria, particularly when the jet is directed posteriorly. These data support the use of Doppler echocardiography as a minor criterion for evaluating patients with suspected rheumatic fever.
