Abstract
Eisenmenger syndrome is a life-threatening complication of congenital heart defects (CHD). Since Eisenmenger syndrome among children of repaired CHD is rare, very few studies have had the necessary data to investigate its distribution in children. The current study used data collected in rural China to investigate the prevalence of Eisenmenger syndrome in children with unrepaired CHD. Data were from the 2006 to 2016 patient medical records of China California Heart Watch, which is a traveling cardiology clinic in Yunnan Province, China. Patients were included if they (1) aged 18 or below, (2) had CHD(s), and (3) the defect was not repaired by the time of the clinic visit. The prevalence of Eisenmenger syndrome was calculated in each age and defect group. Using logistic regression models, we tested whether oxygen saturation, Down syndrome, sex, and age were significantly associated with Eisenmenger syndrome. Of the 1301 study participants, ventricular septum defect (VSD), atrial septal defect (ASD), and patent ductus arteriosus (PDA) were the most common CHD. About one-sixth of the patients had pulmonary hypertension and 1.5% had Eisenmenger syndrome. The percentages of Eisenmenger syndrome were 1.8% in VSD patients, 0 in ASD patients, and 0.9% in PDA patients. Patients in the age group between 15 and 18 years had the highest percentages of Eisenmenger syndrome (11.5%). Age and presence of Down syndrome were significantly associated with the presence of Eisenmenger syndrome. Our finding highlights the importance of early detection and correction of CHD.
