Mind the gap‐missing device on the shelf? Retrospective experience with 5/7 Occlutech duct Occluder

Abstract

AbstractAimTo describe our initial experience with the indications and results of the 5/7 Occlutech® duct Occluder (ODO, Occlutech International AB, Helsingborg, Sweden). A small incremental increase in occluder sizes is of utmost importance for successful outcomes, especially in smaller patients in whom protrusion of the distal disk towards the aorta should be minimised.MethodsRetrospective study of all patients undergoing PDA closure with the 5/7 ODO in three institutions since 2018.ResultsThe 5/7 ODO was used in 18 patients with median age and weight at the time of the procedure of 17.5 months (interquartile range 25th to 75th percentile 8 months– 4.4 years) and 13.6 kg (interquartile range 25th to 75th percentile 6.4–22.5 kg) respectively. All cases were successful. There were no cases of device embolisation, haemolysis, or flow disturbance of the LPA or the aorta.ConclusionsThis small retrospective study demonstrated an excellent outcome of transcatheter PDA closure with the 5/7 ODO. The device is a beneficial complement to the existing sizes of PDA devices, filling the gap between the 4/6 and 6/8 ODO and avoiding protrusion of a larger disk in the aortic isthmus.
