Echocardiographic Parameters of Severity in Isolated Neonatal Patent Ductus Arteriosus
Pediatric Sciences Journal(2021)
摘要
Background: A hemodynamically-significant patent ductus arteriosus (hsPDA) compromises the early neonatal transition. There is no general agreement on echocardiographic indicators of hsPDA that can predict clinical decompensation. Aim of the Work: We aimed to assess echocardiographic parameters that are associated with the isolated PDA effects on hemodynamics, which could help in subsequent management decision making. Materials and Methods: We conducted a prospective observational analytical study on 50 neonates with isolated PDA and 20 controls. They underwent clinical and echocardiographic assessment at 48 hours of age, after another 48-72 hours and prior to discharge. Results: No correlation was found between PDA diameter and weight (p=0.72), length (p=0.11), Body surface area (BSA) (p=0.33), gestational age (p=0.13). A strong association of PDA-related hemodynamic instability was found with pulmonary hypertension (p= Conclusion: Pulmonary hypertension, larger LA Z-score and LPA Z-scores are important early (at 48 hours) associations of a hsPDA and hemodynamic instability.
