Clinical Value of Echocardiographic Screening and Dynamic Observations for Ductus Arteriosus Closure in Newborns

Abstract

Objective: To explore and analyze the clinical value of echocardiography screening and dynamic observation for ductus arteriosus closure in newborns. Methods: The study was conducted from August 2022 to December 2023. 500 newborns who were admitted to our hospital were selected as research subjects for this study (Kunming Tongren Hospital). All subjects underwent echocardiography to determine the severity of patent ductus arteriosus (PDA). The inner diameter of the pulmonary artery was measured, and the pulmonary artery pressure was estimated through tricuspid regurgitation. If the patient had high pulmonary artery pressure, elective closure surgery was performed. Results: Among the 500 subjects, 448 cases of ductus arteriosus closure and 52 cases of PDA were detected by echocardiography, including 23 cases of simple PDA, 15 cases with patent foramen ovale, 11 cases with atrial septal defect, 1 case with muscular ventricular septal defect, 1 case with tricuspid valve prolapse, and 1 case with tricuspid valve chordae tendineae rupture. After symptomatic treatment and intervention, their echocardiogram results were reviewed and no abnormalities were found. All measurement results of children with PDA combined with pulmonary hypertension were better than before treatment (P < 0.05). Conclusion: Echocardiography is a fast, accurate, and reliable non-invasive imaging examination technology. It can significantly improve congenital heart disease detection rate in infants and young children. Early intervention based on the examination results can dramatically improve the quality of life of infants and young children with PDA.
