BACKGROUND Screening for congenital heart disease (CHD) in school students is well-established in high-income countries; however, data from low-to-middle-income countries including Indonesia are limited. AIM This study aimed to evaluate CHD screening methods by cardiac auscultation and 12-lead electrocardiogram to obtain the prevalence of CHD, confirmed by transthoracic echocardiography, among Indonesian school students. METHODS We conducted a screening programme in elementary school students in the Province of Special Region of Yogyakarta, Indonesia. The CHD screening was integrated into the annual health screening. The trained general practitioners and nurses participated in the screening. The primary screening was by cardiac auscultation and 12-lead electrocardiogram. The secondary screening was by transthoracic echocardiography performed on school students with abnormal findings in the primary screening. RESULTS A total of 6116 school students were screened within a 2-year perio...
Evaluation of heart murmurs in children: One year of observational study
Egyptian Pediatric Association Gazette, 2015
This prospective study aimed to evaluate the heart murmurs and nature of heart disease found among new referral of children at pediatric outpatient clinics of Sohag University hospital. The study depended on Doppler echocardiography as a diagnostic standard for differentiation of heart murmurs and precise evaluation of innocent murmurs. Methods: The study was conducted on 183 patients with heart murmur from 6 weeks to 12 years old for new referral at pediatric outpatient clinics for 1 year. All patients underwent cardiac auscultatory examinations and Doppler echocardiography examination. Results: Of 183 patients, 97 children were males (53.28%). Innocent murmurs were found in 98 patients (53%) and pathological murmurs in 85 patients (47%). The most common pathological murmur is VSD (23%), followed by RHD (MR) (12%). There was no statistically significant difference between innocent and pathological murmurs regarding age, sex, consanguinity and other sibling who had CHD as in Table 3. Conclusions: Several healthy children are referred to pediatric cardiologists or for echocardiographic examination. Physician anxiety is an important reason for a referral of the children to pediatric cardiologists. Echocardiography provides a definitive diagnosis and is recommended for evaluation of any potentially pathologic murmur, and for evaluation of infant heart murmurs because these are more likely to be manifestations of structural heart disease. Cardiac examination should remain the first line diagnostic tool of every clinician; echocardiography should not replace it.

The aim of this study was to assess whether cardiac auscultation performed by pediatric trainees and neonatologists can reliably distinguish innocent from pathologic heart murmurs in asymptomatic neonates. From January 2008 to April 2009 the pediatric trainees of our institution were requested to refer all asymptomatic neonates with a murmur and classify the murmurs as ''innocent,'' ''pathologic,'' or ''possibly pathologic.'' Prior to echocardiography, each neonate was evaluated by two experienced neonatologists. The echocardiographic studies of 169 neonates were analyzed. Abnormal cardiac anatomy was found in 55 neonates (32.6%). The overall ability of pediatric trainees in identifying congenital heart disease (CHD) was moderate [area under the curve (AUC) = 0.855] and significantly lower compared to neonatologists (AUC = 0.919, p = 0.007). However, at ''lower'' levels of clinical confidence (i.e., clinical diagnosis of possibly pathologic murmurs), pediatric trainees had good ability in excluding CHD (sensitivity 94.6%; negative likelihood ratio = 0.09). The ability of cardiac auscultation for diagnosing CHD in asymptomatic neonates is limited and dependent on the physician's experience and level of clinical confidence. Echocardiography should remain an option for all neonates with a possibly pathologic murmur.
Evaluation of Diagnostic Methods in the Differentiation of Heart Murmurs in Children
Acta informatica medica : AIM : journal of the Society for Medical Informatics of Bosnia & Herzegovina : časopis Društva za medicinsku informatiku BiH, 2016
The most common clinical sign in pediatric cardiology is a heart murmur (organic and inorganic). Organic are sign of heart disease, while inorganic (basically divided into accidental and functional) murmurs occur on anatomically healthy heart. To determine the justification of the application of the methods of cardiac treatment. Study included 116 children aged from 1 to 15 years, who were referred due to cardiac treatment to Pediatric Clinic, of Sarajevo University Clinical Center. The first group consisted of children with innocent heart murmur, 97 (53 males). The second group consisted of patients with organic murmur, 19 (13 males). The average age of the first group was 7.69 (1.01-15.01) years old, and of the second group 3.15 (1.01- 8.06) years old, and there is a significant difference between these two groups (p <0.001). Medical history questions about potentially harmful habits of mother in pregnancy, found significant differences in the frequency of the existence of habi...

Background Congenital heart diseases (CHD) cause declining of functional capacity, cyanosis, arrhythmia, stroke, and death in adulthood. The screening for congenital heart disease in children has not been established in Indonesia. This results in a relatively high prevalence of uncorrected CHD in adulthood, who mostly have developed pulmonary artery hypertension. The screening program by cardiac auscultation and electrocardiography (ECG) in schoolchildren has been proven to be feasible in developed countries, which may also be feasible in Indonesia.Aim This study was planned to test and assess CHD screening methods based on electrocardiography examination in school children.Methods We conducted a screening program in first grade elementary school children in the Province of Yogyakarta, Indonesia. The schools were determined by purposive sampling. Trained general practitioners in community health centers participated in the screening. The physical examinations were done, which focuse...
A comparison of clinical paediatric murmur assessment with echocardiography
2004
29 Abstract Objective: To compare the clinical acumen of paediatric cardiovascular examination between various hospital paediatrician grades. Design: Prospective data collection of clinical and echocardiography findings on paediatric echocardiography referrals. Setting and patients: All paediatric patients (birth 14 years) referred for echocardiography, in a regional hospital catering for the island population of Malta. Echocardiography was carried out by three paediatricians with tertiary training in this technique. Main outcome measures: Pre-echocardiography clinical diagnoses were compared with echocardiography results according to grade of referring hospital doctor (ranging from houseman to consultant). Both normal and abnormal hearts at echocardiography were included. Results: Echocardiographers had the highest clinical accuracy and the highest attempts at reaching a clinical diagnosis. Accuracy and attempts at diagnosis decreased as doctor’s hospital grade decreased, from cons...

The objective of this study was to compare the accuracy of the expert clinical examination for certain common cardiac defects with and without electrocardiogram (EKG) and chest radiogram (x-ray). The design of the study was a prospective, blinded comparison of diagnostic accuracy of the expert examination with and without EKG and x-ray, using echocardiography as the diagnostic standard. The setting of the study was the pediatric cardiology outpatient department. There were 749 outpatients with heart murmur under 21 years of age without prior echocardiography or pediatric cardiology consultation. The intervention was echocardiography as clinically indicated for evaluation of heart murmur of uncertain cause. Measurements were carried out using the incorporation of EKG and x-ray into multiple linear regression models to assess independent associations, if any, with the accuracy of clinical examination. Results were reported as the presence or absence of independent significant impact of availability of EKG and x-ray on examiner's diagnostic accuracy for innocent murmur, ventricular septal defect (VSD), pulmonary stenosis (PS), aortic valve disease, atrial septal defect (ASD), and patent ductus arteriosus. EKG enhanced detection of ASD and may have helped detect PS. X-ray enhanced detection of intermediate to large VSD. X-ray and EKG were otherwise without demonstrable independent advantage for defect-specific diagnosis. Routine use of one or both of these tests in the initial evaluation of heart murmur in the pediatric cardiology clinic should remain an option.
Echocardiographic Yield in Children When Innocent Murmur Seems Likely But Doubts Linger
Pediatric Cardiology, 2002
The objective of our study was to determine the incidence and nature of heart disease found among children with murmurs clinically ambiguous to an expert examiner. The study was a prospective, blinded evaluation of accuracy of the expert examination using echocardiography as the diagnostic standard. The setting of the study was a pediatric cardiology outpatient department. The study comprised 903 outpatients with heart murmur under 21 years old without prior echocardiography or pediatric cardiology consultation. The intervention was echocardiography as clinically indicated for evaluation of heart murmur of uncertain cause. The outcome measure were a comparison of clinical diagnoses with echocardiographic results. In this clinical population, the presence of heart disease correlated with young age at presentation and with the expert examiner's level of suspicion of heart disease. However, 16 of 187 cases in which speci®c pathology was unsuspected had disease, and 6 of these 16 have had catheter or surgical intervention. Fourteen of the 16 unsuspected had objective indications for echocardiography and the other 2 were examined to allay anxiety. When evaluating very young outpatients with innocent-sounding murmur or older outpatients with innocent-sounding murmur and disconcerting symptoms, signs, or laboratory results, pediatric cardiologists should have a low threshold for echocardiography. Older outpatients with innocent-sounding murmur seldom have heart disease when anxiety is the only indication for echocardiography.
Background: Heart diseases of childhood are of public health importance, especially in developing countries. Community-based studies are important in ascertaining the burden of disease. We set out to clinically evaluate the prevalence of heart disease among primary school children in Hwolshe electoral Ward, Jos, Plateau State. Subjects and Methods: A total of 418 primary school pupils were selected by multistage sampling from three schools in Hwolshe ward of Jos South Local Government Area, Plateau State. They were studied for the prevalence of heart disease using clinical examination, followed by chest radiography, electrocardiography and echocardiography (echo) in those with clinical signs of heart disease. Results: The 418 subjects were aged 6-12 (mean 9.0 ± 1.95) years. 252 (55.5%) were girls. Significant tachycardia and pulse irregularity were present in 1 (0.24%) and 3 (0.72%) children respectively. None had hypertension-according to the seventh Joint National Committee criteria. 4 (0.96%) had audible murmurs of which 3 (0.72%) were pathologic. These three subjects were subsequently confirmed by echo to have congenital heart disease (CHD)-two ventricular septal defects and one atrial septal defect. The heart disease prevalence was therefore, 0.72%. All three identified cases of CHD had associated cardiac dysrhythmias: Wandering atrial pacemaker, first degree heart block, and incomplete right bundle branch block, respectively. No case of rheumatic heart disease was identified. Conclusions: Prevalence of heart disease by clinical screening in Jos South school children is approximately 0.72%. Careful cardiac auscultation as part of compulsory health screening at primary school entry and exit will help detect asymptomatic children with heart disease and facilitate treatment before the onset of complications.

Background: Congenital heart diseases (CHDs)are an important cause of morbidity and mortality in children. In view of poor availability of resources in developing nations like India, clinical evaluation of children with CHD is important. Aim: To study the clinical accuracy of post graduate student in diagnosing congenital heart diseases and its comparison with echocardiography. Subjects and Methods: A prospective cross-sectional study performed in the Department ofPediatrics of a tertiary level teaching hospital in central India. Participants were children with CHDs attending outpatient department or admitted in wards or PICU. History, general physical and cardiovascular examinations were recorded by the post graduate student. Chest X-ray and ECG were obtained. These findings were used to classify the defect using an algorithm and a clinical diagnosis was made which was matched with echocardiography.Kappa coefficient test was used to judge the degree of agreement between the two methods. Results: 80 patients with CHDs were included in the final analysis. 49 (61.25%) had acyanotic CHDs and ventricular septal defect (VSD) was the most common defect (n= 24, 30%) while tetralogy of Fallot (TOF) was the most common (n=14, 17.5%) cyanotic CHD. Concordance of clinical diagnosis and echocardiography was maximum for VSD (16/24, 66.6%) in acyanotic group and TOF (8/14, 57%) in cyanotic group. Kappa's coefficient test analysis also showed an "almost perfect" area of agreement for VSD (κ=0.87) and fair area of agreement for TOF (κ=0.65). For type of CHD (cyanotic or acyanotic) and type of ventricular hypertrophy (left, right or biventricular) it showed "almost perfect" and"fair" area of agreement respectively. Conclusion: Agreement between echocardiography and cclinical diagnosis of CHDs including hemodynamic parameters like type of ventricular hypertrophy and pulmonary arterial hypertension was reasonably accurate in our study.
