Echocardiographic guidance for transcatheter patent ductus arteriosus closure in extremely low birth weight infants

摘要

Abstract Echocardiographic imaging provides real‐time guidance during transcatheter patent ductus arteriosus (PDA) closure in extremely low birth weight (ELBW) infants. Transthoracic echocardiogram provides detailed assessment of the PDA and surrounding structures prior to, during, and after transcatheter closure. This article aims to review the different echocardiographic techniques and concepts utilized during transcatheter PDA closure in ELBW infants.
