Impact of Persistent Left Superior Vena Cava Detection in a Normal Neonatal Population through Echocardiography.

Based on the echocardiography examination results, we discovered that the incidence of PLSVC in Taiwanese neonates was 0.29%. Although the neonates with PLSVC were asymptomatic and exhibited no health concerns, they were associated with higher incidence rates of bicuspid aortic valves and secundum-type atrial defects. Additional follow-up and evaluation regarding these findings may be warranted.
