[II-JCK03-2] PDA closure in premature infants
Transcatheter closure of PDA has been extended to preterm infants with hemodynamically significant PDA due to the advances in device design, the establishment of an exclusive transvenous procedure, and cumulative experiences. In the past decade, several intervention teams from many different countries have reported encouraging results using various devices. The cardiac catheterization intervention team of National Taiwan University Children’s Hospital started prematurity PDA closure program in 2016. Our initial experience was published last year (Int J Cardiol. 2020;312:50-55), and proposed several novel and clinically significant concepts related to this procedure. The observation that the implanted device might experience deformation at follow-up, probably related to ductus constriction, may have great impacts on both device selection and deployment technique. It is important to note that this is not a procedure with neglectable risks. To achieve the best result of this intervention, there must be a good match between patients, PDA morphology, and the devices chosen for closure. Before conducting a randomized control study comparing with the surgery and conservative treatment, measures to minimize any potential complications inherited to the procedure/device must be undertaken for every intervention team dedicated to this novel treatment option.
