Abstract
This study was to investigate the value of echocardiographic data in assessing changes in cardiac function before and after transcatheter closure in children and adult patients with patent ductus arteriosus (PDA). In this study, 150 patients with isolated PDA treated by cardiac catheterization and transcatheter closure were selected as the study sample. Real-time color Doppler echocardiography was used both after and after operation. The results showed that the left ventricle returned to normal in 75 patients one day after operation, with an average age of 10.95 ± 3.27 years; the left ventricle did not return to normal in 10 patients 360 days after operation, with an average age of 64.31 ± 7.05 years. Left ventricular end diastolic volume index (LVEDVI) and left ventricular end systolic volume index (LVESVI) of patients decreased significantly one day after operation and remained at 51.95 ± 9.55 mL/m2 and 20.36 ± 8.11 mL/m−2, respectively. In summary, echocardiographic data have a high reference value in assessing cardiac function characteristics in children and adult patients with PDA and are worthy of further promotion.

This study hopes to analyze the changes of cardiac function and the diagnostic value of echocardiography before and after transcatheter closure of PDA in children and adults by performing echocardiography and cardiac function assessment in 150 patients with isolated PDA treated by cardiac catheterization and transcatheter closure
150 patients with isolated PDA diagnosed in Quanzhou First Hospital Affiliated to Fujian Medical University and Fujian Medical University Union Hospital from January 1, 2016, to January 5, 2021, were selected as research samples, aged 6-70 years, all of whom were successfully treated with cardiac catheterization and transcatheter closure under local anesthesia
Summary
Patent ductus arteriosus (PDA) is one of the common types of congenital heart disease in children, accounting for 15% of the total incidence of congenital heart disease. By 1 year, anatomically, it should be completely closed If it continues to open and produces pathological and physiological changes, it is called PDA [4]. The clinical manifestations of the disease mainly depend on the amount of blood flow from aorta to pulmonary artery and whether secondary pulmonary hypertension occurs and its degree. If it is mild degree, there are no obvious symptoms, and if it is severe degree, heart failure can occur [5, 6]. During a physical examination for PDA, the typical sign is a loud continuous machine-like murmur heard in the second intercostal space on the left sternal border, accompanied by tremors. The current study concluded that the characteristics of cardiac function in patients with PDA are characterized by heart
