“…Isolated VSD was the most prevalent acyanotic CHD. This matches with most of the previous studies [3,8,15], whereas tetralogy of Fallot was the most frequent cyanotic CHD, which is also in agreement with most of the available studies [16][17][18].…”

Background Congenital heart disease (CHD) is a multifactorial birth defect which has variable demographic characteristics among children in different geographical areas. This study aimed to detect the distribution of demographic data, perinatal risk factors, types, age, and mode of presentation of CHD among Egyptian children. Results The medical records of 1005 patients were included. They were 545 males (54%) and 462 females (46%) with a ratio of 1.2:1. Acyanotic CHD was encountered in 79.2%. Isolated ventricular septal defect and tetralogy of Fallot were the most common acyanotic and cyanotic lesions, respectively. The majority was diagnosed within the first year of life (86.7%) and was born to young mothers (91.3%). The accidental discovery of a murmur was the most frequent presentation (35%). Heart failure was detected in 44%, audible murmurs in 74.4%, maternal illnesses in 54%, consanguinity in 44.6%, prematurity in 19.3%, assisted reproduction in 11.7%, family history of CHD in 9.2%, abortions in 7.1%, and extracardiac anomalies in 3.6% of the studied population. Down syndrome (DS) was the most commonly occurring chromosomal anomaly, and the atrioventricular septal defect was the most characteristic cardiac lesion found among them. Conclusions There is no sex predilection among Egyptian children with CHD. Most of the cases are diagnosed in early infancy. Accidental discovery of a murmur is the most common mode of presentation. A variety of predisposing risk factors are abundant in the Egyptian population. DS is the most common chromosomal anomaly linked to CHD. Establishment of a national medical birth registry containing all information about all births in Egypt is needed for adequate surveillance and monitoring of perinatal health problems and congenital birth defects so that preventive measures can be early implemented. Proper and detailed data collection should be fulfilled in the medical records of every single patient.

“…In our study, acyanotic CHDs form a major chunk (n=149) 85.6% of total CHDs, which is in congruent with other studies [3,11]. ASD was most common accounting for 35% of total cases, either isolated (n=52) 30% or in combination with VSD (n=10) 5.7%; which is similar to some studies [14,15] and in contrast to several studies where VSD is comparatively common.…”

“…Right sided pulmonic obstructive lesions like TOF and PS were more commonly observed than Left Ventricular Obstructive Lesions like Coarctation and AS, which are in accordance with other studies in India.The rare and complex CHDs like Cortriatrium, HLHS, TAPVC and Ebstien Anomaly were found one case each, which are known to have very low frequency. This observance is similar to that found in studies conducted in Mysore and Uttarakhand [6,11].…”

“…Studies from India [5][6][7][8][9][10][11][12], have reported a wide variation in prevalence of CHD from 2.25 to 26.3 per 1000 live births, depending on the type of study being performed [6,10,11,13]. For instance, hospital based studies may have a higher prevalence as new-borns are included, in whom, the number of trivial lesions are high, while [5,7] school based studies may show lower prevalence.…”

Objective: To evaluate the spectrum and pattern of congenital heart diseases in NRI general hospital, a tertiary care teaching hospital, Chinna Kakani, Andhra Pradesh. Methods: A retrospective hospital based analysis of children attending pediatric department over a period of two years during January, 2014 to December, 2015 was performed. Patients suspected to have cardiac symptoms or cardiac murmurs were referred for 2D echo and colour Doppler to confirm the diagnosis. Prevalence rate per 1000 patients was calculated. Relative frequencies of individual CHD types as a proportion of total CHDs were also calculated. Results: A total of 174 Echo confirmed cases of CHDs were identified from a total of 60,000 patients attending the hospital over a two year period with a calculated prevalence of 2.9/1000 patients. Of total cases 96 were female and 78 were male children. A total of 149 Acyanotic CHD cases (86.5%) were identified of which, Isolated ASD were 52 (35%), Isolated VSD were 42 (28%), AVCD were 2 (1.34%), PS were 12 (8%), AS were 4 (2.7%), COA were 2 (1.34%), PDA were22 (14.7%), combination of ASD + VSD were 10 (6.7%) and Dextrocardia with situs inversus were 3 (2%). A total of 25 cases of Cyanotic CHD were identified, of which TOF and its variants were 16 (64%), DORV+VSD+PS were 2 (8%), rare complex CHDs like DORV+HLHS, TAPVC, Ebstien Anomaly, Cortriatrium, were one case (4%) each and TGA were 3 (12%) cases. Conclusion: The calculated prevalence of CHD at 2.9 /1000 among hospital attending patients could be an underestimation of actual disease burden in our community. The maximum numbers of children with CHD were identified by 5 years of age. The most commonly found Acyanotic CHDs were ASD, VSD and PDA. The most common cyanotic CHD was TOF.

“…With a prevalence of 9 per 1000, approximately 1.35 million newborns are born with CHD every year globally [ 5 ]. The prevalence of CHD in India in recent studies reports an increased prevalence of 8.5-13.6 per 1000 children [ 6 , 7 ]. In India, CHD contributes significantly to infant mortality (10%) [ 8 ].…”

Introduction: Congenital heart disease (CHD) is an abnormality in the structure or function of the cardiocirculatory system present at birth but more often diagnosed subsequently. CHD is the most common (28%) major congenital anomaly and thus signifies a major global health problem. The primary objective is to estimate the frequency and pattern of CHD in children in the Andaman and Nicobar Islands (India).Methods: We did a hospital-based retrospective observational study. The hospital case records of all children belonging to the age group of 0 to 12 years with newly diagnosed CHD were reviewed for the five years from January 1, 2016 to December 31, 2020. The clinical, demographic, and echocardiogram details were retrieved, and descriptive analysis was done using the Statistical Package for the Social Sciences (SPSS) for Windows Version 26 (IBM, Chicago, USA).Results: A total of 201 (12.8 per 1000) children were newly diagnosed with CHD (out of a total of 15592 children). There were 110 (54.7%) boys and 91 (45.3%) girls in the age group of 0 to 144 months (mean ± SD: 13.86±27.13). The ventricular septal defect (VSD) is the most common congenital heart defect, accounting for 25.4% of all CHD cases. The most common cyanotic CHD was tetralogy of Fallot (TOF), comprising 8% of the total cases. Conclusion:The spectrum of CHD in our study was largely similar to pre-existing literature. Although most of the CHDs were detected during infancy, a higher proportion of complex lesions in our study group resulted in adverse outcomes, even in surgically managed cases.
